Definition Of Water To Water Geothermal Heat Pump

Water to water geothermal heat pumps are a type of ground-source or hydronic heating and cooling system that uses the earth’s constant temperature as a thermal energy source.

They essentially transfer heat from one body of water (such as an aquifer) to another for heating and cooling purposes. This process is far more efficient than air conditioning units or traditional HVAC systems since water can transfer 200 times more heat than air, making it ideal for geothermal applications.

Water to water geothermal heat pumps use ground loop technology, where two sets of pipes are drilled into the ground around a home connected to each other by a well, one set acts as an intake line while the other is used as an exhaust pipe so that warm air from outside can be cooled when necessary during summer months.

The main components include circulation pump, compressor/condenser unit, secondary pump control motor and expansion valve which together help move hot or cold air in different directions depending on weather conditions.

Working Principle Of Water To Water Geothermal Heat Pump

Water to Water Geothermal Heat Pump (GHP) is a type of system which utilizes the energy found within the earth’s subsurface to heat and cool buildings.

This technology works like traditional heat pumps, but instead of relying on ambient air temperatures, GHP systems take advantage of earth’s constant temperature to make heating and cooling more efficient.

A water-to-water geothermal system uses an open loop configuration in which it draws ground water from one source to another creating a pressure differential between its intake point and its discharge pipe.

The warmth or coldness extracted from the groundwater depends on the temperature of the aquifer it was taken from, typically warmer than in summer months due to natural solar warming effect under populated areas with high surface population density conditions known as “urban heat island effect”.

Once this warm or cold water is brought back by circulating pump into house through closed loop circuit, it is then injected into side medium in order to turn colder at winter when transitioning outside air temperatures are lower than room temperatures or vice versa. 

Since water transfers efficiently 200 times better than air, it makes geothermal heat Exchanges significantly much easier compared other varieties such as traditional forced air ducting methods including common HVAC installations.

Benefits And Efficiency Of Water To Water Geothermal Heat Pump

Water to water geothermal heat pumps provide great savings compared to traditional HVAC systems and air source heat pumps. By utilizing the consistent temperature of the ground in an open-loop system, this type of pump provides energy efficiency far greater than more conventional technology can provide.

Geothermal energy is considered a renewable resource that serves heating and cooling needs, reducing dependence on traditional fossil fuels while lowering associated environmental impact.

Water to water heat pumps use 25% to 50% less electricity than their HVAC counterparts can and are also virtually maintenance free, a major cost saving for home owners or business owners alike.
