On average, how long can it take to convert from tank to tankless water heater.
On average, how long would it typically take to swap out a tankless (defective) with a tankless of same mfg and model?
Swap out, 3+ hours.
Tankless from tank, typically requires a new gas supply, electrical, mounting details. Need more details, but one day covers it.
The absolute best and only tankless brand we touch is Navien NPE A series
Thanks for that instant reply
Re the swap out, is there a special flush out and other procedures that warrant 4 hours other than the obvious cut off and disconnect of gas, elec, water in and out and vent?
