I'm new to the Forum and am about to show my ignorance of central heating systems, but please bear with me.
I recently had my 20 year old boiler replaced with a Vaillant combi boiler.
The central heating system is controlled from a wireless programmable room thermostat situated in my living room. The only radiator I have used since installation of the combi boiler is the one situated in the living room. I keep the doors to the living room closed when the system is in use in order to minimise the firing of the boiler and my gas bill.
Now to the point of this post: If the boiler is only firing in response to the temperature in my living room (with doors shut), what will happen when I put the heating on in the upstairs bedrooms ? Will the boiler have to fire more often to provide hot water to the upstairs radiators even though the wireless thermostat in the living room will only be responding to the temperature set for the living room, therefore increasing my gas bill ? My gut answer is "Of course it will". But is this true?
