Gas Boiler v ASHP for Underfloor Heating

I manage to self use almost all the PV we generate and in a year the PV generates more than the heating uses in the winter.

Interesting, what is the Kw of your solar PVs ?

Perhaps he lives in Nigeria?

If you are also incorporating solar PV then an ASHP will make good use of spare "free" electricity.

I'd seriously doubt that.

Most need heating in the winter when it's ever so cold, the days are short and the sun doesn't shine very much meaning that solar panels will contribute very little to help heat the place. 

Oh yes it does.

Don't forget DHW heating.  With an ASHP you have a hot water cylinder, usually a large one.  By the simple act of setting the timer on my system so it only heats DHW from 11AM onwards, then there is a good chance that most of the DHW heating is done using up power generated by my solar PV.

I can't answer for @ProDave but my ASHP gets up to about 6 kW of power as the hot water nears its 50 C set temperature so he must  have a hulking great solar array.
