Watermatic, electrolytic water treatment, limescale
The capabilities of Watermatic’s Kal-Guard+ water electrolytic water treatment to reduce the formation of limescale on heat-transfer surfaces have been used to benefit by companies such as Birds Eye, BMW, Whitbread, Asda and KrsipyCreme. Independent tests at Cranfield University have shown a reduction in limescale formation of up to 80%. Kal-Guard+ is a in-line powered water-treatment device that delivers a pro­portional release of zinc to manage limescale in a system. Sophisticated control that is simple to use matches the level of dosing to water conditions, producing a measurable residual effect throughout the system. The effects of limescale can be severe. For example a 1 mm layer of limescale raises energy costs by 7.5%. The effect of a 12 mm layer is to raise energy costs by 70%. Watermatic offers CPD seminars highlighting the potential savings to a wide range of businesses. The company’s web site (below) also has a payback calculator.

Timoleon underfloor heating

A specially designed Timoleon underfloor heating system has been incorporated into the sprung sports floor of a village hall near Totnes in Devon. Accidental damage to the underfloor heating that had served Harberton Parish Hall since it was built meant that a new system was required, but one tailored to the hall’s physical requirements. The semi-sprung floor is suitable for dancing and children’s games, and the hall provide a venue for community events from theatrical performances to weddings.
