Benefits of Radiant Ceiling Heating in Old and Existing Buildings
Get Close to the Ideal Indoor Climate - Radiant Ceiling Heating and Cooling
Radiant ceiling heating kits for retrofitting make it most convenient to retrofit radiant heat in existing buildings. This is in particular valid for old buildings with high ceilings.
The radiant heat avoids air and dust turbulence, improves the indoor climate and thus promotes general well-being. This is why increasingly more hospitals and other medical facilities are retrofitting radiant ceiling heating systems.
The thermodynamic relationship "warm air rises upwards – cold air sinks downwards" plays a subordinate role with radiant ceiling heating. Ninety per cent of the heat transferred to the room is realised by radiant heat. The proportion of radiant heat is therefore significantly higher than with wall or underfloor heating.
The uniform heating of all parts of a room, its energy efficiency and possible use as a cooling ceiling make ceiling heating an all-rounder among the radiant heating systems. The FLEXIRO kit enables the benefits of ceiling heating to be subsequently utilised in old buildings.
Advantage Thermal comfort
The FLEXIRO ceiling heating system optimally implements the principle of radiant heating. The heat is emitted evenly over a large ceiling area via the narrow loops in the flexible polyethylene plastic pipe and can radiate into the room without being impaired by objects. Radiant ceiling heating therefore also creates astonishing thermal comfort in old buildings with low supply temperatures. Thanks to the high proportion of radiant heat, which is also radiated from the walls and floors, the human body feels just as comfortable with a 20°C indoor temperature as it does at 22°C generated by conventional radiator heatings.
The following illustration shows the temperature curves for different types of heating compared with the climate zones in the human body. Radiant ceiling heating comes very close to the ideal for space heating. This results in a uniform temperature pattern, which ensures a pleasant feeling of warmth throughout the body.
The graphic also shows that the floor temperature with a ceiling heating system is slightly higher than the indoor temperature, because the floor is also heated by absorption and reflection.
Advantage Health benefits
The comparatively low surface temperatures and the uniform temperature stratification in the room create hardly any air turbulence. This means that fewer allergens circulate in the air. People who suffer from house dust allergies especially appreciate this advantage of ceiling heating. Just as with underfloor heating, mould formation is actively prevented, as cold bridges at corners or window reveals as well as temperature differences in the room are prevented from the outset by uniformly heating the large surfaces. Radiant ceiling heating creates a comfortable, homogeneous and healthy indoor climate even in old buildings.
Advantage Interior design benefits
Another advantage of ceiling heating is its invisibility. No unsightly radiators restrict the interior design and furnishing possibilities. Radiant ceiling heating systems control the temperature of the room inconspicuously by also radiating their heat evenly to the floor and walls and "heating” these as well. The result: An even, radiant heat all around the body. Anything is possible.
Advantage Economic benefits
With a radiant ceiling heating system, the lower supply temperatures also ensure fast response heating in old buildings while at the same time saving energy and costs. The system allows the use of all energy producers and is an ideal supplement for utilising renewable energies such as solar energy or geothermal energy.
Advantage Cooling ceiling
The FLEXIRO kit can be used for cooling in summer without any modifications. Pleasant temperatures are therefore also guaranteed during the summer, even in rooms with large windows or under the roof.
