Any advice on the most efficient way of transferring solar energy falling on flat roofs on the south facing part of the house to a cold north facing room on the ground floor would be much appreciated.
Here is the background: 1928 semi in, effectively, its original state, garden to south. We will insulate floors (taking up the boards and putting insulation between joists), walls (externally where appropriate), and roof (also creating an attic room with flat roof), and replace all windows with double/triple glazed.
Heating system to be 500L thermal store with the following energy inputs 1. wood-fired stove in snug on ground floor, with back boiler 2. solar thermal on angled frames on flat roof of attic 3. existing gas boiler as backup
At the moment (April) all the south facing rooms are an ideal temperature even without insulation, and no heating, but the north facing room is too cold to work in! Can we transfer solar energy directly from a south facing wall/roof to underfloor heating in the north facing room, or should we connect up the underfloor heating to the thermal store?
Wood fired boiler in north facing room not possible (it is a music room and needs to have an even source of heat so as not to damage instruments). Wood floor also ideal for sound, even though underfloor & wood is not ideal.
Thanks, Orlando
PS is 500L the right size for a thermal store for a three-bed semi?
