Why do water heater elements burn out?
The most common cause of burned out elements on new water heater installations or new element replacements is DRYFIRE. This happens because the installer fails to open a hot water faucet while the heater tank is filling with water and therefore purging or bleeding air from the system.
How do I know if my 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 long does a heating element last?
The heating element can last between 8 and 18 years if the dryer is well-maintained and the vent and lint traps are clean. The heating element can burn out if the dryer is not kept well-maintained.
Do heating elements go bad?
Heating elements typically last for several years, and hot water tanks outlast the elements. You need not replace heating elements periodically, only when symptoms arise.
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.
Will a bad water heater element use more electricity?
If the elements are dirty or there is an excess buildup of sediment in the tank, the hot water heater will use a lot more energy to maintain the same tank temperature.
How much does it cost to replace a water heater element?
Heater Element Replacement Cost The typical professional charge to repair your heating elements is $200 to $300. There are two of these in each unit, one at the top and one at the bottom. The top element controls the bottom element and, if it goes bad, your unit won’t be able to generate hot water.
Can you change a water heater element without draining the tank?
It is possible to change your water heater’s heating element without draining your tank. Although, keep in mind that it can be a bit more challenging.
Should I replace my 15 year old water heater?
Anyway, you should consider replacing your water heater if it’s about 6-12+ years old and when you start running out of hot water faster. However, age and lack of hot water aren’t everything. You could have a 15-year-old water heater that works just fine and wouldn’t need replacing.
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.
What makes heating elements fail?
A build-up of heat in the element occurs, exceeding the operating temperatures of the element, resulting in element failure. The nichrome filament wire inside the copper sheath burns in two and the heating element is damaged beyond repair.
How much does heating element cost?
A new heating element is usually between $40 and $100. This part might cost as low as $30 and as high as $200 or more, depending on the type of dryer.
