I have a Baxi 51/3 RS boiler (standard system with HW Cylinder)
I've been having what appearing to be circulation problem for some time as the rads do not get very hot (and take a long time to warm up) and the HW also takes a dogs age to warm up.
The boiler also kettles (sounds like it's boiling water inside)
On touching the boiler flow and return (22mm pipes) i noticed that the flow is very hot (obviously) but the return is tepid.
Would this suggest a blockage or is a cold/tepid return normal?
