MGA Plumbing is the St. Paul plumbing company to call for tankless water heater installation. Our local plumbers are available 24/7, arrive on time and fix the problem right the first time. Transparent flat-rate pricing before any work begins.
Tankless water heaters heat water on demand — endless hot water, up to 30% lower energy use and a footprint the size of a suitcase. Proper sizing for Missouri's cold groundwater and correct gas and venting are critical, and that's where experience counts.
We also service existing tankless units: descaling, error codes, flow sensors and ignition problems.
Homes in St. Paul range from older houses with original galvanized and cast iron plumbing to new construction with PEX — and each needs a different approach to tankless water heater installation. Our St. Paul plumbers know the local housing stock, soil conditions and water quality, so you get a lasting fix instead of a temporary patch.
