Envirogreen™ System

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.
