Has anyone here had any experience of using any of the solar PV water heating add-ons?
I mean those gadgets that monitor the power use from / to the grid on properties that have solar PV and when exporting more than, say, 70-100 watts, divert that same excess power into a resistive (sp?) load such as an immersion heater.
I've been looking at Solar iBoost+ which looks fairly simple to fit myself. With a clamp on the correct feed wire by the mains in and a box to install by the immersion, as long as I can tell live from neutral from earth I should be all right.
I know that the payback for these is quite long when using gas for water heating but there is the environmental side to it too. With the country having quite long periods of coal-free electricity generation it would be nice if I could have periods of gas-free hot water production!
Interested in others' experience of these sort of products.
Thanks in advance
