I have a Baxi Combi 80e & have recently noticed a problem. 3 of the upstairs radiators are getting hot when the boiler is serving only hot water.
With the central heating turned off & all the radiators cold I turn on one of the hot water taps. Within 5 minutes 3 of the 4 radiators upstairs are hot. Non of the other radiators, in the house, are affected.
Any ideas? Is there a directional value within the boiler that routes the water it heats?
