Heat pumps can’t take the cold? Nordics debunk the myth::By installing a heat pump in his house in the hills of Oslo, Oyvind Solstad killed three birds with one stone, improving his comfort, finances and climate footprint.

Good Lord - $2600 for a whole house system? I think that’s what my local (mid-Atlantic US) HVAC shop is getting for a single-room mini-split.
Wait until people find out about ground-source heat pumps and water heater heat pumps. What you get out of those is more consistent year round, too. It’s almost like leveraging technology has benefits over just burning carbon and hydrogen to make heat.
2600 is dirt cheap even by Euro standards, trust me.
Here in Italy a single room split would cost you around 1k to 2.5-3k depending on the brand.
A whole house system you’re probably looking at 10k and then some.
I got a quote in rural America for a single room minisplit, $10,300.
Absolutely bonkers.
That is absolutely bonkers. I put one in myself for my one room garage that I converted to a place to hang. Cost 720$ after tax for a Pioneer mini split. It’s entering its third year in use and I love it. That being said, I wouldn’t be so risky as to put my own in when its task was heating or cooling my home. Just my garage is my problem, the rest is my family, and so I paid. But I got a whole home solution, two floors, Carrier units, for about $15k.
I believe what you’re looking for is out there and not ridiculous price.
The guy you quoted just want to make his monthly paycheck on you alone, because that’s way over anything reasonable
Also in rural America. How did you get someone not to laugh at you when you asked? God I fucking hate the small mindedness around me, but I couldn’t stand the city either. I cannot find someone to put one in my house so I’m going to have to install it myself next summer.

You’re just repeating what all the gas installers keeep repeating so they don’t lose business.
Every House built after 1990 or houses that have had insulation makovers in the past 20 years are perfectly fine to heat with a heatpump.deleted by creator
$2600 is utter bullshit. I had several quotes for a 1000sf house, not a single one was under 16000 installed, after rebates. My payback period was going to be almost 20 years even against a medium efficiency gas furnace.
And this is why the comments here miss the point- sure, heat pumps nowadays can work that low but in a lot of places the payoff period is well outside what anyone is looking at.
Half of my house was 8k, the other side I’m planning to install myself because I don’t have that kind of money just waiting to be spent anymore.
Even the Diy mini splits, you’re paying $600 to $1000 easily for just one single unit.
Paid $6700 in May to replace mine.
I don’t think Geothermal makes much sense unless you live in one of the extremes, mainly the cold one, For example I an from Slovakia and I don’t think the temperature here went under -20C in the last few years, I barely remember any days going under - 10C, so you would be paying quite a premium for a geothermal heat pump for rather marginal gains, it would certainly need quite a good analysis if the difference in performance would ever pay for the price difference, especially with better insulation and heat recuperation systems becoming mandatory.
There are also things like heat pump based driers now on the market btw.
I suspect it’s mostly a function of mass availability. Even here in the states ground source heatpumps are rare, even though the systems are more reliable (since there is no equipment exposed to weather) and a shallow borehole isn’t excessively expensive.
I’d forgotten about heat pump clothes dryers. Those are fascinating, and really interesting for older buildings or locations without close access to exterior venting.
Shallow geothermal is basically dead in most of the world because it’s too much hit and miss, the geology is simply too complex and involved (and underground) to predict. There’s also a fuckton of issues with water ingress, minerals that like to expand when getting wet and such. You can’t really take Iceland as an example for countries not straddling a continental rift.
Deep geothermal is utterly reliable but for the longest time drilling that deep was just too expensive. Plasma deep drilling is a solution but it’s still in its infancy.
that’s not the geothermal we are talking about, geothermal heat pumps
Those are ground source heat pumps.
Seriously by that nomenclature we’d also have aerothermal heat pumps.
Wow that’s really pricey. Here in Malaysia a 2 HP mini split with inverter costs roughly RM 2400 including installation (around $500).
Granted the average salary here is much lower but it’s amazing how much the prices differ given that they all basically come from the same factory.
Hell yeah, we’ve got a heat pump and we’re in Canada where it can get to -40°C (which is coincidentally also -40°F) and that thing works like a beast. Fortunately we also have the cheapest electricity in North America so the decision was easy.
What’s your heat pump? I’ve been looking into them and I can’t find one that’s willing to say it works past about -15.
The Mitsubishi Hyper heat can work down to -13F, The absolutely best resource I’ve found for heat pump research is the NEEP database which will you give you actual BTU outputs at various ambient temperature readings: https://ashp.neep.org/#!/product_list/
 Also worth considering a geothermal heat pump depending on your geography, as then you have a guarantee of efficiency all year roundSecond the NEEP database. I’d just add that the lowest temps listed here aren’t the actual equipment minimums - each model has a cutoff temp where it will literally shit the bed (except ground source of course). For my mistu hyper heat, it’s -26F. Capacity will keep dropping after -13F though (where it’s still at like 80% I think).

Housing, food, car insurance and alcohol are all pretty expensive in Canada
So…living. Got it.
Cellphone plans, internet plans, seriously look into the cost of living in Canada.
Telecoms have a stranglehold here, our cell phone and internet prices are some of the highest in the world (if not THE highest).
They also own some news and media companies which only makes it harder to bring about change
Wine and cheese, damn it’s expensive compared to Europe!!!
Electricity is also pretty expensive everywhere in Canada other than quebec
Linus (tech tips) said Vancouver BC has cheap electricity bc it’s all hydro.
Yep, BC and Quebec are both hydro
https://elements.visualcapitalist.com/biggest-sources-of-electricity-by-state-and-province/
This seems accurate, but I haven’t verified
May vary by municipality but BC is the 3rd cheapest in Canada
…And it’s like 50-75% more expensive than Quebec
Manitoba has some of the lowest rates in the country
Yeah, it’s the 2nd lowest, but Quebec is still dramatically cheaper
Tim Horton. It’s cheap, but not cheap.
Can you just start saying “America” that way it includes south America and Central America, also?
When the context is involving climate, electricity rates, and money, there is little overlap between all of the Americas. It makes sense to tighten it down to the top half (more similar climates, etc) or bottom half (electricity rates for example). Canada has the wealth and the electricity rates to make heat pumps extremely viable, and for the most part climate too. The USA shares a lot of this. The Central/South Americas do not overlap like this with Canada.
But that wouldn’t be accurate because there are South American countries with even cheaper electricity than here, so it’s only the cheapest in North America.
Also not to be too pedantic but central America isn’t technically a continent, and it all falls under North America anyways.
It depends on the model (and the price), I’m in Québec where we have -30°C (-22F) about every winter, my heatpump is mid-range, and works fine until -20C (-4F) so 95% of the time. It is set to 23C (73F) and it’s between 21-23 everywhere in the house. The electric baseboard are set to 21C (70F) as backup.
So yeah, heat pumps can works great in winter, no problem.
Also as written in the article, with defrosting and variable speed compressors, it is very efficient. Mine is Energy Star compliant, and act as air conditionner in summer.
Makes sense to me that they could theoretically work all the way down to near 0 kelvin, just depends on their efficiency. Just so long as there is heat to be had…
Also, not sure energy star really means much.
They theoretically could, but the coefficient of performance would go below 1 long before you get close to zero Kelvin. That means it would cost more energy to pump the heat than is pumped, so you’d be better off using an electric heater.
Ah yes… that’s a very good point. I’m not about to learn a bunch of chemistry and physics and stuff… but I’d be interested in reading about this theoretical optimization if electricity was free, there was no gravity, friction was 0, etc etc etc.
How is this a myth? Nobody with more than two braincells thinks that heat pump heaters don’t work in the cold.
If we start comparing everything that idiots think to a mythological mystery worthy of note, we’ll be here for an eternity.
This is not a myth but a fact, heat pumps don’t work at extreme cold temperatures.
What temperature exactly depends on the coolant used.The efficiency also degrades at lower temperatures.
This is a random example of first hit I got on a heat pump.
https://heatnow.dk/produkt/altech-sirius-9-varmepumpe/Notice the effect drops dramatically below -20 C°.
But this is a pump sold for the Scandinavian market, therefore it is of course designed to work at low temperatures. It doesn’t state the minimum, but I’m guessing it would be around -40 C°. Which is very good compared top older models.
But that’s not sufficient. As the temperature gets colder, it’s not just less efficient but produces much less heat. At the lower temperatures, it may not be able to keep up. Since it would be wasteful most of the year, heat pumps aren’t sized for that
IDK why you are downvoted, this is exactly true. The pump can only use it’s max power, and at max efficiency it generates 4-5 times that power in heat. But at temperatures below what the coolant allow, it only produce heat equivalent to the power put in, or a 4th to a 5th it’s max output.
Meaning the pump gets less efficient as it gets colder, and potentially will not be able to keep up in extreme conditions. As output goes down at lower temperatures, the same time demand for more heat increases.
The Heat pump shown however, does go very low, and it would be exceptional if the limit was reached. But just a decade ago, most heat pumps couldn’t go nearly that low, and lost efficiency quickly already below zero Celsius.
Despite that, the advantages with the newer heat pumps are still big enough for it to make good sense to switch to it for most, even Scandinavians.
Here in New England as far as I can tell, HVAC contractors tend to recommend hybrid systems, with a gas furnace as the secondary heat. However maybe that’s because gas is much cheaper than electricity.
Maybe there’s a contractor around who can give a better opinion on whether my experience is general
I never heard about that, here it’s very extreme if it’s below -20 C°, and new heat pumps can handle that, and remain pretty efficient.
I think the consensus here is to get rid of the gas. Despite we have it from the Nordsea, but the price structure is 100% dependent on the situation in Europe as a whole.
And Russia has fucked that up. So I don’t think anybody here is recommending gas for that reason. Although gas has already returned to be the cheapest option even here AFAIK, and prices have stabilized in part due to LNG from USA.
The heat pump I just had installed in SW Ontario hands over heating duty at -10C to the gas furnace
How much did it cost and what rebates are available? I’d love to say fuck Enbridge.
$12K for the heat pump and furnace. We’re expecting a $7K rebate (did the replacement before the audit because the old furnace died)
Damn that ain’t cheap. What’s the expected savings per year in reduced gas/hydro?
Edit - how quick is it expected to pay itself off
I’m not sure, likely somewhere between 5-7 years.
We wouldn’t have done it if our furnace wasn’t shot. As a plus our A/C leaked it’s freon in the winter, so replacing it was an improvement as well.
You could have gotten a whole home mini split from senville for less and it works down to -30. My heatpump from 15 years ago only did down to -10.
I found all the HVAC guys in my area were still really pushing the heatpump and furnace combo because that’s what they knew and not what was best, cheapest or most efficient.
How does a mini split system work? Does it plumb into traditional ducting?
Edit: just looked them up. Also found out that a friend out East with an older, oil heater house (no central ducting) was quoted a mini split for their place at over $20K
Our place is a four bedroom, two storey with a basement. I wonder if a mini split with the requisite air handlers would be cheaper
On a side note, we have a West facing room with large windows that I have to run a portable AC and space heater in as it’s temp is always extreme vs the rest of the house. A mini split just for that room would be great
They are honestly pretty easy to install if you are at all handy. The smaller ones (like for a room) have minimal electrical needs and are something you could get an electrician buddy to do for a case of beer if you buy the parts off amazon. Depending on the brand they are varying levels of DIY but nothing a 5 min youtube video can’t teach you. All in for my house it was 6k and a saturday afternoon to get it done.
How many mini split heat pumps and air exchangers did you put into your place
Overall, we should be net $5K with an installer because of rebates, but it’s good to know cheaper alternatives are available
It really depends on the type of heat pump. Air-sourced heat pumps generally don’t produce heat below -30C and below -10C they generally lose enough efficiency that you’re better off using electric baseboard heating.
My air sourced heat pump keeps my house warm just fine in the Finnish winter where temperatures of -30C aren’t unheard of. I’m not exactly sure how it works, but I assume there’s coils that’ll produce the heat by electricity if nececcary, making it at worst as efficient as direct electric heating, which is what I’d use otherwise. Here like every other house has a heatpump like that and I don’t remember hearing anyone ever complaining that they’re not working.
The argument is bullshit in totality. But… When the supplemental electric heating coils come on, it is less efficient ON THAT DAY, than the alternative electric options. But, like I said, in totality, it’s more effective over a month, and certainly better over the course of a year. It’s a matter of people with an agenda cherry picking the 9 days a year in which it is less efficient and pretending that the other 354 days don’t count.
When the supplemental electric heating coils come on, it is less efficient ON THAT DAY, than the alternative electric options.
It depends what you mean by the alternative electric options. Electric resistance heating is 100% efficient and that’s what my heatpump effectively is when it gets cold enough. It’s not less efficient than wall mounted electric radiators even when it drops to -30C. You just lose the efficiency of a heatpump for that time.
Exactly - people somehow fail to understand that Heat Pumps, by necessity, are always more efficient than 100% of an equivalent electric solution.
I suppose if electric heat is the primary option then sure. Around here though natural gas is pretty much ubiquitous and the cost per joule is a heck of a lot lower than electricity. About $6/GJ for natural gas, compared to about $42/GJ for electricity. Would need a pretty efficient heat pump to see the cost savings in my area.
There are heat pumps now that use gas to do the supplemental heat. Those are the best possible option. They are equally efficient to a gas furnace when supplementing, and even cheaper when not.
I’m sure there’s applications where that’s true, but then you’re essentially talking about having a gas furnace plus a heat pump, so you’re installation cost is close to the sum of both systems. Energy rates vary by region, but around here electricity is about 7 times the cost of gas, so a heat pump running at a coefficient of performance around 3 would still cost twice as much to run as a natural gas furnace, it would be cheaper to just turn off the heat pump altogether and only use that “supplementary” heat.
When I was looking at new heat pumps the hybrid ones were between 500 & 1000 more than the equivalent electric ones.
It’s not a sperate unit, it just has a gas heater in place of the electric supplemental coils.
I think mine is undersized and close to 20 years old now. Reading your response is yet another reason I have to go through with upgrading everything.
Generally you’d have a backup heat source with an air-to-air heat pump for those really cold days like -15C and colder, like a gas furnace or a heating element unit inside (like with electrical coils). Air-to-air heat pumps are more efficient on warmer days, on colder days they would be less efficient but you’d still have a backup heat source so it would still “work”, so the article is still somewhat correct in that sense.
Also, electric baseboard heaters can be quite a bit louder than forced-air systems with a heat pump, so you’d still be better off with a heat pump in those cases.
Same with EVs. Don’t work in cold weather. Except in the Nordics.
EVs work fine in cold weather. I live in Minnesota and drive an EV. It loses about 10-20% of the total range in the winter, but most of that appears to be from generating heat for the passengers.
I was being sarcastic. I’m from Germany and most “car people” constantly talk about EVs being not reliable, especially during winter …
Ah yes, that time of year when cars are known to just start right up every time they’re cranked over, and gas cars totally aren’t still subject to a battery getting cold …
Gas cars don’t have a battery, they run on… gas
.
/s
In their defense, my German EV lost a good 40% range on the winter
That’s really bad. What brand/model?
VW ID3
Ah. The liar-company.
Yep… did not get to choose which car I got, and was quite disappointed with it. The car itself is okay, the driving is good. But the battery and its management was horrible. They even sent a recall recently because the battery was draining abnormally fast when not using the car
The problem isn’t that EVs don’t work in the winter, it’s that their range gets significantly reduced. We had issues with people literally up and abandoning their vehicles because their batteries ran flat.
In these cases the issue is less that the range is lost, and more that with snowy and cold weather traffic gets unpredictable. You can end up in long queues and that’s where the issues start.
When I went on a work trip up in the far north I never saw a single EV. Asked my colleagues about it and none of them thought EVs particularly feasible as a primary vehicle.
All that said, EVs work great for most people most of the time.
It’s not so much a myth as it is old information that is no longer accurate
The heat pumps that were available 20-30 years ago weren’t effective/efficienct enough at low outdoor temperatures to be practical.
Was it necessary to kill birds th?
Yes. Goddamn dinosaurs biding their time until we kill ourselves off, just to build a new golden age of dinosaurs
I mean, it’s not about them not working, it’s the efficiency. Most models will switch to a normal electric heater, if they can’t extract anymore heat from the surroundings. At which temperature that happens, depends on your type of heat pump.
Not correct for modern heat pumps. They work down to at least -40F without switching to creating heat.
That’s why I said it depends on the type of the heat pump. Some can go really low, the cheaper ones not. At some point (the latest at -273.15C :D) they need to switch.
The overwhelming majority of even high end cold climate ASHPs do not function at -40 C/F. -20F, that’s doable.
I want to understand what happens when it’s too cold out. And just running in pure air sourced HP mode, without supplemental heat.
Does it keep running at 100% but produces no heat? Limited heat? Does the house get colder and colder until everyone turns into a popsicle?
Or does it only heat the house to 18c instead of 20c?
In a climate where the low is -10c, how well does it work?
I can only talk for myself but I have a Nibe pump here in Sweden with air source outside pump and water heating system to radiators on the inside. Even down to -30° with really shitty windows it was enough heat for me to be comfortable. Though it did indeed use the supplementary resistive heating a bit it was still able to give me about a 200% efficiency during that period. Give a typical winter (usually around -5-10C but, as said can go down to -20C or -30C for a week or so) it still runs an average of about 300-400% efficiency.
I have an air sourced heat pump and it gets to -35C for a few weeks at time here. When it’s that cold it does produce heat but your breath is hotter. There’s no point in running it as it just doesn’t make any kind of useful heat. Below -10C the amount of heat it produces noticeably tapers off.
One thing that happens is that the defrost cycle takes a longer time, so it spends less time heating the building
So my question with heat pumps is more how much does humidity effect the efficiency? Where I live is high elevation, has cold winters, but the air is dry as fuck. Single digit humidity for a month wouldn’t be unusual.
My understanding is that heat pumps work best with humidity since moving moisture is part of how the heat is produced. When does a reasonably priced heat pump start falling off in efficiency?
No that’s just my shitty heat pump. Sigh…
There is a really, really big caveat here.
While all of this is true, and while heat pumps are definitely more efficient than gas/oil/electric heat, you MUST have a well-insulated home without drafts. If your home is not well insulated, or is drafty, then heat pumps likely will not keep your home at a comfortable temperature.
A standard furnace works by kicking on when heat drops below the set point of your thermostat, and then it blasts heated air until the whole space is a certain temperature above the set point on your thermostat, and then shuts off. The most efficient heat pumps are constantly trickling a little heat at a time, rather than cycling on and off. If your home is poorly insulated or drafty, then you can end up losing heat faster than the heat pump can bring it in. The better your insulation and the better sealed your home is, the better your results with a heat pump will be.
Unfortunately, my home is largely uninsulated and pretty drafty; without doing a pretty significant amount of work, at a fairly steep cost, I can’t retrofit to a heat pump.
This is my first comment, but since it’s my job might as well:
The fact that you need a well insulated house for a heat pump is absolutely not true. What you need is a house where the expected heat loss at the design temperature can be added to the house using low temperature heating such as in floor heating. You can live in a cardboard box for all intends and purposes, if you can keep your house warm with (loads of) 35-40C water you are fine. And you would be amazed how much heat in floor heating can provide when having tubes at 10cm heart to heart distance from each other. Your energy bill will be enormous, but it would be as well if you would burn gas in a stove.
Does insulation help? Obviously. The most energy efficient, sustainable and comfortable kWh of heat is the one you don’t need. Is it a requirement? Absolutely not.
Source, ex aerospace engineer that advices and installs heat pumps for residential buildings
Edit: This might differ across the pond but in the Netherlands in floor heating is super common. In America I believe this is not so much the case? Not sure.
A standard furnace works by kicking on when heat drops below the set point
So does a heat pump, and you can get Air to Water heat pumps that work almost exactly as a furnace.
The most efficient heat pumps are constantly trickling a little heat at a time, rather than cycling on and off.
Our stoker wood pellet furnace does the same if possible, it can’t go below 25% capacity, because it doesn’t burn right at lower capacities. So at certain temperatures, it maintains a steady state, but at others it has to turn on and off. A heat pump can easily do whatever is more efficient.
PS:
Heat pumps are similar technology to fridges, which also turn on and off depending on needs.
what does insulation have to do with heat pumps?
heat energy is heat energy, where you get it from doesn’t matter, if your house isn’t well insulated the heat loss will be the same regardless what pumps in the heat.

I bought into the heat pump hype until I bought a house with a furnace. Up until then I lived in apartments with heat pumps. I was stunned about how much better it was than any place I’ve lived before. It was used for it taking forever to get warm and always feeling colder than the thermostat would indicate. With a furnace it got warm quick, and it truly felt warm once it reached temperature. My power+heat bill was significantly lower per sqft than my power bill in my apartment.
I’ve lived in the Midwest, the Mountain West, and the South. I experienced the shortcomings of heat pumps in every place.
This article, which I believe to be geared at convincing US readers that heat pumps are great, also does some things that are extremely disingenuous.
For one, most heat pumps in Norway are geothermal heat pumps. Those are extremely different units that are well known to both be more energy efficient and function at much lower temperatures than air source heat pumps that are typically pushed in the US. The example where they interview a guy with an air source heat pump seems like an almost intentional misdirection.
Second, the author uses a comparison to electric furnaces. That has been widely known for years to be hilariously inefficient. As such it’s fairly rare to see in the US. The most common sources of heat in the US are air source heat pumps (in places like AZ and Texas), oil radiators, and gas furnaces. Depending on energy prices, these could be significantly cheaper depending on utility cost. I understand Norway has specific conditions that make oil and gas usage much less appealing but, again, this article is clearly targeted towards westerners.
I feel like this is EVs all over again. Heat pumps have a lot of potential. They will one day before the de facto standard almost everywhere. However they have serious shortcomings and the idea that they are ready to be a drop in replacement in the vast majority of cases is hopium.
EDIT: Since everyone is getting caught up over the word “efficient”. Electric furnaces are hilariously expensive.
comparison to electric furnaces. That has been widely known for years to be hilariously inefficient.
By this, I’m thinking you mean “electric resistance heating” - i.e an electric heater.
Electric resistance heat is 100% efficient. Heat pumps can easily be 200%+ efficient.
For those reading wondering if this guy knows what he’s talking about, he says that electric furnaces are “hilariously inefficient”. They were in fact the most efficient option before heat pumps - more efficient than the most efficient gas furnaces. Electricity is expensive, so depending on the situation, it may cost more than inefficiently burning super cheap gas, but calling electric heating “hilariously inefficient” demonstrates a severe lack of knowledge of the area. So, with that in mind, consider whether anything else claimed here is worth retaining.
I think it’s just a matter of what you’re comparing.
Heat pumps are ridiculously “efficient” in terms of operation (like 200% efficient, etc. etc. etc.)
But from what I am seeing with them they are claiming efficiency as “is it smarter to run an electric heat pump vs. a gas furnace” for your money. In that sense, a heat pump can be super efficient but still not as “efficient” for your wallet compared to a gas furnace given how much cheaper gas is (in the states that is.) Someone else commented that even after all the rebates and everything else, it would take >20 years to reach a payoff in terms of buying a heat pump vs a standard gas furnace. That timeline is generally outside what a typical homeowner looks at here.
I mean- you even acknowledge you pick up what they’re saying so…?
Perhaps we should set new terms like “operational efficiency” which is for the most part indisputable and “monetary efficiency” which is fluid and can definitely be varied around a single country, let alone the globe.
They know exactly what I mean. They are arguing semantics so they can dance around the fact that Heat Pumps aren’t nearly as cost efficient as billed in most parts of the US.
You can argue that the savings are achieved by both not requiring a separate heating device and not having to construct a home to handle gas/oil.
However then you get into the heating issue. Most models just can’t handle any sort of truly cold temperatures. Models that can are often more expensive than a gas furnace and AC unit combined.
There is a way around this: dual source heat pumps. Basically they are heat pumps with a gas furnace that kicks in if it’s too cold outside. They work, and have been adopted in states like Maine, albeit with subsidies. However they aren’t encouraged by traditional media sources because at the end of the day they still use gas.
Again, I feel like we’ve been through this with EVs. There was a narrative widespread adoption was around the corner. That once you hit seven percent you’d have runaway adoption. That by 2030 the vast majority of cars will be all electric. However at the end of the day demand slowed. While EVs worked in some places, there were huge issues (price, range, and charger availability) that prevented wider adoption. The experts were surprised because they were wealthy urbanites who didn’t experience those flaws firsthand.
EVs are the future. Heat Pumps are the future. All I’m saying is that things that are billed as around the corner often take longer than you’d expect.
Honestly I feel like I’m just older than everyone else in this thread. I feel like anyone 30 or above has seen things like this play out multiple times.
It(electric furnaces) may not be as efficient in terms of how much money you have to spend to keep your house warm, and obviously this is the efficiency most people will care about because we are not Jeff Bezos with his deep pockets
Fine. Electric Furnaces are hilariously expensive. Happy?
Compared to gas? Nope. They are not hilariously expensive. Gas furnaces cost more to purchase, install and maintain than electric, and they have a shorter life span. For some people, especially those with minimal heating needs, electric furnaces are most cost effective than gas ones. Again, more basic info you are unaware of.
Compared to heat pumps? Maybe. Ground source heat pumps have huge installation costs and although they are far more efficient it may not make up the cost for everyone. Air source heat pumps aren’t much more expensive than traditional options, but they’re much more efficient. If you’re in an area where an air source heat pump is an option, almost certainly it’s more cost effective.
None of this is what you’re saying though, that heat pumps are unproven, unready technology, which is bunk. They’re not an option for everyone, no option is, and they may not be the right option for you. However, they are an option for most people. If anyone is looking to replace a furnace they should absolutely consider an air source heat pump, and potentially should consider a ground source one.
Okay before I go further I need to ask the following questions:
- How old are you?
- What type of home do you live in?
- Do you own your home?
- What types of heating units have you lived with?
- Where are you located?
I don’t want to waste my time breaking down how wrong you are if you’re a 19 year old posting this from a college dorm.
You have this wrong. The problem isn’t the age of other people on the Internet. It’s that you don’t understand that anecdote and limited knowledge are not a basis for judging the feasibility of a technology or making conclusions about what’s useful for broad swathes of people.
Sure.
