Good reasons to update your heating system

Many businesss 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 For most of these older systems, a significant share of energy and money go to waste every year due to outdated technology and an improperly sized system.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By replacing an outdated system with a gas-fired condensing boiler, a business owner may be able to save up to 30% on their annual heating bills, when using an outdoor reset control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.
