Your Source for Tankless Water Heater Installation in Harrisburg, SD
HWR Plumbing knows that hard water is the biggest threat to tankless units, since scale builds up inside the heat exchanger. Hard water is the norm across much of South Dakota, and many groundwater sources carry dissolved minerals like calcium, magnesium, sulfate and iron. We install service valves for easy flushing and recommend a scale inhibitor or softener to protect your warranty. You get efficient, endless hot water that keeps working.

Tank to Tankless Conversions in Harrisburg
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 dispose of your old tank and patch the old flue penetration.

We design the system to fit your plumbing layout and usage patterns.
