Green Water Heating


Many of the modern geothermal systems installed today are equipped with desuperheaters, which provide domestic hot water when the system is busy providing heat or air conditioning. A desuperheater is basically a small auxiliary heat-recovery system at the compressor outlet, using superheated gases from the heat pump’s compressor to heat water. The water then recirculates through a pipe to the home’s water heater tank. 

Green Water HeatingDuring the summer months, when the air conditioning runs frequently, the desuperheater can provide hot water virtually for free. During the winter months, however, it provides less hot water, and none during the spring and autumn months. When the geothermal heating system is be operating less effectively or not operating at all, the home’s conventional water heaters are used to meed household hot water needs.

A green home may be interpreted in many different ways, without a single, precise definition. Basically, a green home encompasses environmentally sustainable construction – i.e. the responsible use of natural resources – and minimizes the impact on the environment.

Green living is about much more than just energy conservation, it includes the impact on the environment, the site and location of the house, the material used for construction, the efficient use of water and its associated fixtures, the use of nontoxic and renewable material for decoration, the quality of indoor air, whether the project has a global impact, and so on.

From an inspection point of view, you are currently more likely to find an existing home that has been remodeled and enhanced to become “green” than a home that has been certified as a green home. Green living, however, is gaining momentum due to its energy savings, water conservation, solar system solutions and numerous renewable energy applications. Maybe not all people care so much about the environment, but everybody wants lower bills and green water heating for free.
