• 112.50 Kb HIU Engineering Change Process V2 Engineering change is a necessary process for manufacturers and can be bought about because of a supply issues, quality issues, as well as ratio or product improvement. For heat interface units tested under the BESA HIU test regime, it is imperative to maintain consumer confidence in the test results by ensuring that any change will not adversely affect the performance of the HIU. This version applies to any HIU's holding either a 2018 or 2023 test.

• 2.22 MB Water Treatment and Conditioning of Commercial Heating Systems Guide This guide was started because the commercial boiler manufacturers raised the issue of poor water treatment and conditioning in commercial heating systems, which in turn caused problems with the appliance and ancillary components. The guide has been written from the boiler and heating system point of view and, as is evident from the acknowledgements, many of the leading commercial boiler manufacturers have had their input into writing this guide.
