Why Sacrifice Bathroom Space for Reliable Hot Water in Your Shower?

• Same hot water capacity

Unlike traditional storage water heaters with larger tanks and slower heating, Esio's innovative technology delivers the same hot water capacity in a compact unit. Even with two bathrooms in use, enjoy stable, uninterrupted hot water, eliminating temperature fluctuations.

Never Endure Sudden Water Temperature Drops Again.

Are the sudden drops in water temperature while you shower on a rainy day making you want to scream? It's not OK, you deserve better. It's time to upgrade your shower experience.

Discover the Esio Difference. Our water heaters incorporate the USA brand Therm-O-Disc surface mount thermostat. This advanced technology guarantees precise water temperature control within the heater and prevents scale build-up that can impact thermostat performance.

Why Compromise for Slow When You Need it Fast?

Your time is valuable, and waiting for hot water can be frustrating. Our 4.5kW Japan-imported Incoloy nickel-iron-chromium alloy 800 heating element reduces heating times by up to an incredible 40% compared to a 3kW element.
