Reasons to Use High Efficiency Condensing Boilers

High efficiency condensing boilers use the latent heat of the water that is produced by fuel burning as a supplement to sensible heat (energy exchanged via a thermodynamic system).  The use of both energy sources makes high efficiency condensing boilers more efficient in contrast with conventional units.  There are substantial reasons to use high efficiency condensing boilers in both residential and commercial buildings.

High Efficiency Condensing Boilers are More Efficient than Conventional Designs

A thermal efficiency of up to 99% can be achieved by condensing boilers.  Conventional boilers are far less efficient at only 70-80% (due to the higher heating value of the fuels).  It is not uncommon for basic models of high efficiency condensing boilers to have an efficiency rating of at least 90%, qualifying them in the highest energy efficiency categories possible.

Energy Efficiency Ratings for High Efficiency Condensing Boilers in the USA and UK

High efficiency condensing boilers are often rated with Energy Star Certification or Eco Logo in the USA.  They also rate well in the UK, often awarded a Seasonal Efficiency of Domestic Boilers (SEDBUK) “Band A” rating for efficiency.

High Efficiency Condensing Boilers are More Environmentally Friendly

A high efficiency condensing boiler emits 90% less carbon dioxide (CO) than a conventional unit.  They also release 80% less nitrogen oxide (NOx).  By using high efficiency condensing boilers, you are also cutting greenhouse gas emissions and fuel consumption by around 59%.  Very little heat loss occurs, which is why the best high efficiency condensing boilers can even operate at up to 99% efficiency.
