Exterior Mount Tankless Units in Westfield, IN
Many homes have tankless heaters mounted on an exterior wall with no venting at all, since the unit exhausts directly outside. These units face sun, rain and temperature swings, which can break down plastic covers and wiring over time. Frozen pipes are a regular winter concern in Indiana, especially in crawlspaces, exterior walls, and unheated garages during hard cold snaps. When we replace them, we check the pipe cover, freeze protection settings and the electrical connection. We can add a protective pipe cover kit to shield the water and gas lines. Exterior models are often the simplest swap when the gas line is already sized correctly.

Frequently Asked Questions About Tankless Water Heater Replacement in Westfield
A like-for-like gas tankless replacement typically runs $2,800 to $4,500 installed, depending on the brand and venting. Converting from a tank to tankless often costs $4,000 to $6,500 because of gas line and venting upgrades. We give you a written quote before we start any work.
Yes, you can certainly replace a traditional tank water heater with a tankless unit. This is a common upgrade for homeowners looking for better energy efficiency and endless hot water. However, it often requires changes to gas lines, venting and possibly electrical wiring, making professional installation essential for safety and performance.
A standard tankless water heater replacement, if you are upgrading from an existing tankless unit, typically takes 4 to 8 hours. If you are converting from a traditional tank water heater, the process can take longer, possibly a full day, due to additional plumbing, gas or electrical changes required for proper installation and venting.
A standard tankless water heater replacement usually takes between 4 and 8 hours. This timeframe can vary based on whether we are replacing an existing tankless unit with a similar model or upgrading from a traditional tank water heater. A tank conversion may require more extensive changes to gas lines, electrical or venting.
Yes, tankless water heaters are generally more energy-efficient than traditional tank models. They only heat water on demand, eliminating the standby heat loss that comes with keeping a large tank of water hot. This can lead to real savings on your utility bills over time, particularly in homes with varying hot water usage.
We do not recommend it. Gas line sizing, venting clearances and combustion testing call for training, and improper installs can void the warranty or create carbon monoxide hazards.
Most manufacturers offer 10 to 15 years on the heat exchanger and about 5 years on parts for residential use. We add our own labor warranty and register the unit for you.
Well-maintained tankless units can last 15 to 20 years. In hard water areas without regular descaling, heat exchangers can fail much sooner. Annual flushing makes the largest difference.
