I printed out your response to my post about the 2 1/2 minute time for the hot water to reach the kitchen sink faucet for my husband to read. (he's not computer literate) When we finally got the plumber to get here to check out the situation, after 2 missed appointments, and at first he still seemed to think that 2 1/2 minutes was fine. Until my husband decided to show him the print out of what you 'd said...lol
Then all of a sudden he agreed that 2 1/2 minutes WAS too long. I said I was glad he believed me. He said he'd always believed me, he just didn't know I'd timed it...HUH? That means you didn't believe me.
So he came back 3 days later when we were out of town (we told him we wouldn't be home but he forgot) to work on it. We got home late last night and found the water pressure had been cranked WAY up from our well pump. The noise is still there, of course he says the noise is normal anyway, and the hot water take a little over 2 minutes instead of 2 1/2.
Also waiting for us was our bill from him. The amount he charged us or the water heater was pretty close to what he quoted us, but ht had charged us 22 hours labor (2 young guys at 11 hours each) for the installation. I don't have a clue if the guys were licensed plumbers or not, but I'd be surprised if they were. They were full of uncertainty throughout the install, and made 10 trips up and down the stairs every hour. They even had to drive back to their shop (23 miles away) to get different parts because the vent the boss had sent with them wouldn't work. Then they left after 10 hours and had mistakenly shut the system off when they left and had to turn around and drive back to our house. We were charged for both young guys time to drive back and forth both times to correct their screw ups.
They didn't have to repipe our house. This was the first Navian they had ever installed and the boss wasn't there, but he had never installed one either.
The boss had quoted us 6 hours labor each for 2 guys. The charge was $70 per guy per hour.
How many hours is "normal" to install a Navian tankless heater, because I think we got screwed AND it's still not right
