How It Works

Condensing boilers use a fuel source, such as natural gas, to heat water for space or water heating. During this process, heat is extracted from exhausted flue gases. This lowers the temperature of the flue gases below 60°C. As a result, the gases condense to liquid form, which releases latent heat that can be captured and used to reheat the return water.

It's the re-use of latent heat, which otherwise would be exhausted with a conventional boiler, that saves energy and improves efficiency

Maintenance

To make sure a condensing boiler will be the right fit for your building, consult an HVAC or engineering consultant who can evaluate suitability, savings, and how to improve your heating system for ideal condensing conditions.

To ensure your condensing boiler is operating at optimal efficiency, ask your installer to determine maintenance guidelines for your building requirements. It is important to make sure your facilities personnel are properly trained for routine maintenance, as well as scheduling a tune-up every two years from your service provider.

Benefits

  • Achieve up to 98 percent thermal efficiency compared to 70-85 percent thermal efficiency for new conventional boilers
  • Lower operating costs and fewer emissions
  • Reduces chimney repairs and maintenance costs
  • Contemporary designs come in compact sizes for space efficiency

Building Applications

A condensing boiler is typically an ideal heating solution for any commercial or industrial building. Be sure to check with an HVAC or engineering consultant to ensure that your current heating system is able to return low temperature water (less than 60°C) and that proper ventilation and drainage is possible.
