Bosch Greenstar Boilers Now Come With CRC200 Comfort Room Controller

All of the Bosch Greenstar Wall-Hung and Floor-Standing boilers now come with the CRC200 Comfort Room Controller.  The Wall-Hung Greenstar boilers used to come with the FW200 Weather Compensating Controller but that is now sold as an accessory.

The CRC200 is a programmable controller with an integrated temperature sensor and can be used as a boiler control or in conjunction with the CZM100 Comfort Zone Manager as a room controller. It comes with back light and features a time program for heating and indirect hot water tank.
The user interface is used to control a heating zone and a Domestic Hot Water (DHW) tank charging circuit for water heating directly at the heat source. The user interface displays information about the heat source and heating system and is used to change the settings.

A maximum of 8 heating zones is permitted when connected to several CZM100 Comfort Zone Managers. Water heating may be controlled with or without time program. Installation options: On the wall with a BUS connection to a heat source or CZM100 module with an EMS-BUS Interface (Energy Management System).

Please call Global Protankless Supply at 866-289-4652 for more information on the Bosch Greenstar boilers or accessories.

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.

    Special Reduced Pricing on the Bosch 450ESR NG (Natural Gas)

    Global Pro Tankless Supply is pleased to announce we have lowered the price on the Bosch 450ESR NG (Natural Gas) recirculating heater.  Please visit our website for more specifications and special pricing.  Please visit the downloads tab to view the specification sheet and installation manual.

    The Bosch 450 ESR NG is not approved or designed for closed loop heating applications.  The ESR unit is not a tankless heater as they have no flow switch to respond to flow.  Instead it’s a recirculating water heater designed for tank loading applications.  When an AquaStat (not included) hooked up to a tank tells the ESR that water needs to be brought back up to temperature, the ESR will tell a circulator (not included) to turn on to create flow through the heater to reheat the water in the tank.   Please refer to the installation and applications manual.

    The Bosch 450 ESR recirculating heater is a 120K BTU unit and can deliver 4.5 GPM at a 45 degree rise.  Efficiency is 81%

    The temperature control range can be set anywhere from 115°F (45°C) - 190°F (90°C)

    The Bosch ProTankless 450 ESR comes with a standard ¾” pressure relief valve.
