ThermoMate ES800 8 Gallon Electric Tank Water Heater – 120V, 1440W, UL Listed

Fast, on-demand hot water with a compact footprint

Meet the ThermoMate ES800, a point-of-use electric tank water heater designed for small spaces. With an 8.0-gallon capacity and a 1440W, 120V plug-in setup, it delivers hot water quickly where you need it most—kitchens, bathrooms, RVs, cabins, or workshops. The unit’s compact form helps you unlock under-sink or cabinet spaces that once felt crowded, while still providing reliable warmth when you turn on the tap.

Designed for everyday use, the ES800 offers adjustable temperature control from 50°F to 149°F. A thick, CFC-free polyurethane layer—30 mm deep—reduces heat loss, helping warmth linger longer between uses and reducing the need for constant re-heating. This focus on insulation supports a more comfortable experience at the sink without requiring extra energy in between uses.
