boiler what temp should it be set at
Discussion
hello need some advice on our new boiler
what temp should the central heating and hot water be set at ?
its a vaillant ecotec plus 937 and has a seperate dial for CH and HW at the moment the ch is set all the way to the left as in off i think hw knob is set at about 10 o'clock dont know exact temp as im not in front of it
oh and what pressure should there be in it
can anyone help ?

Central Heating should be set a 80 degrees for optimum performance from the radiators. Although its really down to personal preference.
Same with the Hot Water temp, personal preference.
Pressure should be set at 1.5 bar with the system cold.
I think with this boiler, if you press the minus button, it gives you a digital readout of the pressure.

Contrary to the above advice, the ch should NOT be set at 80C.
Condensing boilers run more efficiently on lower temperatures, and the lower the better in theory. In daily use, the main factor is the RETURN temperature which has a significant change around 55C. Couple of degrees above or a couple of degrees below can make a 10% difference in gas use.

Radiators are rated based on 80C. Reducing the temperature will significantly reduce the output, that's probably why you're using less gas Condensing boilers run more efficiently on lower temperatures, and the lower the better in theory.

Its the return temp. thats important with condensing boilers. Rads can be 80c, but needs to be balanced to get the return temp to support condensing which is where the extra efficiency comes from.Gassing Station | Homes, Gardens and DIY | Top of Page | What's New | My Stuff
