Hi folks,
I know this is the Electricians forum and this may be more relevant to a plumbers forum, but I wondered if I could get some advice or suggestions from you guys.
We`ve recently had a 3.5KW solar PV system fitted and it's working a treat, and I spent a considerable amount of time on here reading the various threads regarding taking the export energy and using that for an immersion heater which sounds like a good idea as (at the moment) we`ll get 50% of generation as export payments anyway. The actual product choice I don't know yet, and burst fire vs phase angle stuff whilst very interesting is not something I have any expertise in so I won't comment on that until I`ve done some more research into what those differences actually mean
So to my question, unfortunately I don't have a hot water cylinder in the house - all our hot water is provided by a combi-boiler which (I`m pretty sure) means I need an unvented *something*. I`ve been looking around at cylinders and thermal stores, but wondered what you guys have found most efficient for heating in this way (if any... maybe it's just the principal)?
I`m leaning towards a thermal store (accumulator) at the moment with backup from the combi so it can do hot water and maybe preheat the central heating somehow too, but a lot I have seen are more geared toward solar thermal rather than PV. I`m more interested in what would work better with something like an immersun or similar if you folks have any suggestions?
Cheers,
Matt
