Commercial Water Heater Services

Commercial Water Heater Repair

Many problems do not need a new unit. We test the thermostat, burner or elements, gas valve, anode rod and relief valve. If a repair will hold, we fix it. If the tank itself is failing, we tell you straight and quote the replacement.

Replacement and New Installs

A commercial heater has to keep up with every sink, dishwasher and shower running at the same time. We size the new unit for your peak demand, not just the old nameplate. We install top brands like Bradford White and Rheem, and we haul the old unit away.

Commercial Tankless Systems

Tankless units heat water as it flows, so they do not run out the way a tank can. They also free up floor space in a crowded mechanical room. For high demand, several units can be linked to work together.

Restaurants and Commercial Kitchens

Kitchens need hot water for handwashing, dish machines and cleanup, all day long. When a gas heater goes in, the gas line has to carry it along with the cookline. We check that too, through our commercial gas line plumbing service.

Flushing and Maintenance

Houston water carries a lot of minerals. Over time they settle as scale in the bottom of the tank, which wastes energy and wears the tank out sooner. A regular flush keeps the unit working and helps you avoid an emergency replacement.

Tank or Tankless for Your Building?

There is no single right answer. It depends on how much hot water you use and when you use it.

✔Tank units store a large supply, which suits short, heavy bursts of demand.
✔Tankless units give a steady flow with no waiting for a tank to recover, and they take up less space.
✔Gas or electric depends on what your building already has and what it can carry.

We look at your fixtures, your busiest hours and your existing gas and electric service, then lay out the options and costs in writing. The U.S. Department of Energy also publishes efficiency guidance for commercial gas water heaters if you want to compare models.

Keeping Your Doors Open During the Work

A water heater swap should not close your business for the day. We schedule the work around your hours, and after-hours and weekend work is available. We coordinate with property managers so tenants know what to expect.

New installs and replacements need a permit and inspection from the City of Houston or your local municipality. We pull the permit and schedule the inspection as part of the job.

How a Commercial Water Heater Job Runs

✔We look at the unit, your demand and the space, then give you an upfront quote.
✔We pull the permit before the old unit comes out.
✔We install or repair the heater, then test the gas, venting and relief valve.
✔The inspector signs it off and we confirm hot water at your fixtures.
✔You get a clear invoice and photos of the work for your records.

Commercial Water Heater FAQs

Can you replace our water heater without closing the business?

Yes. We schedule the work around your hours, including nights and weekends, so your kitchen, office or building stays open.

Should we repair our commercial water heater or replace it?

If the tank is sound, a repair to the thermostat, burner, element or valve is often enough. If the tank is leaking or badly scaled, replacement is usually the better value. We test first and tell you which one makes sense.

Is tankless a good fit for a restaurant or busy building?

It can be. Tankless units give a steady supply and save space, and several can be linked for high demand. We look at your peak usage and your gas service before we recommend it.

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

Yes. Replacements and new installs need a permit and an inspection from the City of Houston or your local municipality. We pull the permit and schedule the inspection.
