What’s the deal with heat pumps?

Friday, November 15th, 2013

Richard Faesy from the Energy Futures Group and an Energy Co-op of Vermont Board member, provided us with this article about heat pumps. We thought we should pass it along to you:

“Heat pumps seem to be in the news recently. In April, Efficiency Vermont launched a new program promoting them and Green Mountain Power recently launched a heat pump rental program that appears to be wildly successful. They expected to hear from about 200 customers but, instead, received inquiries from more than 600. What gives?

BSR members are intrigued with the technology and are excited to see heat pumps designed for Vermont’s climate now available at reasonable costs. Besides biomass, we now have a fossil fuel alternative that can automatically heat (and even cool) our homes at about half the operating cost of oil or propane. And since heat pumps run off electricity, we can now deliver zero net-energy heating and cooling systems by adding PV panels to off-set the heat pump load. If all this is so good, what’s the catch? Is this another one of those “too good to be true” technologies that will be gone after an initial flash in the pan?

Actually, heat pumps have been around for decades and are the primary means of heating and cooling buildings in most of the world outside of North America. The technology is the same as that used in refrigerators to concentrate heat and move it from one place to another. With a refrigerator, it works to gather up the heat in the food storage area and then dump it into the kitchen. With today’s heat pumps, in winter they concentrate heat from outside (even in temperatures down below 15 degrees below zero) and then deliver it inside. In the summer they do the opposite to cool the building by moving heat from inside to outside.

While we have been installing “ground-source” heat pumps in the Northeast for decades that are able to move heat between buildings and the ground (or water wells within the ground), they tend to be pricey, typically $20,000 to $40,000 installed. The new “air-source” heat pumps do not require drilling expensive wells or digging long trenches as are necessary for the ground source units, and can be installed for about $4,000 per unit for those systems that work in Vermont’s “cold climate”. These “cold-climate air-source” heat pumps can provide up to about 20,000 Btu/hour, so you would typically need a few systems for a well-insulated tight Vermont house, provided the layout works to allow heat distribution. For two systems, that’s $8,000; not bad for a heating and cooling system that cuts oil bills in half!

If you want to know more about which units work best in Vermont’s winters and what incentives are available for installing cold climate heat pumps in existing homes to displace oil and propane, take a look at Efficiency Vermont’s heat pump page.

To find out more about direct experience with this technology in real Vermont homes, installation issues, costs, applicability in certain homes and more, come to a panel discussion at On The Rise Bakery in Richmond, November 25, 2013 at 7:00 p.m. We hope to see you there.”

Here at the Energy Co-op, we’ve known of heat pumps for a few years, and install Mitsubishi heat pumps around northwestern Vermont. Right now, Co-op Guardian Plan members receive 0% financing and a 10% discount on our Mitsubishi heat pump line.

How Energy Efficient is Vermont?

Monday, November 11th, 2013

The American Council for an Energy Efficient Economy (ACEEE) is a quiet policy heavyweight on all things energy efficiency. Not only do they inform policymakers around the country about the latest in efficiency measures and technology, but they also regularly review and rank state efficiency programs in their State Energy Efficiency Scorecard. The scorecard serves as one of the more important benchmarks for state efforts on energy efficient policies and programs. This is important as more and more states figure out how they can save millions of dollars tomorrow by investing in efficiency programs and technology today.

This year,Vermont was ranked at #7 in the country when it comes to energy efficiency. Some might ask, “why so low?” The main reason is related to transportation, which of course is related to the fact Vermont, a rural state, doesn’t have much capacity for public transportation. Yet, while we Vermonters didn’t score high on transportation efficiency, we ranked in the top five in utility efficiency thanks mainly to the outstanding work of Efficiency Vermont. You can checkout the one-page summary of Vermont efficiency programs here.

We at the Energy Co-op have always made energy efficiency a priority. Since the co-op model is focused on delivering the best possible service and support to our members and customers, instead of worrying about the bottom line, we can spend more time working on our energy efficiency goals. Lucky for us, Vermonters have a long history of respect for the co-op model – and for using resources wisely. Click here for stories about Co-op members who have made efficiency improvements to their homes.

The Energy Co-op is not only helping homeowners button-up their homes, service their heating equipment and get low prices on heating oil, we’re also introducing new and efficient ways to heat and cool your home. Pellet stoves, heat pumps and solar hot water heaters are three examples of these new technologies.

We hope next year, when the ACEEE scorecard comes out,Vermont ranks a bit higher, maybe because of the some of the work we’re committed to doing here in the Green Mountain State.
