Whilst I see the comments, this is a very foolish idea. The running cost will be immense, and oil is much cheaper, roughly the same as gas. The electrical supply may well not really be available, and I suspect there will be flickering lights and other difficulties. This is probably the least “green” idea I have seen so far, the overall efficiency from gas in to heat out is about half or less than using a new oil boiler. Whoever sold this needs to be locked up. The alternative of LPG is another possibility, again greater overall efficiency than the “electric” solution, and only a bit more than town gas.

Edit added:

The idea that electricity is in any way green is completely untrue, as is the suggestion that it is somehow “free”. On a good windy day, the wind and solar output are still miles from being enough, despite having “invested” a huge amount of money. The idea that fossil fuel will not somehow be available is also ridiculous and despite the “Boris” ideas, we will use fossil fuel for a long time yet, if only to enable us to get petrochemicals, the by-product of refining. Imagine the world without nail varnish remover or any plastic items, including cable insulation. We truly would be back in the dark ages! There really could be no electrical industry at all, and all the turbine blades would cease to exist, as would solar cells.
