About Us

Trianco's history and pedigree can be traced back to the 1850s when Newton Chambers first made coal fire ranges at Thorncliffe in Sheffield under the name of Redfyre. Fireplaces, back boilers and free standing heating stoves followed and, in 1873, the company was awarded the royal warrant to the Queen Mother. The 1940s and 50s saw the company pioneer domestic oil fired boilers and it was amongst the first to launch an oil combi boiler. In the early 1970s they acquired Trianco Stewart, an oil boiler manufacturer, and thus Trianco Redfyre was born.

In 1995, the company became part of the Bullough Group and subsequently Union Investment (a merchant bank based in London). Now the Trianco portfolio is offered by TR Engineering who are backed by the Mountcity Group. TR Engineering is proud to be one of the last remaining British owned domestic boiler manufacturers.
