Water heater installation and repair
Most Schertz homeowners don't think about their water heater until it stops working—no hot water in the shower, a puddle forming under the tank, or lukewarm water that never gets hot enough. Hard water from the Edwards Aquifer is the main culprit. Mineral deposits settle at the bottom of the tank, insulate the heating element, and eventually cause the tank to fail earlier than it should.
We handle water heater repairs, replacements, and new installs for both tank and tankless systems. If your water heater is leaking, making popping or rumbling noises, or not producing enough hot water, we'll diagnose the issue and explain your options. Sometimes it's a simple fix like replacing the heating element or flushing out sediment. Other times, replacement makes more sense—especially if the tank is over 10 years old or showing signs of corrosion.
Hard Water and Water Heater Lifespan
The Edwards Aquifer supplies most of the water in Schertz, and it's naturally high in calcium and magnesium. Those minerals settle at the bottom of your water heater tank as sediment. Over time, that layer gets thick enough to insulate the heating element from the water, which forces the heater to work harder and use more energy. Eventually, the sediment hardens and the tank starts to corrode from the inside.
Flushing the tank once a year helps, but most homeowners don't do it until there's already a problem. If you're hearing popping or banging noises when the heater runs, that's sediment buildup. If your hot water doesn't last as long as it used to, the tank is likely half-full of sediment. At that point, flushing might help temporarily, but replacement is usually the better long-term solution.
Tank vs. Tankless Water Heaters
Tank water heaters are the standard. They store 40 to 50 gallons of hot water and reheat as you use it. They're less expensive upfront and easier to install. The downside is they run out of hot water if you're doing laundry, running the dishwasher, and taking a shower all at once. They also take up more space and have a shorter lifespan in areas with hard water.
Tankless water heaters heat water on demand, so you never run out. They're more energy-efficient, take up less space, and last longer. The upfront cost is higher, and installation is more involved—especially if you're switching from tank to tankless. But if you have a larger household or you're tired of running out of hot water, tankless is worth considering.
Water Heater Installation Process
We remove the old water heater, check the gas line or electrical connections, install the new unit, and test everything before we leave. If you're upgrading to a larger tank or switching to tankless, we'll make sure your gas line and venting are sized correctly. Most tank replacements take a few hours. Tankless installs take longer, especially if we're running new gas lines or upgrading electrical service.
Frequently Asked Questions
How long does a water heater last in Schertz?
Tank water heaters typically last 8 to 12 years here, but hard water can shorten that to 6 or 7 years if the tank isn't flushed regularly. Tankless systems last 15 to 20 years with proper maintenance.
Why is my water heater making noise?
Popping or rumbling sounds mean there's sediment buildup at the bottom of the tank. As the water heats, it has to push through the sediment layer, which causes the noise. Flushing the tank can help, but if the buildup is severe, replacement is usually needed.
Should I repair or replace my water heater?
If the heater is less than 7 years old and the repair is minor (like a heating element or thermostat), repair makes sense. If it's over 10 years old, leaking, or constantly needing repairs, replacement is the better option.
Do you install tankless water heaters?
Yes. We install both tank and tankless systems. We'll walk you through the pros and cons of each and help you choose what makes sense for your home and budget.
How much does water heater replacement cost in Schertz?
It depends on the type and size of the heater. A standard 40 or 50-gallon tank replacement is straightforward. Tankless systems cost more upfront but save on energy over time. We'll give you a quote before starting any work.

What safety measures should I take during water heater installation?
Essential safety measures include turning off the power or gas supply, ensuring proper ventilation, using the correct tools, and wearing appropriate safety gear.
How can I extend the life of my water heater?
To extend the life of your water heater, regularly flush the tank to remove sediment, check the anode rod, maintain proper temperature settings, and schedule annual inspections.
