Solar Heating Systems

The D'MAND Kontrols® System Works with Solar Heating Systems for Homes and Businesses

Whether you have an integral collector-storage system, indirect circulation system, direct circulation system, flat-plate collector, evacuated-tube solar collector, vented system or unvented hot water system, the D'MAND Kontrols® System will work with all commercial and residential solar heating systems to provide you with incredibly fast hot water at a fraction of the energy and water waste of traditional water systems.

In order for the D'MAND Kontrols® System to work properly, it needs a source of hot water and a source of cool water that feeds into the source of the hot water. In other words, the cold water that runs to your kitchen plumbing, bathroom plumbing, etc. must also run to your water heater. As long as your commercial or home solar heating system’s pump is powerful enough to create sufficient flow (at least 1/2 gallon of water per minute) it will work with the D'MAND Kontrols® Hot Water System.

The D'MAND Kontrols® System has many, many benefits, including:
