These boilers 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 an 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.
