HOW DOES OPAL SYSTEMS FLOOR HEATING WORK?
One of the features of the OPAL SYSTEMS solution lies in the direct contact between the tubes, the diffusers and the floor covering.
A groove milled in the prefabricated panels attached to the floor receives metal channels and tubes that are simply “snapped in” by foot pressure.
The optimum diffusion of heat is ensured by specific diffusers and an expanded metal grid which, in combination with the tile or parquet adhesive, assembles the whole structure. The top screed is therefore no longer necessary.
This new heat emitter design makes it possible to reduce energy consumption for heating residential and tertiary sector buildings, in both new build and renovations.
It provides greater thermal comfort than the best systems currently available on the market, and allows installations to achieve high overall performance through its greater reactivity and operation at low temperatures.
OPAL SYSTEMS floor heating can be coupled with any type of boiler (oil, gas, condensation, pellets) and heat pumps. In the event of mixed-usage with radiators, only a mixer valve needs to be provided.
OPAL SYSTEMS INCLUDES THE FOLLOWING FEATURES:
- Its constituent materials are currently used in construction, and are environmentally neutral.
- Its double spiral installation is fast and simple and does not require screed cover.
- Compared to conventional floor heating, its emission power varies much more quickly, it takes up less space (< 2 cm) and it is lighter (12 kg/m²).
- Compared to lightweight floor heating solutions currently on the market, its maximum power is higher and better distributed.
REACTIVITY AND ALTERNATING OPERATION
The high reactivity of OPAL SYSTEMS floor heating enables its intermittent operation. Obviously, intermittent heating during times when the building is unoccupied always results in energy savings. The savings vary depending on the type of building (inertia, insulation) and the time it is unoccupied.
Moreover, if free sources of energy (sunlight, people, etc.) or energy from an electric or wood stove are detected by the regulation system, the low thermal inertia of the floor will not delay the effect of the cut-off or the restart.
“With traditional (heavy) floor heating, regulation based on the interior temperature should be avoided because it nearly always leads to discomfort. For example, when it starts up again in the morning, there is a significant discrepancy between the ambient temperature and the set point. The sensor demands maximum production of energy. When the ambient temperature is reached, the mass of the floor has accumulated too much energy, which causes the temperature in the room to be excessively high. It is possible that when this effect is actually felt (2 to 3 hours later), the gains may have disappeared. Emission will then be low, which in turn may be compensated for only very slowly.” See Architecture et Climat [Architecture and Climate]
Thanks to this feature of intermittent operation, OPAL SYSTEMS makes it possible to achieve energy savings of 15 to 35% (compared to continuous operation), while improving thermal comfort.
