> I do not fault the particular pump that we bought or our installers who were careful and professional. I feel like the author may be letting the installers off too easily here. It seems like there are two main possibilities: either no one understands how heat pumps actually work in the real world and none of them meet their claimed efficiencies (possible, but in my estimation not that likely) or the heat pumps he has installed are unsuited for their purpose (or badly installed). I'm inclined to suspect that he was sold the wrong heat pumps. Confirming this suspicion, in an earlier post (https://willbrownsberger.com/our-heat-pump-experience/#comme...) he gives the specs for his heat pumps. I don't know this particular model, but a commenter after him claims they are not the sort of "Cold Climate Heat Pumps" that would be appropriate for Massachusetts. Since this matches the symptoms (adequate heat production but low efficiency) I'm guessing this is the real issue here. I think heat pumps are a great technology, but worry there is going to be a backlash against them unless we can rein in the hype. And something is has gone really wrong if local installers can't be trusted to install a heat pump that is appropriate for the climate they are being installed in. Maybe the best thing he can do as a Massachusetts state senator is to enact more stringent laws preventing the installation of non-cold-climate heat pumps in Massachusetts so others don't suffer the disappointment that he did! |

Like buying any major appliance, unless you shell out a commercial fee for a commercial product and contract, you're just gonna be rolling the dice. You can do it yourself but the heat pump unit itself may still vary dramatically from sales specs.
