Hi all
our boiler is a Vaillant TurboMax. When the heating is up full, the radiators are too hot too touch in all parts of the house.
When the hot water is turned on, it gets hot, but not as hot as the radiators get.
The boiler is one end of the house, with a 10m pipe-run in the loft to the bathroom and kitchen. The pipes fully lagged.
I used to think it was loosing heat through this pipe-run, but it suddenly dawned on me the CH pipes have the same run - more in fact.
Is it possible there's a fault with the boiler ?
regards all
