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

The cost to install a tankless system depends on your home’s infrastructure, such as venting requirements and the size of your gas meter. Because these units provide on-demand heat, the installation process is more technical than a standard water heater replacement. We provide a full assessment of your home to determine the final investment required for a seamless upgrade. 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?

Most standard tank water heaters are designed to last between 10 to 15 years. Tankless water heaters often have a longer operational life, potentially up to 20 years with regular maintenance. Factors like water quality and usage patterns in your Sioux Falls home can influence this. A professional can assess your unit's condition.

What are signs I need a new water heater?

Signs you need a new water heater include a frequent lack of hot water, rusty or discolored water, or visible leaks around the unit. Unusual noises or a noticeable increase in your utility bills can also indicate a problem. A qualified technician can accurately assess these symptoms and advise on the best course of action.

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

Sediment buildup at the bottom of the tank is a very common issue that can reduce efficiency and cause noise. Other frequent problems involve a malfunctioning thermostat or a worn-out heating element. Regular flushing can help prevent sediment accumulation. The pros are skilled at diagnosing and fixing these common faults.

Is it worth it to repair a hot water heater?

Repairing your water heater can be a cost-effective solution for minor issues, especially if the unit is still relatively young. However, if your water heater is old and requires multiple or extensive repairs, replacing it might be more economical in the long run. A professional can help you weigh the options.
