Harnitek Fan Coil Radiators work with a significantly lower water temperature than a traditional radiator. This means that the demands on your heat pump or boiler are significantly lower which helps to increase their lifespan of operation. The integrated fan allows for much greater airflow and can generate heating on demand substantially quicker than traditional radiators. In warmer summer months, a key benefit of the Harnitek Fan Coil is that it works in reverse to provide cooling. This helps to avoid the use of expensive and inefficient fans or air conditioning systems. With only 35 degrees of water flow temperature versus 55-60 degrees for traditional district radiators, the Harnitek Fan Coil is super-efficient.
