The Silver and Envirogreen™ Oil Boiler

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

We therefore set ourselves a challenge to design a condensing oil boiler for Northern Ireland 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 Silver and Envirogreen™ Irish manufactured condensing oil boiler, HVO ready range was born. Featuring cutting-edge burner technology this new range ticks every box.
