You are assuming that those 45W of electricity are converted to 45W of

We can all warm ourselves up on your ears now!

There _are_losses with using electricity for heating. It doesn't matter
what you do with it once it's inside the house (unless you shine a big
light out of the window or something like that) as pretty well
everything that comes in on the wire will end up warming the house.

The losses are all in the generating plant and the transmission system.
These losses come to maybe 2/3 of the energy used. This is likely to
be a lot less than the losses in your gas boiler - so it's better to
heat with gas.
