Good reasons to update your heating system with highly-efficient gas condensing technology

There are many homes in Canada with heating systems that are 20 years of age or older. For most of them, a significant share of energy and money go to waste unnecessarily every year due to outdated technology and an improperly sized system. Along with wasting energy, these boilers contribute to climate change by needlessly releasing harmful CO2 emissions.

Save money and reduce emissions

By replacing an outdated system with a gas-fired condensing boiler, a homeowner can save as much as 30%* on their annual heating bills. This not only results in significant cost savings, but also environmental savings with reduced CO2 emissions.

It doesn't stop there

Our extensive product portfolio lets you take energy savings a step further. Reduce your energy costs by integrating domestic hot water production with your heating boiler, and manage the entire system with one of our control solutions. Or put the sun to work for you by adding a solar thermal package. With the entire system from one source, you don't have to compromise: total system performance and additional energy savings go hand-in-hand.

Condensing technology for maximum efficiency

How to save with condensing technology

Condensing technology not only utilizes the heat from the combustion of gas, but also the unused heat that would escape up the chimney with a conventional heating system. Condensing boilers achieve excellent efficiency by extracting almost all of the heat contained in the flue gases and converting it into additional heating energy.

To do this, Viessmann condensing boilers are equipped with a corrosion-resistant, stainless steel Inox-Radial heat exchanger, which cools the flue gases before they are routed into the chimney. By doing this, the water vapor contained within the gases is deliberately condensed, and the additional heat released is transferred into the heating system.

By choosing a condensing boiler, you will not only benefit from reduced monthly bills, but will also make an active contribution towards protecting the climate and the environment.
