The Envirogreen™ & Envirolite™ Oil Boilers

At Firebird, located in Plymouth in the UK, we are no strangers to innovation, having developed the most efficient domestic condensing oil boiler in Europe, which is also HVO ready. Whilst meeting all the environmental criteria, the downside to this particular type of technology is the cost, resulting in a premium priced oil boiler.

We therefore set ourselves a challenge to design an condensing oil boiler that exceeded the NOx reduction requirements, offered the same outstanding level of performance, but most importantly remained an affordable option for our customers. Following an extensive research and development programme, in conjunction with European burner experts elco, the Envirogreen™ and Envirolite™ HVO ready, condensing oil boiler range was born.

Most Efficient Oil Boilers

Featuring cutting-edge burner technology this new range of Irish manufactured, HVO ready condensing oil fired boilers ticks every box.
