Get thermostat fitted

abbas5001

Hi all

Need some advice from someone who knows a thing or two about boilers. I want to get a thermostat fitted for our boiler and placed in our hall as we don't currently have one. The boiler is a vokera linea.

Spoke to a plumber and says he will order the thermostat for me but it will need an electrician to install it - it runs on radio signals apparently.

He was saying he'll order the thermostat for me and it will cost approx £150. Seems a bit steep, how do I know what is the right thermostat and I can maybe check a price myself

Aftermarket wireless thermostats are pretty generic and aren't boiler specific, although most boiler manufacturers do sell their own thermostats. Check out ebay or amazon, programmable wireless 'stats can be had for around £40 - £50.
As for needing an electrician to install it . . . . Hmmmmm, debateable! :-/

I bought a wireless one recommended in a thread on this forum for about £40 from Plumb center, their own brand, and fitted it myself although I do have some electrical experience I am not an electrician. I found the drawings for the Vokera on the internet

Are you sure you need one? I've had a wireless thermostat fitted to my system by a heating engineer who is also an electrician and to be honest, I'm not sure I needed it.
The house is fitted with TRVs and they seem to work really well. They turn off the flow to each radiator when it reaches the temperature you want. Turning the system off when the temperature reaches a certain point in one room only can leave other rooms cold.

The trouble with only having TRVs is that the boiler will still run. A boiler itself does consume a non-trivial amount of electricity, and then there's the inefficiencies of the boiler brought about by short cycling as the TRVs are not open...

The other problem with TRVs is that most aren't time sensitive, and people tend to use different rooms at different times of day.

I woz going to write what Smiley Dan wrote, but he beat me to it.

A well tuned and balanced system should keep the area where you're spending most of your time warm when you want it based on the settings on your thermostat. Your unoccupied rooms should stay cooler than your living area thanks to the low setting on your TRV's and any rooms that are occupied should be as warm as your living area because of the high setting on the TRV's.

I find it's impossible to balance the heating in that way. Rooms at the front of my house get sun, so can get very warm whilst at the same time rooms at the back don't get sun, so can still be cold. If you have a thermostat in your front room the system will turn off and the other rooms will stay cold. If you use the TRVs only the rooms will all individually increase in temperature.

Interested in this. Will the Vokera Linea 24/28 work with wireless thermostats bring such an old boiler?
BTW, OP, how are you finding your Linea? Mine is playing up, probably terminally. Just managed to get it working thru a Vokera specialist....
