Water Heaters questions, answered by experts

Choosing between an electric water heater vs. a gas water heater comes down to personal preference. Overall, electric heaters are more energy efficient than their gas competitors. They’re also quieter to operate, take up less room, and don’t come with a risk of gas leaks. 

The downside is that electric water heaters cost more to operate than gas. They might also struggle to heat water fast enough for households that use large amounts of hot water. Lastly, a power outage could cause your electric water heater to stop working, whereas gas water heaters may still function.

Your water heater's age can affect your homeowners' insurance policy. Many policies will ask how old the heater is when you first apply for a policy—and they may make you replace a model that's over 10 years old. 

Even if your policy permits you to have an older heater, it may significantly reduce the amount of protection available. If an older water heater suddenly leaks and causes damage to parts of your home, your policy may not cover it.

Not all types of water heaters require a venting system. Electric tankless water heaters don’t use natural or propane gas, so no venting is required. Instead, they use electric burners to heat water quickly and efficiently. However, any system that does use gas or propane will require ventilation.

Signs your water heater is about to fail include: a unit older than ten years, rust water coming from your faucets, banging and rumbling noises when you call for hot water, and leaks coming from the tank. You might also notice a foul odor when you turn on your hot water, akin to rotten eggs or sulfur. Of course, your water heater might also need replacement if your water doesn’t stay hot or takes longer to heat up.

When wondering what size of breaker for a water heater is appropriate, the majority of hot water heaters need a 30-amp, two-pole breaker. Most residential water heaters use 240 volts and between 3,500 and 5,500 watts. If your appliance matches these measurements, a 30-amp breaker is likely perfect. Owners of point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts often find that a 30-amp breaker is adequate. Water heaters that use more watts than average may need a 40-amp breaker. Smaller units that use fewer watts could potentially use a 20-amp breaker.
