In line with our focus on energy efficiency, Multistack offers various water-cooled and air-cooled heating solutions. Traditional heat pumps are ideal for summer cooling and winter heating applications with a geothermal ground loop. Dedicated heat recovery modules are compact, flexible, and efficient – and have the added benefit of being able to provide simultaneous heating and cooling without reversing valves. DHRC can be used in a variety of applications such as domestic hot water, VAV reheat, and many more building heating needs. With a COP 4 or more times higher than a boiler, the DHRC provides unmatched efficiency. Want to maximize the efficiency of your system? Utilize our VME II or air-cooled ARA product lines to provide simultaneous heating and cooling. These unique designs provide simultaneous heating and cooling variable loads for a complete building solution.
