Geothermal

By utilizing energy from the earth, geothermal is an economical and eco-friendly heating and cooling solution. Our specialists have the knowledge and technology to help you install or integrate a geothermal solution into your process or application.

Over the past decade, there’s been rapid growth and adoption of geothermal heating and cooling. The interior ground temperature remains consistent throughout the year, which makes geothermal systems, reliable, eco-friendly, and a perfect heat source in winter, or heat sink in summer.

Geothermal systems operate with the use of heat pumps which use the ground as a heat source to provide warm water typically in the 105F to 120F range. There are numerous applications for indirect heating such as domestic water preheating, radiant floor heating and swimming pool heating.

    Due to the low water temperatures supplied from geothermal systems we typically recommend plate style heat exchangers in these applications. Plate heat exchangers offer the greatest efficiency and can operate with temperature differentials as low as 2 degrees Fahrenheit. AHRI certified heat exchangers, fitted with ALF pre-filters and stainless steel or titanium plates, are the recommended choice for corrosive flow media such as geothermal water.

    Valutech Inc has supplied heat exchangers for geothermal applications such as hot water and district heating for over 20 years. Our engineers have the knowledge, experience, and expertise to help fit your application with an efficient and economical geothermal solution.
