To protect the health of our staff and our customers, Efficiency Vermont offices are closed to the public. We have cautiously begun scheduling project related site visits when required. You can find more information on our safety protocols here.
We know that you need support in reducing energy costs now more than ever, and we will continue to launch new offers and programs over the course of the summer. In the mean time, our customer support team is available to help you remotely. Contact us at (888) 921-5990 or email@example.com.
Furnaces & Boilers
Furnaces and boilers are a common way to heat in Vermont, with higher-efficiency systems saving more over time.
Furnaces and boilers are how most Vermonters heat their homes and businesses. Today’s models are up to 50% more efficient than those built pre-1995, saving you money and energy. Compatible fuels include propane, natural gas, oil, pellets, and wood. While a new furnace or boiler is a major expense, you’ll recoup the cost over time through lower energy bills. And if you weatherize your home or building, you may be able to buy a smaller, less expensive system.
Furnaces and Boilers: The Difference
Both furnaces and boilers produce and distribute heat. A boiler is a vessel that heats water and then pushes the steam or hot water through a system of pipes via radiators, baseboards, or underfloor radiant heating. A furnace forces heated air through ducts, which is why it’s sometimes called a “forced hot air” system. Keep in mind that replacing filters and cleaning ductwork on a regular basis preserves the air quality in your home or business and can extend the life of your system.
- Wide variety of fuels: oil, gas, pellet, and cord wood
- Zone heating: boilers let you heat only the rooms you want to
- Use existing ductwork: furnaces integrate with air conditioning
If your boiler or furnace has failed, contact your fuel provider immediately. You should also contact a qualified heating system contractor, particularly if your fuel provider does not offer replacement options. Not only will an expert repair or replace your system, they can also identify the cause of failure to help you avoid recurring problems. We provide rebates for efficient heating systems and low-interest financing to cover the cost of replacement.
- Contact your fuel provider and a qualified contractor immediately
- Ask for an energy-efficient option that meets your needs
- Get approved for low-cost financing within two business days
AFUEs and MMBTUs
Furnaces and boilers are rated by Annual Fuel Utilization Efficiency (AFUE), calculated by dividing how well a unit converts energy to heat by the amount of fossil fuel energy it consumes over the course of a heating season. A British Thermal Unit (BTU) is the amount of energy needed to heat one pound of water by one degree Fahrenheit. Heating is typically measured by dollar cost per million BTUs (MMBTUs).
- New units rate up to 95% AFUE, older units as low as 56%
- A typical home uses 60 to 100 MMBTUs per year
- Compare fuels by their cost per MMBTU: range from $15 for wood to $40 for oil
