Electric Tank Water Heaters

Electric tank water heaters provide reliable hot water by storing and heating a ready-to-use supply. They are popular for straightforward installation, quiet operation, and no need for gas lines or venting. Whether outfitting a new build or replacing an aging unit, you’ll find models from compact 30-gallon units to family-sized 50–80 gallon tanks, typically 240V with dual elements for quicker recovery.

Key benefits:
- Consistent hot water for showers, laundry, and dishwashing without combustion byproducts.
- Lower upfront cost and simpler wiring compared to gas or tankless systems.
- Flexible placement in basements, utility rooms, or closets with a drain pan.

Look for features that boost performance and longevity: thick foam insulation to reduce standby losses, glass-lined or stainless-steel tanks, magnesium anode rods, brass drain valves, and adjustable thermostats. Modern electric hot water heaters may add Wi‑Fi controls, vacation mode, leak detection, dry‑fire protection, and smart demand response. High-efficiency and hybrid heat pump options offer substantial energy savings with top UEF ratings.

Sizing is critical. Match capacity and first-hour rating to household peak demand; a typical family often chooses 50 gallons, while high-demand homes may need 66–80 gallons. Check electrical requirements (dedicated 30–40A circuit, 240V) and verify panel capacity.

Installation tips for a clean, code-compliant setup:
- Use a drain pan with a routed drain, and strap the tank where seismic codes apply.
- Install a thermal expansion tank if required by local code or closed systems.
- Connect a properly sized T&P relief valve discharge line to a safe termination point.
- Add dielectric unions, full-port shutoff, and insulation on hot and cold lines.

Maintain performance by flushing sediment annually, testing the T&P valve, and inspecting the anode every 3–5 years. Explore trusted brands, compare warranties, and review UEF ratings to pick a durable, efficient electric storage water heater.
