Annual Service and Safety Inspection

Annual maintenance helps keep your tankless water heater operating at all times.

Why a Service and Safety Inspection Matters

Proper maintenance prevents the mineral buildup that causes most issues with tankless water heaters. Regular service and safety inspections keeps your system running efficiently and extends its lifespan. Manufacturers are requiring proof of regular maintenance when warranty claims are being processed.

Maintenance Frequency

Yearly vinegar flushing is recommended for tankless water heaters to prevent efficiency loss and damage to the heat exchanger from mineral buildup.

Stay Prepared

Regular Service and Safety Inspection maintenance prevents scale buildup that causes reduced water flow, higher energy bills, and costly repairs. Neglecting maintenance can void your warranty and cause breakdowns when you need hot water most.
