Commercial water heaters work harder than residential units — running longer cycles, handling higher demand, and operating under stricter regulatory requirements. When a commercial water heater fails, the impact ripples through the entire business: no hot water for a restaurant kitchen, an interruption to a hotel’s guest experience, or a shutdown of commercial laundry operations. Barnett Plumbing provides comprehensive commercial water heater services to businesses throughout Marietta and North Atlanta.
Commercial Tank Water Heaters. Large-capacity storage water heaters (50–250+ gallons) designed for high daily demand. Common in restaurants, hotels, multi-unit residential buildings, and office complexes.
Commercial Tankless Water Heaters. On-demand systems that heat water only as needed, offering energy savings and a continuous supply. Increasingly popular in commercial applications where consistent flow is needed throughout the day.
Heat Pump Water Heaters. Highly efficient units that move heat from the ambient air to heat water. An excellent option for large commercial spaces where energy costs are significant.
Booster Water Heaters. Used in commercial kitchens and dishwashing operations to elevate water temperature for sanitizing requirements. Health code mandates specific temperature minimums at the dishwasher — a correctly sized and functioning booster heater is essential for compliance.
One of the most common problems we see in commercial water heater systems is an undersized unit that was installed when a business had different needs. As businesses grow — or as usage patterns change — the original water heater can’t keep up. We assess your current and projected demand and recommend the right sizing to ensure you always have adequate hot water without oversized energy waste.
Barnett Plumbing serves Marietta, Kennesaw, Marietta, Sandy Springs, Woodstock, and surrounding communities. To schedule commercial water heater service or discuss a replacement, call (678) 437-1234 or contact us online. We’re available 24/7 for emergencies.
