Tankless Controller

The controller quit working on our tankless water heater, and Supply House had the replacement part in stock. Ordered the controller after speaking to Supply House, they shipped it out that day and received in 2 days. I was able to install the controller, adjust the settings, and had hot water again. Would definitely order again from Supply House.

Control board for Rinnai

Our plumber installed the board for us and it took a small amount of time. He said easier to install than he thought. I have hot water again in my tankless on demand hot water heater.

No longer available from Rinnai

This circuit board is no longer offered from Rinnai and it is original OEM. If you need one on the shelf you better get it before there are not anymore available.

Perfect replacement for older Rinnai Continuum

Our Rinnai Continuum REU-V2532W (R85e) went out after 17 years of perfect service. I checked voltages and realized the control board was getting power, but there was no power on the remote control terminals. This took about 10 minutes to replace and the extension connectors are greatly appreciated as they were needed for the connectors on my unit. After giving it a few seconds to boot and go through its initialization, we had hot water again. Shipped quickly and fantastic service. Supplyhouse.com is awesome and has saved me a couple of times when our furnace and now hot water heater were down. Highly recommend!

2 day shipping . great product. easy to plug in. i did not have to call a plumber who would have had to make 2 trips and then call the company to have them explain how to install the board.

Good price, worked well

For those who like me wondered what the extra stuff on the side was, that is the surge protector.
