Our Services
Water Heating Support for Commercial Properties
Commercial water heaters operate under demands very different from residential systems. High-volume usage, peak-demand periods, and building-specific requirements all affect system performance over time. In busy areas like Anaheim resorts, food service operations place extra strain on recovery rates, while multi-unit properties need consistent temperatures across multiple points of use.
Water Heater Man has focused exclusively on water heaters and water treatment systems for decades. That experience allows us to work confidently with a wide range of commercial configurations, usage profiles, and building layouts.
We provide:
- Water heater installation and replacement
- Water heater repair
- Routine maintenance
Our team serves businesses throughout North Orange County and Gateway Cities Region, helping keep hot water available and daily operations running efficiently.

Can I downsize my water heater to a smaller one for my property?In some circumstances you can, but the job site would have to be properly sized with a water heater sizing guide. Most applications are sized to accommodate the usage of hot water at peak periods during the day. We don’t recommend downsizing your water heater unless all measures are followed and the application is sized properly. Please call for further assistance.

Water heater turning off? Getting error code 110 or 61?
Is your water heater turning off and displaying error code 110 or 61 on your Bradford White UCG100H399? Are you loosing hot water during peak usage times?
The problem could be with your gas pressure.
Gas pressure will fluctuate when all equipment is on in the building. If the gas supply line is small, the water heater may be having issues with the dynamic gas pressures.
- On this particular water heater, the static gas pressure is rated between a minimum 4.5″ wc and a maximum of 14″ wc.
- Dynamic gas pressure should not drop below 1.5”wc of the static gas pressure
- Drops in gas pressures will normally be seen during peak times of usage when all equipment is being used
- If the Dynamic pressure drops below 5”wc the water heater will not operate properly
When testing static gas pressure, you will have to ensure that all equipment is on and running. If you don’t, your readings my not be accurate
Hook up manometer to inlet port on gas valve and get static gas pressure reading
Turn on heater and wait for heater to fire. After 3- 5 minutes while heater is at full fire, check you dynamic pressure. If the pressure drops below 1.5”wc, there is a problem with either the gas supply or size of the gas line.
Double check the gas line size.
Double check the rating on the gas flex, if installed.
Verify the main gas line prior to the tee off for the water heater is sized adequately.
Increase the gas line to the water to a minimum 1 ¼” as close to the heater as possible.
Retest static and dynamic gas pressures.
If the problem persists there many be a different issue causing your loss of hot water.

What is the purpose of a recirculation pump?The purpose of a recirculation pump is to get hot water within about 5 seconds to all faucets supplied by hot water. The recirculation pump is attached to a secondary supply line that is connected to the hot water supply line at the farthest fixture away from the water heater. The recirculation pump then circulates the hot water throughout the entire building so every fixture has hot water within about 5 seconds of opening the faucet. A recirculation pump and recirculation line can save you money on your energy and water bill because the pipes are constantly (when needed as the pump can also be on a timer) hot and you have warm water returning to the water heater. Without a recirculation line, on average, the furthest shower/tub can waste an estimated 12,000 gallons of water a year waiting for the water to get hot. If you don’t have a dedicated recirc line, a dedicated line can be added, but is costly. They now make systems to allow you to have hot water within seconds without running a dedicated recirculation line. These are called Comfort Systems and can be purchased and installed through us.
When It’s Time to Install or Replace a Water Heater
Installing or replacing a commercial water heater involves more than selecting a unit with enough capacity. Demand load calculations, recovery time, physical space, venting requirements, and local code considerations all influence system selection and layout. During the planning phase, we review how your business uses hot water throughout the day and discuss system options that align with those needs.
For aging systems that struggle to keep up or experience recurring issues, replacement may offer an opportunity to reassess capacity or update system design. We explain available configurations, outline realistic considerations, and help you evaluate whether replacement aligns with your operational goals, without urgency-driven sales tactics.
Handling Water Heater Problems in Business Settings
When a commercial water heater isn’t performing as expected, timely evaluation can help reduce operational disruption. Issues such as inconsistent temperatures, reduced output, pressure irregularities, or unusual sounds often point to component wear, sediment buildup, or system imbalance. Our team focuses on identifying the specific cause of the problem and outlining practical repair paths based on system conditions and business needs.
Ongoing Care for High-Demand Water Heater Systems
Routine maintenance supports steady operation in water heaters that experience daily, high-volume use. Many properties across Anaheim and nearby areas contend with hard water, which can accelerate mineral scaling and sediment accumulation within tanks and heat exchangers over time.
Our maintenance typically includes system inspections, sediment management, component checks, and temperature and pressure reviews. In higher-demand settings, such as restaurants, hotels, and multi-tenant buildings, service intervals are often adjusted to reflect actual usage levels and system design.
Supporting Water Quality
Water quality has a direct impact on how commercial water heaters perform over time. Hard water and sediment can reduce heating efficiency and put extra strain on internal components. In many of the properties we service, water treatment systems, such as softeners or filtration units, are used alongside water heaters to help manage these conditions and extend system life.
As part of our service approach, we evaluate how water quality may be influencing system performance. When appropriate, we discuss treatment options that could support long-term operation based on usage demands and existing infrastructure. This combined view allows businesses to address both hot water production and water quality under one coordinated service plan.
