Benefits of Gas Water Heaters

Installing a gas water heater in your home can provide many benefits, including:

  • Continuous operation: Unlike their electric counterparts, traditional gas water heaters with continuously burning pilot lights can usually operate during a power outage.
  • Cost-effective operation: Natural gas tends to be less expensive than electricity, resulting in lower monthly energy bills.
  • Faster heating: Gas water heaters can heat water faster than their electric counterparts, providing a rapid hot water supply.
  • Recovery rate: Gas water heaters are quicker at reheating incoming cold water after hot water is used, reducing wait times between showers or appliance use.

Gas Water Heater Repair

Over time, gas water heaters can develop issues like pilot light malfunctions, sediment buildup, and corrosion, increasing the likelihood of sudden system failures. Our team offers emergency water heater repairs to families throughout Philadelphia, ensuring their systems remain operational. We have experience diagnosing and fixing:

  • Inconsistent hot water: If your gas water heater no longer consistently produces hot water or takes much longer to heat up, there may be an issue with the burner, thermostat, or other components.
  • Strange system noises: Rumbling, popping, or banging sounds coming from the water heater tank can signal sediment buildup or other internal issues that require professional attention.
  • Discolored, rusty water: If the hot water coming from your taps appears rusty or discolored, it could indicate corrosion inside the tank, which may lead to leaks.

Gas Water Heater Maintenance

Annual gas water heater maintenance ensures your system remains in top working order. Our team has experience servicing all gas water heater makes and models, offering thorough tune-ups to flush your system of sediment buildup and keep it functioning properly.

With our Comfort Protection Plan, we help make maintenance easy and affordable by offering members exclusive discounts, priority scheduling, and no extra fees for diagnostic or emergency services.

Frequently Asked Questions


Standard tank gas water heaters typically last between eight and 12 years, while tankless gas water heaters can last 15 to 20 years with routine maintenance.

A tank water heater is ideal for homes with high hot water demand. A tankless model provides energy efficiency and endless hot water on demand, making it suitable for smaller households or those looking to save on utility bills.

During maintenance, a technician inspects the unit, flushes the tank to remove sediment, checks for leaks, tests the thermostat and safety valves, and ensures the burner operates efficiently and safely.
