Does a Geothermal Heat Pump Really Generate Free Hot Water?

Geothermal heat pumps double as a free hot water source in both the summer and winter months in St. Louis, MO. Yet, as geothermal energy gains popularity in Missouri and southern Illinois, homeowners should make note of the following facts pertaining to this free source of hot water.

In order to make use of the wasted heat generated by a geothermal system’s compressor, a desuperheater captures that energy to treat and re-purpose the water.

Geothermal systems are excellent sources of free hot water, in humid cities such as Collinsville, Edwardsville, St. Louis City, Chesterfield and Ladue. During the summer, when the geothermal heat pump produces cool air, it can process most of a home’s hot water. In other words, a household can depend on most of its hot water supply during muggy times of the year.

In contrast, the geothermal pump does not provide the same volume of hot water over chillier periods of the year when the desuperheater does not have the capacity to acquire the type of surplus as created and reserved in the summer.

The cost of a geothermal heat pump depends on the size of the home and its distinctive heating and cooling specifications. This also influences the type of desuperheater compatible for the geothermal heat pump.

Yet even as geothermal heat pumps cool warm and generate hot water, size plays an integral facet of the purchasing decision. An oversized geothermal system costs more to install and maintain, while an undersized one does not have the capacity to heat and cool the home efficiently, impelling it to run more.
