How To Install An EcoSmart Electric Tankless Water Heater Guide for 2018

5 kW to 36 kW and we will be showing you the installation of an 18 kW, ECO 18. In order to complete this installation, you may need the tools listed on screen. Before we begin, I would just like to remind you that sizing is very important when choosing an electric tankless water heater. Make sure your unit can provide the output you require before you begin your installation. In most cases, when installing an electric tankless water heater, you will be mounting the unit on the wall first.

Once that has been completed, you will need to connect your water source to the inlet side of the unit. You will then connect the pipe to the outlet fitting of the ECO 18 unit to provide hot water to the rest of the your house. Before moving on to electrical, you will need to make sure that all the plumbing connections were made correctly and then turn on all the fixtures in your home to purge the air from the water lines. You can now move on to the electrical installation. You must use the appropriate wiring for your specific unit.

For the ECO 18, you must have two sets of 8 AWG wire. You will also need a ground wire. First, connect the wires to your unit and then connect the other side of your wire to the circuit breaker. An ECO 18 requires two 40 amp double pole breakers. Make sure that all of the wires are connected properly before turning on power at your breaker panel.
