Any help on this matter greatly appreciated

We have just moved into a 3 storey house , that has gas central heating
boiler.

What is the ideal temp in 0c to operate this to heat the house.

weve been told different things by people we know , but im still
unsure.

I think that around 75 or 80c is right , yet someone else says 50c

also what would be ideal times for setting heating to ?? is is ideal
to have it on for say 2 hrs in am , and 2 hours at night , does that
use up more gas, or have it on for longer

The house:
The lowest temperature you can put up with _after_ you have put on a
sweater!

The boiler:
If you have a HW cylinder then set the flow temp to be around 10C higher
than the HWC temp. The HWC temp should be set to at least 50C but
otherwise as low as you can get away with on two counts:
1) The washing up
2) Making sure that there is enough HW for your needs, the cooler you
store the HW the less HW you will have stored up. This is because you will
be mixing it with less cold water as you use it.

If you have no HW cylinder then set the boiler as low as you can get away
with but which still heats the radiators up enough to make the house
comfortable.

Have the heating on as little as you can get away with.
Try to heat the HW up only just before you need it.

Try things on middling setting and then adjust them a little at a time
until they are what you want.
