Frequently Asked Questions

Who can install a hot water heater in Texas?

In Texas, a State of Texas Licensed Plumber is required for water heater installation unless you live on a homestead. A Homestead Exemption permit may allow non-licensed individuals to perform work on their owned and occupied premises, following specific procedures.

Professional assistance is crucial in navigating the complexities of choosing the right water heater, considering factors like fuel sources, models, and sizes. A certified plumber’s expertise ensures proper calculations, ideal temperature settings, and error-free installations, ultimately preventing costly repairs and premature failure.

Since 2007, Texas law mandates a plumbing permit for water heater replacement, requiring a licensed plumber to comply with state and local plumbing codes. Additionally, a licensed plumber must inspect the installation to confirm safety and correct operation, as errors can pose serious hazards.

The cost to install a hot water heater varies based on factors such as the type of heater, capacity, location, and any additional plumbing work required. On average, as of my last knowledge update in 2022, the installation cost for a standard 40-50 gallon gas or electric water heater might range from $300 to $900, excluding the unit’s cost. Tankless water heaters, being more complex, could incur higher installation costs, ranging from $1,000 to $3,000 or more. However, these are general estimates, and actual costs can vary significantly. To get an accurate estimate for your specific situation, it’s recommended to obtain quotes from local plumbing professionals.

The installation time for a new hot water heater can vary depending on factors such as the type of heater, the complexity of the installation, and any additional plumbing work required. In general, a straightforward replacement of a standard tank-style water heater might take around 2 to 4 hours. However, if the installation involves switching from a tank to a tankless system or if there are complex plumbing modifications needed, the process could take longer, potentially spanning a full day. Call Radiant Plumbing and Air and we’ll get you a quick quote for installing a new hot water heater in your home.

Signs of a failing water heater include inadequate hot water supply, unusual noises like popping or banging, visible leaks around the tank, discolored or foul-smelling water, fluctuating water temperatures, and increased energy bills. Additionally, the presence of rust on the tank, corrosion on the burner or flue, or frequent pilot light outages can indicate potential issues. If you observe any of these signs, it’s crucial to address them promptly, either through DIY troubleshooting or by call Radiant Plumbing to assess and remedy the problem. Early intervention can prevent more extensive damage and ensure the continued efficient operation of your water heater.
