New heat pump system in new house

cheezums

Hi all

I have a new Hitachi Yutaki system in a new build. The house is well insulated, underfloor heating downstairs and rads upstairs. it's working perfectly. my only question is should it be left on all the time in winter? I'm reading conflicting advice all over the internet. some say it will cost more to heat up the house after having been off for several hours. Others say it's way more expensive to have it on all the time and it should be off at night. Apologies if there is a thread for this already. What's the general thinking here?

Most will advise you to leave them on and let your thermostats control the zones.

Because of the slow response time, you might find that turning on/off will not give a satisfactory level of comfort.

It might be a good idea to jot down your meter reading every day or two to get a sense for how much electricity you are actually consuming, to get confidence in the system as much as anything else.

The sensible thing is to let the stats control the system. You can’t just expect to be able to turn it on when it is chilly.

What about running it on a solar system I don't know costs but it is something I am interested in as it's a handy system for people that have a holiday home in Spain or somewhere warm & want to spend the winter months there & have there hose kept heated at home.

I am thinking about it at the moment I own my house & am thinking of selling it & buying something smaller here & apartment in Spain. House prices are high here at the moment & won't last long.
