We did not have a thermostat on our system. We bought the house just over a year ago and just relied on the boiler running when we were home.
Problem is that it would never switch off and I suspected that in the milder winter months it was costing a fortune.
However, our main living area needed 6000BTUs but the rads only output a combined 3000!
Last Sunday I upped this by replacing one of the rads with a much bigger double sided twin convector to a combined 7000 and we have also installed Nest Thermostat (couldn't resist a gadget for it!)
It still costs a lot to run and keep warm all day. We had Smart Meters install and you can see that it can cost over £6 a day (weekends) when it is really cold but I don't have enough data to establish whether this is consistent.
I am already geeky/sad enough with an overly complex spreadsheet with all the values.
As we get to the warmer days at least the boiler will know when to shut off and stop wasting gas!
Anyway, in answer to your question, 19C.
