Heating on perma on vs timed

joe123

Hey all, just wondering can anyone shed some light in terms of best use of heating system.

So Im living in a B2 energy rating house - oil heating with a 2 zone heating + water.

Is it more cost effective to leave heating on permanent on and base it off the thermostat around 16 degrees or is it more cost efficient to have it on timed? If so how often should you time it to come on?

For water I just have it to come on for an hour a day which is fine. Im more interested to hear what should be the best for down and upstairs. Zone 1 and Zone 2.

Im also wondering what cost on the electricity (if any of substance) would having a heating system on permanent on?

Last part first. the electricity cost is mostly insignificant and even more so with a modern circulating pump.

The other part of your question always causes disagreement. But (and I've really studied this) The best use of yout heating system will be to have it on for the minium length of time that gives you the level of comfort that you require. To that end, set the zones to come on in time to heat the areas that you will be occupying to a temperature that is comfortable. (btw, not many would consider 16° very comfortable -especially after supper.)

You can have the heat in unoccupied areas on for just enough time to keep those areas from getting damp or mildewed.... so long as you isolate those areas from the areas that you are heating to a comfortable living standard.

As always, best insulation you can afford and minimise draughts. Also a well serviced boiler will also help.
