What affects the price

When you are looking at the price of a new water heater, a few main things shift the final number. The type of unit you choose—whether it is a tank model or a tankless system—is the biggest factor. You also have to consider the fuel source, like gas or electric, and the physical space where the heater sits. If your home needs new venting, updated piping, or a different hookup to meet current safety codes, that adds labor time to the project.

About this service

Electric water heaters use heating elements inside the tank to warm your water. If your unit stops heating, we typically check the thermostat, the heating elements, and the electrical breakers. You need service if you are getting cold water or if the breaker keeps tripping. Exact pricing confirmed free on the call.

Even though it is warm outside, your water heater is still working daily. Summer is a great time to adjust your settings, as the incoming water isn't as cold, which can actually help extend the life of your unit. If you are planning a home renovation or just want to upgrade to a more efficient model, call us to talk through your options.

Frequently asked in St. Louis

How long do hot water heaters typically last?

Most electric water heaters typically last between 8 to 12 years. The lifespan can be influenced by factors like water hardness and the frequency of use. If your unit is approaching this age and you're noticing problems, it's a good indicator that a replacement might be necessary for your St. Louis home.

What is the average cost of putting in a water heater?

What is the most efficient type of water heater?

Heat pump water heaters, a type of electric model, are generally the most efficient. They work by transferring heat from the air to the water, using less electricity than standard resistance heaters. While the initial cost is higher, they can lead to significant savings on energy bills in St. Louis over time.

What are signs I need a new water heater?

Look for signs such as inconsistent hot water temperatures, unusual noises like banging or popping, or visible leaks from the tank. If your water appears rusty or has a metallic taste, these are also critical indicators. Don't wait for a complete breakdown in St. Louis.

What is the most common problem with a hot water heater?

Sediment accumulation at the bottom of the tank is a very common issue that can lead to reduced heating efficiency and noise. Another frequent problem involves the heating elements or the thermostat failing, which directly affects the water's temperature. These often require expert attention.

Is it worth it to repair a water heater?

Repairing a water heater is often a cost-effective solution for minor issues, especially if the unit is still under warranty or relatively new. However, if the tank is corroded, leaking, or the repair costs are substantial, replacing it might be a better long-term investment for your St. Louis residence.
