Combustion Testing

The efficiency and safety of combustion appliances (water heaters, furnaces, boilers, gas stoves/ovens, fireplaces, etc.) varies tremendously depending on the site-specific conditions where the appliance is actually installed. 

Some appliances are designed to passively vent to the outside, some are power vented to the outside, and some are just...well...vented into the house. With the exception of a gas cooktop/stove, house-vented appliances are discouraged. These apliance emit harmful combustion byproducts directly into the house. 

The mixture of fuel and air is what determines how efficiently the combustion process happens. The speed at which the combusting gases move through the heat exchanger affects how much of this heat actually enters the house. If there is too much combustion air being pulled into the combustion chamber (very common), then both combustion efficiency and heat transfer efficiency drop dramatically. The average BRAND NEW high-efficiency furnace is under performing by 15%.

We'll test each combustion appliance in your home, documenting the flue-gas contents and drafting ability of each unit. With the results of this testing, adjustments can be made to ensure each appliance is operating safely and as efficiently as possible.
