I am currently planning the detailed layout of our new house and I would be very grateful for some advice.
The main heating (UFH) for the house will be an air source heat pump connected to a thermal store (either DPS or Akvaterm). We want to have a wood burning stove in the living room, mainly for the real fire effect rather than the heat so I was planning to get this connected to the thermal store to use most of the stove output to heat the DHW.
As I understand it, I need to have some sort of thermodynamically controlled heat dump in case of a power cut. I can fairly easily position a radiator upstairs almost directly above the wood burner so that should get round that problem. The thermal store, however, will be on the same floor as the wood burner and the other side of the house. The pipes to and from the thermal store will have to go up to the ceiling, across and then down to the thermal store.
Am I right in assuming that the loop to the thermal store will be driven by a thermostatically switched pump? Is it possible to have this loop open while the loop to the radiator upstairs is off? (I only want the radiator for emergency use if the loop to the thermal store is not working - I want the output from the wood burner to go the top of the store to provide the DHW). What I would like is that if there is a power cut then the loop to the radiator will open. Similarly, if the return from the thermal store gets too hot, then the radiator circuit should kick in.
I am not intending to install any of this myself but I would like to know if this is possible / standard / horribly complicated (i.e. expensive). If it sounds like a bit of a nightmare then I will keep it simple and just keep the wood burner for the occasional room warming fire.
Thanks very much.
