Our Products

At the beginning of 2015, and following almost a quarter of a century of successful growth, Sill-Line Perimeter heating Ltd. relocated to its current, state of the art manufacturing facility, based in Daventry. Founded in 1992, and following the successful acquisition of the perimeter heating business of Copperad from Myson RCM the company then acquired the Warmline Perimeter Heating business from Biddle Air Systems two years later.

In 2002 Sill-Line Perimeter Heating Ltd further acquired the natural convector business of Lennox Industries and during this period of rapid growth the original Daventry facilities were doubled in size. In 2006 to compliment its rapidly expanding natural convection businesses, Sill-Line Perimeter Heating Ltd acquired the Spiral Wound Tubing business of Gunning Engineering, which added heavy duty steel heat emitters to its
already comprehensive range of commercial products.

Sill-Line Perimeter Heating Ltd is unique in its UK business model by focussing exclusively on the sales, production and development of British made perimeter wall mounted and trench heating systems. The company is able to draw upon a great heritage of product lines established by the likes of Myson, Biddle, Copperad and Lennox, providing over 100 years of design experience within the present workforce.

Since commencing trading as Sill-Line Perimeter Heating Ltd has supplied hundredsof kilometres of heating systems and is justly proud of its position as a leading high-quality company in this specialist sector. Sill-Line Perimeter Heating Ltd prides itself in being able to offer bespoke solutions that meet and exceed our clients specific and individual design requirements.
