Water Heaters FAQs, answered by experts

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

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.

The lifespan of a water heater depends on its type, usage, and maintenance schedule. Traditional tank-style water heaters typically last between 8 and 12 years, though the range can be as wide as 6 to 15 years. Within this category, gas models often last 8-12 years, while electric models may last 10-15 years. In contrast, tankless water heaters have a significantly longer lifespan, often lasting up to 20 years or more. Factors like heavy usage, hard water, and sediment buildup can shorten a unit's life. To extend its lifespan, it is crucial to perform regular maintenance, such as flushing the tank annually and scheduling professional inspections. If your unit is over a decade old and shows signs of rust, leaks, strange noises, or inconsistent heating, it is likely time for a replacement.

No, you’ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don’t always need to drain it completely. If you’re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you’re replacing the lower element, you’ll need to drain the whole thing.
