Managed to get the heating and hot water sorted, but no idea how! I'm buying a new boiler no matter what, as this one is just becoming too unreliable these days. Been stuck at home the last few days, and thought I would be able to get a lot of video stuff done, write-ups and the like, but it developed into extreme apathy! I'm trying to post on here as soon as I can think of anything worthwhile​... but the motivational side is difficult... Still I'll keep at it... see how it all goes!
