Combi boiler into existing wood burner system

[Christopher644]

My parents house has a wood burning stove that is also connected to the central heating ( they have radiators and used to have an old boiler which they took out and replaced with the wood burner ) so the wood burner can also heat water which can then be pumped round the rads and works fine when kept stoked up. But ideally would like a combi boiler that can be used normally for the central heating so it could be put on a timer etc.
Would this be possible to install a conventional combi boiler into this system and how would be the best way of doing it?
Thanks.

Would be with a thermal store in place of hot water cylinder.
I recommend you do some research in that direction.
Also could look at plate to plate heat exchanger.
Either way you'll need to separate the two heating circuits.

Thanks for your reply. Yeah as far as I know it’s a wood stove with a tank on top that has water in it that then can be pumped around the rads once it’s reached a certain temperature so it’s all linked up to the central heating.
So if a combi boiler was installed to heat the rads instead and keep the wood stove as primarily heat just for the room it’s in then we would be looking at this heat exchanger possibly?
Thanks again for the info.

You could prob have two circuits joined by a plate heat exchanger so could use either one as a heat source. In my head you'd keep as is with heating circuit and install HEX to sink heat from combi into rad/hw circuit (think pool heater). In my head you could run both simultaneously as the heat from log fire would in theory hold off boiler.
It's not really something ive seen outside district heating. Usually you'd look at a thermal store.
