Faucet without mixer? Only hot/cold?

If I wash mine in the evening, they are often still wet in the morning. I don't use a hairdryer ... It takes a few hours of air drying. The civilized Central European who doesn't work in a coal mine or construction site also can't manage to stink after a day without showering. House at 20° air-conditioned, outside mountain climate (significantly cooler), sports in the wind of the air conditioner... The skin also thanks you if you don't have parabens and silicones messing around for a day.

Or to put it with a quote "Two to three showers a week is sufficient," says Prof. Tilo Biedermann, Director of Dermatology and Allergology at Biederstein, Technical University of Munich." Source: Merkur Punkt deh eh.

All day out in a jacket, then to training and soaked in sweat from head to toe, the dear professor can gladly come by and have a sniff.

And I shower cold after sports, with a clear conscience. There's enough water.

why can't they, anyone can set the temperature to half a degree accurately? I don't see the problem right now.

Anyone can set the temperature to half a degree, right?

In the shower or do you have to leave the shower? I, like many people, shower warm first, then cold. Despite all individualism, I think a house should also have a certain universal character. So, if I ever have to sell my house, average consumers should be able to say yes to most things. This includes quite normal hot-cold water connections. Just my two cents ...

As far as I can remember, Elina wanted to save heating costs for the hot water by doing this. Since, for example, 30 liters of water at a temperature of 38 degrees requires a certain amount of energy, whether the water is heated to exactly 38 degrees or mixed from 50 degrees and 10 degrees in the appropriate necessary ratio, there are NO or only marginal savings possibilities if the instantaneous water heater could operate at a slightly better working point with a slightly higher efficiency. Whether that is actually the case would first have to be investigated. Objectively speaking, however, it is an unnecessarily exotic solution that could possibly bring more disadvantages than any advantage. Especially nowadays, there are such great shower fittings. With these, you can easily and very accurately adjust the temperature with one control knob and the water volume with the other. For example, with our HG Ecostat Select this works perfectly with *. The washing machine can run at the same time, someone else can turn on the faucet, and in the second bathroom someone else can flush the toilet; the temperature remains the same, you notice NOTHING! And by that I mean nothing, not even a brief fluctuation that you wouldn’t mind. In addition, it offers a surface for about 8-10 "normal" bottles or tubes of shampoo, shower gel, etc., and you save additional holes or an extra shelf. This sounds like an advertisement now, but we are simply enthusiastic about this thing. In the instantaneous water heater, the water can then be heated to, for example, 2 degrees above the maximum shower temperature, so that only minimal cold water is added and thus the working point, if it is even in the optimal range at all, hardly shifts.

Hi,

... a house should also have a certain universal character.

Then from now on, it's already 4 cents.

Nowadays there are such great shower fittings.

Not only today. We bought our thermostatically controlled fitting over 10 years ago at the grocery discounter (the one with the "A"). Six months ago we had to replace it because the mechanism increasingly failed. The successor is now from Grohe.

Certainly, thermostats for the shower have existed for a long time. We have also had several or, when traveling, been allowed to "test" one or the other in hotels. Often with others, however, the temperature fluctuated (much) more or less when turning on the faucet at the sink or when the washing machine was running. With this one, as mentioned, you don’t feel anything at all, which makes the exotic solution absolutely unnecessary. Additionally, as mentioned, there is a nice generous shelf. To save something, I would rather buy a tankless water heater that does not shut off or stutter even at low flow rates. Then one could mix easily or also reduce the water flow significantly, which certainly saves more than a possibly minimal shift in the operating point costs. BTW, if the OP really wants to stick to the solution, maybe she could look around the American market. There, I believe it is common for the fixture to have only one knob, with which the water (cold) is first regulated from zero flow to 100% flow, and when turned further at a constant 100% flow, the temperature is regulated from cold to increasingly warm.
