The Envirogreen™ Oil Boiler

At Firebird, located in Cork, Ireland we are experts in innovation. We have developed the most efficient and most reliable home heating condensing oil boiler in Europe, which is also HVO ready. Although it meets environmental standards, this technology is expensive, leading to a high-priced oil boiler.

We therefore set ourselves a challenge to design an oil-fired condensing boiler that exceeded the NOx reduction requirements, offered the same outstanding level of performance, but most importantly remained an affordable option for our customers. After extensive research and development, in conjunction with European burner experts elco, the easy to install Envirogreen™ oil fired condensing boiler range was born. Our full range of oil boilers are also available in the UK.
