Old boilers are not energy efficient and can consume massive amounts of energy each month.  To maximize your energy savings, be sure to look at purchasing only high efficiency boilers.  By replacing an old boiler with a new high efficiency boiler, you can help conserve our natural resources and save money at the same time.

When selecting a new high efficiency condensing boiler, look at the AFUE, or the annual fuel utilization efficiency.  Old boilers can be in the 55-65% range, while the new standard is a minimum of 80%.  Newer boilers are even as high as 95% and higher.  This should be the most important factor in selecting a new boiler.  Electric boilers have a 100% AFUE, but consume a large amount of electricity and can be costly.  They are only good for when you will only need to use it occasionally.

Before shopping for a new boiler, measure the size of the space you will need to heat. A boiler unit that is too large for the area can also waste fuel and, therefore, cause high gas bills.  You should also be sure your home is well insulated so you can select a smaller boiler unit and save even more money on the investment and utility bills. Without proper insulation the energy savings from a new boiler won't be as high.

A professional should assess your situation and make a recommendation.  Wall vented high efficiency boilers are also an option.  These are more expensive than other boilers, but the energy savings make them worth the initial investment.

A professional contractor will be able to help you choose the right boiler for your needs. Don't let the initial cost of a new boiler hold you back from purchasing one.  The monthly fuel savings will allow the boiler to pay for itself in just a short time.

High Efficiency and condensing boilers not only save money in the operating costs, they can eliminate the use of old unrepairable chimneys that the old boiler may be using to direct the fumes outside.
