Introduction about Mini Electric Tankless Hot Water Heater

Best Mini Electric Tankless Hot Water Heater Buying Guide

Mini electric tankless hot water heater refers to a small water heater installed in the kitchen for washing dishes, foods and other purposes. According to this picture above, we have learned that it’s belong to one of the three types of water heaters--electric water heater, which uses electricity as an energy source for heating.

Compared to the common water heater, however, mini electric tankless hot water heaters cannot be used for bathing, since its power, temperature and flow rate cannot meet the needs to bath.

Considerations before Purchase

1. Installation Location

It is necessary to determine where you are going to install this machine, and purchase according to your actual needs. There are two types of mini electric tankless hot water heaters: upper water outlet and lower water outlet. You could choose the first one if you prefer to put this item below the faucet, or you would better choose the second one.
Note: If it is placed in a cabinet, you have to consider the connection method of pipes in advance and make sure enough space is reserved in the cabinet.

2. Power

The higher power of the water heater, the less time we will wait to get the hot water. But blindly choosing high power may generate some unnecessary security issues. Therefore, when choosing the power of mini electric tankless hot water heater, it is better for us to consider the home electric meter and the size of the power cord. If the electric meter has a large capacity and the power cord is thicker, you can choose to buy this item with a high power. Generally speaking, there is no problem for most homes to install this machine with the power of 3500 w, which can offer the hot water within 3 seconds.

3. Warranty

It’s better for you to find a water heater with a longer warranty available. As we all know, there are some minerals in water, such as calcium and magnesium, which could produce mineral scale.

As the scale builds inside the tankless appliance, the heater is required to work harder than necessary. Eventually, this could lower the energy efficiency, and shortens the service life, or lead to the system overheating and shutting down.
