This is all good stuff. And interesting But the point remains, electricity is going to go up, probably a lot. Not down as our gloourius leaders, and some on here kepp saying. There are significant consequences to that especially if other countries dont see those increases.

That wouldnt comply, A plastic duct isnt mechanical protection.

Yes! Scratching around for a old mole plough i can stick on the tractor. But, no idea what im actually doing!!!!

You will still get volt drop in DC. When i worked it all out and priced the cabling, it was cheaper to do A/C. Unless ive misunderstood something critical?

Be great if i could.

As ive mentioned before, i know a handful of people with heat pumps. None are happy. All are either cold, of finding it much more expensive to keep war,. Yes, that doesnt constitute a decent sample, i get that. Maybe just a co-incidence? That said, i recently met someone who is happy. But he is a heat pump installer, so i dont really count that. Thanks for the breakdown on cost. The most obvious thing is the cost of the pump and cylinder seem expensive compared to what i found and priced up. About double in fact. Im sure theres a reason you are using these specific ones ones though. When i strip and refurbish the house, i will need to significantly reconfigure the heating, and intended to make it heat pump "ready". Might need to revisit if this is the sort of cost of materials. Re-visit as in simplify. Or not bother. Anyway, appreciate you taking the time.

Sadly not. Its got to come across a field, then a driveway/yard. And i need to go big on cable size, because its, a) a long way so voltage drop becomes a real issue, b) if i want to increase the size of the array, which i almost certainly will as secondhand panels are so cheap now, i dont want to re-vsit the cable.

Its the 150m cable run thats the killer! That needs trenching in.

Couple of Q's You say their are "plenty" of good installers. What does "plenty" mean? There might be plenty, but if the majority are not good, then, realistically, unless you are in the know, its more likely, than not, you will get a "not good" job. Which is what seems to be happening in the real world. This house with £11k of materials, was it some kind of mansion? I struggle to see how this would cost £11k in materials on an "average" house. For mine doing a "johnmo" as it were and as suggested on this thread, you have a ASHP, a UVC, some sort of wiring/control center, some UFH pipe and some rads. I couldnt get that close to £11k in materials even if i tried.

By smaller cylinder, you mean a smaller UVC than you might otherwise install?

Whilst one can debate "existing V new" and the like, it is, to a large extent, acedemic. The point is still the same. Thats awfully expensive, and can only result in ever higher prices to the consumer. Those costs dont include any of the required infrastructure for distribution as i understand it. Summary. Electricity will get more expensive. Whatever government ministers might say. But we all know they lie, so i guess we shouldnt be surprised. In a way though, it gets the result you always wanted. Make it so expensive that we either use less or find another way to self generate. It certainly reduces my concern that my payback calculations could be undermined by reductions in electricity cost. Obviously wont be so good for those unable to invest in such measures because they dont have the capital. Nor the economy. Must get the solar panels planted this summer.

Gas is, i understand, circa £55 v yesterdays 20 year commitment to paying £95. 20 years! Guess i was right. Only one way for bills to go. Still makes it more viable to install solar and batteries etc. Meanwhile oil prices are going down and projected to stay that way in the short to medium term. Guess ill hang on to my oil boiler.

I found the only way to get rid of potholes in my road plannings permanently was to do it in the rain! Or at least the whacking part. Tended to drag the fines and a bit of mud/clay up and bind it all together. But as per saveasteading, properly clean out the hole first. Legend has it soaking in diesel also works but ive not tried that, and probably shouldnt.

Are you able to share that wheeze with us. That a very short payback. One i would consider.

Im inclined to think this is the most likely version of events, with its obvious effect in pricing. I dont need another expensive hobby.
