System review
The concept of the aquatherm black system is for the comfort of an occupied area: thermally well-balanced zones are created.
The principle of the aquatherm black system technology is gentle radiant heat from large surfaces delivering comfort and warmth to the occupants of a room. Since the heating surfaces are relatively large the surface temperature can be kept low reducing air movement. Radiant heat is felt directly, this is one advantage over small hot radiators that create high convectional currents warming the air before the occupants.
Since the system has a low flow temperature (25 – 35 °C) it is ideally suited to being used with eco-friendly fully condensing boilers or alternative energy sources like a heat pump, solar, geothermal and heat recovery systems. Besides the thermal advantages there is the added benefit of reduced air movement. The result is reduced dust movement with constant humidity.
In conclusion wall heating, resp. ceiling heating, saves 25-30% of energy costs and contributes to a healthy environment. Of course the aquatherm black system for wall and ceiling can be combined with each other.
Comfort
Moderate temperatures (20 – 35 °C) with large heating surfaces generates steady radiation for the user. Direct heat radiation on the human body delivers a comfortable warm feeling. The room air temperature can be reduced compared to conventional heating technologies (radiators/convectors) and still provides thermal comfort for the occupant.
OLD HEATING TECHNOLOGY Convection heat
1. Energy loss 1:
A high air temperature of at least 22°C is required to heat a room with air. Air is a bad heat carrier; therefore the energy costs are high.
2. Energy loss 2:
Even premium quality windows are the weak point of a house-insulation and result in high energy losses. The air heats up the glass and the engery leaks when venting.
3. Health at risk:
The air movement (warm air rises) kills the sense of well-being, too, since asthmatic and allergic persons have a primary problem with raising dust. This dust mixes with our breathing air and can lead to enormous burdens of the organism. An increase of the room temperature requires a reduction of the air humidity. Mucous membranes will dry out. The natural filtration system (nose) will be affected.
4. Discomfort:
Feet remain cold, as warm air rises up and is mainly in the upper area of a room. By that a feeling of discomfort is developed. The heating is adjusted to a higher level. The above effects will be increased.
5. Formation of mould:
Cold air strokes the wall, water condenses and creates the culture medium for the formation of mould.
The radiant heating with the new aquatherm black system
Comparable to the sun, the radiant heating first of all heats the solid and liquid materials in a room. Walls, ceilings and floors are constantly heated and the room temperature only in the second step. However, a high air temperature is not required for radiant heatings. An air temperature of 20°C is completely sufficient and provides a comfortable sense of well-being.
2. Energy saving 2:
There is no loss through the window. Heat radiation is reflected by glass and given back to the room.
3. Energy saving 3:
The room temperature is low. Thus you will not have any high energy loss, even when airing. The low air temperature creates a natural and pleasant climate.
4. Comfort:
In case of radiant heat, there are no differences in temperature of the room air, like with convection heatings. The head remains cool and the feet warm.
5. Dry walls:
Since the walls are directly heated, there is no condensation and consequently no formation of mould.
