Envirogreen™ Systempac

The Firebird HVO ready System oil boiler which is manufactured in Ireland is also referred to as a ‘sealed system boiler’, provides central heating and direct hot water via a storage cylinder, which is usually housed in an airing cupboard. Unlike a regular boiler heating system, there is no requirement to have water tanks situated in the loft. System boilers are generally easier to install, as the heating and hot water system components form an integral part of the boiler itself.

The Envirogreen Systempac is similar in specification to the internal Envirogreen System, with the addition of a built-in frost thermostat. There is no requirement to house the boiler in a building, so this option provides an ideal solution if internal space is at a premium.


  • High quality weather-proof PVC-coated casing.
  • Low pressure switch protects boiler in the unlikely event of system water loss.
  • Factory-fitted expansion vessel and circulating pump saves space and installation time.
  • Fully insulated to prevent heat loss. 
  • Patented heat exchanger design. 
  • Fitted with frost protection stat.
  • Ultra quiet operation.
  • Stainless steel terminal guard.
  • Flue can exit left or right.
  • High performance low NOx Elco burner.
  • Four models available in outputs from 12kW to 44kW.
