ASHs to ASHs11 Apr 2023 16:47
Air Source Heat pumps. I've been trying to find out the size rads I'd need in my house (gas CH, solid floors, built 1994) and another (built c.1920, gas CH, solid walls) if I chose ASH. I am struggling to get this information without getting a salesman around. I believe this sort of information is deliberately hidden or kept vague. It isn't rocket science. Any assistance will be gratefully appreciated. I have known about ASH pumps since c.2010 and the physics won't have changed.
The public are being fed propaganda and ignoring the cost of electricity, the sheer expense of converting to ASH pumps is horrendous. Mainly due to the need of oversize rads which entails redecoration on top of the expense of changing the rads. The cost of solid wall insulation also requires redecoration and adjustment to electric points inside, gutters outside etc. Even then, when after ticking all the boxes some regret their decision. Can you trust the future price of electricity? They say the air is FREE but that isn't the case if you live in London and drive in the wrong place or have the wrong type of transport (think thin edge and wedges). For new-builds it is a different story if ASH is designed in. However, the take-up will be tiny as we just aren't building enough new properties so the housing stock standard will be little changed imo by 2050 with only new builds being compliant.
This isn't the reason for the post though. Much to my surprise my daughter knows what an EPC is and I see a storm coming. People will look at several properties and it won't always be a seller's market. The EPC kinda tells the truth (I've done hundreds) but it is quite a blunt instrument and many are wrongly surveyed anyway. I would ask to look at utility bills with special attention to the heating costs. The seller will always brag about the benefits but the utility bills don't lie. They will also tell friends and colleagues if they have buyers remorse and the product hasn't lived up to its promises. Even poorly finished new-builds might be included. It can't happen soon enough for us but the government and more so the Labour opposition are living in a fool's paradise.
I'm sure most of you have had builders and plumbers round. Are you confident they understand and can fit the latest technology at prices we've gotten used to? I'm not!
