Oil Controls Burner - The oil burner and oil controls provide the main source of heat for this oil furnace. The oil burner comprises an oil pump, an oil pump, a burner electric motor, a burner blower, a step-up transformer, an oil ignition control, an oil burner gun, and an oil nozzle (inside not viewable here).
The burner electric motor is directly linked to the blower and the oil pump and when the electric motor starts (controlled by the ignition control) the pump begins pumping oil while the blower provides primary air to the combustion chamber. (more…)
Natural Gas Properties and Furnace Heating Efficiency - Natural Gas is a popular fuel used for heating systems in America and other countries. If we look at the properties of natural gas and the heating efficiency of natural gas furnaces we will see that natural gas furnaces lose efficiency because of what is contained in natural gas as it is delivered to your home for consumption by your natural gas furnace.
Natural gas in its raw form coming straight from the ground needs to be refined to remove impurities that should not be contained in natural gas. As you read below you will see that in the refining process moisture is removed from the natural gas however during the refining process some of the moisture in the natural gas remains and therefore this affects the efficiency of your natural gas furnace.

Boiler Combustion Efficiency | HVAC Heating Systems - It is important to understand that a commercial application (can also apply to residential boiler applications) is going to consume a large amount of the energy budget, therefore it is important to track efficiency ratings because a slight drop in the efficiency can cause a sharp increase in the energy costs.

Determine That You Actually Have a Standing Pilot Gas System
Check to Make Sure You Have Fuel
Understand the Valve Function
Light the Pilot Light
Enjoy the Warmth
How To Light a Pilot Light – Standing pilot gas furnaces and water heaters are still around today even in newer homes. All the major hardware stores and HVAC dealers carry standing pilot appliances. Although a new standing pilot gas furnace or boiler is rare finds these days. Because of the move to higher efficiency models and the wide use of electronic ignition technology which improves efficiency.
Before you proceed you’ll want to determine if you actually have a standing pilot system in your HVAC furnace, boiler, or water heater.
In many cases, on many appliances, there are basic instructions on lighting it, in fact, you do have a standing pilot system. Check around the main panel or look at the gas valve itself. Sometimes, especially on older appliances, there are no instructions on it if the pilot light goes out on a standing pilot gas furnace, boiler, or water heater.
The label or sticker on the furnace, boiler, or water heater faded a long time ago and you will need to follow the instructions in this article. (more…)
Gas Furnace is Making Too Much Noise - Richard, my gas furnace makes a lot of noise when it is running and it is somewhat annoying and sometimes bothers me when I am sleeping. It is installed in a closet close to my bedroom. What can I do to fix this gas furnace that is making too much noise? I’m growing to hate my noisy gas furnace. Jenny
Jenny, sorry to hear about the noise your gas furnace is making. I know an overly noisy gas furnace can be irritating. All gas furnaces make some noise when operating and we can break it down into three different noises. Depending on which noise your furnace is making will depend on a fix to your furnace making too much noise. (more…)
Oil Furnace Condensation Problems - This Oil Furnace has flue gas condensation problems as one can see from the white residue forming on the front of this oil furnace. This problem occurs when the flue gases are not hot enough to rise above and out of the flue. (more…)
HVAC Tip - A thermocouple is commonly used in standing pilot gas furnaces and water heaters are technically referred to as a copple element and produces millivolts when heat is applied to the tip. This millivoltage is necessary to keep the pilot valve inside the gas valve open. If the pilot flame goes out, the thermocouple stops generating millivolts. Without the millivolts, the valve closes thus preventing gas from escaping when there is no flame. Thermocouples fail because of oxidation. It is recommended that you keep the pilot lit throughout the year to prevent excess oxidation. The thermocouple can be found in many different types of gas furnaces, gas logs, and gas water heaters.
