Learn About Boilers & Chillers

Here’s a quick look at what boilers and chillers are:

  • BoilerA boiler is a heating system that can be installed in a home, office, commercial building, warehouse, barn, or anywhere else that has access to a fuel source. Boilers use heated or vaporized fluid (typically water or glycol) to generate and distribute heat. A boiler can either distribute steam from room to room via pipes and steam radiators or move hot water through baseboard radiators or radiant heating systems. Boiler systems can also heat the air directly with a coil. A boiler can be powered by natural gas, oil, or propane to heat up the water or glycol.
  • ChillerA chiller is a cooling system that cools air by circulating a liquid (usually water) that has been cooled by a refrigerant. These appliances can be installed in homes, buildings, factories, and connected to appliances like equipment, refrigerators, and other cooling devices. Chillers remove heat by circulating a heat-absorbing refrigerant through vapor-compression. The cooled liquid is then distributed through pipes in a home or building, and coils in an air handler, through units that dehumidify the air. 

How Boilers & Chillers Improve Comfort in Commercial Properties

Your commercial property needs a specialized heating and cooling system that is customized to the building layout, size, use, and age. A commercial boiler and chiller is a great option for heating and cooling a commercial property of any size. A commercial chiller is a device that uses water or glycol to remove heat from an area. It draws heat into it and then exhausts the heat outside. A boiler heats water or glycol up and transfers the heat through the air handlers and vents. Boiler and chiller systems are much more efficient than other heating and cooling systems. They don’t need to run as long to improve the temperature in the building, and so they use less energy and cost less money to operate. The distribution of heat from a boiler is also much more even than other heating systems. They are also very cost-effective–with proper care and maintenance, boilers and chillers can operate safely and efficiently for decades before needing replacement.
