The water heater is probably the most underappreciated appliance in your home. Really – without a water heater, you don’t have any of the following:
- Hot showers
- Hot baths
- Clean dishes
- Clean towels and sheets
- Hot water, period.
Given the significance of the water heater, do you truly know a good amount about it? We’re here to give you a couple things to think about when it comes to maintaining, servicing, and replacing your water heater.
The typical lifespan of residential water heaters is 10-12 years.
Natural gas and electric water heaters will typically last about a decade before you need to consider replacing the system. If you aren’t sure how old your water heater is, the date the system was manufactured will be displayed in the serial number which you can find on the ID sticker on the water heater tank.
Aging water heaters are nothing to ignore. A water heater that is ten years or older is at higher risk of getting a leak and resulting in water damage to your home. If your water heater is positioned in your attic or above the bottom floor, the chance of catastrophic damage rises. Be sure you have your water heater maintenance every year to avoid any leaks from causing damage to your home.
The most common malfunction of residential water heaters that will need replacement is a leaking tank.
It is highly recommended to have your plumbing expert install the water heater in a drain pan with piping that enables the pan to drain to the outside of your home and decrease the potential of water damage. Every water heater should have a operational and reachable cut-off valve on the inlet water supply to the tank, and a ball-type valve on the gas supply. For electric water heaters, an electrical switch off should be located close by.
If a water heater is “undersized,” in particular a gas water heater, the equipment will fail in a shorter time span.
When a gas water heater is routinely emptied of hot water due to significant hot water utilization, the gas burner fires repeatedly which can result in heavy condensation on the tank exterior. The condensation can create more expeditious breakdown of the steel tank. Additionally, the extreme heat from the gas burner on the underside of the water heater tank can also cause damage to the glass lining on the interior of the tank, which lowers the life expectancy of the water heater.
Water Heater sizing is a crucial replacement factor.
All water heaters are under pressure from the water supply, and as water is heated, it expands creating even more pressure. When thinking about replacing a water heater, it’s typically better to go with a larger 50 gallon tank, rather than a 30 or 40 gallon tank, providing the location will accommodate the larger size. The 50 gallon tank will also supply you more hot water capacity.
