This is not very efficient, especially if they are mounted in the corner of the room.
For this reason, there are convector radiators that include a fan in order to improve the heat distribution and circulate higher volumes of air through the radiator blades.
In this alternative approach, standard radiators are upgraded to convector radiators using commercial off-the-shelf components (COTS) for 35€.
Step 1: Assembling the fans
This type of fan is very silent and about the same width as the hot-water radiator. By joining 4 fans together, they cover almost the entire radiator length.
- 7 Plastic Blades
- Speed: 1600 RPM
- Airflow: 58 CFM
- Noise: 38 DBA
- Rating: DC 24V, 0.20A
These 4 fans were bought online for a total of 13.20€, plus 10.10€ for shipping.
The structural strength is given by the cable ties that pass through the holes in the corner of each fan, and join the fans together.
