Case Study

Installing blue flame boilers

Grant VortexBlue condensing oil boilers have the same qualities as their Vortex counterpart models but with the added benefit of greener credentials. With their cleaner burners, blue flame boilers provide heating engineers with a solution to fit efficient oil boilers with significantly lower NOx emissions within their customers’ homes.

Blue flame burner technology is very sophisticated but there are plenty of familiar features that installers will recognise. To help heating engineers better their understanding of blue flame oil boiler technology, Grant has shared a blog that covers this topic in detail.
