Not even that. Small ASHPs are reasonably priced, a 30 kW one isn't. In some ways, people that consider swapping should do some research they should start with a basic energy course. I tried to get funding for one a decade ago, was told there was no interest because it had numbers in it.

Air tightness can be looked at in isolation. Where your insulation is, and what type it is, also has to be taken into account, as does humidity control. So it is not a simple case of just filling the gaps on the inside, it is why houses have breathable, but wind tight wrappings and vapour control membranes.

Yes, not sure how to get that message across, maybe a pointer to Zoot's thread, can that be retitled 'How to make your ASHP fail'.

I think ICE shows the basic manufacturing energy/carbon costs and the delivered costs on many of the products. Generally, transport is a very low cost, though a very visible one. Also, we pull down very few houses, I think a house built today will still be about, on average, in 500 years (read it somewhere, years ago)

My first thoughts, keep it on all the time, except when it is DHWing. As a general aside, all this nonsense about kWh/year is of little use. What is needed is 2 metrics, the power to keep the place warm at different temperature differences, so: kW/K And the power at different CoPs, so: kW/K @ x CoP

Do the numbers, if the ACH are a small fraction of the total losses, then there is little to be gained i.e. say 2 kWh/day via air change and 30 kWh via fabric losses.

But most would have gone to an incinerator to make electricity, possibly. And there is a bit of a myth that all timber eventually rots to CO2. Not the case, much is left as soil.

Won't getting a 3 Phase supply get around the problem easier?

Not many do.

CT1, sorts everything.

I don't think there is any way to know the size of the induction coil without looking, not sure if the manufacturers want to show how simple the insides are.

One things, is there enough water pressure, some washing machines are sensitive to this.

Is there data in the ICE from Bath? If not, email Steve Jones, he is very approachable.

Hopefully @ProDave will be along before then, he knows about this sort of thing better. And hot to earth things to stop the voltage floating. There are different electrical regs for caravans and outside stuff from generators.

Is the generator a pure sine wave one? Probably not. The washing machine electronics may not like anything else. Is the inverter big enough, and is that also a pure sine wave one?

Yours is a Carrier unit. If you buy from eBay, make sure you can get spares easily, i.e. control boards, it may be a zero volt switch, and command units, or you may not be able to configure properly. And get the original manufacturer's manual. And, and, check what refrigerant gas it uses.

You need to get the system balanced and the correct airflows. Then it will be cheaper to run, quieter, no noticeable drafts and feel just as fresh airy.

Welcome The answer, my friend, is blowing in the wind Even when doing 90 miles an hour down a dead end street But in the world of fibreglass, one is still looking for a gem Be careful of that travelin' salesman that I have heard about I can't go on, it is getting naff. Most Japanese and American units are fine, just make sure they are inverter types, and sized (oversized) correctly for your needs.

Turn it around, ask if they have any jobs going, point out that you are a specialist at cold calling and know about PV.

All it has every been really, just more fun to make it complicated.

Very easy to measure though.

No, I don’t find it necessary, for the few weeks a year that are hot enough, I enjoy it ?, saves paying fir a holiday to the south of Italy where the temps are that high anyway! We don't get exceptionally high summer temperatures, or exceptionally cold winter ones. We just get wind and rain.

My place is timber framed and can't remember any problems with insurance. It is 34 years old.
