Thermostats and Control heating

Get a digital wireless room stat with programmer, probably the best bit of kit I ever bought.
They even allow you to offset your temp, as my hall is 2 degrees lower than the rest of the house I offset it by 2 degrees, so it shows 18 degrees on the screen but it is infact 16degrees in the hall but 18 in the lounge.

I used this function for the first time at the weekend as the hall is colder than the rest of the house and I'm not particularly bothered about what the temp is in there.

Hi everyone,

Found this thread really useful as i'm clueless about boilers (my first house with gas) so i'm after some help, although its prob been covered but i'm having a blonde day lol.
I dont have a wall thermostat, just the valves on the radiators and the temp on the boiler. The water temp is on the boiler also.
Do i need to set the water and heating temp about the same and have the rads at a mid setting?

Need to get this sorted as currently can't afford to run them through the night, done it once and it chewed £10 in under 24 hours :eek: and it's just too cold in the mornings now :rolleyes:

If it is a combi boiler then you can usually set the water on the boiler for whatever you feel comfortable with (you don't want to scald yourself), and the radiators to very hot if you want a quick warm up. If you have any children to consider you would probably set them a little cooler so there is no danger of burning a child.

The TRVs you will need to try out, maybe just above midway in the lounge and bathroom, a bit less elsewhere.

You should have a time clock on your boiler, most have a basic one, maybe behind a flap if it is not visible. You can fit a separate more flexible one if you feel the need. These can time each day differently rather than the same every day type that are often on the boiler. If there isn't one at all then you need to get one ASAP. They cost about £25-30 to buy. You want a 24/7 type for max flexibility. Then you can set it up to come on first thing, go off when you are out, come on before you get home, and go off at bedtime. No more wasted gas that way.

I heard an energy saving tip which may or may not work, but seems logical:
Have your boiler heat the water when it is already being used to heat the rads.
ie, if your central heating comes on from 06:00-07:00 in the morning, then have your water heating come on during that time, eg 06:30 - 07:00.

This way (so it goes) the gas needed 'on top' of the CH usage is smaller than if you heat the water independently.

Also, check how long you need the water heating on for, to get a tank full of hot.
I only need 15 mins in the morning and 5 mins in the afternoon to keep me and the missus in hot water all day.

PS, my boiler is set to 50 degrees as well.

I also did some sums and found out it costs me 1p per minute to run my central heating, but 1p for 5 mins to run the gas fire in my living room. This means I can run the living room gas fire for 5 hours and use the same amount of gas as my central heating takes in 1 hour.

Hi thanks for tip, my water is set similar to you, but will check ifset arond the ch time. The cost , was this like for like and what temperature, probabaly best to show over 1 hour?

I timed the central heating for 1 hour and took meter readings before and after.
I did the same with my living room gas fire.
I then converted the cubic meters used to kWh's and multiplied by 3.8p which is my annualised gas rate based on last years consumption and this years tariff.

The central heating temp is regulated by thermostatic valves - I don't have a wall thermostat, so can't really say what temp it was all set to - they're all different on each rad but the house gets to 20 / 21 approx.
The living room fire was set to low, which is enough to keep a 16 x 15 room at approx 20 / 21 degrees.

With the temp now improved at around 9C in evening outside. I have notice 5hat the CH radiators take longer to get warmer (When compared to last week when -5), even when the thermostat is turned to 25?

Was is this?

The setting on the room thermostat has no effect on the temperature of the water in the radiators.

Could it be that the heating of the Hot water in the tank was taking priority?

Does the thermostat on the hot water tank , Set to 60C, have any impact on the boiler. How does the thermostat on the hot water tank work?

(Note HW is warmed by Gas boiler not electric)
