The Firebird Envirolite Boilerhouse CR35 is a floor standing, heat only oil fired condensing boiler designed for installation in a dedicated boilerhouse, garage, or outbuilding. It provides central heating for radiators and works with a separate hot water cylinder as part of a traditional heating system.
This oil boiler delivers a heating output of up to 35 kW and achieves an ErP A rating with an efficiency of approximately 92.6%. It uses a high performance Elco low NOx pressure jet burner and incorporates a patented heat exchanger design to maximise energy recovery. The unit is compatible with both sealed and open vent systems.
The boiler features a compact steel casing with full insulation to minimise heat loss, multiple tapping points for flexible pipework connections, and a built-in condensate trap. It is supplied with a two year parts and labour warranty and a five year heat exchanger guarantee when installed to Firebird standards.
- Heating output up to 35kW for larger systems
- Patented heat exchanger for improved energy efficiency
- Low NOx Elco burner meets current emission standards
- Four tapping points allow multi-directional pipe connections
- Dimensions: 684 mm (H) x 441 mm (W) x 381 mm (D) for compact installation
