Tank to Tankless Conversions in Gardner, KS
Converting from a 40 or 50 gallon tank to tankless frees up floor space and ends standby heat loss in a garage or closet. The catch is that tankless units usually need a larger gas line, often three quarter inch or bigger, plus new venting. We evaluate your meter size and pipe run before quoting so there are no surprises mid-job. We also cap or reroute the old flue and seal the roof penetration if it is no longer used. Plan for a conversion to take a full day.

We prioritize safety. All gas connections and combustion air requirements meet Kansas and local codes, heading off potential hazards and maximizing efficiency.

Restaurants, salons and small offices often use multiple tankless units linked together on a rack system. When one or more units fail, we replace them and rebalance the cascade controls so they share the load.

We also set up a descaling schedule matched to your water usage.

A standard tankless water heater replacement, if you are upgrading from an existing tankless unit, usually takes 4 to 8 hours.

If your unit is over 15 to 20 years old and repairs are becoming common and costly, replacement is often the more economical choice.

If possible, clear a path to the installation site and keep pets or children away from the work area. We will handle draining the old unit and all other technical preparations.

This typically involves annual flushing to remove mineral buildup, checking the air filter, and inspecting gas and water connections.
