How up to date are the prices on the site?
The prices are all updated automatically once a year using latest data from government sources and fuel retailers. Once the prices are updated all the site calculations automatically recalculate. So the site never significantly goes out of date.
Can an electric space heater be low consumption?
We have looked around the various claims on a few sites on the internet on this issue. Simply put no, but with one qualification. Electrical space heaters are all very efficient at converting electrical energy to heat, close to 100%. So they will all consume the same amount of electricity for the same heat output. The qualification is thermostats; a good thermostat is very useful at maintaining a room at a set temperature rather that continuing to heat a room which is already warm enough, having said that most space heaters have got thermostats on them.
So beware of claims on highly efficient low consumption electrical space heaters.
Your calculations on the PV solar energy miss out FITS, why?
FITS is the Feed in Tariff. This is where an artificially high price is paid for electricity generated by solar cells. We have left it out until now because it is an artificial government construct to encourage PV electrical generation and could go at any time, the reality of the economics of PV is all that is shown. We will however do something on this soon on FITS.
