Hi i am a plumbing enthusiast (not a plumber) i have a genuine interest in how things work mainly in case things break iv a good genuine knowledge of how to or what needs to be repaired. iv recently moved propertys and the new house has what i believe to be a open vented gravity fed back boiler heating system (very old). When i look in the cupboard to the side of the boiler in the kitchen there are 5 pipes. 1 is i believe the gas pipe to the boiler, 2 will be the hot water flow and returns and 2 will be the ch flow and return. there is a grunfos pump on 1 of the pipes which if im right in thinking will be the ch flow pipe.
Am i right in thinking that the hot water flow and return to the boiler simply goes upto the cylinder and back down to the boiler heating the water in the cylinder.
And the ch flow and return is pumped by the grunfos pump around the house and back to the boiler??? ????????
