Tankless Water Heater Repair, Replacement & Installation
The plumbing experts at BR McGinty can diagnose, repair, replace, and install all brands of tankless water heaters. Our licensed plumbers have 75+ years of collective experience and provide Central Arkansas residents with the best service possible.
There are two common types of water heaters: tank-type and tankless. Both come in gas and electric options. We recommend tankless for most situations — but our experts will assess your specific needs and help you choose the best fit.

Stores large amounts of water in insulated tanks and uses a coil or burner to keep water heated constantly — even when no hot water is needed. Energy is consumed around the clock.
Tankless Water Heater
Heats water only when needed. When flow is detected, water passes through the heat exchanger and is heated on demand. When there's no demand, the unit shuts down and uses no energy.
On-Demand Hot Water
How Do Tankless Water Heaters Work?
Tankless water heaters, also known as on-demand water heaters, function only when needed. Unlike traditional water heaters that continuously heat large amounts of stored water, tankless models heat water only as it flows through the unit.
These 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.

Expert Repair Service
Tankless Water Heater Repair
Hot water is essential in your home. Not just any plumber can perform tankless water heater repairs — you need an experienced contractor. BR McGinty's licensed plumbing technicians will diagnose and repair any issue. We work with all major brands:
Common Problems We Fix
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 leads to scaling and blockage in pipes, affecting water pressure and temperature. Regular maintenance prevents these issues and ensures optimal performance.
Blocked Air Supply or Exhaust
Error codes may indicate blockages in the air supply or exhaust vents. Check that vent pipes are properly connected and free from obstructions to avoid combustion problems.
Flame or Ignition Failure
If the flame fails to ignite, the problem may be with the gas supply, valves, connections, or electrical components. Our team can diagnose and restore proper functionality.
Don't Wait
Signs You Need a New Water Heater
Preventive water heater maintenance can extend your system's lifespan, but it won't last forever. Gas-powered tankless units typically last 20+ years, while electric tankless units usually last 7 to 10 years. If your unit is nearing end-of-life or struggling with high demand, consider upgrading.
Keep your eyes and ears open for these warning signs before a small problem becomes a costly one:
Rust on Exterior
Rust on the outside means water is escaping the tank, causing heat retention issues.
Rusty-Colored Water
The glass lining inside the tank has likely broken, allowing rust into your water supply.
Decreased Water Pressure
A drop in pressure means the tank is no longer airtight and heat is escaping.
Clicking or Popping Sounds
Unusual noises — especially with low pressure — indicate a broken dip tube releasing cold water into hot.
