Heating Systems

Carbon dioxide. Carbon dioxide is the primary end product of fossil heating fuel combustion. Too little carbon dioxide indicates incomplete combustion. For a heating oil burner, the CO2 concentration should measure between 10 and 12%. For gas heating systems, it should be between 7 and 9%. If an oxygen reading is taken instead, it should be between 3 and 6% for oil heating systems, or between 5 and 7% for gas heating systems.
Smoke
Smoke indicates lack of complete combustion and is usually not present in gas heating systems. On a scale of 0 to 10, the smoke number should be no higher than 1.
Carbon monoxide (gas heaters only)
Carbon monoxide indicates incomplete combustion and should be kept below one-tenth part per million (0.1 ppm) for safety reasons.
Draft
Correct draft promotes complete combustion and reduces net heat loss up the chimney. A pressure gauge measures the overtire draft through the combustion chamber, and the breach draft through the flue pipe. Overtire draft pressure should be between 0.01 and 0.02 inches of water, and breach draft should be between 0.02 and 0.04 inches higher than the overtire draft. If you have a sealed combustion or induced draft system (a fan pushing exhaust gases out), this is less important.
Cleaning Heating Systems
Heating parts to be cleaned include the heating burner (nozzle, electrodes, and filters), heating combustion chamber, heat exchanger surfaces, heating oil line filter, and flue pipe. (Oil nozzles and filters are often replaced rather than cleaned.) Sediment should be removed from the boiler and steam lines; corrosion inhibitors may be added to the boiler.
Heating Adjustments
Air and fuel flow adjustments will be made based on the results of the heating efficiency testing. The internal heating thermostat on the furnace or boiler (aqua stat or fan thermostat) should be calibrated to turn on and off at the appropriate temperatures.
Heating Pumps and Fans
Heating pumps and fans should be inspected and lubricated if necessary. You can reduce this heating loss by placing reflectors between the wall and the radiator. You can make reflectors from foil-covered cardboard, available from many building supply stores. The reflector should be the same size or slightly larger than the radiator. The foil should be periodically cleaned for maximum heat reflection.
Increasing the Heating System Efficiency
All these measures for boosting the efficiency of your furnace or boiler require a professional with the proper training and tools.
Reducing heating system size. If you have an older gas or oil heating system, and if you've added insulation, upgraded your windows, or tightened your house, chances are that your heating burner runs for only a fraction of the time, even in the coldest weather. Having your heating system constantly turn on and off is like driving in stop-and-go traffic you don't get very good mileage. A simple way to reduce this heating waste is by decreasing the rate at which oil or gas is fed into the heating burner. In some cases, however, generating of gas systems violates local building codes and voids manufacturers’ warranties. Check with your local code officials or knowledgeable contractors before proceeding.
