#HomServ instal the new version for windows install

'attended site supplied & install a new Ariston unvent hot water cylinder in place of old vent system.heat tested all OK'. In my mind install means install professionally and in accordance with legal requirements. to also disconnect cold water storage tank and convert cold feed to mains. 'to supply and install a new Ariston unvented hot water cylinder with expansion. However, I have not been able to find the units in question. Think the same issue of routing cables applies if I use a diverter valve and in any case not sure I want to mess around in the boiler.Ī friend has advised me that the easiest solution involved fitting a wax thermostat into the gravity feed from the boiler, or maybe in the return from the tank, (not sure which) and that these are readily available and specifically made for this purpose. The result is that the hot water gets far too hot, though not so hot that it blows the pressure release valveOne obvious solution is to convert the boiler to pumped hot water, but I really don't want to go that way unless it is absolutely necessary (also routing cable from cylinder to boiler controller will not be that easy). as a result, the thermostat cannot be wired into the boiler controller without it turning off the central heating when the hot water cylinder reaches turn off temperature. I am not a plumber, as will become obvious, but I am an electrical engineer.Įarlier this summer I had the hot water cylinder replaced, professionally, and decided to do away with the header tank and go for a system where the hot water is at mains pressure, expansion is dealt with via an accumulator tank and venting is via a pressure relief valve.Īlthough the new cylinder has a thermostat, our boiler is pumped for the central heating and gravity for the hot water. First aplogies as a newcomer, if this has been asked before.
