How Does a Water Source Heat Pump Work?

A water source heat pump, as the name implies, is a heating or cooling system that uses natural water resources as the source of power for maintaining temperatures inside your home. You can use a water source heat pump around water bodies such as a lake, well, river, or pond.

A WSHP can either be a closed-loop or an open-loop system. The type of system will depend on several factors such as the availability of water, quality of water, and any local regulations that may affect the installation. In a closed-loop system, the heat pump circulates the same water to regulate the temperatures in your home. A closed-loop heat pump is usually attached to a water source such as a lake, a large pond, or a well. The pipes are filled with an anti-freeze liquid, which never comes into direct contact with water. The liquid when travels through the pipe gains or loses heat depending on the mode the heat pump is working in.

An open-loop heat pump is usually installed in rivers or other water bodies with suitable geological conditions for the WSHP to work effectively. In an open-loop system, the heat pump draws water directly from the water source and circulates through the system to maintain temperatures in your home.

During the heating mode, the refrigerant is transformed into a gas through evaporation, which allows it to absorb heat from the water source. The compressor compresses the gas raising its temperature and pressure, which when circulated into the home via the blower fan, releases heat. In cooling mode, the heat pump works the other way around, releasing heat into the water, and cooling the inside of your home.

The heating and cooling modes of a WSHP can be controlled through a thermostat inside your home. The thermostat turns on the heat pump according to the mode you’ve selected and heats or cools your home to the set temperature.

There are several options of heat pumps you have from which you can choose, like water source heat pumps. There are several advantages and disadvantages to installing a water source heat pump. However, when a high investment is in question, you always want to weigh the options and consider if it is the right choice for your home.
