Central Heating question

Hi all, Just moved house with the misses and have central heating. I used to have it few years ago when i lived alone in a flat but never used it. I have some questions regarding the combi boiler. ill start with what i think is an easy one

what tempreture would you all suggest for the hot water on the combi boiler?

the second one is probably a simple one, but im confused. regardin the central heating, im assuming once the combi boiler is set.. i use the thermostat near the stairs to control the tempreture? thats fair enough, but the combi boiler has a few settings for the central heating

OFF
Continuously on
Temporary On

continously on scares the hell out of me as i dont fancy getting a whopping great gas bill. (unless im mistaken)

the manual can be found here http://www.intergasheating.co.uk/lij...82.887-031.pdf for anyone who wouldnt mind taking a look at talking me through the basics.

I have hot water on full as I have a shower, the central heating depends on how you live. If you have it on continuously then you can set the thermostat at a comfortable temptature and it will click on and off to maintain that temperature. If the house lies empty for hours on end then there is no point keeping the house warm at those times so you'd be better with a timer

Eco on my washing Mashine and dishwasher saves energy by using less water, maybe it restricts the flow of hot water?

A lot of combi boilers now have a fixed water temperature of 60c (too hot for me!).

All but one of your radiators should have a TRV fitted that control that room's temperature. The one without a TRV should be where the wall thermostat is (hallway usually).

Letting a house cool whilst you're out is possibly a bad thing as it may need quite a while, and thus a lot of energy to get the house warmed up again. Check for decent wall and roof insulation!

thanks guys. ive left the heating on for now. see what the damage is when i get the bill i guess. hope it isnt to high lol.

Get yourself a programmable thermostat; you programme it with a temperature profile so it comes on first thing in the morning when you get up, reduces to say 18 degrees when you go out and comes back up to temp just before you get home then down to 15 degrees overnight.

Can also be locked to a specific temp if you are in all day say.
