Been thinking about making a miner positive input ventilation system. My house is an old Welsh farmhouse which costs a fortune to heat and is still damp and cold. Anybody had any experience with PIVs? Do they actually work or just add to your heating/leccy bill?

Trying out some plastering today. Sticking the boards to the wall was the easy bit, skimming it tomorrow is gonna be interesting!

It’s amazing how lucky we are in the UK, you can pay £15k for solar pv and a battery and you’ll be privileged enough to pay the same for electricity as you did all those years ago in 2021
