Envirogreen™ Heatpac

These Firebird HVO ready, oil boilers which are manufactured in Ireland are generally found in more traditional heating systems. Providing heat for radiators and separate hot water cylinders. They are installed as part of a system. Regular ‘heat only’ boilers can form part of a sealed system or open vent system.

This Firebird range of external boilers is similar in specification to their equivalent indoor models, 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.
