Hot Water Temperature Maintenance

Hot water temperature maintenance can be archived by the use of nVent RAYCHEM HWAT range of self-regulating heating cables that adjust their power output to compensate for variations in water and ambient temperatures. They replace supply-pipe heat losses at the point where the heat loss occurs, providing continuous, energy-efficient hot water temperature maintenance and eliminating the need for a recirculation system.

Installation of the HWAT system is simple. The heating cable can be cut to length, spliced, tee-branched, and terminated at the job site, reducing installation costs. Fewer plumbing components are needed; recirculation piping, pumps, and balancing valves are all eliminated. The HWAT system maintains hot water temperature continuously at every point along the supply pipe. Unlike conventional recirculation systems, they do not require overheating of supply water to allow for cooling. The HWAT system reduces the energy requirements of typical hot water systems with reduced heat loss from supply piping, no heat loss from recirculation piping and no pump to run.

The HWAT-ECO electronic controller provides flexible temperature control, energy savings, heat-up cycle function, BMS interface, and nine predefined programs that can be customized by the user.

BENEFITS

• Faster and more economical system to install than recirculation systems
• Overall reduction in running and maintenance costs
• Space saving
• Smart control
• Energy savings of up to 50%

We can either provide the heating cable and components only, which can be purchased directly form R&D or from our online shop, or we can offer a complete turnkey solution, which includes:

• The design and installation of the trace heating cable and components.
• The design and manufacture of the trace heating control panels.
• The design, and installation of all the power and control cables.
• The installation of all cable containment systems.
• Additionally, working with our thermal insulation partners, we can supply and install the thermal insulation.
