The most recognizable unit - a tall, round water tank filled with cold water. The water is heated inside the tank and distributed throughout your home via hot water pipe distribution. Typically fueled by natural gas - the most economical option to heat them.
Typical Life Span - 8 to 12 Years with Routine Maintenance.
The modern, energy-efficient alternative to a traditional storage tank water heater. Tankless water heaters are compact and save valuable floor space in your home. When you run hot water from your tap or shower, cold water passes through the unit and the water is rapidly heated via a heat exchanger. The Tankless Water Heater only heats the water you need, when you need it.
Typical Life Span - Up to 20 Years with Routine Maintenance.
Typically, a conventional storage tank water heater is paired with an electric heat pump, and the heat pump is utilized to warm the tank water. This system option is more efficient and cost effective than a traditional tank water heater, but this option does depend on your home and installation space.

Water leaks of any kind are serious but if you notice water leaks around your water heater or in the pan underneath, repairs are necessary to prevent further damage to the unit or your home.

Discolored or rusty water appearing from hot water taps - sinks, bath or shower, even on fabrics in the washing machine indicate corrosion inside your water heater and it should be addressed.

Strange sounds like gurgling, rumbling, popping, or pinging may indicate water sediment buildup, water pressure fluctuations, or misfiring/malfunctioning heating elements.

Yes. A certified plumber will present options relevant to your current water heater, the existing plumbing and electrical systems and your usage & budgetary considerations.
A number of factors come into play, but the seriousness of the specific issue and the overall age of the water heater are primary. For example, consistent or repetitive water leaks from your unit mean more of a structural failure within the tank versus a specific part like the heating element needing to be serviced or replaced. Our team will be able to evaluate your system and communicate best recommendations for your decision making process.
