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?
YouTube how to videos never show you the bit where you undo the radiator valve and dirty water pisses up the wall. Managed to get the valve changed tho, hopefully that fixes the cold rad.
Plumber was supposed to turn up today but in the Socialist Republic of Britain nothing works as it should.
Itβs amazing how lucky we are in the UK, you can pay Β£15k for solar pv and a battery and youβll be privileged enough to pay the same for electricity as you did all those years ago in 2021
