Electric water heater
Would it be more economical to run a electric water heater in addition to an installed heat pump, but changing that to solely run the heating circulation.❓

Hi, im not quite sure that I understand what you are asking, but an electric heater will have close to 100% efficiency whereas a heat pump will have several times that efficiency depending on the temperature to which the water is heated and the outside temperature. Hope that helps

Sorry I was probably being vague but I was thinking out loud along the lines of something like this. I guess it was knee jerk to thinking I could run two heating systems (think I'd had a beer at the time so wasn't thinking!) 1. Just for hot water and 2. For heating alone as the heat pump won't deliver heat whilst it's heating the water. I think I've answered the question myself by just getting a solar diverter.
I've put the articles on anyway just out of interest, although again it probably more orientated to Australia!

In relation to this article where they are saying electric water heaters may be better at storing energy versus a battery used to heat the water in a cylinder.

Your HP should be able to provide hot water in between heating the house, a HP heated house should have a back-up electric water heater anyway.
@bretix I think they are essentially saying that renewable energy can be stored as heat in a water tank! Stop the press 😀
