Today there are gas, electric, cast iron, condensing and modulating models that have an AFUE (annual fuel utilization efficiency) rating 85% or even more, thus achieving better efficiency with a whole bunch of improved features. AFUE is a parameter that is used for comparing and testing two different boilers under similar conditions. It is mainly based on a residential load profile, which differs from that of a commercial building. So, to the list of features belong:

  1. sealed combustion, which uses outside air in order to fuel the burner, thus improving safety and reducing draft
  2. electric ignition that eliminates the need of the pilot light burning all the time
  3. new combustion technologies, which extract a lot more heat from the same fuel amount

 

How Do They Work?

Modern residential boilers transmit the heat that is required to operate the heating systems and water heaters, offering relief from cold winter conditions. These models are usually used for the heating purposes in buildings and include the category I series boilers:

  • non-positive vent pressure appliances
  • non-condensing appliances
  •  incorporate natural draft appliances

High efficiency boiler residential is primarily characterized by clean combustion. Being meant for residential purposes, it is valued for longevity and economical operation. Such units are obtainable in many sizes in order to fit various types of residential heating loads. Besides, such heating systems are well-known for a pretty high degree of operational efficiencies that reaches up to 85% AFUE.

These two notions are always interconnected. The more efficient the boiler is, the less fuel is used. This means your energy bills get reduced. The maximum efficiency is reached during full load.

Residential boilers can be rated as AFUE or as per annual fuel utilization efficiency to reflect all losses in actual installations.

Environmental Protection Agency together with Department of Energy usually awards an Energy Star label to those boilers, which have an AFUE of 85 % and even more. Today there are high efficiency boilers residential that claim an AFUE of 97%. Buying them is your perfect chance to cut down energy bills and spend less money, having the same comfort in your house.
