What it delivers
The Westinghouse ES040A3G 4-Gallon Mini-Tank Water Heater is a mini-tank heater holding 4 gallons, rated at 1.44 kW on 120 volts.
It stores a few gallons of hot water right at the fixture, so the tap runs hot at once instead of waiting for the main heater.
It runs on 120 volts, so no new 240-volt circuit is needed in most installs.
Also on the listing: features: Overheat Protection; material: Glass-Lined; model: ES040A3G.
The listing gives dimensions of 14.96 in (W) x 18.46 in (H), a weight of 21.2 lb and pressure and temperature relief valve x 1 in the box.
