I have seen mentioned two things that may help alleviate the effects of defrost cycles. The first is having sufficiently large thermal mass within t...
I'm not sure I follow. I have a 12kW Samsung ASHP, and starting from cold, which we do most mornings as we often switch off overnight, the system norm...
I generated 6.4kWh on Saturday 2.8kWh on Sunday and 7.4kWh yesterday from my south facing 3.65kWp array - Saturday and yesterday were very good days w...
I'm running a 'flat' WL curve of 32C (32C @ 15C OAT; 32C @ -2C OAT), and I then manually adjust LWT up and down on the controller heating screen. At t...
