We are very pleased with our heat pump and heat pump water heater. Joe and the rest of the staff at the Energy Co-op of Vermont were very professional. They were honest about what their products would do, and about our options. (For example, we may wish to add a second heat pump in the future because of how our house is laid out. Despite that, we rarely use our oil furnace now.) We are enjoying big savings and much lower fossil fuel use, since we have solar PV. I have recommended the Energy Co-op of Vermont to others.
