Which Computer Board Do I Need For My i12 Tankless Water Heater?
Updated over a week ago

The Eccotemp i12 Indoor 4.0 GPM Gas Powered Tankless Water Heater is quite the gem that is designed for small to medium hot water production where you need more than one hot water application at the same time. It offers a 35-40 degree Fahrenheit temperature rise when operating at a flow rate of 4 GPM and a 77 degree Fahrenheit temperature rise at 1.5 GPM. IT only pulls about 2 watts while idle and 1.076 Amps during operation.

If you run into an issue requiring you to get a new computer board for your i12 it is important that you first speak to our support team to determine that is indeed what you need. You can contact them at [email protected] or visit and live chat with them as well.

There are two different versions of the i12 that are currently in circulation, so naturally there are two different computer boards depending on the serial number on your water heater.

***You can locate your serial number on the right side of your water heater for this portion. You will need it to determine which computer board you need.***
