Octopus ASHP woes:
Apparently a structural engineer report/survey is needed to install the unvented cylinder (200L capacity + 50kg) in the airing cupboard, which currently has a 140 litre vented one. If its built for 140 litres 25 years ago, it should be able to support triple that if not more. £400 down the drain (still getting quotes, some were in the vicinity of £700+VAT)
Noise level to adjacent property would be 1dB higher (maybe) so we'll need to apply for a planning permission, even though it was a BS back-of-the-napkin calculation by the surveyor. They'll offer simple guidance in filling several forms but that's it. More ££
It's going on the front of the house adjacent to my office (was the "dining room", but we chose to eat in the cramped kitchen or conservatory instead) so I'm not sure of the noise levels on the other wide of the (double, cavity insulated) wall.
Our 80A main fuse needs to be upgraded to 100A but it still won't be enough if we don't decommission our electric shower, which we obviously will anyway. But needs more funds to get the plumber out to replace the bathtub-mounted taps to add a shower thingy.
They can't start the work without getting the supply unlooped, which we're waiting for 2 months and nothing has happened yet. More, next door has just sold so if the DNO comes and wants to dig out their front garden it will be interesting.
The hobs are gas, so we'd also need to replace the range cooker, which is another ~£1.5k down the drain. Since it's already on a separate 32A for its multiple ovens I don't think more electrics are needed.
Oh and we'd need to block off the chimney/flue/whatever. Which I'm fine with, but that's another cost item (and a person to deal with).
To add insult to injury they're suggesting to replace 10 radiators (!) so it's £3k after the BUS grant for us. Maybe just get a combi (when the boiler breaks in a few years) and let the next owners handle it in a few years?
