Jeff Nunes, owner of Just Water Heaters has a wealth of knowledge in the plumbing and heating industries. His vast experience is one of the most valuable resources of our business.

Here are some of the most frequently asked questions.

How long does a water heater last?
Most tank water heaters last 8–12 years, while tankless (on-demand) units can last 15–20 years with proper maintenance. Factors like water quality, water pressure, and how well the unit has been maintained all affect its actual lifespan.

How do I know if I need a repair or a full replacement?
It depends on the issue. Leaks from the tank itself usually mean it's time to replace the unit, since a corroded tank can't be repaired. Other issues, like a faulty heating element, thermostat, or pilot light, can often be repaired instead. If you're not sure, send us a picture of your water heater along with the model and serial number, and we'll help you figure out the best next step.

What size water heater do I need?
Water heater size depends on your household's hot water demand, not just the number of people in your home. Things like the number of bathrooms, whether you have a large soaking tub, and how many appliances run on hot water at once all factor in. We can recommend the right size based on your specific household's usage.

Can hard water damage my water heater?
Yes. Hard well water and excessive water pressure can cause a water heater to fail prematurely by contributing to sediment buildup and corrosion inside the tank. If you're on well water, it's worth having your system checked to see if additional protection is recommended.

Is a tankless water heater worth the extra cost?
It depends on your household. Tankless units can be more energy-efficient over time and last longer than tank units, but they aren't the right fit for every home or budget. The right answer depends on your hot water usage, existing gas/electrical setup, and water quality. Give us a call and we'll walk you through whether it makes sense for your home.

How often should I have my water heater serviced?
We recommend having your system checked periodically to catch sediment buildup, corrosion, or worn components before they become bigger problems. Regular maintenance can significantly extend the life of your water heater and help avoid an emergency replacement down the road.
