About Us

Sill-Line Perimeter Heating was originally part of the varied range of heating products of Myson Copperad operating from Wolverton near Milton Keynes. 20 years ago a separate company was formed exclusively for the manufacture of perimeter heating products and the business was moved to new facilities in Daventry.

Two years later the company acquired the Warmline Perimeter Heating business from Biddle Air Systems based in Nuneaton and in 2002 Sill-Line Perimeter Heating Ltd acquired the natural convector business of Lennox Industries.   At the same time the Daventry facilities were doubled in size. In 2006 the Spiral Wound Tubing business of Gunning Engineering was added to include heavy duty steel heat emitters in the already comprehensive range of natural convector heating products.

Sill-Line Perimeter Heating Ltd is the only UK Company to focus exclusively on the sales, production and development of perimeter wall mounted, pedestal and trench heating systems. The company is uniquely able to draw upon the great heritage of the product lines established by Myson, Biddle, Copperad and Lennox. We believe that our trench heating grilles are the best in the business. They are the result of over 20 years continuous development. They are truly fit and forget for an easy installation process.

Since commencing trading Sill-Line Perimeter Heating Ltd has supplied over 250 km of heating systems and is justly recognised as the leading specialist company in the sector. Wherever possible Sill-Line Perimeter Heating Ltd prides itself in offering a solution that meets the exact needs of each installation and where necessary provides a custom built product to meet individual design requirements.
