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...
