Hi,
I am building a new house and haveing a solar hot water system installed. its will have a hot water tank with a second coil to connect another heat source to. I want to connect a wood burner to the second coil to heat the tank in the winter and also run abotu 10 rads. The problem i have is its an unvented system and wonder if i can install an expession vessel within a few meters of the wood burner. The hot water tank will be located 1m behind the log burner and about 1 m off the ground, so hope this will allow for gravity feeding when the punp is off. Any help would be great
Thanks -

It will not be a problem so long as the f/e tank is above the highest rad.
You will run the hot water off gravity but put a pipe stat on the primary flow which will switch on the pump and send the hot water around rads when the domestic hot water is up to temp. -

Danger! I think that you should start from first principles and design yourself a system that will do what you want it to. Not add on or modify something else.
Presumably you have not got anything as yet? So this is pencil exercise. -

You can run a vented system for the rads and connect the stove to it, run another loop from the stove to the tank, again vented.
If you want to heat the rads via your pressurised system then you might consider a plate heat exchange of some sort......
You cannot run a pressurised system with a stove boiler not designed to be pressurised as the boiler is not made to take the pressure. Some are, most aren't
Consult an experienced heating engineer....
