WATER UNDERFLOOR HEATING WITH A CHARACTER OF STEEL
WATER UNDERFLOOR HEATING WITH A CHARACTER OF STEEL
Stahlmann's water underfloor heating system uses stainless steel corrugated tubes for high comfort and reliability, offering a lifetime warranty. It is designed for easy installation and efficient heat distribution, with control options via room thermostat or smartphone.
The system comprises corrugated tubes, Eurocone fittings, thermal insulation, circulation pump, ball valves, bypass, distribution cabinet, thermostat, mixing unit, manifold, and optional accessories.
These tubes provide flexibility, high heat transfer efficiency, and resistance to temperature and pressure changes, with a corrosion-resistant lifespan of at least 30 years.
Made from high-quality brass and stainless steel, these fittings allow quick installation without additional tools, ensuring a tight connection to the manifold.
The system offers uniform heating, reduces dust circulation, maintains natural air humidity, and saves 25-40% energy compared to radiator systems. It is compatible with other heating types and has a long service life.
Key steps include preparing the floor, installing distribution cabinets, laying insulation, waterproofing, installing tubes, connecting to the manifold, performing hydraulic tests, and pouring screed.
Typically installed in a sand-cement screed on reinforced concrete slabs, suitable for various buildings. It involves waterproofing, insulation, tube installation, and screed pouring, followed by floor covering.
Uses gypsum-fiber boards instead of screed to avoid excessive weight, involving insulation, tube installation, gypsum-fiber boards, and tile adhesive, followed by floor covering.
Manifolds distribute the heat carrier across circuits, requiring flow meters on the supply manifold and thermostatic valves on the return manifold for uniform temperature distribution.
Manifolds should be centrally located for optimal performance. Eurocone fittings allow easy tube connections without additional sealing materials.
Adjust the lower locking ring to set the desired flow rate, matching the required value indicated by the red float.
Feature thermostatically controlled shut-off inserts. Electro-thermal actuators are recommended for multi-zone systems to isolate circuits when not needed.
Retain blue caps from return manifolds for future maintenance. An overpressure bypass valve or pump switch-off device is recommended to prevent damage when all loops are closed.
The pump-mixing unit maintains the desired temperature, mixing hot water with cooler return water to prevent overheating.
Prevents pump malfunction by opening when system pressure exceeds a set threshold, allowing circulation through a closed circuit.
Includes components like drain valves and air vents. The mixing unit circulates the heat carrier, mixing hot water from the boiler with the return manifold.
Configurations with and without pump-mixing units, with optional components like ball valves and tees with thermometers.
Compensates for screed expansion, prevents cracking, and provides thermal and acoustic insulation.
Direct heat upwards, covering the entire floor area. Castellated panels made of dense polystyrene foam are recommended.
Tubes should be laid at intervals of 100-250 mm, avoiding lengths over 80 m to prevent hydraulic losses. Patterns include "Snail" and "Serpentine."
Necessary for rooms over 40 m² or with walls longer than 8 meters to prevent screed cracking.
System must be filled with a clean heat carrier and tested at 6 bar pressure for leaks before screed pouring.
Suitable materials include ceramic tiles, laminate, stone, carpeting, and certain wood coverings, with thermal resistance not exceeding 0.15m²•°C/W.
Involves filling, testing, and balancing the system, including deaerating circuits and ensuring proper flow rates.
Tables provide flow rates and pressure drops for different tube diameters, essential for system design and efficiency.
Flow and pressure drop data for pipe diameters DN32, DN40, DN50, with flow rates in m3/h and pressure drops in bar/m.

ADVANTAGES OF WATER UNDERFLOOR HEATING COMPARED TO RADIATOR SYSTEMS Radiator heating 24 °C Water underfloor heating Uniform heating of the entire room is caused by heat dissipation from the entire surface of the floor, rather than by convection — this heating is more comfortable No dust circulation due to the absence of warm air convection Air humidity is kept at natural levels Hygienic, since underfloor heating is easier to clean and disinfect than radiators The safety of water underfloor heating eliminates injuries from the heating device, e.g. bruises or burns from contact with the radiator...

WATER UNDERFLOOR HEATING DESIGN The most effective and reliable way to install water underfloor heating is to lay a corrugated tube in a sand-cement screed, which provides maximum comfort and heat dissipation. Laying of such system is only possible on a solid loadbearing reinforced concrete slabs. This is the kind of installation that allows you to get the maximum heat output from the surface of the underfloor heating. And only this kind of floor heating can act as the main heating source. In particular, concrete systems have high strength characteristics. The load on this type of floor can reach...

DISTRIBUTION MANIFOLD Manifolds are designed for efficient distribution of the heat carrier over the floor heating circuits. Corrugated tubes are connected to the manifold with eurocone fittings. The eurocone fittings make it possible to connect the tube without additional sealing materials, using only a wrench. The design of manifolds for underfloor heating is quite different from those for water supply and radiator systems. Underfloor heating manifolds must have flow meters on the supply manifold and thermostatic valves on the return manifold. Flow meters are necessary for balancing the heat...
