Frequently Asked Questions About Tankless Water Heater Repair
It typically costs $150 to $800, though the average tends to be around $600 to fix a tankless water heater. Tankless water heaters require periodic flushing of minerals and sediment from building up inside the unit, and when this maintenance is neglected, you will likely run into issues with your water heater that will need to be repaired by a professional plumber.
While tankless water heaters require significantly less repairs than storage tank water heaters, they can still encounter problems that will require a professional’s skillset to repair them when those issues do arise.
Your tankless water heater could stop working for a plethora of reasons; a plugged heat exchanger due to hard water, a blocked vent and air intake, or running too many hot water appliances at once. Tankless water heaters only heat water as needed, so running multiple appliances that require hot water can overwhelm your water heater and cause it to stop working. If your tankless water heater does stop working, call Steve's Plumbing & A/C Service - Big Island to have an expert help resolve the problem.
Common issues with tankless water heaters range from air supply and exhausts getting blocked (which can cause the device to shut down), the pilot light failing to ignite, sensors quitting at random, and more. It’s important to have one of our certified technicians at Steve's Plumbing & A/C Service - Big Island to repair your tankless water heater as trying to do it yourself could potentially void the warranty or cause further damage.
Tankless water heaters do rely on gaskets, seals, and other components that can wear out over time. Generally, an annual maintenance service will include an inspection of these components and give the ability to have them replaced when they start to show signs of wear or failure. However, if you do find water leaking from your system, don’t be alarmed. Simply call a repair technician to come out and take a look at the issue and our team will quickly identify the issue and fix it for you.
