Smell gas near a water heater? Leave the building first and take staff and customers with you. Don't flip switches, start equipment or light anything. Once outside, call 911 or Atmos Energy, then call us at (817) 755-5621.

Tank, tankless or boiler-style?

Storage tanks keep a reserve of heated water, so they handle sudden big draws like a dish machine filling. They're the simplest swap when the room, gas supply and flue already fit.
Tankless units heat water as it flows. Several can share a manifold, keeping hot water flowing while one is serviced. They need a large gas supply and regular descaling, since minerals coat the heat exchanger.
Boiler-style systems pair a hot water supply boiler with a separate storage tank and a circulating pump. Larger apartment buildings and laundromats use them when demand outgrows one tank.

Electric units suit buildings without gas or a vent route; an electrician confirms the panel can carry large ones.

Sizing to your busiest hour

Size comes from peak-hour use, not the old tank's label: storage, recovery (gallons heated per hour) and temperature rise, largest in winter when street water is coldest. Peaks differ by business:

Restaurants and bars: hand sinks, the three-compartment sink, prep and mop sinks, and the dish machine. A high-temperature dish machine uses a booster heater for the sanitizing rinse.
Offices: lavatories and a break room; a small tank or point-of-use unit often covers it.
Salons: shampoo bowls running back to back all day.
Laundromats: rows of washers calling for hot water together on weekend mornings.
Apartments: the morning shower rush, usually with a recirculation loop so far units don't wait long for hot water.

Undersize it and staff run out mid-rush; oversize it and you pay to heat unused water.

Gas line and venting

A bigger or more efficient heater often needs more gas. We total the BTU input on the line, measure the run from the meter and check pipe size against the Fuel Gas Code. A higher total load may need a larger Atmos Energy meter, so we flag it early. See also restaurant gas line installation.

Fort Worth inspectors look for a sediment tee after the shut-off at each water heater, a separate shut-off for every appliance, attic and rooftop valves rated above 145 degrees, and new piping holding its test on a diaphragm gauge.

Standard units vent through a metal flue. Condensing units use the plastic or stainless steel vent pipe the manufacturer specifies and produce acidic condensate, so they need a nearby drain and sometimes a neutralizer. If a heater leaves a shared flue, the remaining appliances get a draft check.

Code items and the permit

Fort Worth requires a plumbing permit to install or replace a water heater; the plumber doing the work pulls the permit and books the inspection. The city enforces the International Plumbing and Fuel Gas Codes with local amendments. Common items:

Hand sink temperature. Public restroom lavatories get tempered water (85°F to 110°F) through a temperature-limiting device listed to ASSE 1070 or an equivalent standard. Texas food rules also require at least 100°F at food-business hand sinks.
Expansion tanks on a storage heater's cold supply wherever a check valve, backflow preventer or pressure-reducing valve traps expanding water.
Relief valves. Each storage heater's temperature and pressure relief line runs full size, untrapped, to a visible spot like a floor sink, pan or outdoors.
Drain pans where a leak would damage the space below.

The federal efficiency standard

A U.S. Department of Energy rule from October 2023 requires most commercial gas water heaters manufactured on and after October 6, 2026 to reach 95 percent thermal efficiency for storage models and 96 percent for tankless units and hot water supply boilers (smaller residential-duty models have their own standard), which in practice means condensing designs. Electric commercial heaters weren't changed.

Status, October 2026: a policy statement issued May 5, 2026 says DOE won't seek civil penalties for covered gas models manufactured before October 6, 2027. In June 2026 the U.S. Supreme Court sent the legal challenge back to the appeals court, so the rule could still change. Installed heaters can keep running and be repaired, but check now whether your room can take a condensing unit.

Planning a replacement to limit downtime

Survey first. Read us the make, model and age from the rating plate when you call; we check the room, gas, flue and drains.
Order ahead. Commercial models aren't always stocked, so we order before removing the old unit.
Swap in a quiet window, before opening or after closing. Buildings with two heaters can run on one during the work.
Start-up and inspection. The heater is purged, lit and set, safety devices are tested, and a city inspector checks the work.

From Riverside we serve kitchens in the Stockyards, Sundance Square, Magnolia Avenue and West 7th, and businesses citywide. See commercial plumbing and our coupons ($150 off a new water heater).

Commercial water heater questions

Do I need a permit to replace a commercial water heater in Fort Worth?

Yes, even for a like-for-like swap. The plumber doing the work pulls the permit, and a city inspector checks the gas connection, venting and relief valve piping.

What size water heater does a restaurant need?

Fixtures and the busiest hour matter more than seat count. We total peak use at the sinks and dish machine, then match storage and recovery to winter water temperatures.

Do new commercial gas water heaters have to be condensing?

The DOE standard for models made from October 6, 2026 sets levels that condensing designs meet, but DOE won't seek penalties for covered models made before October 6, 2027, and in June 2026 the U.S. Supreme Court sent the legal challenge back to the appeals court.

Can tankless heaters replace our commercial tank?

Often, with one large unit or several on a manifold. Expect a larger gas line, new venting, a condensate drain and a descaling schedule.

What if the heater leaks during business hours?

Close the cold-water valve to the heater, turn off its gas or power, and call (817) 755-5621. For water you can't shut off, we send our on-call plumber right away, at any hour.
