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

Rinnai tankless units require regular maintenance to prevent scale buildup and sensor malfunctions. Our repair process involves clearing mineral deposits, inspecting the venting, and ensuring the gas pressure is optimal for your home. You need this service if your hot water output drops or the unit shuts down unexpectedly. 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 Knoxville

How long do hot water heaters typically last?

Tank-style water heaters usually last 8-12 years, while tankless models, like many Rinnai units, can often go 20 years or more with proper maintenance. Signs like rust-colored water, leaks, or strange noises are indicators your unit might be nearing the end of its lifespan. Regular check-ups can help extend their performance.

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

The cost to install a new water heater in Knoxville varies based on the type and model, like a Rinnai tankless versus a traditional tank. Factors include the unit's size, complexity of the installation, and any necessary plumbing or electrical modifications. You'll get a clear picture when you call for a free quote.

What is the most efficient type of water heater?

Tankless water heaters, especially advanced models like Rinnai's, are generally the most efficient. They heat water on demand, meaning you're not constantly expending energy to keep a large tank of water hot. This can lead to significant energy savings over time in Knoxville homes.

What are signs I need a new water heater?

If you're noticing lukewarm water, strange noises like popping or rumbling, or visible leaks around the unit, it's time to consider a replacement. Inconsistent water temperature or a sudden drop in hot water supply are also red flags. A free assessment can confirm if repair or replacement is best.

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

For tank-style heaters, sediment buildup is very common, leading to reduced efficiency and strange noises. For tankless units like Rinnai, issues can include mineral buildup in the heat exchanger or problems with ignition and airflow. These often require professional diagnosis and repair.

Is it worth it to repair a water heater?

Whether repair is worthwhile depends on the issue and the age of your unit. Minor repairs on a relatively new water heater are often a good investment. However, if your unit is older or facing major component failures, replacement might be more cost-effective in the long run for your Knoxville home.
