OK folks, long story and looking for some expert advice as my Central heating is driving me crazy
I have read several posts on the forum but none so far have answered by concern.
My house is 9 years old, boiler, tank and radiators all in very good condition. The house has three storeys with 2 large bedrooms in the roof space.
The whole house has generally been difficult to heat even with TRVs fully open with the top 2 bedrooms in particular very cold which I had put down to poor insulation (which has been remedied with additional loft and wall insulation) and the fact that each only has 1 smallish radiator positioned in the dorma window recess (not ideal). I keep the pressure in the expansion tank at around 1.8 bar therefore therefor I think there is enough pressure in the system to send hot water to the top storey.
I have toyed with the idea of installing either an additional radiator in each bedroom or replacing the existing radiators with larger ones positioned better in the room.
I believe the radiators are balanced.
That said, recently I have come to the conclusion that even with new, bigger radiators, the real issue is that the central heating is simply not sating on long enough for the radiators throughout the house to get to a reasonable temperature!
My current set up is I have:-
• A Potterton Suprima 60L Boiler
• A Honeywell Electronic Programmable Thermostat in the ground hallway usually set for 21C when programmed to switch on
• Every radiator in the house has a TRV with exception of the radiator in the hallway near the Thermostat (maybe not ideal)
With the help of some kind, expert souls in this forum, I learned that the likely reason that the Central Heating does not stay on long enough is that the boiler is switching off when the hallway reaches the 21C set by the thermostat and of course the rest of the house does not get a chance to heat up adequately.
I decided to take advice from the forum and set the Thermostat very high (30C) and set each TRV to mid-point. The result ... each room became tasty very quickly and I modified each TRV until each room was comfortable. So far so good!
Here is the problem, my ground floor hallway is stifling (24C+) because the radiator does not have a TRV and is obviously still getting fed hot water because the Thermostat hasn’t switched off the boiler.
I even went so far as to fully close the lockshields on the hall radiator to switch it off completely but after a while a Red Warning Light Flashed on the Potterton Boiler which I suspect must be due to me restricting the flow (?)
Any suggestions? I have thought about having a TRV installed on the Hallway radiator so that I can regulate the heat there easier or do I have to have at least one radiator without a TRV?
