Nest Thermostat - Cannot turn Hot water heating off

szaszasz — Sun, 02 Jun 2024 20:57:36 GMT

I have the same problemlike fredu1 (his conversation(topic)).

It is with a Viesmann CombiBoiler.

Was it fixed the problem?

Is there a new update (software)

The hot water constantly get heated (not for heating) even when we are sleeping. The nest keeps the combiboiler to constantly heat the water above 40C. We are not using the water and even midnight the boiler starts (not for heating the room) to heat the water which we dont use it

I can wait for water to come when i have demand on it but when i don't have i don't want to start for heating unneceseraly. (Wasting energy and gas)

I need a fix for this!

I want to have the option on my nest to turn off the hot water heating (unless on demand)

Are you in the UK?

When was the thermostat installed, and by who? ie electrician, Nest Pro, You?

What model do you have?

Have you checked for any software updates or integrity garage contacted the manufacturer for assistance? It's important to optimize energy usage, especially when heating water unnecessarily.

Have you checked to see if Bacteria is disabled. Turn off if enabled.

This is a process of elimination to see if the H/W is causing your issue.

When I have issues I search to find if anyone has had a similar problem!!

What is the hot water temp, have you found anything there that might solve your issue?

Re: Nest Thermostat - Cannot turn Hot water heating off

Just the water temp, for the tap water.

That’s a new one on me! Where you have water temp it’s usually Bacteria! Can you disable that? Perhaps even raise or lower the temperature. That could be the problem if the setting is too high or to low.

Failing that, best idea would be to get the expert back as they installed the system.

I tried but to rise and low the water temperature, but it keeps the water warm

Can that setting be turned off?

Mods the user needs help with this setting, is this normal for a display to have Hot Water Temp instead of bacteria?

NO 😞 and i think that is the problem

I'm familiar with UK thermostats, and to be honest didn't think they were any different from Europe. I don't have that Hot water, we have Bacteria. Let's see if one of the mods can help

I think they are the same, connected via Heat Link.

So... i can't really what's the situation with mine.

Thank you for the answer.

Hope the mods will see soon this post 🙂
