Condensing Tankless Repair in Waterbury, CT
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate.

Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns.
