Having a long large roomed house we have 2 heat-pumps & are still low power discount users.

The most expensive way to use a heat-pump is to switch it on & off, or use it on auto.
We set ours to heat to18 deg & leave them to it 24/7 all Winter.
We use a log burner to heat the water when needed (or just for the sight of logs burning) so when it is going & the temp is above 18 the heat-pumps go on stand by.
When the temp falls below 18 they kick in, thereby never having to do a great power eating boost to reach ambient temp.
We are very happy with their economy compared with electric or gas heating.
