A water heater is an essential component of your home, making it necessary to keep up with its maintenance and replacement in order to keep the hot water flowing through the house. Knowing when to service or replace your water heater can help you save money and energy. It is often hard to tell when an issue with your water heater is manageable or when you should replace the entire unit.

At Armstrong Plumbing in Scottsdale, AZ, we want to help you learn what signs to look for when it is time to shop for a new water heater so that you can avoid any frustration and confusion. Here are a few of the most common signs it’s time to get a new water heater.


7 Signs You Need a New Water Heater


Not Producing Hot Water

Water that won’t get hot is one of the most obvious signs, of course. However, if you notice that your water is taking longer to heat up or is not heating at all, you should contact a professional. It is possible that a circuit has shorted or that the pilot light is out.

If you’re experiencing a frequent reduction in hot water, it may mean it is time for a new unit.


Unusual Noises

Noises coming from your water heater are a signal of a problem. Popping noises can be a result of mineral build-up or malfunction from the components inside the tank of your water heater. As sediment hardens in the tank, it can also cause banging or rumbling noises.

If you are unsure whether a specific noise is a sign of a problem, you should contact an experienced technician to inspect the unit.


Old Age

Water heaters typically have a lifespan of 8 to 12 years, and some water heaters can even last up to 20 years. This can depend largely on family size and water usage. If you know that it has been this long since you last replaced your water heater, or you cannot remember when it was last replaced, it could be a sign that you need to start shopping.

Replacing your unit in a timely manner allows you to maximize energy and water usage and avoid larger problems down the road.


An Unresponsive Thermostat

Needing to adjust the thermostat frequently is a sign that your water heater is giving out. You should have comfortable hot water when the thermostat is set between 120 and 140 degrees. At lower temperatures, the water will only feel warm.

If the thermostat is correctly set, inconsistency in the water temperature can be a sign of the heating components giving out.


rusty water


Rusty Water

Any discoloration in the water coming out of the tap is a sign of a problem. Water with visible rust is a very strong sign that it is time to replace your water heater. Over time, the pipes inside a water heater will corrode because of water and minerals flowing through them. When the water picks up this corrosion, it can be unsafe for you and your family. At this point, you should begin looking into a replacement unit.



If you see water settled around your unit or see water leaking out from a pipe or underneath the tank, then you should certainly look into a new water heater. A small leak or drip can be a sign of a much larger flood waiting to happen. Therefore, it is best to look into finding a new water heater as soon as possible.


Constant Repairs

Frequent repairs add up in time, frustration, and money. Although it may seem more cost-effective to repair your current water heater than buy a new one, consistent repairs are a signal that more repairs are on the way.

An inefficient unit can also be wasting money through heavier water and energy usage. Instead of pouring money into a unit that does not work properly, it is best to replace the unit entirely.

If you notice any of these issues, it is time to start shopping. Finding the right water heater for your home can be a daunting task, as there are many different systems and many different options. At Armstrong Plumbing in Scottsdale, we are happy to help you find the system that will be the best for you. We provide installation, repairs and can perform a complete safety inspection for you.

When shopping for a new water heater, you should consider the option of a tankless water heater. Offered using electricity or gas, a tankless water heater can provide an abundance of convenience you never thought possible. Electric tankless water heaters use infrared technology, requiring fewer components and less maintenance, but a higher upfront cost for replacement.

This innovation is also more efficient at heating water, allowing you to save energy and maintain a steady supply of hot water through your home. Meanwhile, the water heater is compact and can be mounted on the wall, providing you with more space in your home.

The majority of water heaters Armstrong Plumbing installs are gas-burning tankless water heaters. A big perk of gas water heaters is that they should operate 20 years or more, which is two-to-three times longer than tank-type heaters. Plus, most tankless gas heaters are about the size of a suitcase and hang on the wall.
