Among heating and cooling systems available, the one that uses a water cooled heat pump is regarded as very efficient and economical. The system’s main principle uses water in transferring heat from source to destination with the least amount of energy.

It is also environmentally beneficial. It uses renewable energy heat sources and is basically pollution-free in its processes (supplying heat in winter and cooling indoors during summer).


There are two types of refrigeration technology today. One is air-to-air heat extraction, which takes the heat from the air in one place and transfers it someplace else. (Most of today’s air conditioners use this.)

Geothermal heat extraction, using a water cooled heat pump, gets the heat from the ground (or small water bodies) and transfers it to the places in need (houses and buildings). Both systems use pumps in moving air (air-to-air system) or water (water cooled system) in a heat exchange.

For water sourced heat pump systems, there is a boiler and water tower storage for adding or removing heat energy. This system also employs a water cooled heat pump. (Heat from the ground in geothermal extraction needs a compressor. However, there is no need to supply energy for a boiler or a water tower.)

Systems Loop types

Commonly called loop types because they use pipes in several loop configurations, these various cooling and heating systems use water cooled heat pump technology in transporting heat from the source (ground) to its destination (houses and buildings).

The horizontal straight loop has pipes installed under lawns below the frost line (around 5 feet underground). This popular type is best when the area is wooded or landscaped. Horizontal coiled loops (also called slinky” loops) have flattened overlapping coils and perfect for shorter trenches where longer horizontal loops cannot fit.

Vertical loops have pipes running straight down into the ground, ideal for small lots where space cannot accommodate any other type. They are usually utilized by commercial buildings where outside land space is premium.
