  • External Regular Boilers C35

The Firebird ranges of external Regular Boilers are 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. The boilers are available in Standard and Slimline widths, and have removable sides for ease of access to any part of the unit. Piping can be carried out from the back or from underneath.
