Feasible alternative to what, central heating and running hot water? Probably not in the UK at least. Ever.Is solar panels not yet feasible alternative, I read the price fell a lot
I have 2 solar banks and a solar heat exchanger on the house. In summer it prewarms the water so the boiler works less, in winter I imagine it only takes the chill off of it. I'd say it's never enough on its own.
The solar panels can produce maybe 5-6kWh on a summer's day but much less in winter, and of course no storage which would add inefficiencies.
