I have three storage heaters that are causing a bit of a head scratch.
All three storage heaters are around 3.4kw, each with four elements rated at around 850w.
Storage Heater 1: Working well, seems to output a good amount of heat for a given setting.
Storage heater 2: For the same setting, stores and outputs less heat than heater 1
Storage heater 3: For the same setting, stores and outputs less heat than heater 1.
My first thought is that an element has gone in 2 and 3.
Rather than testing all the elements individually, I tested them in situ and got a resistance reading for the whole unit.
Using the above reference, Storage heater 1 and 2 gave readings around 17.5 ohms. Am I correct that based on that reading, all the elements in these two should be functional?
The third heater gave a reading around 35 ohms, which I would assume means that potentially two of four elements have failed.
Would those conclusions be correct?
Now, this is where I am confused. Storage heater 2 seemily has a good resistance
reading, and therefore working elements. But, it is still out outputting less heat than Storage heater 1 for the same input setting. Maybe a 20 degree difference.
Could this be a thermostat issue? My thought is that perhaps the thermostat is not calibrated the same as storage heater 1 for example, or it has more wear and tear. So it is clicking off too early for a given setting.
So, an input level of 5 on storage heater 1 is not the same as level 5 on storage heater two?
Finally. I assume that if 2 elements may have failed in one heater, this is in a very small room. The heater is oversized. Is there any reason why the storage heater could not be run with only 2 working elements?
I assume that it will just pull less electricity, so there is no cost loss to running with a partially working storage heater.
Appreciate any thoughts.
