Style and efficiency sums up the new Telford 8, it’s our most economical inset yet. It not only delivers an impressive 5-8 kw output but also achieves 75% efficiency burning wood. Installation couldn’t be simpler and there’s no air brick necessary. We’ve really put the Telford 8 through its paces in lab tests. DEFRA have recognised this with its stamp of approval meeting their stringent criteria for use in Smoke Control Areas. A bonus with all of this technical efficiency is the Telford 5 will happily provide heat right through the night until the following morning. The Telford Inset 8 is designed to fit a chair brick.
