Two or three of the upstairs radiators get hot when the hot tank is calling for heat and the central heating is off.
New 3 port value fitted (old one knackered) problem still persists.
Inherited problem from moving in. Any suggestions for cure welcome
I'm looking to replace my oil boiler with one that sits outside the house.
I have been advised that a Grant Vortex Pro-Outdoor 15/21 is my best bet.
Any views as to price/quality/ reliability of this and other suitable oil boilers gratefully received.
