My current system uses a combi boiler with TRVs fitted to all radiators except one. As the boiler is outside in the garage I have a 7 day programmable timer in the house. The old room stat which was in the hall area is not in use now.
I am considering a programmable room thermsostat. The central heating engineer I talked to about replacing a single radiator with a double radiator didn't see the point in fitting one as the TRVs should control the heat in each room but did say he'd get some prices from wireless programmable thermostats if I really wanted one. I suspect as a plumber he's not really into the electrical side of it. Perhaps it's really an electrician that's needed?
I could see the benefit, especially at spring/autumn where the timer often brings on the boiler where I don't feel it is really necessary - TRVs eventually cut off the heat but there are times the room temp is high enough to keep it off anyway.
I've looked at the Honeywell CM927 which seems ideal. I assume you would put the room unit in the main living room? My current programmer is a Drayton Lifestyle LP711.
Can anyone advise if getting a programmable thermostat is a good way to go? Is the CM927 a good choice?
I'm not electrically minded so would need it installed - would this be an electrician's job rather than a central heating engineer? What happens with the original programmer - does it replace it or work in conjunction with it?
Sorry for all the questions - just want to get it right. Thanks for any help.
