Hoval moves into the solar hot water business

Hoval’s SolKit is a highly efficient solar system for generating domestic hot water for commercial and residential applications. It comprises solar collectors with bracketry and flashing kits for on pitched roof, in-pitched roof, on flat roof or on the wall. The system also includes a stainless-steel cylinder, sophisticated plug-and-play digital-control system, pre-mixed heat-transfer fluid and all connections. A SolKit can be installed in a day using a flexible umbilical (15, 20 or 25 m) carrying flow and return pipes and a sensor cable. Designed with the University of Rapperswil, a European centre of excellence for solar equipment, SolKit uses Hoval’s LowFlow technology to achieve high solar-fluid temperatures, with minimal energy consumption for pumping. In contrast to other system, these high-temperature fluids are directed to the top of the cylinder whenever appropriate to provide solar-heated DHW at the taps without having to charge the whole cylinder, thereby reducing the use of auxiliary heating. A second coil can be served by a boiler. SolKits are available with a 250 l storage calorifier with two flat-plate solar collectors or a 470 l calorifier with two or three collectors. Each collector has a gross area of 2.4 m2 and a absorber surface area of 2.1 m2. These kits can be installed in vented and unvented DHW systems.
