We started the session out on the field looking at the house from the south east. Everybody arrived at 12, so it became a single long session with plenty of time for questions.
Here is my Powerpoint for the Open Day, although I didn't get a chance to deliver it, because we were all so busy communicating directly.
Most people were there for their interest in Photovoltaic, but there was also interest in the Surya sunboxes for those who were considering heatpumps, especially now that I am more aware of their performance, and contribution.
There was one couple who already have a heat pump, but it is air source, and every year it is unable to cope in the colder parts of the winter, so they have a 'bivalent' system, meaning that it switches over to the oil central heating when the ASHP gives up. I wish they had a ground source heat pump like mine, so that it could bivalently switch over to Sunboxes like the one in Peveril Solar house!
