When people talk about heat pumps, they don’t often realize that there are 3 type of heat pumps: air source, which is the most common type, ground source, which is used with ground loop geothermal systems, and water-source, which is used with a water-based geothermal systems. Heat pumps work by transferring heat from one location to another, which is why the different elements of ground, air and water can be used: they all contain heat. So how does a water-source heat pump work? Let’s take a look.
When the sun heats the Earth, the ground and water bodies absorb this heat. While the heat disappears from the surface when the sun goes does, it doesn’t disappear from these elements when you go below the frost line. Water-source heat pumps are part of geothermal systems that harness this latent heat from bodies of water – but it isn’t the water itself that circulates through the water loop or heat pump, it’s environmentally-friendly, heat absorbing anti-freeze. This solution absorbs heat from the surrounding water and transfers it to the water-source heat pump. In the heat pump the heat is concentrated and then dispersed to your home’s living spaces.
The types of geothermal systems that use a water-source heat pump are:
- Pond/lake (closed loop)
- Well water/surface body water (open loop)
Benefits of Using a Water Source Heat Pump
There are a number of benefits homeowners can gain from using a heat pump. First, a heat pump system can provide both heating and cooling, so you can have all of your HVAC needs satisfied with one system instead of two separate ones. A second benefit is the energy efficiency: heat pumps do not use fossil fuels at all. Instead, a small amount of electricity is used to power the appliance. A third important benefit is the lifespan: heat pumps last an average of 20-25 years versus independent heating and cooling systems, which usually last 15-20 years.
