Navien’s comb-boiler (NCB) has had its share of criticism and praise alike but in my opinion there is one thing that gets me a little more than excited, the fact that nearly half the boiler must be removed to replace a part that is known to fail more than most other parts on the unit. As you’ll see in the video the PCB, main control panel, some internal [and external] piping and circ pump all must be fully removed in order to gain access to a failed 3-way diverter valve.
If you’re not sure what the valve does, you may not be alone but its really quite simple; when idle the valve is in position to supply flow from the heat exchanger’s supply outlet to either the heating system load (hot supply to system) outlet or to the flat plate heat exchanger to satisfy a call for domestic hot water. The problem is that its a piston type valve that can and will fail in a partially open position when there’s a call for DHW. The results are low flow to a potable water faucet at higher than desired temps [hence the reason I always spec and install a thermostatic mixing valve on the domestic side outlet]. The fix, while very time consuming, is relatively simple.
Hopefully this step-by-step video will familiarize the process for you if you’re faced with replacing the valve for the first time.

Navien’s combi-boiler is possibly the most common combi- in the US market but working on or replacing parts for the combi can be a real challenge. I’ve serviced and installed quite a few in the last 3-5 years and the flow sensor is definitely one part that seems to fail more than others. If you Read More

I’ve serviced and installed quite a few in the last 3-5 years and the flow sensor is definitely one part that seems to fail more than others. If you find yourself looking at this part replacement you may benefit from a couple tips I’ve shared in this video.

Sometimes its fun to step back and see the whole process from start to finish. Here’s a time lapse video of the prep and install for the radiant in-floor heating at the #duluthbuild project in Northern Minnesota.
I’ve been trying to document each step along the way for this project we are building for my little sister and brother-in-law and I’m starting with the over 7K sq ft of radiant. If you’d like to follow along you can search the hashtag #duluthbuild on either Facebook or Instagram, doing so will show you all the posts from the project.
