Tankless Water Heater Experts

On-demand hot water — repaired right.

Tankless water heaters, also known as on-demand water heaters, function only when needed. Unlike traditional water heaters, which continuously heat large amounts of stored water, tankless models heat water only as it flows through the unit — saving energy and space.

Not just any plumber can perform tankless water heater repairs in Little Rock — you need an experienced contractor. BR McGinty's licensed plumbing technicians will diagnose and repair any tankless water heater issue. We work with all brands, including Noritz, Navien, Rheem, Rinnai, GE, Bosch, EcoSmart, Powerstar, Steibel Eltron, State, and more.

Common Problems

Common tankless water heater problems we diagnose and repair.

Overload
Too many simultaneous hot water uses can overwhelm the unit, causing performance issues. If this happens frequently, consider upgrading your system or adding a second unit.
Mineral or sediment buildup
Hard water can lead to scaling and blockage in pipes, affecting water pressure and temperature. Regular maintenance is essential to prevent these issues.
Blocked air supply or exhaust
Error codes may indicate blockages in the air supply or exhaust. Check that vent pipes are properly connected and free from obstructions.
Flame or ignition failure
If the flame fails to ignite, check the gas supply, valves, and connections. Our team can diagnose and resolve issues related to electrical components or gas lines.
Repair or Replace?

Preventive maintenance can extend your system's lifespan, but it won't last forever.

Choose tankless water heater repair when:

  • The issue is a specific component like a sensor, igniter, or heat exchanger
  • Your unit is within its expected lifespan (20+ years for gas, 7–10 for electric)
  • Repair costs are reasonable compared to replacement
  • Regular maintenance has been performed and the unit is in overall good condition

Consider tankless water heater replacement when:

  • Your gas unit is nearing 20 years or your electric unit is approaching 10 years
  • The unit struggles with high demand and can't keep up with your household
  • Repairs are impractical or costly compared to a new system
  • You want to upgrade to a higher-efficiency inverter-driven system

Converting from a traditional tank to a tankless system might not always be the best choice. Our team can help you select the right replacement water heater for your home or business.

Common Questions

Frequently asked about tankless water heaters.

Honest answers from our licensed plumbers.

How does a tankless water heater work?
Tankless water heaters use natural gas or propane to heat water on demand. When you turn on a hot water faucet, the heater begins warming the water as it passes through the heat exchanger. Once you turn off the faucet, the unit shuts down and consumes no energy.
How long do tankless water heaters last?
Gas-powered tankless water heaters typically last 20+ years, while tankless electric units usually last 7 to 10 years. Proper maintenance can help extend the lifespan of either type.
Can I install a tankless water heater myself?
Installing a tankless water heater requires the expertise of a trained professional. DIY installation poses safety risks and may not meet regulations. BR McGinty provides leak-free connections for gas or propane units, and we offer a one-year installation warranty.
Do you offer emergency tankless water heater repair?
Yes. Hot water is a necessity for more than just bathing — you also need it for laundry, cleaning dishes, and more. We offer emergency plumbing services and respond quickly when your system fails.
