Are there different types of water heater elements?

Types of Hot Water Heater Elements. There are both ‘high density’ and ‘low density’ hot water heater elements. Low density elements are considered better, they last longer and are less prone to build up. The low density elements have more surface area and therefore do not need to get as hot.

How do I know if my hot water heater 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 I know if I dry fired my hot water heater?

Dry-fired elements can be recognized in three ways:

  1. The zinc plating will have melted or completely burned off, leaving exposed copper.
  2. The tubing of the element will be completely annealed (soft) to a point that it can be easily bent in the straight sections of the tube.

Will a water heater work with one element?

Yes, a water heater can still run if the bottom element quits. In most water heaters, the top heating element controls the thermostat and will still work even if the bottom element fails. So provided the top heating element is working, it can still produce some hot water even if the bottom heating element fails.

Do both heating elements work at the same time in a hot water heater?

When there is a problem with the thermostats/ element feature, then a water heater may not provide enough hot water. In a dual elements system, heating occurs in one element at a time, never simultaneously. When the water tank has cold water in it, the upper thermostat will heat the upper element.

Does length of water heater element matter?

Can I replace a 4500 watt water heater with a 5500 watt?

Can I replace 4500 watt elements with 5500 watt? You can definitely replace 4500 watt with 5500 watt and get 4-7 gallons more hot water from a tank.

Will a bad water heater element use more electricity?

Will a bad water heater element use more electricity? No. Whatever might go wrong with an element, for certain all the energy it takes from the electricity supply ends up as heat in the water (minus losses through the thermal insulation). There is no mechanism whereby electrical energy could end up anywhere else.
