I've recently got myself a 80w solar panel and some deep cycle batteries + Invertor. I was wondering if it is possible to create free heat ect. Aanyway looking into low power heater and i find that around 500w is the smallest decent heater i can find. I know my current solar panel won't run it for long (do have a wind turbine too). Anyway, i looked at the costs and running a 500w heater should cost around £0.15p per hour, but yet running a 24kw central heating is £2.76. I wondered if anyone else had looked at these figures before. I know that the central heating warms the whole house up.
