Consider updating your heating equipment
One way to help offset the rising cost of energy and significantly reduce heating costs is to replace your aging heating equipment with a new high-efficiency unit. Mass Save incentives can shrink the cost difference between a run-of-the-mill replacement and a high-efficiency one. Also you may be eligible for extra incentives if your furnace is at least 12 years old or your boiler is at least 30 years old. With rebates and interest-free loans from Mass Save, you might find the whole project is less costly than you think.
Mass Save always offers incentives for the purchase of high efficiency heating equipment. You may also be eligible for 0% financing through the Mass Save HEAT Loan Program. The HEAT Loan Program provides customers the opportunity to apply for a 0% interest loan from participating lenders to assist with the installation of qualified energy efficient improvements in their homes. If you meet eligibility requirements and receive lender approval, you may receive a 0% interest loan of $500 to $25,000 for energy saving upgrades, such as a new furnace or boiler, and repaid over 2–7 years. Also, for a limited time, the cap on HEAT Loans has been increased to $50,000!
In order to qualify for a HEAT Loan, you must have a no-cost Mass Save site visit to confirm the efficiency on your current system. You can schedule that appointment by calling 866-527-SAVE (7283). You can also start the process by filling out a short questionnaire about your home or apartment: Click here for National Grid or here for Eversource.
During you visit, your Energy Specialist will evaluate your equipment and determine eligibility. If your existing equipment is determined to be eligible for a HEAT Loan, you will receive a HEAT Loan Intake Form. Once you have estimates for a replacement system, you can take the HEAT Loan Intake Form and the estimate to a participating bank.
Heating oil members, perform regular system tune-ups to make your heating system run more smoothly, and if it's time to purchase a new heating system, we recommend choosing a system that is Energy Star rated.
We encourage those who are considering installing solar electricity or solar hot water systems to make sure they are already using energy efficient lighting and appliances, and low-flow faucets so they can get the most out of their solar energy investment.
And we encourage everyone to install energy efficient lighting and appliances so that they can invest their savings into the purchase of green electricity. Customers can reduce the additional cost for New England GreenStart or New England Wind by implementing cost-saving energy efficiency measures in their homes, such as those described below.
Why make your home more energy efficient?
- Lower Energy Bills! Much of the energy we pay for is wasted. The average household can cut its energy bills by 10-50% through a few inexpensive energy-efficient measures.
- Less Pollution! The burning of fossil fuels causes global warming and poor air quality. Furthermore, the extraction and transport of coal and oil result in harmful environmental impacts.
- Energy Independence! Our dependence on foreign oil leads to geopolitical conflicts.
- More Comfort! You can eliminate drafts, make your energy systems more responsive to your needs, and avoid unhealthy moisture problems by looking at how your house functions as an integrated energy system.
Why are your energy bills so high?
Some of the biggest sources of energy inefficiency in the home are
- Leaky windows and doors (this doesn't mean you need to replace them! Try air sealing.)
- Un-insulated roofs and exterior walls
- Old, inefficient appliances, particularly heating systems, refrigerators and air conditioners
- Incandescent and halogen lighting
- Leaving lights, computers, and other appliances on unnecessarily
- Heat is turned up too high or air conditioning is turned too low
