I used 803kWh in the period of Feb to May last year. [email protected] and 214kWh @22.937p. The lower figure is described as secondary and the latter as primary. I cannot find an explanation for primary and secondary anywhere on my bill but I may have mislaid a page.
Fitted solar panels to our house a month ago and with it we got an "eco-eye" power monitor - the base load on our house is approx. 100w/h (includes fridge and everything else that we leave on stand-by.) - goes up when the heating comes on by about another 200w.
When my house is 'at rest', which includes the fridge and freezer already chilled is around 100watts, so the only things taking electric are the CCTV dvr and cameras, the TV and sky box on standby, the central heating clock and boiler and the house smoke detectors.
