2015 NAECA Standards for Gas & Electric Residential Tankless Water Heaters

The U.S. Department of Energy has increased the energy factor requirements for residential water heaters effective April 16th, 2015 through the National Appliance Energy Conservation Act (NAECA). This update of regulations will affect all manufacturers selling residential water heaters in the U.S. Residential water heaters include storage type units that store heated water in an insulated tank and instantaneous type units that heat water on demand.

These standards do not apply to electric water heaters under 20 gallons or instantaneous electric water heaters 2 gallons and above.
If you have questions or concerns about specifying or installing Bosch residential tankless water heaters, please contact your local Bosch Sales Representative or call Customer Support at 1-866-642-3198

New Bosch Hydronic Air Handler

Global ProTankless Supply is pleased to announce that we are now selling the new Bosch Air Handler Systems.  These systems are designed to be used in conjunction with the Bosch Greentherm C1050ES & C950ES units.  The new Bosch Hydronic Air Handler can replace furnaces with a ducted system, eliminating the need for a gas pipe, venting, and fresh air in-take required for furnaces. The new air handler has an integrated control board that connects to the home’s thermostat. When the thermostat calls for heat, the air handler will turn on the integrated pump immediately and turn on the fan 30 seconds later to allow the heat exchanger to preheat. When the thermostat calls for cooling, the control board will only activate the blower.

The air handler connects seamlessly with tankless water heaters, transferring the highly efficient water heater’s hot water through a hydronic heating coil within the air handler. As the hot water circulates through the coil, warm air is sent through the residential duct system as the cool water by-product recirculates to the tankless unit to be reheated and reused.
The air handler is available in two models, AHU 50 and AHU 70, which can be sized with most CFM and BTU output ratings to suit a range of home sizes.

The Bosch Hydronic Air Handler is designed to work efficiently with the ENERGY STAR rated Bosch Greentherm tankless water heater to provide a complete solution for home heat and domestic hot water.

The hydronic air handler can also be used with A/C systems - a compatible A/C coil can be placed on top of the hydronic air handler and the blower inside of the hydronic air handler turns ON when the thermostat calls for cooling.

For further information and to purchase a Bosch Air Handler please call Global ProTankless Supply at 866-289-4652.

Z-Flex Z-DENS Polypropylene Rigged & Flexible Venting Material

Global Protankless Supply is pleased to announce we are now carrying the Z-Flex, Z-DENS polypropylene venting.  Polypropylene (PP) is comprised of only 2 elements carbon & hydrogen and is made without the use of any toxic or carcinogenic materials, heavy metals or chlorides. PP has a higher maximum flue gas temperature limit (230°F) as compared to PVC (149°F) & CPVC
(194°F). PP is easily 100% recyclable where PVC & CPVC is not due to its chemical composition and various additives. Recent developments in flue systems for use with high efficiency heating appliances, combined with the increased familiarity of use and installer confidence in polypropylene venting systems, has led to the development and continuous improvement of the polypropylene Z-DENS system.
Designed and Tested Safe
Unlike most PVC and CPVC pipe:


  • Z-DENS is specifically designed, tested and listed as a vent system. 
  • Z-DENS is manufactured from environmentally safe and sustainable fire retardant polypropylene, offering superior performance. 
  • Z-DENS does not require explosive or toxic cleaners, primers or cements; eliminating the safety and health concerns associated with these products. 
  • Z-DENS Self-Sealing design does not require any curing time, significantly reducing installation times and allows immediate system start up
  • Z-DENS can be used to vent appliances in New York City where PVC is NOT PERMITTED.


  • Z-DENS is available in diameters 2” (60 mm), 3” (80 mm), 4” (110 mm), 5” (125 mm), 6” (160 mm) and 8” (200 mm). Z-DENS is also fully compatible with Z-DENS FLEXIBLE and Z-DENS CONCENTRIC making for a complete and safe flue gas system.
