The Space-Ray SWH series of LPHW heaters can heat any area comfortably in combination with central heating systems.

The SWH system can be fed via a boiler or any other warm water system. The SWH-LT range is suitable for use with heat pumps.

The SWH heat exchanger consists of a combination of copper pipes and fins made from high quality fibre reinforced synthetic material.

An SWH-EC version allows control of the supply air fan by a stepless 0-10V control as well as providing approx. 25% electricity savings over the standard SWH.

SWH-LT models are fitted with EC fans as standard, and offer the ability to work in cooling mode when connected to a heat pump.
