RADIATION AS NATURAL THERMAL ENERGY
A comfortable indoor climate could be characterised by a pleasant indoor temperature without draughts. Simply put, you are comfortable in the room, whether you are in an office, conference room, sports hall or hotel room, for example. And that's exactly the feeling radiant heating can give you. But what do we actually mean by radiant heating? Radiant heating is a very natural way of transferring heat energy. Such radiation is invisible to the human eye as it is in the infrared part of the light spectrum. Nevertheless, it is perceived by humans, in the form of heat.
The intensity of radiation depends on the surface temperature of the source. The higher the temperature of the source, the more intense the radiation and at the same time acquires a greater range. When a sufficiently high intensity is reached, the radiation even moves to the – for humans – visible part of the infrared spectrum and the energy source begins to glow. A typical example is a light bulb that both serves as a light source and radiates heat.
Radiant heating systems can use the invisible part of the infrared spectrum very effectively, even in rooms up to 30 metres high. They have a relatively high surface temperature, thanks to which they radiate heat through the air to solid objects in the room, but also to the surface of the human body. The surface of these objects is then heated naturally and, more importantly, more evenly, with significantly lower energy consumption.
MAIN BENEFITS OF HEATING AND COOLING CEILINGS
Design and functionality
- 50 years guaranteed functionality
- High heating and cooling performance

- Heating power from 50 to 140 W/m²
- Immediately perceived heat or cooling effect – fast reaction time from 2.5 minutes
- Evenly distributed heat throughout the space and throughout the height of the building
- Ideal to combine with renewable energy sources e.g. heat pump
- Can be combined with other air handling elements
- Compared to underfloor or wall heating, ceiling heating can emit heat undisturbed and is not blocked by thick carpets or large pieces of furniture.
Health and comfort
- No dust swirling - minimal spread of bacteria and viruses, advantage for allergy sufferers
- Absolutely silent operation and draught-free cooling
- The air does not dry out during cooling, as is the case with conventional air conditioning
- Up to 45% savings in operating costs
- Quick return on initial investment (2.5-3.5 years)
- No additional costs for electricity, repairs, maintenance, revisions
- Low operating costs. For heating, you only need to heat the water to 30 °C, which is significantly less than, for example, conventional radiators, where the water temperature is usually 55 °C. In summer, you don't need to cool the water too much for cooling, as a temperature of 18 °C is sufficient for comfortable cooling, compared to 7 °C for conventional air conditioners.
Ceiling radiant systems can be purchased in several material variants. The material variants, or also the heat transfer surfaces that serve as an energy exchanger for heating or cooling in your interior by radiating either heat or cold, have different performance characteristics and thermal conductivity due to their different characteristics. So, before you start choosing a heating and cooling system, consider which material will be the most beneficial to invest in. For comparison, we have selected the most common ones that customers ask us about. Is it a system made of plastic, copper and aluminium, or a carbon (carbon) system. Apart from the common advantages of all of them, such as the invisibility of the systems in the interior and the comfortable functionality without any noise, they have different material properties, which we will focus on below.
System with plastic heat exchanger
The system is a plastic pipe in combination with plasterboard. The cold/heat pipework is either built-in or installed above the plasterboard. The system is designed for dry construction with quick installation and is particularly suitable for renovations. However, the disadvantage of the system is the plastic piping with problematic durability. This is limited and temperature dependent for this material. Usually, the plastics used to make ceiling heat exchangers do not have an oxygen barrier, so the systems become aerated and the metal parts in the hydraulics of the system corrode. The whole system must therefore be separated by an exchanger, on which there are power losses, and the source must produce a higher temperature for heating and a lower temperature for cooling. As such, the system is suitable for less demanding buildings in terms of performance and indoor comfort requirements. The issue of recycling, which is not entirely possible in the case of plastic, is also not negligible.
System with metal heat exchanger
The system, which consists of an aluminium-copper structure hidden above a plasterboard ceiling, is suitable for any architectural design. It can also be used to create seamless full-ceiling or island ceilings. Because we design the system to suit the specific room, there is no problem with installing built-in ceiling components. We also combine the system with special plasterboard with increased thermal conductivity and noise absorption capabilities. Due to the fact that it is composed of plasterboard and metal construction, this system guarantees better performance and thermal conductivity than a system with a plastic heat exchanger. The system is very flexible and can be tailored to the customer's ideas and the requirements of each individual room. It is suitable for buildings where high performance and indoor air comfort are required. Moreover, even at the end of its service life, the material can be reliably recycled for further equivalent use.
System with carbon heat exchanger
This advanced full ceiling system takes the advantages of the metal system described above and pushes the boundaries of performance even further. The advantage is its lightweight design combined with high performance and excellent acoustic properties. In this case, the ceiling is composed of a carbon plate, with built-in copper piping for heat and cold distribution. The fundamental difference from a plastic heat exchanger system, however, is in the duct material. Copper piping has a long service life and excellent conductivity, which is further enhanced by the excellent properties of the carbon plate. The carbon heat exchanger system is one of the top solutions available on the market due to its properties, but this also results in a higher purchase price. Again, these are excellent recyclable materials.
COMPARISON OF PERFORMANCE AND THERMAL CONDUCTIVITY OF MATERIALS
If we want to quantify the properties of the individual materials in the system, we can briefly mention their performance and conductivity. In terms of cooling performance, copper is the material that will serve you best, followed by aluminium with a performance about 37% lower and plastic, which is up to 60% lower than copper.
However, when choosing a suitable ceiling system, we are interested in the thermal conductivity, which is essentially the rate at which heat spreads and transfers from one heated part of the material to another. It is indicated by the symbol λ (lamda) and the unit is W/m.K. For comparison, the thermal conductivity of copper (at 20 °C) is 395 W/m.K. In contrast, the thermal conductivity of aluminium is 229 W/m.K and that of plastic is only 0.18 W/m.K.
WHERE DO HEATING AND COOLING CEILINGS FIT?
- Sports, industrial, manufacturing and other large halls and buildings
- Office buildings, congress premises, shops, schools, hospitals
- Apartments, family houses and smaller buildings with a high claim to aesthetic design and inner comfort
- Ideal for renovation of apartments, apartment buildings, offices and technological areas
ARE YOU RECONSTRUCTING?
If you are planning a renovation in your house or building and would like to significantly reduce the cost of running the house, this is the right time to consider the purchase of heating and cooling ceilings. In addition to the fact that you will be able to start enjoying all the benefits described above, you may also be interested in the fact that most ceiling systems can be installed in plasterboard ceilings and therefore it is not necessary, for example, to dispose of the existing floor or otherwise drastically interfere with the interior of the house.
If you are renovating old or listed buildings, you will be able to preserve beautiful floors. In addition, with ceiling heating and cooling systems, you will have complete freedom in interior design.
