Very interesting to know that.. I've always known Inverters are pretty good
at heating, but not how they compared with energy use to say oil / gas
etc...

What brand did you fit / have fitted?

Airforce (B&Q own). They were £100 off when I bought them.
They should be only 5% VAT, but B&Q hadn't done the necessary
paperwork to charge reduced VAT on them. With the £100 off,
they were cheaper than all the suppliers charging 5% VAT at
the time, but that may well not be the case now -- I haven't
looked recently. I installed the self-fit ones. (They also did
the same models as professional fit at the time.)
