Cheapest way to use gas central heating

If you decide to move your thermostat to the living room, bare in mind:

- you must turn the TRVs on the radiators in the living room to max, otherwise they may cut off before the thermostat has reached its temperature - the result being the thermostat is calling for more heat, but never gets it as the radiators are off = boiler running endlessly.

- your living room might be comfortable, but other rooms may never reach full temp before the thermostat turns off the boiler. In a good system, the radiators should be sized and balanced to the room - so all rooms should heat up at the same rate.

Thank you. Going on the same principle...
If I keep the thermostat in the hall where it is now, should I turn the hall TVR to high?

At the moment the thermostat is in the hall (round the corner from the hall radiator--L shaped hall) and on the short wall opposite the internal door to the kitchen.

Another radiator is situated just inside the kitchen door. If I leave the thermostat in the hall, should I turn the TRVs in the hall and kitchen to max?

Yes you need to keep the radiator closest to the room stat on full (the radiator supposed to be in the hall too not in another room...around the corner without doors in the way should be ok) so that when all the other radiators have shut off then the heat being generated by the boiler is being output by this one radiator and eventually the hall will get to 18 degrees and shut off the boiler.

It's also the quickest room to lose heat due to the front door so it should come on before the other rooms have cooled down too much.

Thank you. The kitchen radiator is nearest to the themostat, but the kitchen door will be kept closed (because of heat being lost when back door is opened.) Do I need the kitchen TRV on high as well as the one on the hall radiator? (that radiator is situated round the corner from the thermostat)

It suddenly occurred to me that neither of my living rooms are joined to the semi next door --only the halls are next to each other--so there is a long bit of outside wall in each living room which might make them colder than the hall?

But then again with the front and back door being opened and closed throughout the day the hall will probably be colder than either of those 2 rooms

With a fixed wall thermostat there is always a dilemma.

If it is in the hall - which is often the coldest part of the property - then the temperature of that hall controls the central heating for the whole house.

Put it in a living room and when that room is up to the set temperature, there is no central heating to other parts of the house.

My thermostat is in a large hall with a wide staircase leading off. I really don't want to heat that hall at all, as we only walk through it to get to other rooms or go upstairs. So if I heat the hall to a low set temperature, when someone wants to use another room/bedroom(where the radiators have been off) the only way to get heat is to turn up the hall thermostat.

You shouldn't have both a TRV and a room 'stat in the same zone. If you do, open it fully.

Thank you. The hall radiator is about 1 ft round the corner from the thermostat and about 6 feet away so that's in the same zone. The kitchen radiator is about 6 feet away too in the opposite direction but the kitchen door will be kept closed most of the time. Should I have the TVR on that radiator turned up to full too?

If the door is shut then it's a different zone. Who installed a room 'stat along with a TRV next to it though?

Personally I find it is better to have it on a timer and then to take advantage of thermostats in different rooms. It only takes 15 mins (prob less) to warm my flat. You can have rooms at different temperatures e.g. bedrooms cooler. Heat rises so take advantage of the fact. Also does your kitchen rad need to be on full if you get warmth from the cooker?

The heating engineers installed the radiators and TVRs then their electrician came along to put up the thermostat. It's not really next to the TVR though but on the hall wall opposite the internal kitchen door and slightly to the side. Radiator is just inside kitchen door (so when door is closed that will make it a differnet zone)

I hardly ever use the cooker. One cooker ring and a steamer for 15 mins once a day (plus microwave)
