Answer
Electronic controlled boilers can be used in accordance with the manufacturer’s data. Hydraulic steered, electric boilers or those using gas are not allowed to use. They can be used only if the manufacturer has given permission to use plastic pipes.

Answer
Basically yes. It has to be ensured that following parameters are not exceeded:
Heating: Operating temperature of max. 95°C for max. 100 hours at a maximum continuous operating pressure of 10 bar at maximum operating temperature (Tmax) of 70°C
Potable water: short term maximum temperature of 95°C for maximum 100 hours at a maximum continuous operating temperature of 70°C and a maximum continuous pressure of 10 bar. (for other pressure/temperature collectives please contact us)
Mounting/Installation has to be in line with manufacturer’s data.

Answer
YES – Water supply lines containing cold water have to be insulated against possible warming and condensation water (for example with Uponor coatings made of HD-PE or by choosing the pre-insulated Uponor Unipipe MLC pipe, available with an insulation range between 4-26 mm).

Answer
YES – for transporting fully desalinated water, the following Uponor Multi Layer Composite components can be used without restrictions:
Uponor Unipipe MLC pipes, dimension 16-25
Uponor composite fittings, dimension 16-25
Uponor screw connections MLC, dimension 16 up to 25-G3/4 Eurocone
Please note that all Eurocone connections already on site must consist of “FD-water” resistant material. For a reliable assessment of whether it is possible to use further components belonging to our Uponor MLCP system in combination with “FD-water,” a water analysis is required.

Answer
YES – when antifreeze admixtures are used, the Uponor MLCP system can operate within a temperature range of -40°C to 70°C at a maximum permanent operating pressure. It must be ensured that the antifreeze admixture in use does not affect polyethylene, EPDM, PPSU or brass.

Answer
Uponor MLC pipes installed in stables are resistant to the normal atmospheric ammonia pollution which can occur in such facilities. However, installed press fittings are exposed to a high corrosion potential. For this reason, such fittings should not be used on surface installations. If an on-surface installation cannot be avoided, the fittings should be protected using the corresponding measures/methods (e.g. by using corrosion protection manufactured by companies such as DENSO or KEBU).

Answer
YES – the Uponor MLC pipe can be frozen locally for repairing lines, without clearing the entire installation.

Answer
We do not recommend the use of Uponor MLC pipes within solar installations, since the operating temperatures may damage the Uponor Unipipe MLC pipe. Should the Uponor MLCP system be used in a solar installation anyway, you must ensure that utilisation at the maximum temperature of 95°C does not exceed 100 hours.
Basically, a maximum operating pressure of 10 bar at a maximum permanent operating temperature (Tmax) of 70°C should be observed (for other pressure/temperature combinations, please contact us).
However, in some circumstances even these stress limits cannot be applied when using solar installations. If the inhabitant of a house equipped with a solar panel is on holiday, there is no usage of warm water. This may lead to a backlog of heat which may damage the Uponor MLC pipe.
Should the Uponor MLC system be used in solar installations, it must be guaranteed that the above-mentioned stress limits are not exceeded.

Answer
The following values must be observed in the quick mounting of heat supply lines:
- Vmax < 0.3 m/s for radiator connection lines;
- Vmax < 0.5 m/s for radiator distribution lines;
- Vmax < 1.0 m/s for heating riser and cellar lines..
Additional information can be found in our technical guidelines.

Answer
Yes, the Uponor MLCP system can be used without restrictions for potable water. Regulations according to DIN 1988 and the German directive on drinking water (TrinkwV) apply in correspondence with DIN 50930-6 (Influence on potable water quality). The German DVGW (German technical and Scientific Association on gas and water) and other approvals have been granted.

Answer
Calibration is not necessary, bevelling is necessary, because without bevelling it is to hard to push the fitting in to the pipe.
