Combi Boiler Repair in Sumgayit: Water Heating Problem Resolved

A resident of Sumgayit contacted ustamvar.az because the combi boiler was operating but was not heating the tap water sufficiently, and the hot water frequently turned cold. During the call, the operator collected information about the combi boiler's brand, model, system water pressure, when the problem first appeared, and whether the unit displayed any error codes. After reviewing the details, a qualified combi boiler repair technician was scheduled to visit the following day.

Upon arrival, the technician checked the system water pressure, flow sensor, three-way valve, plate heat exchanger, and electronic control board. The diagnosis revealed that limescale and sediment had accumulated inside the plate heat exchanger, preventing the water from reaching the required temperature. The heat exchanger was professionally cleaned using suitable products, the water circulation was checked, and the system was readjusted.

After the repair was completed, the combi boiler was tested in both hot water and heating modes. The technician confirmed that the tap water temperature remained stable, the radiators heated normally, and the system pressure remained at the required level. The safety sensors and overall performance of the unit were also checked.

The repair was completed in approximately two hours. The customer was advised to have the combi boiler serviced at least once a year, regularly check the system pressure, and arrange a professional inspection promptly if changes in the hot water temperature are noticed.
