Improper installation can lead to serious gas leaks, carbon monoxide poisoning, water damage or electrical hazards. It is best to hire a licensed and experienced plumber like BKN Plumbing.
A standard tankless water heater replacement, if you are upgrading from an existing tankless unit, typically takes 4 to 8 hours.
