Common Water Heater Service Questions

The best way to tell is if there’s a label, but there are other methods. Gas heaters will have gas lines leading to the unit, with a pilot light near the bottom of the tank (this is sometimes behind a small panel). Electric units often have lights to signal if they’re heating or not and may have electric panels to control the unit. If there is a vent pipe leading from your heater, it’s almost certainly gas-powered.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

Yes, a leaking water heater can damage electrical work. Water can seep into electrical components, causing short circuits, tripped breakers, or even fires. The combination of water and electricity is quite hazardous, so it's crucial to address any leaks immediately to prevent electrical damage and ensure your home’s safety.

While possible, professional assistance is recommended to ensure compliance with local regulations and avoidance of avoidable risks.

It is not recommended that you cut up your old water heater. Doing so poses a safety risk and may expose you to dangerous components inside the heater. If your water heater is too large or heavy to move on your own, call in a professional to handle removal and disposal.
