This type of control is known in industry as “bang-bang control.” Among other factors, it doesn’t help that the delay time between twirling the control and feeling the temperature change is often tens of seconds.
I know this is a joke, but usually it’s caused by old cartridges. If you replace the valve cartridge then it will probably mix better. This is usually from old/bad seals. This is why new valves mix fine, but as the seals age, mixing performance gets worse.
Pulling old cartridges can be a pain in the butt so probably best to call a plumber if you don’t like diy adventures.
My apartment is 1 year old.
Contrast the houses around here which pre-date the Great War and tell me why their water works well and mine is this binary pain.
They have two separate taps, though, but that shouldn’t matter. Right? Right?
Are you new to separate taps? I’m assuming you mean one hot one cold. I turn on hot halfway then turn on cold like a quarter of that. Then mess with the cold only from there Hope that helps!
Joke aside, get a thermostatic mixer. It can even save you water and money by instantly getting the right temperature water instead of standing outside naked for minutes juggling with a settings, while the water is on.
Is there such a thing like a thermostatic mixer with “two profiles” (one for me and one for my wife)?
Most thermostatic (non-digital) mixers can be calibrated to a single “default” temperature, but you still have the option to increase/decrease.
I have experience mostly with europen models, where the default is usually around 38-40 celsius, but you can still adjust it about +/- 6-8 degrees.
There are some fancy digital showers with multiple user profiles, but I personally would never buy anything electronic in the shower. It never lasts in my experience.
My current shower is like this, especially in winter.
Water as cold as a nebula
tweaks hot faucet a millimetre clockwise
SATAN’S PISS!!!
I’ve often wondered if this is something that could be engineered correctly or is it genuinely a difficult problem to solve with multiple variables (incoming water temps, pressure, etc)
A thermostatic mixer is the usual solution. Set your desired temperature and the valve dynamically adjusts the hot and cold flows to produce that output regardless of input temperatures and presures.
Works great until it jams at the “instantly vaporize target” setting. Which reminds me, I must call a plumber…
I’ve never had this problem anywhere I live (Sweden and Japan) so I’m assuming it has to do with some kind of especially cheap fixtures?
There wasn’t a very limited range on the dial in which a human would feel comfortable?
This is the dial in our current late-90’s apartment (apologies for the limescale). It is gradated in Celsius
My kids like something in the mid-30’s, I like just under 40, my wife like closer to 45. A pretty decent range IMHO
Was thinking on this tonight! There should be a mechanical solution. No electronics or other complications to fuck up down the road.
We’re all different with comfort levels, hot water temps, flow rates, all that. We need something with sliding or rotating valves that lets us dial in a range we’re comfortable with.
Set X as the lowest temp and Y as the highest. Now when you get in the shower you can spin the dial, all the way around, yet remain in your personal presets.
Better graph title: Shower water temperature by position of knob
The difference between absolute zero and the Planck temperature is less than a Planck length.
That graph is getting dangerously close to becoming a political meme, given current events
Isn’t it the other way around?
Curious, don’t most people dislike graphs? It may remind them of math.
EDIT: Why is this downvoted?
They remind them of the only part of math they liked
