Capillary Tube System as Underfloor Heating in the Screed

Underfloor Heating in the Screed

 

Installation. The capillary tube underfloor heating is ideal for quick and simple installation within the cement screed or floating screed. The capillary tube mats are rolled out, set and sealed onto an existing insulation. In the floating screed, they are floating in the screed middle layer according to the fitting. Within the cement screed, it is possible to position the capillary tube mats either directly onto the insulation or also in the middle layer between two screed layers. The installation height of the screed can be reduced compared to thick tube meanders by exactly the difference of the tube density between the capillary tube (4.5 mm) and the conventional meander (16 – 20 mm). 

 

Advantages over thick tube meander systems in the screed:

lower system temperature for the same capacity;

even temperature dissipation;

parquet floor heating;

hypoallergenic heating;

quicker due to the screed middle layer;

lower installation height of the screed;

quick installation 

  

Technical Data  

Capacity heating / cooling: set for heat requirement / cooling requirement with the corresponding most energy efficient flow temperatures          

Mat installation height: 4.5 mm  

Element installation height: 35 – 65 mm (depending on the screed quality and producer specifications concerning coverage)  

Material flooring: all underfloor heating materials but also underfloor heating sensitive wood

COP plus (performance number increase heat pump/heating): Heat pump producer should adjust to allow for the improved performance number (COP) of W30, W28 or W26 depending on the project.

COP plus (performance number increase heat pump/cooling): complimentary cooling by connecting to wells or probes is possible. For surface collector or air-water heat pump make enquiries at your heat pump producer as to W16.
