Hot Water Temperature Maintenance

Large commercial buildings need a way to provide hot water at the tap in the most energy efficient way, without long waits or wasting water. Pentair Thermal Management has a sophisticated domestic hot water temperature maintenance (HWAT) system that provides immediate hot water at the tap that is a nice alternative to a recirculation system.

Whereas, a recirculation system:
  • Requires that you keep the water heater temperature in the system at least five degrees above the maintain temperature to compensate for the heat that is lost in the recirculation loop. 
  • Requires return lines, pumps, and balancing valves as part of the system. 

Pentair Thermal Management hot water temperature maintenance (HWAT) system provides a simple, reliable alternative to recirculation in commercial buildings. The HWAT system:
  • Maintains the water at a uniform temperature along the entire length of the supply pipe. Thus, it is unnecessary to heat the water above the maintain temperature. 
  • Includes HWAT heat trace cables that can be installed up to the fixture, which mean that you get hot water faster and waste less water.

HWAT is a fully integrated system that includes:

  • Electric heat trace cables – the HWAT-Y2 and HWAT-R2 heat trace cables adjust their power output along the entire length of the pipe to compensate for variations in water temperature and ambient temperature. These cables are designed for installation on hot water supply pipes underneath standard pipe insulation. 
  • Connection kits and accessories – items for making electrical connections and properly completing the installation, such as power connection and end seal kits. 
  • Advanced control systems – electronic controllers that monitor and/or control the desired temperature maintenance of the pipes. 

The HWAT-ECO and ACCS-30 electronic temperature controllers optimize the energy efficiency of the HWAT system by controlling the pipe temperature with either HWAT heat trace cable. The temperature set point can be programmed on a 24/7 schedule to suit the specific job requirements, providing the maximum water temperature control and energy savings to the end user.

The Benefits Of Geothermal

Geothermal technology harnesses the Earth’s renewable thermal energy stored just below the surface or in large bodies of water for the purposes of providing forced air heating and cooling, hot and chilled water and dehumidification. The system exchanges the natural heating and cooling properties of the Earth between a building and the ground. This transfer of energy is the source of enhanced performance and environmental superiority as Geothermal systems employ a small amount of electrical energy to capture, move and concentrate a large amount of “free energy” provided by the Earth. The result is the utmost in space conditioning.

Ground source heat pumps are the most commonly applied geothermal system today for both residential and commercial applications. They take the natural heating and cooling properties of the Earth to create "free energy" for a given space. The beautiful thing for end users is that only a small amount of electrical energy is needed to capture, move and concentrate this energy.

Heat-Gard Non-Electric Radiator Thermostats Keep a Heating System Comfort Balanced

Non-electric thermostats have been successfully used throughout the world for years. They're proven to be the most simple, reliable way to prevent energy waste and reduce heating costs. At the same time, they ensure individual room comfort. They sense changes in temperature and automatically increase the flow of heat in response to a temperature drop or automatically decrease it in response to temperature rise.

Short Payback Time
Because Heat-Gard is non-electric, it is relatively inexpensive to install and operate. A low cost Heat-Gard on every radiator is the most reliable way to update an old heat guzzling system economically.

Easy To Service
The Heat-Gard valve is made so the complete cartridge can be replaced without draining the system, by use of a special inline cartridge changer. This is a great advantage for hospitals, schools and nursing homes where disruptions of a heating system can be tremendous problems. For large public building and schools, there is even a vandal resistant Heat-Gard to prevent unwarranted tampering with the heat settings.

Backed By Taco's Hydronic Experience
As with all Taco products, Heat-Gard is pretested at the factory before it ships. Their exacting quality standards have given all their products a reputation for dependability and top performance.
