In 2004, my local gas engineer fitted a Chaffoteaux & Maury Combi Boiler in my parkhome (20' x 25' twin unit size) as a replacement for my old Baxi back-boiler. At the same time, he fitted TRVs to all (6) radiators, except for the one in the bathroom, and disconnected the Room Thermostat claiming that the heating could be controlled using the Boiler switches and setting the TRVs.
However, when the heating is on, the boiler seems to be forever 'cycling' whether I have the heating on high or low and this does appear to be an inefficient - and expensive - use of gas. Subsequent annual checks by an assortment of gas engineers from a local Heating Engineers do confirm that, at the time of fitting, a Room Thermostat was not essential and the best way to get my TRVs working efficiently is to turn the Boiler Heating control fully on and then set the TRVs to suit my requirement in each room. This results in a sizzling hot bathroom radiator (remember - no TRV) and still the constant 'cycling' of the Boiler. In my mind, still an unnecessary use of gas.
This does seem to me (just a novice paying the gas bill) an incredible, expensive, inefficient way to operate a gas boiler and so, I return to my Topic Question - should I have a Room Thermostat fitted on my System? If so, where should it best be fitted given that the only radiator without a TRV is in the bathroom?
Thanks in advance for any and all help and assistance.
So sorry to be long-winded but it is the only way I can explain my situation to someone.
