Leave it on or not?

[Doodlebug]

I get a lot of customers asking is it more economical to leave the heating on all the time and just control with the thermostat or is it best to use the timer. I personally think its best to use the timer but is there any real answer to this?

Depends. On a modern modulating boiler i say leave it on as long as there's a room stat and trv's

Depending on the time between on & off on the timer. It's like re-filling your kettle all the time with cold water & re-boiling. It's going to use more energy so i'd agree with the above. Leave it on & control with a Stat & TRV's

Most people I know just use the stat ! makes you wounder why we bother fitting time controls ! most people dont use them.

Ensure the stat on the boiler is at max and let the room stat control the on/off. That's according to Honeywell who also state that a room stat will save around £10 a month on gas.

Although there is some merit in Kay-jay's post for the next generation of systems, the principal is sound it is alway's better to turn things off & reheat as required.
This works because of the way heat is lost, heat is transferred from hot to cold & the rate of loss varies depending on the temperature difference between the surfaces, in this case inside the building & outside, as the temp on the inside cools the rate of loss slows. So less heat energy is lost for a given time. THis works for house or hot water cylinders so the myth is dispelled turning it off when not required is always better than leaving it on, energy wise.
Hope this helps

A lot of views on this but still no definite answer to this. I'm not sure I agree with tuning the boiler stat to max, always thought it best to have about midway.

You can set the stat to what ever you design the system to work out.
As far as a definite answer is concerned science does not lie, unless anybody can prove otherwise ???

My heating stays off and remains off until I feel it's getting into winter and then it goes on the timer and is on from 7am till 8am at 20 degrees and off at 14 degrees from 8am till 6pm unless the wife or kids override it lol. Through the night it's off at 7degrees from 11pm till 7am. So in short if the temp drops enough then it comes on, if not then it don't. Would you say this is an economical way of running it?

Yes, it doesn't matter if the wife & kids are cold until you get in at 6PM. LOL

Over night, even on the coldest nights hold often did the heating come on at 7 degC ??
even set at 15 it is normally off unless it is very very cold outside.

My heating never once came on in the night, my house is very well insulated. I've recently installed remote heating controls where I can turn my boiler on and off using an iPhone, iPod, iPad, any smart phone or a computer, it's great for checking if the wife's put the heating on. Lol

You got a link for the controls doodlebug?

Well worth the investment then, must get it in my house.

What Kit are you usiing for that? Quite like the sound of that.

It's British Gas. Here's the link....

Here's mine....



We are charging £199 for installation and set up for this, ongoing support is free. If I'm on site at a customers house then I'm allowed to charge £150 which I think is a giveaway as most wireless systems cost more than that. The reasons we charge £150 if onsite is because there is no need to send an engineer out. So I'm assuming if you phoned British Gas and asked for a quote, once the engineer is in your house, you will qualify for the £150 price.
