Condensing Boilers vs. Non-Condensing Boilers

While condensing boilers have been on sale for several years now; their benefits have only been highlighted in the recent past. With the need for energy conservation, manufacturers have abandoned the old-fashioned, conventional boilers for the new condensing commercial boilers.

For customers intending to buy or replace their boilers, it is critical to know what a condensing boiler is, and its advantages over a non-condensing boiler.

Condensing boilerHere are the unique differences between condensing and non-condensing boilers.

  1. Condensing boilers have several, large heat exchangers while non-condensing boilers use a single combustion unit and only one heat exchanger.
  2. Condensing boilers burn combustion products at low temperatures of around 55 degrees Celsius while non-condensing boilers require high temperatures-around 180 degree Celsius to burn combustion materials.
  3. Condensing boilers are energy-efficient and require a high initial investment, but cost less to maintain while non-condensing boilers have a high carbon print, are cheap to buy, but costly to maintain the venting in the long-run.
  4. With their new technology and increased energy-efficiency, condensing boilers are the right choice for all of your heating needs.

Here are the top advantages of condensing boilers:

  1. No Heat Loss: While all new boilers are condensing boilers, their predecessors were non-condensing heat-only and combi boilers that had heat leakage in the form of gases. The selling point of a condensing boiler is its capacity to capture energy loss and uses the gases released to heat the water going back from your central heating system.
  2. Safety: Heating systems are high-energy machinery, and your safety should come first. Condensing boilers shine in the aspect of safety because they have a negligible risk of sucking materials into the boiler.
  3. Increased energy efficiency: The introduction of condensing boilers into the market stems from their power efficiency capacity. They have a 25 percent better energy efficiency in comparison non-condensing boilers. Their efficiency is realised through the use of waste to preheat the cold water going into the boiler.
  4. Proper Insulation and dispose of waste substances: With traditional, non-condensing boilers the risk of materials being pulled into the boiler is commonplace. However, condensing boilers are designed in a way that provides proper heat insulation to capture air from outside to reduce the chances of objects being sucked into the heating system. Besides, condensing boilers use a pipe to dispose of toxic substances through the drainage system, which helps to avoid the operator from being intoxicated by waste substances.

Choosing between a condensing boiler and non-condensing boiler is a no-brainer once you heed the advantages and the differences presented here.
