Gas Hot Water Systems
Upfront pricing, no hidden costs.
What Is a Gas Hot Water System?
Gas hot water systems use either natural gas or liquefied petroleum gas (LPG) to heat water, available in two primary types:
- Storage Systems: Store heated water in a tank, ready for use at any time.
- Instantaneous Gas Hot Water Systems: Also known as instant or continuous hot water systems, these units heat water only when needed, providing a constant flow without storing it.
These systems run on either natural gas, connected through local gas lines, or LPG, which comes in delivered tanks from local suppliers.
Pros and Cons of Gas Hot Water Systems
Cost Efficiency
While gas hot water systems may have higher upfront installation costs due to more complex setup, they offer lower ongoing operating expenses compared to electric water heaters. Gas rates typically do not fluctuate based on usage time, making it a cost-effective option over time.
Reliability
Gas hot water systems operate through a pilot light, allowing them to function even during power outages. They are generally more energy-efficient than electric options. However, gas tanks may have a slightly shorter lifespan than electric tanks, impacting the warranty duration.
Environmental Impact
Gas hot water systems produce fewer emissions than traditional electric systems, heating water faster and more efficiently. This makes them ideal for larger households needing consistent hot water.
Common Issues with Gas Hot Water Systems
No Hot Water
Available
If you’re experiencing a lack of hot water, start by checking the gas supply line to ensure it's on. Verify if the pilot light is lit; if not, try relighting it. When the pilot light won't stay on, the issue may lie with the thermocouple, a safety device signaling the gas valve when the pilot is lit. If this is malfunctioning, it could prevent gas flow to the burner, leading to no hot water.
Limited Hot
Water Supply
If hot water is available but runs out quickly, the issue may be with the thermostat setting or faulty gas valves that need replacement.
Gas Leaks or
Water Leaks
For any suspected gas leak, turn off the gas supply and leave the area. Contact The Plumbing and Electrical Doctor immediately for professional assistance. Water leaks, on the other hand, may require replacing parts like the flue piping or even the entire tank if severe.
Gas Hot Water System Maintenance
Proper maintenance can extend the life and efficiency of your gas hot water system. Key maintenance steps include:
- Insulation to Minimize Heat Loss
- Insulate pipes with foam pipe insulation, and cover the tank sides with an insulation blanket, leaving the top portion uncovered for proper airflow.
- Regular Tank Flushing
- Flushing the tank helps prevent sediment buildup, which can cause inefficient heating and lead to corrosion over time.
- Inspection of Leak-Prone Parts
Regularly check the following components for leaks or other issues:- Cold and Hot Water Inlets: Ensure secure, snug connections to prevent leaks.
- Pressure Relief Valve: If you notice pooling water below the tank but no tank damage, check the thermostat settings and ensure water pressure is within the 50-60 psi range.
- Drain Valve: If leaks occur here, flush the heater and replace the valve if necessary.
