had the exact conversation with a tech from a UK HP manufacturer. He was adamant that the 'need' for an inverter was driven not from efficiency but from the end user believing them to be more efficient. (baffle with BS)

Of course I remain firm ASHP's are all a load of ****e and wouldn't want one within a 100 yards of my 95% efficient gas combi.
I can only see two possible reasons for ASHP's

1 no gas
2 when combined with solar.

Without those gas beats HP's into the ground over a 365 day period and even the g.ment figures back this up
