Installed this unit as part of a full renovation in March of 2019. Installation was done by a licensed plumber since the city required as much to get a gas meter. Unit worked great until yesterday when it just stopped turning on. I went to the Takagi website, pulled their troubleshooting manual and went through the steps. It seemed the control board was blown.
Foolishly, I made an appointment with one of the local service technicians listed on the Takagi website, thinking they would be able to replace the part. The technician that came out futzed around for about 30 minutes before telling me, "yep, control board is gone", charging me $75, and then leaving. Don't you guys have parts or can order the part? "Nope, you'll have to call Takagi."
I was more than unhappy to say the least. I called up Takagi, got a rep on the line in about 30 seconds and he walked me through some additional diagnostics the plumber that just left had neglected. After about ten minutes and a lot of probing with a volt meter he said he was going to overnight me a new control board and fans (just in case). While he was setting up my order it turned out they did not have the boards in stock. He gave me a replacement code and told me to go to any local distributor and they'd just give me a whole new unit.
2 hours later I have hot water again. Takagi support is best I've ever experienced with a major appliance. My local plumbers certified to service their goods, not so great.
As others have said, the unit does what it's supposed to. This one was good for two simultaneous showers or running a shower and the clothes washer or dishwasher. The cost savings in gas will pay for itself in about 4 years and the never-run-out hot water can't be beat.
