Wood and Gas Furnaces FAQ’s

Discover everything you need to know about wood and gas furnaces in our comprehensive FAQ section, providing answers to common questions and valuable insights into heating your home efficiently.

A variable speed furnace blower adjusts its speed based on the gas burner’s heat setting, ramping up or down to optimize temperature and prevent cold air circulation. It also adjusts for airflow resistance, like from a dirty air filter, ensuring efficient heat circulation.

The two-stage heating system operates more efficiently by starting at a lower firing rate and only switching to a higher rate if needed, resulting in longer running times and more evenly distributed temperatures throughout the home compared to conventional furnaces. This approach ensures a more consistent and comfortable room temperature by minimizing temperature stratification.

Choosing the right furnace size involves considering square footage, insulation, window construction, and sun exposure to gauge potential heat loss. Consulting with an expert or a Napoleon HVAC dealer, who can evaluate these factors and consider your current furnace’s BTU and efficiency, is the best approach to determine your needs.

A wood furnace can operate during a power outage without damage, similar in design to a wood stove. Although its efficiency decreases without the distribution blower, gravity can still circulate hot air through the ductwork, keeping the house warm enough to be livable.
