Common GSW Water Heater Issues

Like any appliance, GSW water heaters can experience issues over time. Here are some common problems and their potential causes:

1. No Hot Water

If your water heater is not producing hot water, the issue may be related to the gas supply, pilot light, or heating elements. In some cases, a faulty thermostat or a tripped circuit breaker may be the culprit.

2. Insufficient Hot Water

If your water heater is not providing enough hot water, it may be due to sediment buildup in the tank, an improperly sized unit, or a malfunctioning heating element. A professional technician can diagnose and resolve these issues.

3. Leaking Tank

A leaking water heater tank can be caused by several factors, including corrosion, excessive pressure, or a faulty pressure relief valve. In some cases, the tank may need to be replaced, while in others, a simple repair may suffice.

4. Strange Noises

Unusual noises coming from your water heater may indicate sediment buildup, water hammer, or issues with the heating elements. Regular maintenance can help prevent these problems and ensure your water heater operates efficiently.

GSW Water Heaters: Types and Features

1. Flame Guard® Safety System

The Flame Guard® Safety System is designed to reduce the risk of accidental fires involving flammable vapors from products such as gasoline, paint thinner, and solvents. This innovative system ensures that your water heater operates safely, preventing potential hazards.

2. Direct Vent

Direct vent water heaters allow for a sealed combustion process to take place. This means that combustion air comes in from the outside, and flue gases exit to the outside through a 2-pipe venting system. This design is ideal for tightly built new homes, ensuring proper ventilation and safety.

3. Power Direct Vent

The Power Direct Vent water heater features a sealed combustion chamber, an ultra-quiet blower, and state-of-the-art Robertshaw® gas control for highly accurate temperature control. Its Flammable Vapor Ignition Resistant (FVIR) design prevents flammable vapors from entering and igniting the system. This type of water heater is suitable for homes that require a higher level of safety and efficiency.

4. SuperFlue™ FVIR Compliant

SuperFlue™ gas water heaters come with a built-in blower, allowing through-the-wall or through-the-roof venting up to 50 feet to the exterior of the home. This feature is ideal for conversions from electric to gas water heaters, providing a seamless transition process.

5. Light Duty Commercial Power Vented

Similar to the SuperFlue™ model, the Light Duty Commercial Power Vented water heater also features a built-in blower for through-the-wall or through-the-roof venting up to 50 feet. This model is designed for commercial applications, ensuring optimal performance and durability.
