Water Heater Repair and Installation
Most water heaters last between 8 to 15 years. Newer models last even longer if proactively maintained. If your water heater has stopped working, is leaking, or needs to be replaced, Ben Franklin can help. We’re your local experts for conventional and tankless water heater installation and repair in the Dallas area.
Water heater problems like sediment buildup not only compromise your heater’s effectiveness, but also significantly reduce its lifespan. Make sure your water heater is installed properly and receives regular maintenance to avoid these problems. Understanding how a water heater works and basic maintenance can keep yours delivering hot water to every corner of your home for years to come.
How Does a Water Heater Work?
There are two types of water heaters: conventional and tankless. Here’s a quick synopsis of how each works.

- Conventional water heaters are more popular. These are the large cylinders you find in most basements. A large (40-60 gallon) tank holds the hot water until a faucet or appliance calls for it. To create the hot water, a dip tube deposits cold water from your water main in the bottom of the tank. A gas burner or electrical heating element clicks on and heats the water. As it’s heated, the hot water rises to the top of the tank, ready to use. As you use your hot water, more cold water is added at the bottom of the tank. A thermostat continually tells the burner when more heat is necessary to regenerate the supply.

- Tankless water heaters work on demand. They don’t have a tank for storing hot water. Instead, a gas burner or electric coil activates when hot water is called for. Cold water travels through the heater and is instantly heated as it travels through the unit on its way to the shower, faucet or appliance that needs hot water. Tankless water heaters are also called “on demand water heaters” because they only activate when needed.
Tankless models cost more upfront but will last 20+ years and require less energy to operate. Click to learn more about the pros and cons of conventional vs tankless water heaters. A certified plumber can also help you decide which hot water heater is best for your home.
How Much is a Water Heater?
If you’re having water heater trouble, chances are the first thought to cross your mind is “How much to replace to a water heater?”
A new conventional water heater will run you somewhere between $400-$1,600. A new on demand heater can cost between $1,000-$4,000 depending on the model and what size tankless water heater you need.
You’ll also need to consider how much it costs to install a water heater. Installing an instant hot water heater or changing the location of the water heater in your home, may require you to move gas or plumbing lines to accommodate the change. A plumber can explain how you install a tankless water heater and whether it makes sense in your home. Check out our current offers for ways to save on tank and tankless water heaters today.
Why is My Hot Water Heater Leaking?
A leaky hot water heater is never a good sign. It may be that a pipe connection is loose or it could be a more serious issue within the unit. To be certain that your water heater continues to work safely, have water heater leaks serviced by a professional.

Water heater FAQ
How can I stop sediment from building up in my water heater?
Make sure you’ve set your heater’s temperature to the recommended setting (which is usually 120℉) to help prevent calcium and magnesium deposit accumulation. Installing a water softener will also help filter out sediment minerals. Most importantly, flush your water heater tank twice a year.
