This Greenstar 79 condensing space heating boiler can be used for either Natural Gas or Liquid Propane installations.   The heater comes preset for Natural Gas (NG), but can be converted to Liquid Propane (LP).  A gas conversion kit is included.

The Greenstar boiler comes 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.

The Greenstar condensing space heating boiler is specifically designed for space heating only but can also be used for Domestic Hot Water (DHW) when it is piped to an indirect tank and using a pump, aquastat and check valves.
