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.
