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 Westfield
We plan every Westfield tankless install around your home’s gas supply, venting route and hot-water demand. A gas tankless unit can burn several times as much gas as a 50-gallon tank, so we verify the meter and line size first. High-efficiency units usually vent through PVC and need a condensate drain, and we size the unit for the fixtures you run at once.
Our standard installed price is $4,499, and any gas-line, venting or electrical work beyond the standard scope is quoted and approved before we start. See all installed prices.
Is a tankless water heater worth it in Westfield?
With water this hard, tankless is worth it if you’ll keep up with yearly descaling or add a water softener. Do that and you get endless hot water, more floor space and a 15-year manufacturer’s limited warranty on the units we install.
If upfront cost is the priority, a new tank heater costs less to install. Compare Westfield water heater replacement.

Westfield’s very hard water and tankless units
Citizens Energy Group’s 2025 water quality data for its Westfield system shows average hardness of about 360 ppm, around 22 grains per gallon, with samples ranging from about 270 to 470 ppm. Homes on Citizens’ separate Westfield–South Madison system have their own figures.
At that level, scale builds quickly on a tankless heat exchanger and is a common cause of error codes, overheating and shutdowns. Plan on at least a yearly descale. Our Tankless Carefree Plan covers it for $99 a year, and ScaleShot is our citric-acid descaler for do-it-yourself maintenance.
