    Can you show the filters too? I am not sure where they are or how to clean them. Also what did you add to the water flush solution? Any descaling chemical or anything??

    He also took a while to tell you to run vinegar through it

    Good informative video! For a combi unit do you need to flush out both the domestic hot water and central heat exchangers? In other words do a one hour flush for each the domestic hot water and central heat? The central heat pipes are usually 1" versus the 3/4" for domestic hot water. So how is the central heat side flushed?

    Thanks for the feedback! From what I know you only flush the domestic side. The other side is a closed system

    Wondering why you didn't flush both the domestic hot water AND the space heating sides of the combi unit?

    Good question. I did once and it didn’t go so well…and then I read you’re not supposed to because it’s a closed loop system and by adding new water it adds oxygen to the existing water that is purged of oxygen and it will corrode the heat exchanger. Just what I read!

    Sounds like the heat exchanger for the heat side may need to be replaced but flushing certainly wouldn’t be a bad place to start. Never know 👍🏻

    Do you like the Navien Combi? I had one installed several year ago, and I also pay to have it flushed every fall, but I feel it’s a money pit.

    After I worked the kinks out with the error codes I was getting it’s been great! It’s easy to flush, I bet they charge crazy money to do so. I have a video on my page showing how!

    Other side is a closed loop system and new air via new cold water shouldn’t be introduced. Probably why there’s an air purge ;)
