Hard water can lead to heavy mineral buildup in tankless water heaters.

Frequently Asked Questions About Tankless Water Heater Maintenance in Myrtle Beach
The cost for tankless water heater maintenance in Myrtle Beach, SC typically ranges from $150 to $300, depending on the unit's age, condition and the extent of descaling required. This includes a full flush and inspection of critical components. More complex issues or additional repairs would be quoted separately.
Yes, electric models scale up on their heating elements and need flushing and filter cleaning. We also check high-amp wiring connections for any sign of overheating.
Neglecting maintenance can lead to several problems, including reduced heating efficiency, higher utility bills, decreased hot water output and eventually, costly breakdowns. Mineral buildup can severely restrict water flow and damage the heat exchanger, potentially leading to premature unit failure and expensive repairs or replacement.
Tankless water heater maintenance focuses primarily on descaling the heat exchanger and checking electronic components for efficiency. Hot water tank maintenance typically involves flushing sediment from the bottom of the tank, checking the anode rod for corrosion and inspecting the pressure relief valve. Both aim to prolong life but address different system specifics.
While some basic tasks like cleaning external filters might be possible for a homeowner, full maintenance, especially descaling the heat exchanger and inspecting gas lines, should be left to a licensed professional. Improper servicing can damage the unit, void warranties and create safety risks related to gas and carbon monoxide.
If you have isolation valves, a pump and the right solution, a handy homeowner can do it. A pro visit also checks gas pressure, venting, sensors and condensate, which a DIY flush skips.
Most tankless water heater manufacturers recommend annual maintenance to ensure good performance and extend the unit's lifespan. In areas with harder water, more frequent checks, perhaps every 6 to 9 months, might help to prevent excessive scale buildup.
Most visits take one to two hours, including the descaling cycle. Installing isolation valves on the same trip adds roughly an hour.
