What Is a Water Source Heat Pump?

The standard heat pump for a home is also known as an air-source heat pump. It uses the air outside a home as its medium for heat exchange, absorbing heat from outdoors in heating mode, and releasing heat to the outdoors in cooling mode. Another type of heat pump that has gained popularity is the geothermal model, i.e. the ground-source heat pump, which absorbs and releases heat using loops buried in the ground.

There is a third type of heat pump that isn’t as well-known as the others, but which may be the ideal one for you: the water-source heat pump. They need particular situations to work, but if your home fits the specifications, then you should investigate water source heat pumps in Savannah, GA as way to keep your home comfortable all year long.

How water-source heat pumps works

Water-source heat pumps operate in a way similar to geothermal models: they circulate refrigerant from an indoor cabinet to the outside through a series of loops that access a more stable warm temperature than what is in the air. But the loops of a water source heat pump are placed down in a nearby body of water, rather than buried in trenches in the ground.

Although you may think of water as being much cooler than the air, and therefore not a good source for drawing heat for heating mode, the depth at which the loops are sunk in the water has the same stable temperature found down in ground. They work even in cold winters if the lake/pond/river freezes over, since the water at the lower level remains unfrozen and available for heat exchange.

Water-source heat pumps are efficient, safe, and easier to repair than geothermal loop systems since they require no digging to reach. They can work either as closed-loop systems, which circulate an anti-freeze solution for refrigerant, or as open-loop systems, which attach to the water lin and continually circulate water for refrigerant. An installer will be able to tell which type will work best for a home.

The major limitation of water-source heat pumps is that, obviously, they need to have a deep enough body of water nearby. If your home is located in the vicinity of a river, lake, or a deep enough pond, then a water-source heat pump is a great possibility you should discuss with an installers.
