I am a gas safe registered engineer, I have been asked by customer to change oil boiler for gas boiler.The conventional oil boiler is floor mounted with pumped heating circulation pipes but gravity hot water coil connection. There is also a solid fuel wood burner which flow and return are connected in as also heat water.I am unsure of how these are linked in as not visible, will have to lift floorboards. How should these be connected? With the new gas boiler it will have to be fully pumped but will the pump effect the configuration of the linked system? i looked into it and it says to use a neutral point manifold is this correct? will this be all i will need to join system? they want to keep the cylinder as it is as an open vented system so the only other option is to change cylinder for two coil and seperate from solid fuel.
Any advice greatly appreciated
thanks
