Water Heater Installation FAQ


Should I replace my old water heater with a tankless unit?

Upgrading to a Navien tankless water heater provides an endless supply of hot water, eliminates standby energy loss, frees up floor space, and lasts up to 20 years (compared to 7-8 years for tank models). While initial installation costs are higher, lower monthly gas/electric bills and long unit lifespans offer significant long-term return on investment.


How long does a standard water heater installation take?

Replacing an existing water heater with a similar tank unit typically takes 2 to 4 hours. Converting from a tank water heater to a wall-mounted tankless unit usually takes 4 to 8 hours because it involves updating gas supply lines, installing direct-vent piping, and re-routing water connections.


Are water heater installations eligible for rebates or financing?

Yes. Qualifying high-efficiency tankless units and heat pump water heaters may qualify for federal 25C energy tax credits as well as local utility company rebates. Gudorf also offers flexible Synchrony financing options to make your new installation affordable with convenient monthly payments.
