Radiant Floor Heating

Radiant floor heating is considered by many to be the most comfortable means of heating a home or building. We’ve supplied exchangers for radiant floors with heat loads ranging from 25,000 to 2 million Btu/hr.

Radiant floor systems circulate warm water through a series of tubes which radiate the heat to the home or building. In many cases these systems are isolated from the heat source using a brazed plate heat exchanger. This is an extremely comfortable method of heating a home or building.

Radiant floor systems are quiet, energy-efficient and can help prevent dust and other allergens circulating and being blown through the air. The heat exchangers for these systems are small and lightweight which is critical in environments where space is limited and thoroughly planned out.
