Heating Question - Am I right in thinking...

[nikkylou]

Kinda inspired by the other thread. Slightly different issue.

Bit of background: In my house the boiler and the thermostat are upstairs meaning upstairs gets super cosy but downstairs hasn't really had chance to warm up, especially the already cold conservatory.

We're getting the energy company to fit a smart thermostat (like the hive/nest, but ours is going to be a honeywell one) which I wanted anyway.

Anyway:
I'm planning on having the thermostat bit downstairs so the boiler keeps heating until downstairs is warm. But upstairs is going to be hotter than I'd like. If I put thermostats on the upstairs radiators would they turn off the radiators in that room and still let downstairs be heated?

Basically I've never had experience of a thermostat actually working and just had the boiler on timed functions. Plus the only thermostat on a radiator at the moment is in the conversatory, which really never hits the temperature to turn itself off anyway.

Tldr: basically if I have the main thermostat downstairs and individual thermostats on radiators upstairs will the house be a more even temperature all round?

Can you not turn the radiators to low upstairs and on higher downstairs?

When we moved into this house I had thermostatic valves put on all the radiators. The thermostat is in the most critical room and I adjust the rest of the house (room by room) accordingly.

Yes, I think your plan will work OP.

I moved our Nest upstairs as it was always cold in the bedrooms, turned down the valves downstairs - now we have a cosy house throughout.

Thank you all!

I don't think turning upstairs up and down stairs down will help, as it would would still mean upstairs is hotter than downstairs. I'm a little fussy, I dislike it being too hot as well.

I plan to put it in the living room as its the coldest room that's most used.

I think a little trial and error but as long as the theory is alright I won't waste putting thermostats on unnecessarily.

Wrong way around OP! Read the suggestion again.

We have a Honeywell portable thermostat so you take it into the room that matters. Tho' also have a couple of nests and a random towel rails thermostat control too (vendor really liked thermostats...) . Would that work for you? Also we have switched off radiators which we don't need (eg in hallway)

Honeywell also sell smart radiator valves so that you can control the temperature of each room individually.

Yes you can have smart radiator valves
