Gas Tank Water Heaters Canton

What is tankless water heater?

A tankless water heater, or on-demand water heater, provides hot water only when you need it. Instead of storing and reheating water in a tank, it heats water instantly as it flows through the system—giving you endless hot water and saving energy.

These compact units can run on gas or electricity, take up little space, and often last 20+ years with proper care. While the upfront cost is higher than a traditional tank model, homeowners in Canton, GA choose tankless water heaters for their efficiency, reliability, and long-term savings.

At Fast Drains Plumbing, we offer expert tankless water heater installation, repair, and maintenance to keep your home comfortable year-round.

Types of Tankless Water Heaters

Gas-Powered Tankless Water Heaters

If your home is near a natural gas line, you can usually connect your tankless water heater directly. Homes without access will need propane instead. The experts at Fast Drains Plumbing can assess your setup and recommend the best option. Let us handle your gas-powered tankless water heater installation with ease.

Electric-Powered Tankless Water Heaters

You can also choose an electric tankless water heater. These units are usually more affordable and easier to install than gas models. However, gas-powered systems typically heat water faster and can be more cost-efficient to run over time.

How Do Tankless Water Heaters Work?

Tankless water heaters are available in both gas and electric models, depending on your utilities. When you turn on the tap, cold water flows through the unit and is heated instantly by either a gas burner or electric element.

Unlike traditional tanks, there’s no waiting for reheating—hot water is delivered on demand. Electric units can heat around 2–5 gallons in just a few minutes, while gas models can heat up to 9 gallons in the same time, making them faster and more efficient.

Water heater maintenance and replacement

Tankless Water Heater Repairs

Tankless water heaters are generally low maintenance, but issues can still arise over time. If you notice any problems, trust the experienced plumbers at Fast Drains Plumbing to quickly restore your system and keep your hot water running. At Fast Drains Plumbing, our licensed plumbers quickly diagnose and repair tankless water heater problems so you can enjoy reliable hot water without interruption.

Mineral Buildup

Tankless and traditional water heaters alike can suffer from mineral buildup caused by hard water. Excess calcium and magnesium can collect inside the unit, reducing efficiency and damaging components over time. Regular maintenance helps prevent scale from affecting your system.

System Overload

Running multiple hot water fixtures at once can overwhelm your tankless water heater, especially if the unit is undersized for your household. This may cause unexpected shutdowns. Limiting simultaneous use or upgrading to a higher-capacity system—or even adding a second unit—can solve the issue.

Blocked Air Supply or Exhaust

Error codes on your tankless display may point to a venting or combustion air blockage. Check vent pipes for proper connections and clearances. Left unresolved, this can become a fire hazard, so professional inspection is strongly recommended.

Ignition Failure

If your unit won’t ignite, first check your propane or gas supply and ensure both gas and water valves are fully open. If the problem persists, it could indicate a more serious issue that requires a professional plumber to diagnose and repair.

Flame Failure

Flame failure is often linked to gas pressure problems or electrical issues. Simple causes like an empty propane tank or unpaid gas bill should be ruled out first. If those aren’t the problem, call a professional to check for combustion issues, venting blockages, or regulator malfunctions.
