Instant Hot Water. Right Where You Need It.
Tired of waiting for hot water to reach your sink? The ThermoMate ES600 6-Gallon Mini Tank Water Heater brings hot water directly to the point of use — eliminating long pipe runs, reducing water waste, and improving everyday convenience.
Compact yet powerful, this 120V electric mini tank is ideal for under-sink installation in kitchens and bathrooms, as well as garages, workshops, RVs, cabins, basement bars, and small commercial spaces.
Built for Everyday Performance
Powered by a 1500W INCOLOY 800 stainless steel heating element, the ES600 heats water quickly and efficiently while offering superior corrosion resistance compared to traditional copper elements. Whether used as a standalone heater or as a booster for your main system, it delivers dependable hot water with fast recovery.
The 6-gallon capacity is perfectly sized for handwashing, dishwashing, and light-duty applications — giving you comfort without the bulk of a full-size tank.
Durable Inside and Out
The interior tank is protected by a porcelain enamel glass lining, designed to resist rust, scaling, and high-temperature wear. This added protection helps extend the lifespan of the heater while reducing maintenance concerns over time.
The durable metal housing adds another layer of reliability, making it suitable for utility spaces and demanding environments.
Adjustable Comfort, Built-In Safety
Customize your water temperature between 90°F and 150°F using the adjustable thermostat. Whether you need mild warmth or hotter water for cleaning, you stay in control.
For added peace of mind, the unit includes:
- UL Listing for safety compliance
- ASME/ANSI/CSA-approved temperature & pressure relief valve
- High-temperature limit protection
- Independent drain port for easier servicing
Engineered to meet North American residential standards.
Compact Design. Flexible Installation.
With a space-saving footprint, the ES600 fits comfortably under most sinks. It operates on standard 120V power and is designed for hardwired installation (optional power cord included). A dedicated 15 AMP breaker is recommended for optimal performance.
Simple for licensed electricians and experienced DIY homeowners alike.
A Smarter Way to Get Hot Water
