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

An expansion tank protects your plumbing system from pressure spikes caused by thermal expansion as water heats up. We install this tank on the cold water supply line, which helps prevent leaks and extends the life of your heater. You need this installation if your home has a closed-loop plumbing system or if you experience relief valve dripping. 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 Sioux Falls

How long do hot water heaters typically last?

In Sioux Falls, most tank-style water heaters have a lifespan of about 10 to 15 years. This can be shorter if you have hard water or if the unit doesn't receive regular maintenance. It's a good idea to get it checked as it ages.

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

What is the most efficient type of water heater?

For energy efficiency in Sioux Falls, tankless water heaters are a great choice, heating water only when you need it. High-efficiency tank models are also very effective. A professional can help you determine which system best suits your hot water demands and budget.

What are signs I need a new water heater?

You should consider a new water heater if you notice leaks from the tank, if your hot water is discolored or smells bad, or if you frequently run out of hot water. Unusual noises like banging or popping are also indicators. Get it inspected in Sioux Falls if it's old.

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

Sediment buildup is a frequent issue, leading to noise and reduced heating efficiency. Other common problems include malfunctioning thermostats or heating elements. Regular flushing of the tank can help prevent sediment buildup and extend the life of your unit.

Is it worth it to repair a water heater?

Repairing a water heater is often worthwhile for newer units with relatively minor issues, like a faulty thermostat or heating element. However, if the tank is old or showing signs of corrosion, replacement might be more cost-effective. A technician can offer a professional recommendation.
