Multi Point Electric Instant Water Heater

[wozzlegummich]

Looking at fitting an instantaneous electric water heater to supply two showers at same time. I want to fit outside of bathroom and adjust water temp by mixing hot/cold water.

Can anyone recommend a make &/or model?

I can recommend this one:

 

DDC 8 EC (STE) Compact instantaneous water heater of STIEBEL ELTRON (stiebel-eltron.co.th)

 

I use it and it works fine.

It has only one water output. I bought an adapter to divide it to my kitchen and bathroom.

Funnily enough, that is the one that had already drawn my attention. Just wanted a few other ideas in case I missed the best one.

Am sure people have better luck than me but I have never had good luck with such units installed in hospitals or hotels - scalding hot more often than not as most places do not have cold enough water to mix it with.  Understand units can be adjusted a bit but this does not appear to be the norm here (or too lazy to adjust several times a year as water temps change).  Find local hot shower only much more to my liking.

It seems the heaters which are designated as shower heaters are supposed to have a constant temperature.

 

I use the heater which I mentioned above for my kitchen sink and my bathroom bathtub and shower.

In the kitchen I have an ordinary mixer of hot and cold water. If I put it to max hot the water is very hot - just about possible to touch but I wouldn't leave my hand under the flowing hot water.

 

In the bathroom I use a faucet with a thermostat. At least the one I use, from TOTO, works perfect.

That may well be the issue - as suspect most do not install more than basic taps.

And thermostats fail after a while.

We have an immersion heater that heats water for the bathrooms, spare bedrooms and kitchen. And use faucets like this. If you but quality they will last years and years in a hard water area if you also use a softener.
