Tankless Water Heaters and Boilers in Evansville, IN

Tankless water heater installation is the job when the house needs a new on-demand unit against EWSU's 138 ppm hardness, a conversion from a storage tank, or a replacement after the heat exchanger is done — not when a flush, sensor, or igniter fix is the whole problem tankless water heater repair can settle.

Gas and electric connections that go with the equipment are part of the install path on this page, and Indiana's fuel-fired placement ban still applies before the cabinet lands. Indiana bars fuel-fired appliances from sleeping rooms, bathrooms, toilet rooms, and storage closets unless they are direct-vent and take combustion air from outdoors — that placement rule matters before a fuel-fired tankless lands in a tight closet. Evansville hardness averages 138 ppm (8.1 gr/gal) in EWSU's 2025 CCR, so scale management and inlet filtration are part of keeping a new tankless alive here; a whole-home water softener is a separate Water Line job when hardness is the supply-side problem.

What changes the scope of a tankless water heater installation visit is fuel type, venting or electrical capacity, Indiana direct-vent rules for fuel-fired closets, and whether a storage tank comes out the same day — not a single price on this page. A free quote settles the number for your house before anyone starts; there's no trip or diagnostic fee.

Tankless water heater repair is the job when the cabinet and heat exchanger still make sense under Evansville's USGS hard-band water and the fault is an error code, igniter, flame sensor, scale-related flow cutback, or condensate / inlet filter issue — not when the exchanger is cracked or the unit is past a sound rebuild.

Descaling and service belong here when Evansville's hard-water average (138 ppm / 8.1 gr/gal per EWSU 2025) has slowed the unit and a flush restores flow. USGS notes hard water can cause mineral buildup in water heaters; that reading supports why tankless units need periodic service here, not a promise that every error code is only scale. If the unit is out of service and the house has no backup, say so when you call so we prioritize the no-hot-water path.

A leaking residential storage tank is water heater replacement, not tankless repair. A commercial storage tank is commercial water heater install and repair — even when USGS-noted scale helped kill it.

Boiler repair is the job when a residential boiler will not heat, a circulator is dead, the loop is leaking at a known joint, or the burner / controls need service — not when a domestic storage water heater or a commercial tank is the failed plant, and not when Indiana bars a fuel-fired appliance from a sleeping room or bathroom closet without direct-vent outdoor air.

Boiler replacement and new boiler installs on existing hydronic systems sit on this same composite GBP page when the boiler half of Tankless Water Heaters and Boilers is the work. Circulator pumps, zone issues, and no-heat calls stay here; we do not invent a separate commercial boiler offering on this page. If the call is really a domestic tank with no hot water at the fixtures, use the residential tank page instead of forcing a boiler label.

We're open 24/7 for tankless water heater installation, tankless water heater repair, and boiler repair across Evansville and the Tri-State. Call (812) 677-8484 when you're ready.
