Water Source Heat Pumps

Water Source Heat Pumps

Tandem Chillers Inc. manufactures water source heat pumps for cooling and heating in climates with moderate heating and cooling needs. Our water source heat pumps offer building owners an energy efficient alternative to furnaces and air conditioners. Like any typical refrigerator or air conditioner, a heat pump uses electricity to move heat from a cool space into a warm place. During the cooler part of the year, heat pumps move heat from the cool outdoors into your office or house. During the summer, heat pumps move heat from a cool building into the warmer outdoors. Because they move heat rather than generate it using non-renewable fuel, our heat pumps can provide up to 3x the amount of energy they consume.

How Water Source Heat Pumps Work

Like our chillers, a water source heat pump consists of a compressor and a heat exchanger that transfers heat from a body of cooler water to a circulating refrigerant that is piped into a building. If it is being used to heat a building, the refrigerant in the outside coils extracts heat from the air and evaporates into a gas. The indoor coils release heat from the refrigerant as it condenses back into a liquid. A reversing valve, near the compressor, can change the direction of the refrigerant flow for cooling as well as for defrosting the outdoor coils in winter.

Why Choose Our Water Source Heat Pumps?

Tandem Chillers designed its first modular chiller with a limited number of scroll compressor chillers and screw compressor chillers. With all the knowledge we gained over the 40+ years of process and modular chiller design, you can be assured that our heat pumps are also of a sound refrigeration design and easily serviced. Our design is unique from all other designs in so far as they can be removed for repair without shutting down the rest of the cooling or heating system. Our design makes so much sense that it is hard to see why our competition does not do it.
