Trane Air Handler AHU Electric Duct Heater - This Trane air handling unit photo shows a Trane AHU with electric duct heater above the Trane air handler in the supply duct. In places where natural gas is not available and propane LP gas is impractical or not wanted. Electric heat makes a good source for heating. This electric duct heater is situated in the supply side of the air handler. Furthermore, many duct heaters are installed inside the air handler. (more…)
HVAC Reznor Heating System | LP Gas Unit Heater
HVAC Reznor Heating System LP Propane Gas Unit Heater – this Reznor unit heater provides heating for warehouses, garages, and other open spaces which can be heated with unit heaters. Unit heaters are ideal for big open areas which need heating without duct work being used to channel the air into the space. Sometimes these unit heaters are also used in mechanical rooms for protection of the other HVAC equipment and piping to prevent freezing conditions inside the mechanical rooms. The unit heater can be quickly installed and put into service in only a few hours once electrical service and gas service is provided in the location where the unit heater will be located. This unit heater is located in a remote camp site where electricity is available but natural gas was not available. LP or Liquefied Propane is trucked in to fill large LP Propane tanks located near the buildings which use these unit heaters to produce heat. A propane piping system and a series of propane gas regulators were installed and these unit heaters utilize the propane in the tanks being fed by this piping system. The regulators reduce the pressure from the tank to a usable pressure for the unit heater. (more…)
These evaporators serve a large complex where natural gas is unavailable. The complex needed a fuel for boilers for heating and domestic hot water so these evaporators were installed to along with two very large LP tanks to handle the heating needs of the complex. As a liquid propane (LP) has a specific weight of .504 (where water is 1) and propane vapor has a specific gravity of 1.5 (where air is 1) making propane vapor 1.5 times heavier than air. (more…)
Natural Gas Versus Propane | HVAC Heating Fuels - What is the best for you when choosing between either natural gas or propane? Do you get natural gas or propane for your heating system fuel supply? In some cases you will not have a choice between natural gas or propane. Since having natural gas supplied to your home or business will require a natural gas pipeline near your home or business. If there is a pipeline near your home and you do not have a meter you can call the gas company. Most of the time they will install the meter next to your home for no cost. However, it is always good to ask if they are going to charge you for installing a meter for use in your residence or business. (more…)
Standing Pilot Gas Valve Propane Heating | HVAC Heating - How It Works. The standing pilot gas furnace uses a standing pilot to light the main burners. Many gas-fired water heaters have the standing pilot ignition system. The standing pilot gas ignition system is often referred to as a safety pilot because it increases the safety. Safety of ensuring the main burners are lit. The standing pilot can be used on a natural gas ignition system or an LP ignition system. These heating ignition systems are older and are slowly being replaced by the more modern and safer electronic ignition systems.
Outside All Weather Boiler - Outside all weather boilers are used in circumstances where it is not possible to install the boiler inside a mechanical room or anywhere in the building. There some considerations one needs to take into account about having an outdoor boiler especially if it is for a residential application. (more…)
Gas Furnace Facts - Gas Furnaces are the most used types of heating appliance for our homes and businesses and modern gas furnaces range in efficiency ratings from 79% to 98%. Gas furnaces can either use propane or natural gas for fuel. This largely depends on whether natural gas is available at the location where the appliance is located. Propane is used in rural areas and in urban areas where the natural gas pipeline infrastructure has not been installed. Natural gas is delivered via pipeline while propane is delivered via trucks and pumped into tanks. Tanks are located on the premises where the gas furnace is located. The gas furnace that utilizes the propane for fuel.
Gas Furnace Components | HVAC Heating Systems. There are different types of gas furnaces which are available for purchase today and the older models which were installed many years ago still in operation. The older models were typically atmospheric type gas furnaces and used a lot of gas to produce heat much of which went up the flue because efficiencies were low. The standing pilot atmospheric type gas furnaces still exist today but they are slowly going the way of the dinosaur as they are being replaced by newer more efficient furnaces. (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.
