What our tankless installation includes
Every tankless install covers the essentials: unit mounting, water line connections, gas or electrical hookup, venting, and testing. We also pull the permit and haul away your old tank.

Work order
Tankless Water Heater Installation- Unit sizing and mounting: We calculate the flow rate your household needs, then mount the unit on a wall stud with the correct clearances. That means measuring, marking, and securing it so it stays level and serviceable for years.
- Water line connections: We connect hot and cold lines using copper pipe or PEX tubing, install a shutoff valve, and seal every threaded fitting with Teflon tape and pipe sealant. No drips, no callbacks.
- Gas or electrical hookup: For gas units, we run a dedicated line and pressure-test it with a gauge. For electric units, we wire a 240-volt circuit to the manufacturer's spec. Both get tested before we fire the unit.
- Venting installation: We install stainless steel venting through the roof or sidewall, following the manufacturer's length and slope requirements. Correct venting keeps exhaust gases out of your home and passes inspection.
- Permit and inspection: We pull the plumbing permit with the city and meet the inspector on site. You get a signed-off permit for your records, which matters when you sell the house.
- Old tank removal: We drain, disconnect, and haul away your old tank at no extra charge. The utility area gets swept clean, and we leave the new unit ready to run.

Tankless water heater installation schertz TX explained
A tankless unit is a 20-year appliance, so the install matters as much as the brand. We size it right, vent it to code, and test every connection before we leave.
Tankless water heater installation schertz TX means mounting a compact unit on your wall, running a dedicated gas line or 240-volt circuit, and routing stainless steel venting through the roof or sidewall. Unlike a tank, it heats water only when you open a faucet, so you're not paying to keep 50 gallons hot all day. We size the unit by flow rate, check your gas meter capacity, and pull the permit before we cut anything.
Most Schertz homes we see are 15 to 30 years old with original 40 or 50-gallon tanks nearing failure. When yours starts rumbling or leaking, you're choosing between another tank and an on demand water heater installation schertz TX upgrade. We walk you through the real numbers: upfront cost, monthly savings, and how long the unit lasts. If your home has hard water, we'll also talk about a water softener to protect the heat exchanger.

- What it is
- A wall-mounted unit that heats water on demand.
- When it helps
- When your tank is old, undersized, or leaking.
- What you get
- Endless hot water and lower monthly gas bills.
Our tankless installation process
Every install follows the same five steps. You'll know what's happening and when, from the first call to the final test.
Tools and methods we use
Each method answers a different question. Together they leave very little to guess.
Cuts copper pipe cleanly and solders joints for water lines. We use the torch only where code allows and keep a fire extinguisher within reach.
Checks incoming gas pressure and water pressure before we connect the unit. If gas pressure is low, the tankless unit won't fire reliably, so we test first.
Sniffs out gas leaks around new fittings and confirms water lines are tight. We test every connection before we leave the property.
Inspects the main line when the tankless condensate drain ties into existing waste plumbing. It tells us whether the line can handle the extra flow.

How tankless installation works in Schertz
Schertz sits in Bexar County, and most homes here were built between 1985 and 2010 with 40 or 50-gallon tanks in the garage. The climate is mild, but we do get freezing nights in January and February that split exposed pipes in garages and attics.
Schertz Heights
Older homes here often have undersized gas meters. We check capacity before installing a high-BTU tankless unit and coordinate upgrades when needed.
Cibolo Valley Ranch
Newer construction with PEX tubing and modern gas lines. Tankless installs here are usually straightforward garage swaps.
Northcliff
Larger lots with detached garages. We sometimes run longer vent and gas runs, which affects the install timeline and cost.

PhotoFrom failing tank to endless hot water
Before: A Cibolo family had a 12-year-old 50-gallon tank that rumbled and left rusty water in the morning. Two showers at once dropped the temperature to lukewarm. They were scheduling showers around each other and dreading a leak.
After: We installed a 199,000 BTU Navien gas tankless unit with new venting and a dedicated gas line. Now they run two showers, the dishwasher, and the washing machine at once with no temperature drop.
Electric to gas conversion in Universal City
Before: A homeowner had an aging electric tank in a hallway closet. It took up space, recovered slowly, and tripled their electric bill in winter. They wanted gas but didn't know if the meter could handle it.
After: We ran a new gas line from the meter, installed a Rheem tankless unit on the exterior wall, and removed the old tank. The closet became a pantry.
Two-unit install for a rental property
Before: A Schertz property manager had four units with old tanks failing one by one. Tenants were calling about cold showers, and emergency repairs were eating into the budget. He wanted a long-term fix.
After: We installed two Rheem tankless units to serve the four units, ran new gas lines, and vented through the sidewall. All four units passed inspection in one day. Emergency calls stopped, and the manager now budgets for annual descaling instead of tank replacements.
Problems a tankless installer near me schertz solves
Most people call us because their old tank is failing or their hot water can't keep up.
Running out of hot water during showers
Family members wait 30 minutes between showers, and morning routines fall apart. A tank that can't keep up is undersized for your household.
Rusty water and popping sounds from the tank
Sediment buildup and a corroding anode rod mean the tank is near failure. If it bursts, you're looking at water damage and an emergency call.
High gas bills from standby heat loss
A tank keeps 40 to 50 gallons hot 24 hours a day, even when you're asleep or at work.
No space in the garage or utility closet
A bulky tank eats up floor space you could use for storage, a freezer, or a workshop. It also blocks access to other equipment.
Why Schertz homeowners upgrade to tankless
A tankless unit changes how your whole house uses hot water. Here's what you actually get when we install one.
Endless hot water
You'll never run out mid-shower again.
Lower utility bills
Tankless units use 20 to 30 percent less energy than a standard tank because they only heat on demand.
Frees up garage space
A wall-mounted tankless unit is about the size of a carry-on suitcase.
Lasts twice as long
Tankless units run 20 years with annual descaling, compared to 8 to 12 for a tank.

What Schertz homeowners say
Our old 50-gallon tank finally rusted out. Pro Plumbing Schertz came out the next morning, showed us three tankless options, and had a Navien unit installed by 4 p.m. The garage stays cooler now and we haven't run out of hot water once, even with three kids showering back to back.
We switched from electric to a gas tankless unit. They ran a new gas line from the meter, pulled the permit, and passed inspection on the first try. The technician walked me through descaling and even labeled the shutoff valve.
I manage four rental units and needed tankless replacements done fast. Pro Plumbing Schertz installed two Rheem units in one day and handled all the venting. They cleaned up each unit and sent me photos of the finished work. Tenants stopped calling about cold showers.
