Eemax Electric Tankless Water Heaters

Eemax electric tankless water heaters deliver compact, on-demand hot water for sinks, bathrooms, kitchens, whole-home applications, and hot water booster installs. Shop point-of-use models, 120V and 240V tankless units, HomeAdvantage II whole-home heaters, FlowCo, LavAdvantage, MiniTank, and AutoBooster options for residential and light commercial hot water needs.

Shop by application

  • Point-of-use tankless water heaters: compact units installed close to a sink or fixture to reduce hot water wait time
  • Whole-home electric tankless: higher-output 240V models for multiple fixtures when electrical service and temperature rise allow
  • Lavatory and handwashing: LavAdvantage and SPEX-style models for restrooms, hand sinks, and small-demand applications
  • Mini tank water heaters: small storage options for fast hot water at remote sinks or low-demand fixtures
  • AutoBooster: booster units designed to improve hot water capacity from an existing tank water heater

How to choose an Eemax water heater

  1. Start with the fixture: single hand sink, kitchen sink, bathroom group, or whole-home demand will determine the right model size.
  2. Confirm voltage: many smaller point-of-use units are 120V, while higher-output tankless water heaters typically require 240V service.
  3. Check temperature rise: colder incoming water requires more power to reach the same outlet temperature.
  4. Match flow rate: compare your fixture GPM with the unit’s performance at your needed temperature rise.
  5. Plan electrical requirements: verify breaker size, wire size, amperage, and panel capacity before ordering.
  6. Install for service: leave access for maintenance, follow the Eemax manual, and use qualified electrical and plumbing help when required.

Use filters to narrow by voltage, application, kW rating, series, and installation type. Not sure which Eemax model fits? Share the fixture type, incoming water temperature, desired hot water temperature, flow rate, and available electrical service and we will help confirm the best match.

Pro tips: Electric tankless water heaters must be sized by flow rate and temperature rise, not just by fixture count. Before buying, confirm voltage, breaker space, wire size, and amperage with the installation manual. For best performance, install the unit close to the fixture, flush debris from water lines before startup, and use scale control or filtration in hard-water areas. Not sure which Eemax unit fits? Send us your fixture GPM, incoming water temperature, and electrical service and we will help dial in the right model.
