I am particularly impressed by how little power is now required to heat my house. I have a meter monitoring how much power is being taken from my mains supply and this shows that to keep my whole house reasonably warm takes about 400W. I have an installed gas system and since the Hitachi units have been installed, this system has only been on to heat my water supply. I anticipate a big saving my heating bill. An added bonus is that it will provide cooling during the few hot days of summer.
The operating handbook could be better but this is not a major problem.
