We can help you make the decision that keeps your home warm and your money in your pocket. Here are the ways that can help you choose the right boiler:

Choose the best heating contractor

Choosing a reputable HVAC contractor to install your new boiler can be as important as the boiler itself. You should request quotes from at least 3 heating contractors to ensure that you receive a range of bids.

Choose the best boiler

FurnaceCompare can save you money in the following ways:

  • Dollar for dollar, a high efficiency boiler will provide you with more heat than a low efficiency boiler. However, this does not necessarily mean that you should buy the most efficient boiler on the market. That decision depends on many factors — for example: whether you use gas or oil, how well your house is insulated, and your climate. FurnaceCompare has the most comprehensive efficiency data available. However, we do more than this — we provide you with detailed instructions on how to compare apples to apples when comparing boilers. We will help you make the efficiency choice that will save you money month after month.
  • Did you know that an over-sized boiler (one which produces too much heat relative to the size of your house) is much more expensive to run than a correctly sized boiler? Using our data and the load calculation provided by your HVAC contractor, you can compare the capacities of different furnaces, to make sure you are buying the right sized furnace.

Payback period for high efficiency

Payback period is the time it takes for the unit to recover its purchase, installation, and operating costs. The shorter the payback period is, the higher the boiler’s efficiency. To find out which unit will be most cost-effective for you, compare the initial costs of the boiler and the annual energy costs you incur.

For example, say a high-efficiency boiler costs $4,000 and the lowest efficiency model costs $2,000. Now find out the annual energy cost of each boiler. The EnerGuide label on your boiler will tell you what its annual energy cost is. For example, if the difference is $300, it means the high-efficiency boiler will save you $300 a year on fuel costs. Payback period can be calculated by dividing $2,000 (the difference in price between the two boilers) by the annual energy cost difference of $300 = 6.7 years. So an energy savings of $300/year will offset the extra cost of a high-efficiency boiler in 6.7 years. When you take annual savings into account, don.t forget to factor in rising fuel prices.

Understand how the HVAC market works

Have you purchased a boiler before? Is it customary for HVAC contractors to charge for a load calculation? The answer is: “No”, as long as that load calculation is performed as part of a bid to replace your boiler.

Should you contact the manufacturer if something goes wrong with your furnace after it is installed? In general, your first step when something goes wrong should be to call the contractor that installed the boiler. If they can’t (or won’t) help, the manufacturer would be your next step. Be sure to understand your HVAC Warranty.

Find rebates for your high-efficiency boiler

Hundreds of governmental and commercial entities around the United States and Canada offer rebates to consumers for purchasing a high-efficiency furnace.
