Commercial Water Heaters in Houston

When a house loses hot water, one family waits. When a restaurant or a salon loses it, the business stops. Commercial heaters are larger, they often work in pairs, and a circulating pump is what gets hot water to the far end of the building.

Nick's Plumbing & Air Conditioning installs, repairs, and maintains commercial water heaters in Houston. We work on gas and electric storage heaters and on tankless units used for business hot water.

Heaters and Parts We Service

• Storage heaters - The tall tanks in a mechanical room, gas or electric, including the flue, the gas valve, and the relief valve
• Tankless units - Wall-mounted heaters sized for a kitchen or a restroom group, including the vent and the gas or electric supply
• Pairs and manifolds - Two heaters piped so one can carry the building while the other is serviced
• Circulating pumps - The pump that keeps hot water moving so the far sink is not waiting on a cold slug of water
• Not a comfort-heating boiler - Building heat boilers are a different system. If the problem is domestic hot water, this is the right page

When a Commercial Heater Is Failing

• Hot water runs out mid-shift - The tank is undersized, the elements or burners are weak, or sediment has stolen the storage
• Water is rusty or smells - The tank is corroding. Flushing may buy time. A leaking tank needs replacement
• The far sinks take forever - The circulating pump or a check valve on the loop has failed. The heater itself may be fine
• A puddle at the heater - The tank, a fitting, or the relief valve is leaking. Shut the water and the gas or breaker if you can do that safely, then call
• Age - Many commercial heaters need replacement somewhere around 8-12 years, sooner in a hard-water kitchen that has never been flushed

Commercial Water Heater Cost in Houston

Commercial water heater work at Nick's Plumbing typically costs $1,800-$19,000. The range is that wide because a repair on a single tank and a replacement of a large heater, or a pair of them, are different projects. Size, fuel, venting, and whether the circulating loop has to be rebuilt all change the price. We confirm the number before any work begins.

A leaking pipe that is not the heater belongs on our repair page. A new heater as part of a build-out is coordinated with installation. Gas supply to the heater is gas line work when the piping itself is the problem.
