Condensing Boilers : Key Facts [Infographic]

An Opportunity for Savings

Automatic Heating presents an infographic on the potential savings available to Australia’s commercial sector through the use of superior high efficiency condensing boiler technology as compared to conventional boilers.

According to studies by Pitt & Sherry, the proportion of the total gas used that produces heating and hot water as opposed to food production and other uses is 65% for office buildings and 49% for the hotel sector. Substantial savings could be made by the application of increased efficiency in the generation of heating and hot water.

Condensing Boilers – The Proven Performers

By recovering the heat normally lost in the flue gases, condensing boilers push efficiency levels into the high nineties. When conventional boilers convert gas into thermal energy by combustion, the byproducts are released into the atmosphere via the flue. Condensing boilers improve efficiency by collecting residual heat from the flue exhaust and reusing it to preheat the cold water feed.

Comparing Technologies

If we measure boiler efficiencies using gross calorific values conventional boilers typically reach values of 80-83% at full load. By contrast, a condensing boiler can reach figures as high as 98% efficiency at full load under the same conditions.

Out in the Field

In the real world, these figures have been proven by monitoring how Modulex boilers have performed in the field. Since replacing conventional boilers in February 2013, the Crowne Plaza Hotel in Melbourne has achieved a 31% saving on natural gas consumption per guest per night. Overall the installation of Modulex Condensing Boilers has produced an average monthly saving of 25% on natural gas expenditure.

Return Water Temperature is Key

The lower the return water temperatures, the greater the boiler efficiency.

Comparison.

In summary, with conventional boilers, 20 cents in every dollar is lost to the flue whereas condensing boilers lose only 2c.

Percentage.

Automatic Heating recommends condensing boilers as end-of-life replacements for conventional equivalents in the following applications.

  • Commercial Office Buildings.
  • Hotels.
  • Shopping and Retail Centers.
  • End-of-trip Facilities.
  • Leisure, Health, and Fitness Centres.
  • Aquatic Centers.
  • Wholesale Markets.
