Your water heater is easily one of the most critical appliances in your home, yet it is often completely overlooked until the hot water stops flowing. While most units have a general lifespan of 8 to 12 years, you don’t have to settle for the average. With proper maintenance and regular care, you can significantly extend its service life to 15 years or even longer, ensuring your home stays comfortable for years to come.

Standard Water Heater Lifespans

There are a number of factors that influence the lifespan of your tank style water heater. Tank material, fuel type and your local water hardness levels will impact how long you can enjoy the warming comfort of your equipment. But most traditional hot water tanks will last about 12 years.

Tankless on the other hand, with proper service, can last you 15 years or more! Tankless water heaters last longer because they don’t require a tank to store and heat the water. The lack of tank helps prevent large scale mineral and sediment buildup, which can quickly corrode and cause irreversible damage to tank materials.

The Crucial Role Of Maintenance

Regular, proactive maintenance is the best way to ensure your water heater, no matter its type, stands the test of time. When you call in Beluga for your water heater tune-up, you can expect the following tasks to be completed with the utmost attention to detail to ensure all components are working together properly and efficiently.

Annual Flushing

Flushing your tank removes sediment that can build up due to hard water. High levels of sediment can corrode your tank over time leading to cracks and leaks. Flushing the tank also helps improve efficiency, because that same sediment build up can impact the heating elements in your tank, forcing your water heater to run longer and harder to reach and maintain temperature. Anode Rod Check & Replacement (if necessary)

Anode rods attract rust-causing minerals from your water helping prevent corrosion and tank damage. They typically need to be replaced every 1 to 3 years, depending on how hard the water is in your area.

Valve Testing

Another key component of our water heater tune-ups in temperature and pressure valve testing. This is important to ensure the ongoing safety and overall function of your tanked water heater.

Insulation & Efficiency Checks

If your tank is nearing the end of its lifespan, you might notice that your water isn’t as hot as you would like it to be. One reason could be a lack of insulation in the tank, resulting in standby heat loss. As part of our overall efficiency check, our technicians will inspect insulation levels and ensure all components of your tank are working well together to help your tank run as stress-free as possible.

Tankless Maintenance

While tankless water heaters don’t have all the same components as their tanked counterparts, the general maintenance tasks are actually quite similar.

Tankless water heaters require annual flushing as well, but in this case, it’s the flushing of water inlets, filters and water lines.

Our tankless experts will also ensure your heating element is descaled, and that your overall equipment is free of damage that could impede performance.

Signs Your Water Heater Is Failing

The most common signs of water heater failure are rusty water, rumbling or banging noises, leaks, and cold water. If you’re regularly experiencing even one of these issues, it’s best to call in the experts at Beluga Heating, Air & Electrical for an inhouse repair or replacement consultation.
