Heat pump monitoring survey
This direct survey of consumers finds leak rates higher than industry estimates.
Our heat pump efficiency revisited
With leaks fixed, the final results of efficiency measurement are pretty good for both of our pumps.
Measuring heat pump performance
This post details our approach to measuring the performance of the two heat pumps in our two-family home in the current heating season.
Learning from Maine
Recently, many have celebrated Maine’s achievement of 100,000 heat pumps installed. It’s really a good-news/bad-news story.
Tracking climate progress
We cannot assume that we are materially reducing greenhouse gas emissions just by putting heat pumps into homes at scale. Additional metrics are necessary to assure that we are benefitting the climate. Our climate report card should include those metrics.
