BSRIA has launched a new test standard for heat interface units (HIUs).
An HIU is a packaged set of components that connects a consumer's heating and/or hot water system to a heat network such as district heating or a communical heat network, which operates in place of a boiler. Successful operation of an HIU depends on appropriate system design and specification followed by competent installation and maintenance.
The HIU test standard fills a gap in the UK market, according to BSRIA, providing the industry with a methodology to demonstrate the performance of HIUs and a means of product comparison across a range of thermal parameters. It also serves as a reference point for manufacturers, contractors and the end user.
The methodology within the standard can also be applied to chilled water HIUs used for space comfort cooling.
Colin Judd, senior test engineer at BSRIA, said: "We are delighted BSRIA was able to employ its knowledge and convert existing information into this test standard. We know such a standard will be extremely useful for members and industry alike. Indeed, we have seen significant growth in the testing of these products and they continue to increase in popularity."
The standard dovetails with BSRIA's recently launched HIU guide, which focuses on the issues surrounding the application and installation of both direct and indirect HIUs for residential and small commercial applications within district or communal heat networks.
