When the heating in the apartment is not turned on, and city utilities do not even plan to do this in the coming winter, various types of homemade heaters are used. Why not use a central heating battery for this? After all, it is installed in the apartment anyway, let it be useful. This is what the author of the video thought, which we will now analyze.
How to make an economical heater
To implement his ideas, the craftsman removed an indoor bimetallic heating radiator. On the back of the battery the man placed carbon heating cable “KGK 12K/33 Ohm/meter.” This single core carbon fiber cable intended for use in warm floors. The battery of 5 sections took 7.7 meters. It is secured with tape. For thermal insulation, it is additionally wrapped in metal foil, on top of which one layer of insulation 10 mm thick is laid.
It was decided to abandon the use of classic heating elements for heating due to high energy consumption.
When turned on for the first time, the power of the heater was measured with a wattmeter. During operation, it did not exceed 200 W. The cable gets hot very quickly, within a few seconds the hand feels warm.
The upgraded battery was installed in place. For further tests will be used controllers for heated floors. Electronic thermometers with remote sensors are used to measure temperature. One is located in the air above the battery, the second is fixed below.
The heater is connected, we observe the heating efficiency. The initial temperature was +27 degrees Celsius. After just five minutes of heater operation, the temperature of the lower sensor reached +44 degrees Celsius. The air above the battery warmed up to +35.9 degrees Celsius. After 30 minutes, the lower thermometer shows +60 degrees Celsius. Sensor above the battery +40 degrees Celsius. Not bad!
The result is a functional heating device that replaces the missing central heating.
