Then reduce the temperature by 0.5 degrees or so. You'd be surprised the difference 0.5 to 1 degrees can make. I used to have an old analog thermostat and my heating ping ponged from being too hot to too cold. The nest maintains a much more even temperature.

generally they are not knowledgable, nor are the installers very knowledgable.
I have an air to water heat pump with two zones and no hot water/immersion
control and this made the guys who came to our home very nervous.
I had to call, DIAKIN (manufacturer of Heating unit), nest, builder's foreman (who was luckily around). All these calls were worth it as this gave some confidence the Electric Ireland guy.
Now we have a nest thermostat for downstairs and another heatmiser thermostat upstairs. The nest thermostat would not control hot water though, as its always on with Air to water heating.
I'm planning to install another one upstairs soon.

So the general rule of thumb: one nest can only control one zone.
If you have two zones you could assign nest to one of the zones and keep another thermostat for other zone.

Should a NEST be used with heat pumps ? Can’t imagine it’s suitable. Heat pumps have a poor response time and wouldn’t benefit from a Nest.

I have a one zone heating system that has a "summer switch", which cuts heat to the radiators during the summer, so the boiler just heats the water tank. Does anyone have a similar set up and if so, is it possible to use the Nest to set the boiler to come at certain times no matter what the temperature reading, or do I have to redo my schedule and just put all the temperatures way up so it comes on regardless?

I wanted to check about a particular use case with my thermostat to see if it's configured incorrectly, if it's incompatible with what I'm trying, or if I need a plumber.

I have oil heating, and upstairs in my house, I have a hot water tank with an immersion heater in it that I can control using a switch at the tank. When my heating runs, it heats water in the tank, but I was also able to turn on the switch to heat the water in the tank independently if needed, though I don't do this often. I tried to do this yesterday evening, and the immersion heater didn't heat the water. Is this something to do with the Nest? (I just wanted to check if this has somehow been overridden by the Nest before going to the expense of calling out a plumber to look at the immersion)

Nest can work with an immersion, however it needs to be wired up via a relay or contactor to provide the on/off action and this would not be a standard install.

It may be a case that the installer disconnected the immersion to provide power for the heatsink but it would be poor practice.

If the immersion worked prior to Nest install and has not worked since, it's likely an installation error.

If the immersion has worked since the install, and has stopped now.
It is likely an unrelated but coincidental fault.

Got mine installed last week by Electric Ireland.

2x Nest and 2x Google Home for 400euro installed.

Got 200euro credit for switching to Electric Ireland so all in all a good deal.

The nests are the business - I had two old-style thermostats and they just replaced this on the wall. Also got a stand from the installer if I want to move it to a room.

Google Home works great, as does the Nest app.

Now if only this cursed good weather would go away so I can turn on the heating

Where do you see the benefit of the 200euro? Like does it come off the first few months bills or what?
