Frequently Asked Questions About Boilers in Gatineau and Ottawa
What is a boiler and how does it heat a home?
A boiler heats water that circulates through the heating system to deliver steady, even radiant heat. Unlike a furnace, it does not blow air, which limits the circulation of dust and allergens.
Do you install residential and commercial boilers in Gatineau and Ottawa?
Yes. Fernand Denis serves residents and businesses in Gatineau (Quebec), Ottawa and St-Isidore (Ontario). Dedicated teams in each region allow for fast local service.
Which boiler brands does Fernand Denis install?

The Navien combination boiler offered has a 95% AFUE rating and an output of 150,000 BTU. It runs on natural gas or propane.
What is the difference between a boiler and a furnace?
A furnace heats a home by blowing warm air through ducts, while a boiler does not blow air. It provides steady, even heat, quiet operation, and no regular filter changes. To compare with our gas and propane furnaces, the team assesses your building and your needs.
