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.
Because we dispatch from the St. Louis Metro area, a MGA Plumbing plumber can usually reach any address in Ballwin fast — including St. Louis and O'Fallon. For tankless water heater installation emergencies, that speed is the difference between a simple repair and major water damage.
