The idea of having a net zero home, one that generates as much power as it consumes, is very exciting. Some people are interested in it to help save the planet, others like the idea of never paying another power bill, or the freedom of energy independence. For a long time, net zero homes were so expensive and complicated that they were simply dreams for most people. In this post I’ll explain how I did it, and how you can to.
Upgrading an old oil furnace and AC unit to a new high efficiency heat pump has been one of the two keys to making my family’s home in PA produce more energy than it consumes (the other of course was adding a big fat solar array). Now that we’ve lived in the house for over a year I thought it would be a good time to look back at the data and see what sort of return on investment (ROI) this heat pump has given us.
