    Does setting the temperature on the boiler to a lower level/setting,mean lower gas bill??

    Also,what exactly does the temperature setting on the boiler do?

    Finally,what the best temp setting to have it at?

    Thanks.:)

    Basicilly the thermostat will control the temperature of the water in your radiators, the hotter the radiator the quicker the room and the thermostat in that room will tell the boiler to cut out.
    There are a lot of ifs and buts around the theory but basicilly thats it.

    Read the boiler's manual.

    If the condensation is successful you can't save more than you do already. Unless you throw away the boiler and by a more suitable one or you reduce the thermal demand.
    Read the gas usage and compare it with the amount of condensate the boiler generates.

    If you don't know what to do with the the numbers post them here and we'll check them.

    Im not having any trouble at all.Why you are insinuating that is beyond me though,typical of you to just jump to conclusions.

    I was merely asking a question that came into my mind when looking at the boiler temp setting the other day while making a cuppa tea in the kitchen.

    No harm is asking here,is there?

    I dont have large gas bills,and as allready stated to you on another thread,Im not starting out,Ive been on the property ladder for a good few years now.I own my own house too now,thanks to some wize and sound investments.

    My house is very modern,fully internaly insulated and has a brand new zoned heating system too,so its rather effiecent,I also have a new modern mutli fuel stove.

    So will you ever shut up with your snide/bitchy insinuating comments aimed at me,you did it on another thread,so shut up and give it a rest now.

    Thanks.

    The house and heating system is brand new,I was just wondering,while making a cuppa tea in the kitchen and looking at the boiler temp readout.

    Was just curious wanting to find out,thanks again.:)

    It's good that you are asking:). If it's a new system then more than likely it has been sized and calculated for a 70oC flow temperature setting to give the radiators the correct output. The Vokera Mynute HE boilers is also fully modulating which more or less means it is self learning. Providing it has been balanced and commisioned properly it will try to maintain a 20oC differance between the flow and return temperatures. Also there is a big missunderstanding out there regarding condensing boilers. At some point in there operation during a timing period usually when the room's are coming up to temperature the return temp will creep up to some 10oC from the flow and it's then when it dose not condense as much.

    What it boils down to is set it a 70oC and let it be. If you find that it's great at that then reduce it a bit if you want.

    Thanks....and thanks for the simple and straight forward explanations and advice too.:)
