Tank to Tankless Conversions in Four Corners
Converting from a tank requires more than swapping units. A 40 gallon tank heater uses roughly 40,000 BTU, while a whole-home tankless unit may need up to 199,000 BTU, so the gas line often needs to be upsized. Venting changes from a metal flue to PVC or stainless, and the unit moves to a wall location. We remove and haul away your old tank and patch the old flue penetration.

The cost for tankless water heater installation in Four Corners can range from $3,000 to $6,000, depending on the unit type (gas or electric), brand, capacity and complexity of the installation, such as gas line upgrades or new venting.

While it may seem appealing, tankless water heater installation is complex and should only be performed by a licensed professional.

Long, cold winters and a dry climate are the main stresses on plumbing in Montana, with incoming water staying cold for much of the year.

Signs you might need a new water heater, tankless or otherwise, include a lack of hot water, rust-colored water, strange noises from the unit or frequent leaks. For tankless systems in particular, frequent error codes or a noticeable drop in hot water flow could point to a need for service or replacement.
