Buying Guide
What should you consider when choosing an electric water heater deal?
- Flow rate needs: If you frequently run a shower and sink together, opt for higher GPM capacity (Rheem or 12kW+ units). For under-sink use or single faucet tasks, compact 110V models work well.
- Electrical requirements: Tankless heaters often need dedicated circuits (120V vs 240V). Verify available breaker capacity and wiring or consult a pro.
- Space and installation: Wall-mounted units save space; consider vertical orientation recommendations and clearance for exhaust or heat dissipation if applicable.
- Water temperature rise: Devices with higher wattage deliver hotter water faster. Evaluate the expected rise at your typical faucet flow (GPM) to match the right model.
- Safety and durability: Look for IPX ratings, dry-run protection, and leak prevention features. Enamel coating and copper elements can affect longevity and safety.
Frequently Asked Questions
- What size tankless heater do I need for my home? – Choose based on desired GPM and temperature rise; larger homes often require higher wattage and possibly multiple units interconnected.
