Welcome @Ann_Kolodziejski, @Chris_Wilkinson & @Jonathan_Whitehead to our forum, it is great to have you on-board.
These are some great ideas for webinars.
I think this is definitely something which we should try and cover in future webinars. We are absolutely going to be hosting more on the heat-pumps in the future as there is a lot of energy for this topic at the moment. You might also want to check out the 4 part Heat Pumps for Beginners course which we ran last year if you haven’t seen it already.
This is a really good idea. Both insulation and draught proofing can turn out to be a lot more complicated than they first appear! Having a webinar on these would definitely be of interest to a lot of people.
This is something I hadn’t really thought about, but I have seen some images on the Thermal Imaging Camera thread where light fittings appear to be a source of cold-spots, definitely something worth investigating!
