Gecko have experienced an increased trend in water to water heat pump installations. We are currently working on 5 sites using either river water or lake water as our energy source. The great advantage of a water/water system is that the efficiency of the heat pump is improved, by as much as 20%, as the energy source is usually at a higher temperature than a ground based system, and the energy source – the water- is constantly replenished. A water/water system using Pond Lake or River water also has the advantage that it eliminates either drilling costs and disruption, or the need for a ground array with the disruption of ground works that this causes.
