Features

    The Bosch greenstar boiler brings today's high efficiency technologies together in a single package. Astounding efficiency ratings can be achieved with the use of Bosch's condensing technology, squeezing every last BTU out of your home's gas supply. An included 3-speed Grundfos pump and a wide variety of pipe venting options allow the boiler to be installed in nearly any home imaginable. This boiler includes a domestic hot water coil, allowing the boiler to act as a tankless hot water heater as well as a hydronic boiler.
  • Condensing Technology Improves Efficiency
  • The ZWB35-3 is a condensing boiler, using the leftover energy in the boiler's flue exhaust to further heat your home. Keep your home warmer for less energy cost!
  • Included DHW Coil
  • This Bosch greenstar boiler contains an internal domestic hot water coil. This allows the boiler to function as a tankless hot water heater as well as a hydronic water boiler.
  • Fully Modulating Fan
  • The boiler includes a fully modulating fan to control the boiler's burning rate, allowing optimum efficiency to be achieved during a wide variety of outdoor conditions.
  • Small Size and Low Installation Clearances
  • Low installation clearances on all sides, wall mounting configuration, and small footprint translate into a boiler that can be installed almost anywhere.
  • Included Boiler Control
  • Bosch Greenstar boilers include a CRC200 controller - a thermostat with an integrated temperature sensor plus programmable time schedules and energy saving functionality. An optional outdoor sensor (87472071010) allows for outdoor reset functionality.
