How does dust affect the efficiency of a heater? Verified

Dust can accumulate on the heating elements and in the air filters of a heater, reducing its efficiency. This can cause the heater to work harder to produce the same amount of heat, leading to increased energy consumption and higher utility bills. To maintain the efficiency of your heater, make sure to clean it regularly and replace the air filter as needed.

How do I determine the size of heater I need for a room? Verified

The size of the heater you need for a room depends on the size of the room and the insulation of the space. A general rule of thumb is to use 60 watts per square meter of space. For example, if a room is 14 square meter, a 840-watt heater would be appropriate.

Manual Stiebel Eltron CNS 200 S Heater

I have 2 CNS 200S wall converters, but I still have the previous model with the manual controller 1, 2, 3,.... I set it to 1 or 2, but it heats up all the time at full power, gets really hot. How can you lower the temperature? I just want to temper the room slightly.

I am a Consulting Engineer and I had to help out a friend who had a Stiebel Eltron electric heater Type CNS 200U 2000W 240V Number 220 731 9056 IP24. 601856. She tells me that this radiator is not more than 5 to 6 years old. After checking all the elements, I see that the heating body is defective. I am very surprised because the device was installed in good conditions. I find that abnormal. Can we replace it without sending it? And what price? Thanks for the answer
