Combustion Analysis and combustion safety are one of the main focal points in the energy audit. Many times homeowners are unaware that they have problems with their combustion equipment (e.g. furnace, water heater, clothes dryer and gas stove). These items have not been serviced on a routine basis and these items require make up air to operate efficiently and safely.
We use state of the art combustion analysis equipment. We analyze the combustion flue gas on the furnace and water heater along with checking carbon monoxide levels in the stove and oven (gas stoves). This analysis allows us to test and check the following items:
- Oxygen Mixture
- Carbon Monoxide levels
- Equipment Efficiency
- Flue Gas Draft
These tests allow us to determine a course of action based on the test results. We strictly follows the standards outlined by the Building Performance Institute (B.P.I.).
We perform “The Worst Case Draft Test” as recommended by BPI. This test includes putting your “Combustion Appliance Zone” (CAZ) in the worst case setup to determine if all of your combustion appliances will operate safely in the worst case scenario. (This test is performed by running your combustion appliances and by turning on exhaust fans, dryer and air handler to make sure that your combustion appliances do not back draft under worst case conditions.) If this test fails then recommendations are made before any energy efficient retrofits can be performed.
These tests are also conducted again after all work is completed. A Home that has been air sealed “Too-Tight” can create potential problems for the homeowner; A BPI Certified Professional Building Analyst is trained to address all of these potential problems.
This “Testing In” and “Testing Out” is the only kind of energy audit that should be conducted on your home. Testing after the work is complete assures that your home is in safe working condition and verifies the performance of installed measures.
Combustion Analysis is one piece of the diagnostic puzzle used to gather information on your home to determine the most cost effective and safest plan of action to make your home more energy efficient.
