Check out the Comfort-Aire HSW series geothermal heat pump perfect for radiant floors as well as general heating and cooling with an air handler. The HSW comes in 3.5 and 10 ton sizes to fit virtually every home. They heat and cool using hot water or chilled water and can be ordered with a generator for domestic hot water. A geothermal system uses the relatively stable temperatures of the earth for heat transfer, rather than creating energy by burning fossil fuels, saving you 30-60% on your monthly energy bill. The basic type of systems is the Closed Loop. A heat exchanger, typically polyethylene tubing, is buried in the ground or submerged in a pond or lake. A solution of water and antifreeze is pumped through the tubing. This solution transfers heat from the ground to the home in the winter, while indoor heat in the summer is transferred from the home to the ground or water.
The high efficiency scroll compressor is exceptionally quiet, but they have added a double isolation mounting system to minimize operating noise and insulation in the compressor compartment itself for further sound deadening. State of the art controls include onboard diagnostics and a “ feature that protects the unit by checking for: high pressure,
low pressure, high voltage, low voltage, loss of charge, condensate overflow, anti-short cycle, freeze protection for the coil. The system performance monitor, much like the “check engine” light on your vehicle, signals when it’s time for the filter to be changed and also if the system is not running at peak performance, allowing you to schedule maintenance before a lockout occurs. The HSW unit is so compact, they can be installed virtually anywhere indoors. Three panels can be removed for easy access for installation and maintenance.
What do we mean by “Energy Efficient”? You can judge efficiencies for yourself by comparing some industry standards. Cooling efficiency is measured by an Energy Efficiency Ratio (EER). The higher the number the more efficient the equipment. The geothermal units have EER ratings as high as 20.6, while traditional heat pumps are generally rated 10-15 EER. On the heating side, efficiency is shown by a coefficient of performance (COP) and the higher the number the better. The geothermal systems compare very favorably to traditional heat pumps. What this means to you and your customer is that while the initial installation cost of a geothermal system is higher than a traditional heat pump, you can quickly recoup these costs through energy savings. Contact your salesman for more information if you have a job which would lend itself to this type of system.
