## Description

ThermoMate Electric Tank Water Heater, 8.0 Gallon Point of Use Instant Small Hot Water Heater 120V 1440W, Wall or Floor Mounted, Plug-in to Use, UL Listed ES800 - desertcart.com

Review: great - This small tankless water heater works great for a sink or small space. It heats up quickly, is compact, and was easy to install. It doesn’t take up much room and provides hot water almost instantly. Great value for the price and perfect for light everyday use.
Review: Great for a kitchen - We got the 2.5 gallon for under the kitchen sink as we were tired of wasting water waiting for it to get hot. We plugged it into an outlet that has a switch and I turn it on when needed, it only takes about 5 minutes to get really hot. It took a few days of experimenting because if you turn the water on and off, the cold comes into the tank each time it is turned off and cools down your hot water. Because of this I get everything ready first, and then leave the water running at a strong trickle while doing the dishes. This is wonderful - I am able to clean all the dishes before running out of hot water. This works really well for the two of us, but if you have lots of dishes it may not be enough volume without waiting a few minutes for it to heat up a new batch of water. Very very happy, and we are saving a lot of water now.

## Questions & Answers

**Q: How Do Point-of-Use Electric Mini-Tank Water Heaters Work?**
A: The unit connects directly to a cold water source, which fills the tank and is heated with an electric heating element to the desired temperature until it's ready to be used. The water is released when a faucet or fixture is opened.

**Q: What applications are point-of-use electric water heaters best for?**
A: Designed for single applications and small load requirements, these water heaters are commonly located under sinks, in small apartments, and in additions like side rooms and garages.

**Q: What type of point-of-use electric water heater should I buy?**
A: Mini-tank water heaters preheat a small amount of reserved water until it's ready to be used. Tankless water heaters heat water on demand as it travels through electrical heating elements within the unit.

**Q: What will happen if I connected this water heater to my hot water line?**
A: The cold water in the line will flow into the tank first and mix with the hot water there. The mini tank water heater will turn on heating until the hot water from your main water heater eventually reaches the mini tank

**Q: Can this mini tank water heater be used for shower?**
A: A mini-tank water heater is not intended to service a shower because it requires a larger flow from 1.5gpm to 2.5gpm, while these mini tank capacity range from 1.3 gallons, 2.5 gallons and 4 gallons, to max 6.5 gallons.
