We had this unit installed to replace a previous piece of Navien garbage - a heatbox - which was only a few years old. The installation cost much more than expected, there was no meaningful warranty service (the technicians seemed overworked and stumped); Ray blamed our issues on our existing piping and we had to involve many others. my advice: stay away from that company and from Navien entirely and be careful about other tankless claims.
- Approximate cost of services:
- $6.00
