What to Do When Your Water Heater is Rusting on the Bottom

Your water heater does best with steady maintenance from an experienced plumber. This annual service gives you the opportunity to react quickly and resolve likely problems. One such issue is a rusty bottom on tank water heaters

Rust can take root in several places on your water heater and can be the result of damaged connections. But rust on the bottom of your water heater’s tank may be pointing to a more serious problem. We would advise hiring a professional like Service Experts Heating, Air Conditioning & Plumbing to find out if the tank’s interior liner has rusted. This occurs after the anode rod fails. When operating as usual, the anode rod filters impurities from the water. 

When your tank has rusted, it’s a good idea to schedule water heater replacement. Otherwise, you risk having your home flooded with gallons of water when the tank gives out. 

Here are several other signs that your water heater is on its way out. 

4 Clues You Need Water Heater Replacement 

While your water heater can’t inform you exactly when it’s going to shut down, these are frequent signs that it’s about to happen. 

1. Age 

A dependable water heater usually lasts for close to 10 years. If yours is around this age or older, it’s a smart idea to consider replacing it even if it’s still running. That way, you can avoid a lack of hot water or a mess if the tank leaks. 

2. Rusty Water 

This is evidence that your water heater’s tank is rusted down. Your water might taste odd or stain your clothes when you wash them. While rust isn’t necessarily harmful, it affects your water quality and can also stain your bathroom fixtures. 

3. Reduced Hot Water 

Your water heater should deliver ample hot water, even if you’re showering and washing clothes at the same time. If you learn yours is struggling even with low use, it’s time to get an upgrade. 

4. Abnormal Sounds 

When your water heater’s anode rod malfunctions, sediment collects in the tank. As a result, your water heater must work harder to heat water. This can result in clanking or knocking sounds, as well as larger energy bills. 

Tankless Water Heaters vs. Tank? What’s Right for My House? 

Our trusted plumbers will recommend what’s best for your specific needs and your home. When thinking about hot water heater replacement, they’ll help you pick between tankless water heaters and tank models. Here are some of the key differences. 

Tank Water Heaters 

Tank water heaters are the most common type. They have a dedicated supply of hot water, which is ideal for heavy or frequent use. While these water heaters are the most affordable, they have some downsides. They are sizeable and constantly heating water, which is less energy efficient. And with a life span of about 12 years, they must be replaced more quickly than a tankless model. 

Tankless Water Heaters 

Tankless water heaters are valued for their energy efficiency since they heat water when told. Because they don’t have a tank, they can be squeezed in smaller spaces, like under your sink or in a closet. As another bonus, they usually last twice as long as a tank model. However, it’s wise to note they’re largely more expensive than tank models. But this cost can be offset by rebates since several models are ENERGY STAR® rated.
