open fire and oil boiler

[CXR100]

is It possible to connect to a open fire already installed to feed gravity hot water and pumped heating , a conventional oil boiler boiler, its in my own house, never done it before , asked some other plumbers and they said that you can do it with a 3 port valve , there must be a way to do it. can anybody help me out. thanks

dunsley baker neutralizer link-up system

H2 control system

These are worth a read/look at.

Strange for any plumber to say use 3 port valve! You have a gravity circuit and a pumped circuit.
The Dunsley neutraliser is what it says, - a neutral point for gravity circuit and pumped. Just need gravity circuit from fire joined to the Dunsley unit and the oil boiler pumped pipes and exiting pipes also joined to other tappings.

Or you can use a twin coil cylinder. This will mean the gravity coil and the pumped coil are separate. Then the only circuit you connect is the pumped radiator circuit, but using a check valve at each boilers pumped pipes to avoid one boiler heating the other and also resulting in bypassing

Thermal store system far preferable to twin coil cylinder
