FROM TANK TO TANKLESS
Real photos from a tank-to-tankless conversion we completed in Westfield, Indiana. We removed a 50-gallon power vent water heater and installed a wall-mounted Navien NPE-240A2 tankless water heater, freeing up floor space.

Tankless water heater installation in Zionsville
If your home runs two showers, the dishwasher and laundry at once, the unit has to be sized for that peak and for how cold the incoming water gets in winter. Bigger homes sometimes need a higher-capacity unit or two units. We also confirm your gas line and meter can carry the load and plan the venting before we quote.
Our standard tankless installed price is $4,499. Gas-line, venting or electrical work beyond the standard scope is quoted and approved before we start. See all installed prices.
Is tankless worth it for your Zionsville home?
It usually is if you keep running out of hot water, want the utility-room space back, or plan to stay long enough to get the longer service life. Every tankless unit we install carries a 15-year manufacturer’s limited warranty.

Hard water and tankless units in Zionsville
Central Indiana water runs hard. Citizens Energy Group’s 2025 water quality report estimates typical hardness across the region at about 200 to 425 ppm, or 12 to 25 grains per gallon. Your utility’s annual report, or a water test if you’re on a private well, shows where your home falls.
Those minerals build up as scale on a tankless heat exchanger and can lead to error codes, temperature swings and shutdowns. A yearly descale keeps most units running right, and our Tankless Carefree Plan covers it for $99 a year. If you descale your own unit, ScaleShot is our citric-acid descaler.
