Robbens have launched Solar to compliment their energy efficient underfloor heating systems. Two types of collector are available in 2, 4 or 6 sq meter sizes, and these can be used with a choice of cylinder to make a complete kit.

Choosing your underfloor heating supplier is an important decision. Because the pipes are incorporated into the building structure, and often covered with concrete or screed, it has to be designed to give the right heating. Obviously you can't test the heating until the building is almost complete. A designed system which has calculated the complete heatloss for your building (where heat will leave through walls, windows, doors etc) takes away the risk. With Robbens, your designed system is guaranteed to perform to the temperatures specified in your quotation. Unfortunately, most other suppliers do not carry out a full heatloss calculation at the time of quotation. If a system didn't heat the property correctly, or there was a fault in the design, extensive works would be required to dig up pipe from the floors, and reinstall a correctly designed system. The Robbens insurance backed guarantee covers all associated costs should this occur. Having supplied thousands of systems since 1992, none of our customers have had cause to claim; because the system was designed correctly in the first place.
Too much pipe in the floor can be as bad as too little. Yes, the room will get hot, but what about the floor? In todays interiors, woodfloor features extensively. Wood is of course a natural product, and will change with heat. Most properly seasoned flooring will be suitable for use with a surface floor temperature of 27 degrees. Any more than that, and the wood will warp. Robbens quotations include not only the room design temperatures, but also the floor surface temperatures, allowing peace of mind in choosing a finish flooring.
Over the last year, a number of underfloor heating companies ceased trading due to the economic environment. This is a concern for customers when placing deposits. Robbens is part of Frankische, a large German pipe manufacturer, with a strong economic background. For added peace of mind, Robbens hold customers monies in a Client account, until the system has been delivered.
When choosing your supplier, check the following points
- Do they calculate your quote using a full heatloss calculation?
- Do they use multilayer pipe with an aluminium core?
- Do they provide both room and floor surface temperatures?
- Do they guarantee the design will provide the heat required?
- Do they tell you the exact boiler size needed to run the heating?
- Do they hold your deposits in a client account until the order is delivered?
- Do they offer technical advice and site visits by industry experts?

Production of a Multi-Layer Composite Pipe for Robbens Systems- Underfloor Heating
One of the most important parts of a warm water underfloor heating system is the pipe. Therefore, multi-layer composite pipes are found in more and more houses. Robbens Systems, one of the most experienced underfloor heating suppliers in the UK market, works with high quality multilayer-layer composite pipes by FRÄNKISCHE a leading European manufacturer of building and industrial pipes. As the name suggests, multi-layer composite pipes are made of several layers of different materials. But how do you produce multi-layer composite pipes? And how do you create a strong, permanent bond between aluminum and plastic?
Multi-layer composite pipes consist of five layers. The inside and outside layers are made of plastic tightly bonded, with special adhesive to the mid-layer of an aluminum core. Using the example of “alpex“ pipes manufactured by Fränkische Rohrwerke, we will explain the steps necessary to manufacture multi-layer composite pipes. FRÄNKISCHE produces high quality underfloor heating pipes for Robbens Systems who have been at the forefront of the UK underfloor heating market for over 15 years now.
The production of multi-layer composite pipes consists of five main stages. The real knowledge and know how is contained in numerous additional smaller steps. The raw material required for production is extensively scrutinized and tested before a single pipe is produced. Flawless raw materials are essential in starting multi-layer composite pipe production.
The extruder is the first stage in the production process. Plastic pellets are fed into the extruder. The melted plastic is then forced through a die to form the inner plastic pipe (inliner). Whilst still soft, the plastic extrusion is then passed through the vacuum calibration device and the cooling bath to cool and solidify. During the next stage, a second layer, the so-called adhesive layer, is applied to the inliner. This adhesive layer creates a strong, permanent bond between the aluminum pipe and the inner plastic pipe during the third stage. The aluminum strip is fed directly from the coil, applied and formed around the inliner and welded. At Fränkische Rohrwerke, they use the butt-welding technique. Butt welding means that the edges of the strip of aluminum are butted not overlapped, thus creating a butt joint. Because both pipes are cold at that point, the aluminum layer is heated to activate and cause the intermediate adhesive layer to permanently bond both layers together. Then another adhesive layer is applied to the intermediate product to bond the plastic outer layer to the aluminum in the fifth and final step. This will provide protection. After being pulled through another cooling bath and after all markings, such as quality certificate and DIN numbers, have been applied, the finished product is cut to length or coiled.
Advantages of the multi-layer composite pipe:
- Excellent sound absorption properties
- Optimum flow properties
- Corrosion resistant
- High chemical resistance
- Hygienic and toxic free
- Incrustation free
- 100% oxygen-tight
