Geothermal FAQ: What Are the Advantages of Installing a Water Source Heat Pump

If you have a body of water on your property and are looking to boost energy efficiency in your Spokane home with a geothermal heating and cooling system, consider installing a water-source heat pump system. Like other heat pumps, such as air-source or other geothermal models, water-source heat pumps transfer energy rather than consume fuel to create it.

Water source heat pumps pull this energy from water, and the more constant temperature at the depth they are submerged at can make them more effective than air-source models, as air is much more susceptible to temperature fluctuations. If a water source heat pump system sounds like a heating option you may be interested for your home, call the geothermal specialists at ACI Northwest today. We’ll make sure that you get the best system for your personal needs.

There are two basic types of water-source heat pumps. You can choose either an open or closed loop system. Both are effective, but the water source on your property will ultimately determine which is best for your Spokane area home. We can answer any questions you have about water-source heat pump loop systems, so don’t hesitate to call with questions.

A closed loop system is generally more expensive but does not actually use any of the water from your water source. A coil is installed beneath the water, and this closed loop acts as a heat exchanger. An antifreeze solution circulates throughout the loop system and heat is absorbed from the water. This heat can then be used in your home. When it is warm out a water-source heat pump can be reversed, dumping excess heat from your home back to the water source.

An open loop system does not make use of an antifreeze solution. Rather, the water from the source on your property is used itself to absorb and circulate heat. It is pumped through a heat exchanger and at the end of the cycle is simply dumped back to the source. There are certain requirements necessary for this type of installation, as well as a closed loop system, and permits may be required. Be sure to work with a qualified professional to ensure that everything is done according to code.
