VDI 6036 The new guideline for mounting radiators

VDI 6036. A significant step forward in terms of safety and reliability.

In the event of personal or material damage, all associated companies and people can be sued in some way. To provide the participants with better legal security, the Association of German Engineers (VDI) drew up guideline VDI 6036 for mounting radiators. It aims to support planners and heating engineers when calculating possible additional loads on radiators to ensure maximum future reliability and safety.

Innovative fixing technology, which fully meets the requirements of VDI 6036.

Kermi has oriented their fixing programme towards high load-bearing capacity, optimal stability, and maximum security. Completely constructed in your own house - with the know-how that comes from
decades of specialist experience. Conforms precisely with the standard VDI 6036. With the risk of misuse taken in account and therefore more reassuring certainty for planners and heating engineers.

Lasting stability – an indispensable prerequisite for appropriate safety in real use.

Radiators are exposed to physical contact on a daily basis. In the home, at work, in schools, train stations, airports, foyers. . . Therefore, misuse is generally the rule in real cases. Often through negligence or even deliberate misuse. From individuals harmlessly leaning on the upper edge of the radiator and children sitting on or climbing up the radiator, to the high load associated with masses of people leaving at the end of an event or even during fire alarms. In extreme cases, the radiator can come loose and cause damage due to its heavy weight. The severity of the hazard depends largely on the design, load capacity, rigidity, and reliability of the radiator fixing.

VDI 6030 The new heat

Good reasons for modernisation

Perceptibly more convenience and comfort:

No comfort deficits any more, such as e.g. cold radiation and cold down draughts.

New design and modern optics:

The range of modern radiator models offers virtually unlimited interior design options with multifunctional use.

Safe and durable:

Modern radiators offer new quality and safety & security.

Efficient, healthy and hygienic:

Apart from savings, low energy technology offers a healthy dose of cosiness due to balanced thermal comfort.

Value increase for the property:

Modernisation with new radiators leads to a value increase, particularly for old houses.

VDI 3805

The VDI 3805 sets out the data structure of product data across the entire TGA and therefore not only gives software users via the manufacturers access to current product data in the area of technical product properties, but also the geometric presentation in CAD programmes.

Spending on radiators

Sheet 1 (October 2011) = Product data exchange in TGA basic principles
Sheet 6 (May 2004) = Product data exchange in TGA radiators

Since the early 90's, Kermi has been working on the BDH or VDI directive work in association with standardisation of the product master data. With the introduction of the BDH radiator data sets, manufacturers and planners can make clear savings in project work and can improve the quality of tenders. Within the framework of the triumphant advance of the CAD-based planning, the BDH data set was replaced by the VDI 3805 data format. Kermi took a leading role in the development of this modern data guideline. Today in the plumbing and HVAC environment, there are more than 20 VDI 3805 data sheets for different groups of products ( ).

VDI 3805 allows plumbing and HVAC manufacturers in different trades to make product data available in high quality for a number of software applications quickly and without bureaucracy. This means the planners always have up-to-date data available in their software for a large number of suppliers. This improves planning quality and security. A win-win effect for the entire industry and for our customers. In the next few years, we expect a triumphant advance of the VDI 3805 data in international business. VDI 3805 is the right instrument for this as well.

Kermi currently makes data available to VDI 3805 for 4 product groups in 3 languages. A significant international expansion of the VDI 3805 catalogues is already ongoing.


Here are some of the improvements in VDI 3805 data in comparison to the BDH 2.0 data sets

  • presentation of the model ranges can be prioritised, i.e. popular models are given top priority
  • management of models is improved, i.e. new data sets no longer overwrite old designs
  • all output information is saved in accordance with EN 442 in the standard values according to 75/65/20
  • types of connections can be saved and minimum outputs can be assigned
  • geometric data, e.g. design data, connection data, noise space is available
  • assignment to additional VDI-3805 sheets is possible, e.g. radiators to fittings
  • Intelligent data structures allow a precise selection of accessories
  • VDI 3805 supports modern data formats, such as datanorm, STLB Bau, EAN
  • an image assignment can be saved
  • the VDI data set is a TGA solution which allows standardised data structures across the entire TGA
