Hi Guys and thanks in advance for your guidance in this matter. I am currently helping a frien replace his heating aboard his narrow boat and wondered if I could pick your brains ? He currently has a wood burner with back boiler heating a radiator and Calorifier on gravity fed pipework .
not sure why but this system isn’t very effective ( even the wood burner doesn’t seem to get awfully hot)
so it seems that this system is fed via single pipe header tank , but also this header tank seems to feed the pipework coming from the engine to the calorifier as well? Now my question is , is this correct or should there be two separate tanks ? As some of the pipework is difficult to see or get to it’s a little tricky to see the exact layout? Would anyone have a simple diagram of how this system should be plumbed ( and perhaps any advice along the way would be great !
be gentle we are new to all this malarkey !
cheers
Neill
