Q: What size breaker does a hot water heater need?

• <div><p>When wondering <a href="https://www.angi.com/articles/what-size-breaker-for-water-heater.htm">what size of breaker for a water heater</a> 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.</p></div>

Q: Does installing a water heater yourself void the warranty?

• <div><p>Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty. However, even if you get away with performing the task yourself, incorrect installation, lack of a building permit, and improper repair work, regardless of licensing status, can all render your water heater unprotected by both the manufacturer's warranty and any installation warranties. </p></div>

If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home.

Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.

Every type of water heater has its advantages and disadvantages. Understanding those can help you decide the best type for your situation and budget.

Pros

Safer than gas or propane
Doesn’t require extensive venting systems
Lower upfront costs
Simpler to operate
No pilot light
Easier installation
More efficient heating than gas models
Available as point-of-use (POU) and whole-house units

Cons

Slower to heat water
Longer recovery time
Possibly higher operating costs
Doesn’t work during a power outage
Costs can increase without a 240-volt connection
