How do I know if my heating element is bad?

Touch a probe on the multitester to each screw on the element. If you get no reading, or a maximum reading, the element is bad. Elements do have some resistance, so a reading of 10-16 ohms is normal, with higher ohm readings for 3,500 watt elements and lower readings for 5,500 watt elements.

How do you calculate the power of a heating element?

2 Answers

  1. I=ER. substituting:
  2. P=E(ER) which simplifies to:
  3. P=E2R. If you have a 1000W heater which runs at 220V, I can calculate the resistance your heater must have:
  4. 1000W=(220V)2R.
  5. R=(220V)21000W. R=48.4Ω

Which element heats first on a water heater?

The upper thermostat takes first priority, heating the water to a preset temperature before powering up the lower thermostat to heat the water to its final temperature. Only one heating element will be active at any one time.

Does water heater element length matter?

Does the length of a water heater heating element make a difference? No, not as long as you have the proper voltage, watts and style. Shorter elements have a larger diameter therefore the same surface area.

Can you wire a hot water heater element backwards?

Can you wire a hot water heater backwards? Yes, you can get it with minimal effects. If the 220v heater has red and black wiring, it can be wired backwards. As much as this is possible, you must ensure you correctly wire the hot water heater to avoid water polarity issues.
