Gas Condensing Boilers

High-efficiency condensing technology from Viessmann offers optimum energy utilization, resulting in maximum savings for you.

Advanced condensing technology

A gas-fired condensing boiler is one of the most economical and clean ways to heat your home or commercial property, and it can reduce your monthly heating bills and environmental footprint. The Viessmann line of gas condensing boilers offers highly efficient and reliable residential and commercial heating solutions for your home or business.

Our comprehensive product portfolio lets you take energy savings a step further. Reduce your energy costs by integrating domestic hot water production with your 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 available from a single, trusted source, you don't have to compromise – total system performance and additional energy savings go hand-in-hand.

Good reasons to update your heating system

Many homes have heating systems that are 20 years of age or older. For most of these older systems, a significant share of energy and money go to waste every year due to outdated technology and an improperly sized system.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By replacing an outdated system with a gas-fired condensing boiler, a homeowner may be able to save up to 30% on their annual heating bills, when using an outdoor reset control with a proper heat loss calculation. In addition to significant cost savings, environmental savings with reduced CO₂ emissions can also be achieved.

Reliable and consistent performance

Stainless steel is the best choice for long-term reliability. That's why all of our condensing boilers are equipped with a stainless steel heat exchanger and burner. Developed and manufactured by Viessmann, these high-quality stainless steel components maximize performance and reliability. 

The stainless steel Inox-Radial heat exchanger comes standard on all Vitodens boilers.

How condensing technology helps you save

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 can achieve excellent efficiency of up to 98% by extracting the majority of the heat contained in the flue gases and converting it into additional heating energy. This helps you to save money and reduce your carbon footprint. 

To achieve this, Viessmann condensing boilers are equipped with corrosion-resistant, stainless steel heat exchangers, which cool the flue gases before they are routed into the chimney. By doing this, the water vapor contained within the gasses 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 energy consumption, but will also make an active contribution towards reducing your carbon footprint and protecting the environment.
