Tankless Water Heater Installation is one of the most requested plumbing services in Greendale, Missouri — and MGA Plumbing's plumbers handle it every day. Fully stocked trucks mean most repairs are finished in one visit. Book online or call (888) 480-9811.
We also service existing tankless units: descaling, error codes, flow sensors and ignition problems.
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.
