I recently had to get a replacement heat pump. In the process I discovered that the EU has a database of energy ratings for almost (actually?) all electric appliances sold in the eu. This includes heat pumps.
I scraped the heat pump data and am the proud owner of 100% of this information. What I found is that some of the available data is inaccurate and much of the energy ratings (A-G character rating) is inconsistent with the performance of the device, probably due to changing standards over the years. It’s nice to see initiatives like this which hopefully will provide better and more normalized data.
As a side note. Air-to-air heat pumps have, as most people know, two parts to it. The indoor unit, and the outdoor unit. Many models can be used interchangeably, so the domain of heat pumps is a bit more complicated than I first anticipated.
- jonasdegendt 2y agoTo my knowledge, the A-G energy rating is a rolling standard. It gets a little bit tougher to make A grade every year. NCAP works the same way.
