What Is Interesting About the mini tank water heater?

No more cold water sandwiching

Ecosmart has a long list of the tankless water heater, yet they opted for some mini-tank water heaters for some glaring problems that cannot be avoided in tankless water heaters. If you consider the cold water is sandwiching issue, that usually occurs when cold water stored in the line comes from hot water. A push back and forth pressure causes cold water to get in between hot water and to go through an outlet at a point making the user surprised and disappointed. With a tank water heater, such problem never occurs.

No need of recirculation pump

A 2.5 gallon will give you hot water from the first second. You do not need a recirculation pump to expedite the process as hot water is already waiting for you. This will save the 10-12 second wait for hot water and a lot of water that would have been wasted during the wait.

Easy installation

This point is significant. How installation cost of tank fewer water heaters makes, the damage behind a water heater double is always a matter of discussion. If the installation is easy and doable without professional help than this cost is easily bypassed. Ecosmart ECO MINI 2.5-Gallon 120V Electric Mini-Tank Water Heater is easy to install. All you need is to merely valve it into the water line and install directly at the sink. You can also choose to install the heater in-line with a more substantial hot water source, like another storage tank heater or a tankless heater.

Enough for a small home

It is 2.5 GPM capacity water heater, with a central water heater you can choose this as additional support. If you have a low need, you can use it as a primary heater too. If you have a 1.5 GPM water saving showerhead, then this unit can support a shower head and a faucet/washing machine/dishwasher together. If you have a standard shower head with 2 GPM, still you can use a wash basin of 0.5 GPM. So yes it perfect for a small home of 1-2.

Pressure valve and recirculation pump replaced

What People Do Not Like

Lack of instruction on installation

It does not give out a manual on how to do the plant, making it a vigorous exercise for users. Also, it has a 1/2" connectors which are unusual and rare to find lines for.


Both are serious issues. Ecosmart group probably assumes a professional will do the work so they do not waste money on instruction guide but that isn’t going to be accepted by the buyers who are not interested in spending money on installation.

So visit a hardware store like- Lowe's Hardware and you can get a 1/2" female to 1/2" female Brass Pipe Coupling with and a 1/2" Male (both ends) Brass Pipe Hex Nipple. Then use Teflon tape seven wrapping to make the other end as thick as possible for the bigger size of standard hose. You need Teflon tape wrapping in the hose too for perfect leak free connection. Now screw down coupling tightly to the unit. Screw through the Nipple until tight on the Coupling. Attach the faucet connection, after fighting with bare hand use a wrench, voila no leak no loose connection. Still, you can use a PVC pipe to collect the leakage water and ran it into an aluminum roasting pan for keeping another place dry. If you do not have a plug where you want to install it, you need an electrician to do the job. Otherwise, plug and play.

Additional parts needed

Tough the package says it can be plugged into a 120V outlet, there is no plug provided. A lot of other components are required to be bought to install it.


Yes, you need some visit to home depot and spend few more bucks to buy the plug, Teflon tapes, 1/2" female Brass Pipe Coupling with and a 1/2" Male (both ends) Brass Pipe Hex Nipples for the installation. However, a built-in pressure valve, a point of use system of Ecosmart ECO MINI saves much of your expenses you had to make for a tankless heater without these features. Once it is installed, the trouble is worth taking.
