Condensing vs Non-Condensing Boilers

When searching for a new boiler to replace your existing one, be sure the boiler you choose for your home provides you with greater efficiency and better features.  Understanding the difference between a condensing and a non-condensing boiler will help you choose the most energy-efficient heating system for your home.

So, what's the difference?

Condensing boilers are usually fuelled by gas or oil. They efficiently heat your home and are thought to be far more secure. Non-condensing boilers, commonly known as open vent boilers, draw air from the room. A non-condensing boiler features a single heat exchange component through which all hot gases pass to heat the water contained within the exchanger's walls. Both of these types of systems have different venting requirements.

Let's take a closer look at some of the biggest differences between the two...

Condensing Boilers

  • This requires the use of one or a large heat exchanger.
  • The temperature of combustion products is usually lower, between 50 to 55 degrees.  
  • The condensing heat exchanger recycles exhaust gas. 
  • Effective in tackling climate change by dramatically lowering CO2 emissions. 
  • Although they have a higher initial cost, they are more cost-effective in the long run.

Non-Condensing Boilers

  • It requires a single combustion chamber, as well as a heat exchanger, is required
  • Significantly less expensive to install, allowing you to save lots during the installation process.
  • Maintaining and repairing it is less expensive and could save you a lot more money in the long run when compared to condensing boilers.
  • Very easy to install
