Posted By: SteamyTea Trouble with storage heaters is they are uncontrollable on a short time scale (I know as I live with them) but they do convert near enough all the electrical power to heat so efficiency pretty high (maybe 90%)
Posted By: SuzPV for heating ... we had PV panels commissioned early June. By lucky chance an innovative heating engineer had installed a DPS thermal store a couple of years ago for gas central and water heating. It's got an immersion heater so I switched off the gas water heating (night and morning) and switched on the immersion heater midday. Turns out running the immersion heater for 2 hours 13.00 - 15.30 provides hot water right through the 22 hours to next boost. I'm going to try less time still. This sunny weather we use practically no electricity for water heating alone.Now in winter when we run the central heating radiators I plan to continue this. At least we should get some free electric heat. Radiators seem a much better bet than storage heaters, at least if there's an existing system. We'll see!
