Bosch has just introduced a new Greenstar Combi 131 Gas-Fired Wall-Hung Condensing Boiler for space heating and DHW.  "Combi" (combination) unit with space heating and integrated water heating in one highly efficient, compact unit. With special insulation to ensure ultra quiet operation and the exclusive keypad safety lock feature to prevent unwanted tampering with heating controls, this unit is the ideal "green" upgrade for detached & terraced houses and is also suitable for apartments.

The Greenstar Combi 131 is simple to operate and some of the specifications include:

131.9K BTU

3" PVC concentric vent kit available for vertical or horizontal installation

Telescopic Concentric Up and out vent kit available for horizontal installation 

The energy-savings and environmental features are:

Aluminum-Silicon heat exchanger delivers high efficiency with low temperature applications

Low NOx emissions ahead of 2012 SCAQMD regulations

Simple, intelligent control options optimize efficiency and fuel consumption

Low electrical consumption when the boiler is in standby mode

Anti-cycle and modulation control

These Greenstar Combi 131 condensing space heating boiler can be used for either Natural Gas or Liquid Propane installations.   The Greenstar units come preset for Natural Gas (NG), but can be converted to Liquid Propane (LP).  A gas conversion kit is included.

The Greenstar Combi units come with a temperature control FW 200 that can either be mounted to the heater or mounted to the wall beside the heater.  This module allows the heater to be set for different temperatures, zones and the time of day the heater comes on and goes off.  The FW 200 control also comes with a temperature probe that goes to the outside and detects and monitors the outside temperature and then allows the heater to remember the coldest and warmest times of the day and year.

All Greenstar Combi boilers are equipped with a high-strength stainless steel secondary exchanger and burner with double passage - ensuring consistent temperature output based on demand. The DHW hot water temperature control limit of 140°F helps prevent scale build-up within the heat exchanger.
