The tankless water heater is among the most valuable modern innovations. Time after time, the technology has proven itself a worthy replacement for standard storage water heaters in both residential and commercial applications.


For a continual, high-volume supply of hot water, nothing can top a commercial tankless water heater. These models promise increased efficiency, energy savings, and cost reductions that outdated storage-based water heaters simply can’t match.

What Is a Commercial Tankless Water Heater?

Just what is a commercial tankless water heater, anyway? As the name implies, these water heaters are indeed tankless. Because there’s no tank, these systems work off of demand. They heat up water as you need it, delivering hot water to a sink, tub, shower, or appliance quickly. Best of all, commercial electric tankless water heaters never run out of hot water. They’re also energy efficient, space-saving, and offer a longer product life than a standard hot water heater. Clearly, tankless water heaters offer many advantages over older models and designs.

Commercial Tankless Water Heater Repair and Maintenance

The average lifespan of a commercial tankless water heater is between 15 and 20 years. If you’re hoping to get the maximum use possible from your unit, be sure to service it regularly. Annual maintenance can help ensure minimal scale backup and keep your water heater running safely and efficiently.


The longer you go between maintenance appointments, the more inefficient your commercial tankless gas water heater can become. This will inevitably raise your energy or fuel bill. You can avoid such issues by scheduling a yearly maintenance appointment with your local Hous Air HVAC Service team.


While commercial electric tankless water heaters are fairly low maintenance, sediment buildup can cause problems. As sediment builds, the volume of hot water is reduced. This can cause problems for your employees, customers, or building tenants, as they’ll perpetually receive less hot water than they need. Issues like this highlight the importance of regular maintenance appointments. If your water heater develops a problem, an Hous Air HVAC Service professional is only a call away.

Types of Commercial Tankless Heater Services

If you’re considering investing in a commercial tankless water heater, you may be curious about ongoing servicing needs. Adding a water softener to your system can help reduce build-up from hard water. If you have especially hard water, you may see staining on sinks, showers, and tubs. Scale build-up, and erosion may also occur.


Hard water can cause problems for storage tank systems because as hard water passes through, the acidity causes minerals in the water to drop to the bottom of the tank. This sediment impacts the efficiency of the heat transfer, leading to premature system failure. The same dynamic is in play with tankless units, but often at a much slower rate. Hard water filtration, periodic inspections, and regular maintenance can address these issues, reduce stress on your system and improve performance.

When build-up reaches a critical point, your tankless system may lock-up. Attempting to reset them without properly addressing the issue, will only result in them locking up more frequently. A flush kit may remove build-up, but if not used correctly, it will not resolve the issue long-term. To ensure your system operates efficiently year round, count on Hous Air HVAC Service’s commercial tankless water repair service any time you experience a leak, shutdown, hot water shortage, or inconsistent water temperatures.
