1. General Over the past few years, underfloor heating has become highly popular for heating homes and industrial buildings. What was once considered to be relatively expensive can now be fitted or retrofitted in almost any building at low cost. The advantages are not only the cosy warmth provided and architectural freedom in interior design, but also the low flow temperature and energy saving aspects. Lower energy consumption means lower heating costs and a lower CO2 impact on the environment. This enables optimal use of renewable energies and condensing heating technology. Heat pump systems...

1.2 Laying methodsBifilar patternFeatures • mainly used for tight laying distances or awkwardly shaped rooms • uncomplicated pipe layout due to mostly 90° installation • uniform heat distribution • Bending radii must be taken into account • fast and easy installation in particular when using the rail system • heating circuit starting at window or external wall • slight temperature drops between flow and return • for laying in large window areas with preceding marginal zone for all types of buildings, in particular industrial underfloor heating, wall heating, concrete core activation, surface...

Standard Description EN 1264 states the minimum thermal resistance value (called U-value) in buildings. Heat insulation requirements for Germany are defined in the Energy Saving Ordinance (EnEV) and can exceed the values specified in EN 1264 in some cases. The specific heat loss of a building can be calculated by an architect or energy adviser taking into account the total thermal envelope. The assessment of the energy efficiency is documented in an energy performance certificate. The U-values of the respective components are documented in the energy pass and are compulsory for contractors. On...

Thermal insulation Rooms not for similar use*, unheated rooms (e.g. basements) and ground Outside air (-15°C) (e.g. underground car parks, thoroughfares) Example: Reference object according to German Energy Saving Ordinance (EnEV): Ceiling against outside air: U=0.28 W (m²K) Insulation roll 30-2 WLG 040 + 110 mm EPS WLG 040 Floor slab against ground and ceiling to unheated rooms U=0.35 W (m²K) Insulation roll / pipe positioning plate 30-2 WLG 040 + 80 mm EPS 040 For groundwater level < 5 m Thicker insulation recommended IMPORTANT!

Insulation layer thickness Floor RdA in dependence to insulation MAINCOR - Technical Manual MAINFLOOR

Installation of the MAINFLOOR dry construction system is subject to the following conditions: Substructures must be dry, firm, rigid and free from cracks, dirt and parting compounds must be removed. The dry construction elements must have full contact and rest flat against the substructure as the load distribution layers in dry construction systems are unable to compensate for any unevenness. Any unevenness must be compensated by appropriate measures. This can take place with dry fill material or earth-moist insulation; depending on the particular requirements, other compensating methods that...

Different types of MAINCOR PE-RT pipes are available. All MAINCOR underfloor heating pipes are oxygen tight according to DIN 4726. PE-RT pipe has five layers with an embedded EVOH layer. | | Outer layer of PE-RT □ Inner pipe of PE-RT Areas of application Underfloor heating Radiator connection Concrete core activation Open space heating Special applications MAINCOR - Technical Manual MAINFLOOR

MAINCOR PE-RT / AL / PE-RT multilayer composite pipe with embedded aluminium layer is oxygen tight according to DIN 4726. Despite being highly flexible, this multilayer composite pipe is characterised by high tenacity and fatigue strength.

2.4 Classification- according to ISO 10508 Pipe performance requirements are specified for five different application classes. The applicable classes are shown in the table below: Application class Each application class relates to a typical area of application and takes into account a service life of 50 years. Classification corresponds to the requirements in ISO 10508-4. All specified typical fields of application are recommendations and for guidance only. Each application class has a corresponding permissible operating pressure of 4 bar, 6 bar, 8 bar or 10 bar, depending on the particular...

2.5 Connection system The connection system is selected depending on the type of pipe used and machines available. Pressing system The pipe is cut off at right-angles, calibrated and deburred. The respective fitting is then pressed onto the pipe. Pressing takes place using a pressing jaw mounted on a suitable press. A tight connection is produced within 10 seconds. Sliding sleeve system The pipe is cut off at right angles, the sliding sleeve is fitted to the pipe. The pipe is then widened so that the fitting can be mounted. The sliding sleeve is moved with suitable sliding forks mounted on the...
