5 pound a day on gas?

droiderm

We have recently had a new boiler installed
We have had a new gas bill covering 40 days.
481 cubic metres or 5452 khw
That's197 inc vat. We used to have a thermostat but it's now controlled by setting the temperature of the water. I assume it just maintains the water at that temperature. So it's a different way of using it
It's timed to come on for about 4 to 5 hours a day but often on for more
I think I need to cut it down. But does it seen reasonable ?

5 pounds a day is 150kWh or so, which is not implausible for heating, being about 7kW average.
The hot water is not going to be a big component of this - the basic way to save money is to reduce the time the heating is turned on, and the temperature it's at.

If you consider that it's goint to be be about this level for another 3 months, that'd be another 600 quid, which is not an unreasonable annual bill at all.

Measures may be possible to take to improve the house - for example, draft sealing.

How big a property do you have and how well is it insulated?

We spend 4-5 pound per day on gas too. I think this is fairly reasonable and about right for our property.

Heating is on 24/7 but specifically heating between 6am and 11pm the stat auto drops overnight.

Consider turning down by 1-2c; you're hot water should be around 57-60c and heating 18c bedrooms and 20c hall. Add 10% if you're perhaps 60 or over.

Turning down the stat whilst maintaining a healthy comfort will probably save the most combine with heating when you need it.

Augmenting with spot heating can be useful.
For example, electric blankets can make a very, very cold room quite inviting, used right, very inexpensively.

No longer having a thermostat is why it is costing so much. The boiler is on constantly at the set times you have it set to be on, instead of switching off when the desired temp is reached.

I think Building regs state that you must have a means of switching the boiler off when the desired temoerature is reached, eg a room stat. They also state that TRV's alone are not sufficient.
Of course this means on any new work including updates.

I think a revisit to your installer is required.

As above, a new install without a room 'stat is a breach of building regs-and also an absurdity. You can't regulate the CH temp via the hot water control!
Make and model of boiler?

Thanks all for the replies.
I created my first post on my phone, so I was a little too brief.

I think I need to be a bit clearer.
We live in a rented 3 bedroom semi. It has cavity wall insulation and insulation in the loft. However the issue is , is an extenstion built on to the kitchen which has a plastic type conservatory roof. That aside (I can get the make and model later) there are two controls on the boiler. One for the temeprature of the hot water that comes out of the taps, and one for temperature of the hot water in the central heating system.

I just assumed that it's similar to having a thermostat. For example, set the CH temp to 40, the boiler will heat the water to above that temp, then as it drops it will kick in again. However, my confusion is how does that compare to setting a thermostat to 19 or whatever. Unfortunately there seems to be no relationship between the temperature in the radiators and the temperature in the room. The CH temp control goes up to 80 or 90 I think.

But it seems like from what's said it seems like there should be a thermostat too?

Not sure how much luck or how long I would wait to get that installed. In the meantime I guess I just have to deal with what I have?

The controls on the boiler simply control the output temp at the boiler to each circuit. They do not regulate the room temp, as the sensor has no idea what temp the rooms are. That's why you are required to have TRV's and a room 'stat.
So you must speak to your installer, as this does not meet Building Regs.
