I have a combi boiler that recently had a part fixed as the hot water wasn't getting to the radiators (the hot water in the taps was fine). Since then I now only get hot water to the taps if I switch the hot water to the radiators on as well. Any idea why? Will this be due to a mistake the plumber made when he fitted the last part?
Your boiler needs to maintain a minium water temp,so when cold water flows thru the domestic water coil heat is transferred and the water is warmed up.this water temp.setting is on the aquastat and it may have been lowered .I would call the company and explain the problem.I think I would like to have the boiler maintain 130 degree water for the domestic coil.
