    Central Heating and the modulating boiler.

    To start with it all seems to make sense, the TRV measures the room temperature and controls the radiator temperature to suit, as the water flow is restricted the by-pass valve lifts, and hotter water is returned to boiler, so the boiler is throttled back (modulated) so the heat exchanger is...

    Is an annual boiler service important?

    I had this LPG and gas boiler servicing Tavistock expert install a new boiler in my apartment. And since I just got it, I honestly don’t think that servicing it annually is that important like what my brother think so. Want to know your opinions about this. Anybody?
