Natural gas furnaces and boilers
Residential and commercial options

furnaceNatural gas is known for being an efficient, reliable fuel for heating homes and businesses. Heating with natural gas offers:

  1. Reliable comfort
  2. Lower operating costs
  3. Environmental benefits

Whether you are working on a residential or commercial project, there are many options available.

Residential furnaces and boilers

Learn facts and information about natural gas furnaces in our residential Energy Efficient Appliances section. If your customers are deciding between a standard or high efficiency furnace, use the convenient furnace efficiency calculator to help them estimate how much they might save each month.

Compare operating costs between a natural gas or electric water heater, or standard vs. high efficiency.

Commercial HVAC options

Installing energy-efficient, natural gas heating, cooling and ventilation equipment is a good way to cut down on energy bills. There are many options, so choose the one that's right for your customer's business:

 

  • Conventional boilers are space heaters that use natural gas to supply heat by using either low-pressure steam or hot water. Heat is circulated through the building by a system of pipes. Energy efficient boilers can feature pulse combustion, high turn down burners, economizers, vent dampers and other energy saving features.
  • Conventional furnaces are forced air space heaters. Furnaces circulate air across a heat exchanger with a blower or a fan and distribute the heated air throughout the building using a series of ducts. Energy efficient furnaces can feature a secondary heat exchanger, electronic ignition, sealed combustion and pulse combustion.
  • Conventional unit heaters are also forced air space heaters. Unit heaters are typically used in warehouses, garages or manufacturing facilities. They are normally ceiling mounted, and discharge the air directly into the space. Standard units have pilots and are gravity vented. Energy efficient units feature electronic ignition and power venting.
  • Radiant heaters or infrared heaters, are typically used in warehouses and garages, and in drafty locations where doors are opened frequently. Infrared systems heat the objects, the floor and people beneath heating units.
  • Absorption chillers are designed to reduce your operating and maintenance costs for cooling while eliminating CFC (chlorofluorocarbon) refrigerants. Absorbers use water as the refrigerant, completely eliminating the need for CFCs, which are known to damage the ozone layer of our atmosphere. Absorption chillers have few moving parts, so operation is quiet and vibration-free.
  • Engine-driven chillers are an energy-efficient and cost-effective technology for cooling commercial and industrial facilities. Natural gas engine-driven chillers have the ability to vary the speed of the engine to match the load, resulting in high part load efficiency. Heat recovered from the engine can be used for heating domestic water or for other thermal applications.
  • Desiccant dehumidification equipment. Desiccants reduce the ambient moisture in the air, making it more comfortable and easier to cool. They also have the ability to reduce the amount of airborne bacteria and fungus. Desiccants increase your comfort while reducing your operating costs by separating the latent (moisture-related) from the sensible (temperature-related) cooling load. Conventional air conditioning equipment controls temperature only, and may supercool the air below the dew point to condense excess moisture. This is expensive to operate and often results in a cold, clammy environment.
