Is This Bloke Completely Barking.............

I wonder how much a 250W panel and inverter costs, and whether this whizzo scheme is economically viable.

As it is a 250W element, it might need a bigger panel as I believe they mostly run below their nominal output.

Nice blue overalls. I bet he uses boss white and hemp, not PTFE.

I've lost track of the number of times I've had "conversations" with people that genuinely believe that it costs the same to heat "a full tank" of water when you only drew off (say) half a tank as it would if you started from cold. So this sort of thing doesn't surprise me in the least.

My mother told me off for leaving electric sockets switched on when there was nothing plugged in; the electric would run out onto the floor and be wasted. She grew up a long way from electric lights.

There again, she never tried to pass on her technical wisdom with a Youtube video. It's called You Tube for a reason.

Some people haven't had the benefit of the technical education that we now take for granted, not because they're thick, more that I (we) were just lucky.

He really made life difficult for himself. If he just wanted to heat hot water why not install a twin coil cylinder and pumped system.

Nah, that would be too easy - and probably far too efficient.

And I was also thinking, why bother with the inverter ? Just feed the DC into the heater. Allowing for the DC not being 250V, you might find that a standard immersion heater would do as a load.
