We have some conservation rooflights which the paint is starting to fail on. Like these https://www.therooflightcompany.co.uk/all-products/conservation/ To be frank the the rooflights are pretty poor thermally. Steel frames which get condensate which drips in to the room. I was a furniture maker in a previous life and was considering making some wooden openers (the frame set into the roof looks OK). Was thinking of laminating the frames for stability and sealing them in epoxy. Also not sure if high spec DG or triple glazing would be more sensible. Any thoughts on the matter would be much appreciated

There is a thermometer fitted but it has no influence over the GSHPs running. You can alter how much influence it has but I was told the system would be most efficient with it run 100% from the outside thermometer and the weather compensation so I had it set that way at the start and have never changed it in 10years

Our GSHP has this. You set it up manually and adjust the heat curve until you obtain steady internal temps. How it technically does it I couldn't say for sure but it can see the outgoing and return temps on the UFH and knows the external temp. Ours will keep the house within 1 degree C unless I run the wood burner

Hi all. Not done much 'eco' work on the house for some years but now with sky high electricity costs interested in extra PV combined with battery storage plus an agile tariff. Going to have a look through old threads to learn more about the subject Thanks
