DS439 is unavailable in English, despite being referred to in UK guidance, however the above graph is derived from DS439 based on a peak property load of 37.6kW. For larger HIUs (see below) coincidence factors are commonly applied to peak HIU output (incorrectly in the opinion of many, including ourselves). Overlapped Diversity.

DS439 is a Danish standard which has been endorsed by CIBSE in CP1 and is widely used for heat network design. These standards tend to deal with the level of diversity or coincidental hot water load in terms of its peak instantaneous usage.

The following graph shows the energy requirements for various numbers of homes, and various diversity curves. These include: DS439 - Danish Code of Practice SDHA F101 - Swedish District Association REDAN - Danfoss Redan COHEAT - Using EST (Energy Saving Trust) Data Scaling Diversity to Peak Dwelling Load

For this example we choose the 37.6 kW as in the Danish DS439 table. Schematics, drawings and example figures do not constitute an actual design, and each project should be reviewed individually as a unique design process.

Figure 1:The Guru Pinpoint diversity curve shows that following DS439 may still result in oversized systems, especially when you consider the Danish curve is for domestic hot water only, while the Guru curve is for all loads.

Den tidligere udgave af normen for vandinstallationer DS 439 blev i 2018 delvist skrevet ud af Bygningsreglementet, fordi den var forældet. Normen er nu blevet gennemrevideret, og fremstår i en helt ny form og med rigtig meget nyt og revideret indhold. På kurset lærer du mere om de ændringer, der er til normen for vandinstallationer.

Current guidance refers to the Danish Standard DS439 when it comes to the calculation of diversity factors, and there is a chart that can be used. But when systems differ from the precise 38.5kW used in the Danish standards, there is a process referred to …
