I have a woodburner with a 6kw output in a room requiring 2kw.
I also have an airsource heat pump for water and underfloor heating throughout the house.
I would like to salvage the excess heat and feed it into the airsource pump to reduce pump running cost and heat the other areas of the house....can anyone suggest an option?
The facetious answer would be to move your wood burner to a room with a higher heat requirement or trade it in for a smaller model :-)
I wouldn't advise attempting to cross connect this with your heat pump. Generally heat pumps are used 24 x 7 to provide a constant flow of small amounts of heat for underfloor heating etc, and generally wood burners are used occasionally to quickly raise the temperature in a room when it is occupied. I can foresee all sorts of potential problems in cross connecting them. I am not saying it can't be done, but I would advise caution.

Yes it can be done but not by linking to your heat pump. Your wood burner will need to have a back boiler fitted to it and some don't have this facility. That will allow the stove to provide hot water for use in your house. We have recently designed a house which has a hybrid heating system of heat pump and wood burners. The heat output from both goes to a thermal store, in effect a huge hot water cylinder. Both the domestic hot water and the central heating draw their heat demands from coils in the thermal store.
Alternatively you can install a hot water cylinder with an addtional coil for the wood burners output. Be warned; back boilers are pretty primitive and require old fashioned feed and expansion tanks and a dedicated radiator to take away surplus heat. The controls for these systems can get rather exotic and most UK heating engineers have little experience of hybrid systems. If you can speak good German then contact a German firm as they're commonplace in Germany.
Have just bought 1950s ex council flat in london and discovered it suffers heavy interstitial condensation (identified by a surveyor) in one bedroom particularly. Would a single room HR ventilator be the best solution and which maker is recommended?
