Etank 8 Gal. 1440-Watt 120-Volt Plug-In Point of Use Electric Tank Water Heater with 6-Year Warranty

Hello, the 4-Gallon Electric Tank Water Heater cannot be mounted flat; doing so may cause water leakage at the pressure relief valve. We regret to inform you that, at this time, we do not have a design suitable for horizontal installation. Thank you for your inquiry.

Our mini-tank electric water heaters feature a built-in insulation layer designed to prevent internal freezing. During the winter, we recommend powering on the unit 30 minutes prior to use; however, if the unit is to remain unused or disconnected from power for an extended period, we strongly advise inverting the unit to completely drain all the water. Thank you.

GPM means Gallons Per Minute. Also known as "flow rate", GPM is a measure of how many gallons of water flow out of your shower head each minute. For a 4-gallon mini tank water heater at a water pressure of 0.1 MPa, the water flow rate is 1.85 gallons per minute. It can meet the following application scenarios: washing vegetables, washing face, washing hair, etc., where the hot water demand is relatively small, but not enough for showering. Thank you!

Yes, our 8-gallon Mini-Tank Electric Water Heater can be used for a shower.

Please do not put the polyethylene plastic overflow pan under the 8-gallon mini electric water heater, as this may cause leakage or corrosion of the tank. Thank you!

The 8-gallon electric water heater can heat about 7.2-7.5 gallons of water at a time when filled with water. The heating time is related to the amount of water you need and the water inlet temperature. The higher the inlet water temperature, the shorter the heating time will be; conversely, the longer the heating time will be. If the inlet water temperature is 68 degrees Fahrenheit, it will take about 30 minutes to heat the unit full of water to 104 degrees Fahrenheit, and about an hour to heat it to 158 degrees Fahrenheit.Thank you!

We don't recommend using the pump to drain the water. There are water inlet and outlet pipes inside the unit, so please don't use the pump pipes to pump the water out. You can use compressed air to blow air into the water inlet and the water will come out of the water outlet. But you need to control the air intake pressure to prevent excessive air pressure from damaging the liner. You can also let the water flow out naturally; refer to the following steps: 1. Turn off the power and turn on the faucet to release water until it cools down; 2. Close the inlet valve, turn off the faucet, and then remove the inlet and outlet valve connector; 3. Invert the small kitchen treasure and drain it.

To drain the water in the mini-tank electric water heaters, there are two methods for your reference: Method one: 1. Turn off the power and open the faucet to drain the water until the water in the faucet becomes cold; 2. Close the water inlet valve, turn off the faucet, and then remove the inlet and outlet valve connectors; 3. turn the water heater upside down to drain; Method two: 1. Turn off the power and leave the water heater unused for 2 days to allow its internal temperature to cool naturally; 2. Close the water inlet valve, close the faucet, and then remove the inlet and outlet valve connectors; 3. Invert the water heater for drainage.
