Water Heaters FAQs, answered by experts

Not all types of water heaters require a venting system. Electric tankless water heaters don’t use natural or propane gas, so no venting is required. Instead, they use electric burners to heat water quickly and efficiently. However, any system that does use gas or propane will require ventilation.

If your water heater continues to have issues, you may wonder how long an electric water heat lasts. On average, these units last between 10 to 15 years. Following a proper maintenance schedule can help the water heater live to the end of its average lifespan or longer.

Several signs indicate your water heater may be failing or in need of replacement. Key indicators include:

  • Age: A water heater older than ten years is approaching the end of its typical lifespan.

  • Water Quality: If you notice rusty or discolored water from your hot water faucets, or a foul odor similar to rotten eggs or sulfur, it can signal internal corrosion.

  • Unusual Noises: Banging, rumbling, or popping sounds from the tank often mean sediment has built up, causing the unit to overheat.

  • Leaks: Any water pooling around the base of the tank or visible leaks are clear signs of failure.

  • Performance Issues: A decline in performance, such as water not getting hot enough, taking longer to heat up, low water pressure, or decreased efficiency, suggests the unit is struggling.

  • Visible Damage: Obvious rust and corrosion on the exterior of the tank can indicate a more serious internal problem.

While these signs often point to replacement, some issues may be fixable. It's best to consult a professional plumber to diagnose the problem before investing in a new unit.

Replacing facilitates energy savings, decreases repair frequency, and aligns with modern safety regulations, maximizing safety.

You can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations.
