The stove as got thermostaic control, fired it up yesterday working like a dream! Have installed the cold feed and the vent to the return to the boiler with no valves inbetween the piping to the boiler, fitted the pump on the flow out of the boiler! [FONT=&]I no its against regs[/FONT] but its my 1st stove and with laision with the customer he was happy to go ahead with it! From now on going to install a gravity circuit and wont be installing a stove into nothing but a 2 story with a upstair double coil hwc! Some people may argue[FONT=&] its unsafe[/FONT] but dont see how it can be when you have a unobstructed from the cold feed and vent to the boiler???
