Water to Water


NextEnergy's new Tranquility R410A water-to-water (THW)™ series high temperature heat pump provides almost unlimited applications for hydronic heating systems due to the high temperature output (140°F), internal controls, and factory-installed options. The THW series includes a special high temperature scroll compressor coupled with heat exchangers designed specifically for water heating, which results in unmatched efficiencies and performance.

The new "Euro" look allows the THW™ heat pump to be cosmetically integrated with our full line of Tranquility heat pumps and storage tanks. Additionally, each unit is run-tested to ensure optimum performance.

The Tranquility TMW™ Water-to-Water series offers high efficiency and high capacity with advanced features, quiet operation and application flexibility at competitive prices. The TMW series can be used for a variety of hot water applications, the most common being radiant floor heating. Radiant floor heating is the ultimate in comfort and practicality. It reduces fluctuations in temperature, resulting in a more comfortable home environment. The TMW can also provide a large portion of your home's domestic hot water heating needs.


A Tranquility TMW Water-to-Water series can be packaged with our Tranquility Forced Air series to provide you with a true, on demand, "triple function" solution for all your home heating, cooling and hot water needs. The efficiencies and capacities of a geothermal system increase dramatically when the functions of both Tranquility systems are combined.
