I think it was 3 summers ago I fitted a split aircon unit in my
living room. It's 12,000 BTU (3.5kW cooling and a bit more
heating, 3.8kW IIRC). This was after fitting a similar unit
for my parents, and being very impressed with it.

I've had a power meter on it all this year. Started using it in
the early spring to heat the room when I didn't need to heat the
whole house. Through the summer, it did some cooling, although
not as much as in previous years as it wasn't very hot. Used it
again for heating this week.

Should say last week (and today0.

Just checked the power meter, and
it's clocked up 60kWhrs, which comes to about £6.50, which is
much lower than I would have guessed had I not measured it.

Blimey!

I have considered fitting on in our underground bathroom (if that's
"legal" ) to replace the KW electric wall fan thing which never really
gets used.

If you don't use the fan heater, why do you need one?
I don't think I would use one for that purpose.
Aircon which has a reverse heating feature is useful for
supplementing heating at certain times of year, but it
doesn't work when outside temperature drops below around
5C, as it will spend more time (and likely power) deicing
the outside unit than it would heating indoors. So I
would not rely on it for primary heating.

Also beware that if installing in a basement, some units
which require the outdoor unit below the indoor unit may
not be suitable.
