|The house will appear in this gap|
They wanted me to know what is proposed so it can add to my research, but also, were keen to test out the ideas on me. They are building their own heat pump, so that it will be air source in summer and ground source in winter. They haven't yet settled on the type of collector they will use for the solar heat, but with ground charging this is less important - it does not have to be high temperature (like tubes). Perhaps they will use an adaptation of my sunbox!

At the moment, the building is not clear of the ground, all that can be seen is foundations and ground insulation. So there is time to make decisions. Simon is an expert on data collection and circuit design, and will be planting thermal sensors in many places in the ground under the house.
I hope to be able to report on this in future months.
(See comments below from Chris Wood, and I have amended the text above to include his observation)
27 Sept Postscript, email from Mo Kelly: "just to be clear our main heat delivery for the house will be what I describe as my Mono Energy System, the main components of this will be PVT panels tied directly into the HP the 2 main benefits of this is an all year round PV energy collection and between 10 and 15% better performance and night time usable primary source for the evaporation process of HP. I will update you on my plans for the overall storage of excess energy."
