Noctua, the famous Austrian brand of ultra quiet PC fans, found an original way for Optimize domestic heating. By exploiting active ventilation, its devices can be mounted on radiators for better distribute the heat and reduce consumption. A curious idea, which could prove to be very useful in unreal isolated houses or with low temperature heating systems.
Why don’t radiators always warm up well? And how to improve them without increasing consumption
In recent years, the cost of energy has undergone significant rise, leading many families to seek solutions for heat the house more efficiently. The main problem? The non -uniform distribution of heat.
Traditional radiators work for natural convectiona mechanism that uses the movement of the hot air to spread the heat in the room. However, if the temperature of the water that crosses them is low (for example in systems a heat pump or in district heating), the process can be slow and not very effective.
The result? Cold points in some areas of the house, need for raise the heating temperature (with consequent higher bills) and environments that struggle to reach adequate thermal comfort.
Noctua offers a simple but ingenious solution: ventilate the radiator To accelerate the spread of heat.
How active ventilation of radiators with Noctua fans works
The idea behind this system is the forced convection: instead of relying only on the natural movement of the hot air, an air flow generated by the Fans for PCwhich pushes the heat into the room quickly and efficiently.
The operation is quite simple:
- The fans are mounted on the upper or lower part of the radiatordepending on the most suitable configuration
- The hot air is actively pushed into the roomavoiding accumulation of heat only near the radiator
- The temperature complies fasterreducing the time necessary to heat the environment
- The temperature of the heating system can be reducedwhile maintaining a good level of comfort
This technique is already employed in some commercial devices such as it Speedcomforta heat amplifier designed precisely to improve radiator performance.
How much do you save with this technique?
According to Noctua, the addition of active ventilation to radiators allows Reduce energy consumption for heating up to 10% per year. The reason is simple: with a more efficient heat diffusion, you can Set a lower temperature without sacrificing thermal comfort.
But how much does it cost to install such a system?
- Noctua fans: Between 13 and 33 euros one (at least 2-3 are needed per radiator)
- Controller and accessories: about 50-80 euros For power supply, supports and sensors
- Estimated total cost: Between 80 and 200 euros for radiatordepending on the configuration chosen
Compared to ready -made heat amplifierswhich cost between 40 and 100 eurosthis solution could be more customizable, but also more expensive and complex to install. However, for those who already have unused harmful fansit could be an economic and smart way for recycle electronic components and improve domestic heating. You can take a look here:
