Awadukt Thermo is a ground to air heat exchanger, using the natural temperature of the earth to pre-warm or pre-cool filtered air, which is produced by Rehau. Air is drawn through a network of underground pipes made from a specially formulated polypropylene, which incorporates antimicrobial particles made of silver, to prevent microbial growth that can cause musty smells. The polypropylene also acts as a good heat conductor allowing excellent heat transfer. Due to the low velocity of air required, a small electrical fan is all that is necessary to draw air through the system and into the building via displacement floor grilles. Awadukt Thermo is capable of raising the temperature air taken into the building by up to 9K in winter and reduce the temperature by up to 14K in summer.

Underfloor heating, pipe-in-pipe pipework services, and cable management systems from Rehau have been installed at three primary schools in Exeter. The company's Raufix method was used to install underfloor heating in a double meander pattern with the pipe-in-pipe consisting of a flexible conduit through which pe-xa pipes run.

Meeting requirements for sustainable energy solutions, Rehau has launched a ground to air heat exchanger into the UK called the Awadukt Thermo. The system consists of a network of polypropylene pipes that are laid around a building 2m below ground level and fed by a filtered air inlet column. Instead of the building's ventilation system bringing air directly in from outside, it is drawn by a ventilation fan through the below ground pipe network. The air is pre-cooled in the summer and pre-warmed in the winter. The system achieves a Coefficient Of Performance of around 50. The polypropylene pipe is designed to ensure an air tight barrier to the surrounding earth. The material has a patented formulation containing thermally conductive additives which optimise heat transfer and a silver based anti-microbial layer to prevent the growth of microbes on the inner surface of the pipe, ensuring air hygiene is maintained. This increases thermal conductivity by 45%.

Underfloor heating from Rehau is being installed in the 28 bedroom hotel development at Foxhills Golf Club and Resort in Surrey. The 16mm Rautherm pipe has been laid throughout the 1500m? area using the Railfix fixing method. The heat source is a gas fired condensing boiler, and the company's cross-linked polyethylene pe-xa pipe has been laid to ensure constant temperature.

Haden Yound has awarded Rehau a contract to supply underfloor heating systems for six new PFI funded schools in Exeter. The underflor heating systems have been installed in the walkways, atruims, dining areas and sports halls of six new primary and secondary schools. They were specified to provide a cost effective, safe heating system for the busiest areas of the schools and have low on going maintenance requirements. In the sports halls, the underfloor heating systems have been laid using Rehau's Railfix fixing method which accommodates sprung floors. In all the other areas, it has been laid directly onto the floor reinforcement within the concrete substructure of the buildings.

Chosen to be efficient, comfortable and unobtrusive, new build mosques in Manchester and Blackburn now feature underfloor heating from Rehau. At the Old Trafford mosque, the heating was chosen as it is concentrated on the areas occupied by worshippers and energy is not wasted heating empty roof space.

Laid throughout the 2,200m² floor area of Volvo Truck and Bus headquarters in Glasgow, Rehau?s underfloor heating is providing efficient heating for the depots workforce. Underfloor heating was chosen because it heats the first few metres of occupied air space without wasting energy heating the empty roof space.

Elderly residents in 10 new housing association flats on the Orkney islands are likely to benefit from cheaper bills thanks to the installation of REHAU underfloor heating. The system relies on the company?s 16mm Universal PEX pipe laid on heat diffusion plates throughout a total of 19 flats including nine for family occupancy in two separate blocks.

Underfloor heating from Rehau has been installed in a new 10,000 sq ft factory built by Smiths, a Southend-based manufacturer of Rehau pvc-u windows. The system uses Rautherm 20mm universal pipe laid in a series of 20 to 40m² floor circuits. These were tied to steel reinforcement in the floor and pressure tested before a concrete floor slab was laid. The heat source is a gas fired condensing boiler. Mark Smith, the company?s managing director, chose underfloor heating for the factory because it would create comfortable conditions in the large, airy building economically. Heat is concentrated in the first 2-3m of air space occupied by the workforce and energy is not wasted heating the empty roof space. Mark Smith explained that the underfloor heating was more expensive to install than conventional options but those costs are being recovered by lower heating bills.
