I am shifting into a new home (double glazed) in about a month, when it is finished. I'll have two heat pumps one in the main bedroom and one in the lounge, the question: am I better (power wise) to set them to 22° and leave them both permanently on during winter or switch them on and off when I'm there!. I know I can suck it and see but someone may have a view.
Thanks.

A well insulated, double glazed, average sized home built to the sun is not going to get very cold during the day while the sun shines anyway and it would come to temperature relatively quickly using a heat pump compared to an older, single glazed home not well oriented toward the sun and leaks heat.
You’ll find that a heat pump is very energy efficient so I would leave it set on the desired temperature to come on when need be. The sun may be doing the heating for you during the day, when it shines, so the heat pump will mostly run at night and cloudy wet days.
We had bought an older pre-1980 work premises built with concrete block walls and I didn’t like the thought of the heat pumps running day and night to heat the place which was like an ice block, but it did take longer to come to temperature during the day when the the heat pumps were turned off at night, so we just kept them on. The other building built in 1994 was a bit better insulated/designed and the heat pumps would come on an hour or so before people came to work and turn off at the end of the day, running during the working days only.
In the South Island, I would probably have triple glazing but in the north island its easier to heat a modern house with heat pumps.
Thank you so much for your comments, the place is built to the sun plus it is well insulated including the garage and garage door. When I shift in I'll switch them on and leave them on and then check the power bill and review if necessary.
However someone else may care to offer their views as well!

optimum efficiency is when the difference between outside and inside temperature is very small. There is a loss of efficiency as temperature decreases below 6–7ºC
Dollar for dollar, the oil filled heaters are hard to beat.
