Air Source Heat Pumps

The install was 21K for roughly 7.5 kw potential, but that was as we went for in roof panels for looks rather than the normal install. Yes 10Kwh battery, but also the auto backup for power cuts (which we get annoyingly frequently).

It’s not randomly picked months, it was last month- February which is one of the worst of the year, and the saving was over 400 quid. We are in the south so that helps, but the maths still add up to way more than your break point.

Like I said I am no champion of solar, but if you’ve got a reasonable sized roof facing the right way it is at least worth doing the maths properly, taking into account usage and the tariffs available.

Do not go too far into this, once he has a view point he becomes as contrary as Mary to any logic.

Rear of his house is I’m guessing north facing from the photos shared & plastic grass. So the front would work but perhaps neighbours frown on such things.

I’ve evaluated the same process as you & can’t see where the issue lies, lots of neighbours done similar, so can’t just be my daftness here.

You are very right, I don’t really care as the maths work for us (and I am reasonably sensible ), and his opinion is based on a belief rather than facts.
