Underfloor heating

CHAPTER II

1. FITTING AND PIPES LAYING             

1.1. Installation prerequisites

Construction stage

Windows and doors should be fitted, plastered walls, as work on the surface immediately after the heating screed can move on.

• Rating

It is recommended that all rooms to mark the height of 1m above the finished floor 1m share badge.

• Niches

Have provided niches for mounting cabinets for distribution and crossing gaps in walls and floor to discuss with the architect incalzire.Se pipes designer and engineer of execution but structural resistance.

• Power utilities

Checking and ensuring the existence of connections for electric current and water                    

(For tools and Pressure Test).

• Bearing floor.

Portent floor must be solid and dry enough to dig over and present a surface float as stipulated in DIN 18202.

• Insulation made by the manufacturer

Floor rooms that come in contact with the ground will be insulated against moisture.

• Mounting conditions

• Installation Plan

Existing plans is absolutely necessary for laying arrangement and execution of the heat register.

• Joint Plan

Joint plan is required when the heat register arrangement must consider joints.

1.2. REHAU System

• Nuturi plate version

The installation begins with the application of adhesive tape perimeter.

This has continued, along walls, door frames, floor voids and traps wardrobe dealer, so flooding is not possible to cast screed.                                                                                                                                  To prevent noise and thermal bridging at junctions band will overlap a portion of 5cm.

Band must have a minimum height of 2 cm higher than finished floor height.                                                      Perimeter band will not be cut until after completion of all works on the floor.                                                 In wet areas it is recommended sealing the joint between wall and floor finish with elastic material.

The foil tape is applied over the perimeter nuturi plate.                                                                                   It thus prevents moisture penetration between the insulation and tape perimeter. .                                                           Next apply the nuturi plates.

Report will follow mandatory distribution nuturilor (distance between nuturi and their arrangement) to be maintained, it has a great hook to position the step 7.5cm tubes. Impermeable layer is not necessarily required by the rule because it is already included in nuturi plate.

                                                                                                                                                          

• REHAU PE foil will protect against damage, to prevent occurrence of noise and thermal bridges and to prevent water infiltration preparation of digging into the insulation layer.

Warning! It does not replace the foil cover layer barrier against steam which may be necessary and no sealant layer from moisture from below.

Note! The construction floor area where there is a sense of expansion, and it must fit mesh section.

• Heating-mode registers Installation
• REHAU underfloor heating systems allow the laying of heating registers in different ways:

a)      in spiral or ring

       b)in spiral-meander

For both modes are available following reasons: the floor surface temperature is more uniform as the distance between tubes is smaller and the more tubes are immersed in digging deeper.

Water increases with increasing temperature and temperature difference between tube heating surface that is tubes.                                                                                                                                                          The heat of a room can be covered regardless of their installation so that option depends on how demanding correct installation.

Heating system has the major task requirements cover both thermal and creating an atmosphere pleasant, so the choice of laying will take into account that the heat of a room is not uniformly the whole surface area but higher in exterior walls , reducing the interior room.

Needs high heat to the outside wall or in front of windows can be solved by modulating the distance between the tubes, namely in the area with high heat necessary tubes will be placed closer than the rest of the surface

Laying in spiral tubes leads to an average surface temperature uniform and allows a good adaptation of the caloric density of local siting.                                                                                                                          It is preferred findca lead to curves 90 and not create problems in tubes of plastic to the loops 180 and appearing at the location in the form of meanders, where they enforce the radius of curvature maximum allowed, so as not to damage the tube .

It added that the laying of the spiral is more evenly distributed surface temperature, because groups of adjacent tubes, cooler in this area has a lower average temperature. Heat current will flow from areas where digging is strongest where it is heated toward the less heated.

As a result of these factors in the floor surface temperature can be maintained at significantly lower values ​​in the area and is scalable so that it is clear that physiological limits will be exceeded.
