Thanks, @Eric_Fewster and @Tim_Gilbert. In addition to hoping for an air -to-water heat pump (or possibly water-to-water, as we have a spring) for heating most of the house, I am beginning to wonder about combining it with an air-to-air heat pump for our currently unheated kitchen extension and kitchen, our second gas fan convector in there having given up the ghost several years ago. The advantage of this solution would be that the air-to-air could also give us cooling in that one room in hot summer weather, along the lines of the CCC report you have posted here yesterday @Tim_Gilbert. But on the face of it, the BUS grant will only be allowed for a heat pump which would heat the whole house. So our air-to-water heat pump will be oversized and needlessly expensive to purchase, as it doesn’t need to heat that room, because our air source heat pump can heat (or cool) that. It will be a shame if I am correct that an unintended consequence of the BUS grant scheme is to prevent us from having grant support to do just what the CCC and building science community would probably commend as the best solution for tens of thousands of houses similar to ours, and will require us to install a superfluous radiator in the kitchen extension. Can anyone see an ingenious way around this problem with the grant, I wonder?
You are correct that the BUS grant is for one heat pump to heat the whole house and hot water along the lines of a boiler.
I know of people who successfully got the grant even though they had air conditioning, so a/c clearly doesn’t prevent the grant being allowed but as far as I know the wet system was installed throughout.
How over the top do you want to go?
Or put it another way, how long do you want your adaptations to be relevant before the warming climate outsmarts them?
Here is some very serious advice!
I think there is a lot in here that can inspire us here in the UK, without the need to go all the way.
Apparently it is Global Heat Action Day and timed to go with it is this report on global overheating at night.
I have recently spotted this item as a candidate for movable external window shading on simple hinges
Mounted with a ventilation gap behind this looks good.
How would you mount them to avoid introducing thermal bridging into the wall structure? That is a general question, not specific to this type of shading.
I’m contemplating sails over some of our windows but they need fairly heavy bolts to not only support them but also resist wind forces.
This thread and I get mentions in the latest edition of the Carbon Co-op members’ newsletter.
In my acceptance speech I would like to thank all those who have contributed.
