Product details
nVent RAYCHEM HWAT-R heating cable is designed to maintain hot water at a desired temperature within the buildings distribution system. Ideal for use within hotels, hospitals and convalescent homes HWAT-R can prevent legionella growth and eliminate the need for recirculation within the hot water system.
HWAT-R: Features & Benefits
- Instant hot water: improved delivery of hot water compared to recirculation systems
- Prevention of bacteria proliferation: maintain a specific water temperature, LEGIONELLA prevention capability
- Efficient: energy saving, reduced water use
- Simple to design: self-regulating flexible cable, cut to length
- Low installed cost: no need for return pipes, recirculation pumps, balancing valves or complex commissioning
- Control: advanced control and monitoring to maximum energy savings
- Reliable: 10 year warranty
