Codes point to specific faults such as ignition failure, flame loss, overheating or scale buildup. Each brand uses its own code list, and we use manufacturer guides to read them.
While some basic maintenance like filter cleaning can be done by homeowners, complex repairs involving gas lines, high voltage electricity or intricate internal components should always be left to a licensed professional. DIY attempts can be dangerous and void warranties.
Yes, regular maintenance, particularly annual descaling where water is hard, is important for tankless water heaters. It prevents mineral buildup, maintains efficiency and extends the lifespan of the unit, often preventing costly repairs.
Minor repairs usually do not require a permit. If the repair involves major changes to the gas or water lines, or if the unit itself is being replaced, a permit from the Oshkosh building department may be necessary. We handle all necessary permitting for you.
Typical signs include inconsistent hot water, a sudden loss of hot water, strange noises like banging or popping, a rotten egg smell or error codes displayed on the unit. Any of these symptoms call for a professional inspection.
Most repairs and descaling are done in one to three hours. If a part must be ordered, we usually return within a few business days.
Many tankless heat exchangers carry long warranties, while other parts usually have shorter coverage. Warranties may require proof of maintenance, which we record.
