Flummoxed By The Lack Of Hot Water? Possible Tankless Water Heater Repair Issues To Consider
The popularity of tankless water heaters continues to grow as more homeowners and building contractors learn about the advantages of these compact, efficient appliances.
But like their tank-style cousins, however, tankless water heaters are not infallible and can develop repair issues that will need to be addressed. If you own a home that has been outfitted with this type of water heater, here are some possible repair issues capable of stopping or interrupting the flow of hot water from your tankless water heater to your tap or showerhead.
Check for fuel and power issues
The first potential problem homeowners should consider is whether their tankless water heater is experiencing some type of fuel or power issue. In order to operate correctly, the appliance must have constant access to either gas or electricity, depending on the model. Homeowners with an electric tankless water heater who experience a lack of hot water should immediately examine the home's electrical panel to ensure that the breakers that govern the flow of electricity to the appliance have not been tripped.
Those that own tankless water heaters powered with natural gas or propane will want to check to see that a consistent supply of gas is available for the appliance to use. Propane models may not operate properly when the propane tank level drops too low and becomes unable to supply enough pressure to activate the water heater's ignition system.
Other potential repair issues that can cause a gas-powered tankless water heater to stop working include a dirty or failed ignition and an obstructed exhaust vent.
Check for pressure issues
Tankless water heaters require a minimum water pressure in order to activate their components and begin heating water. If a low-pressure situation exists, the tankless water heating system may fail to activate until sufficient pressure is restored. Plumbing leaks and pressure problems with the home's water supply, as well as mineral deposits inside the heater, can create or worsen water pressure issues.
If mineral buildup is found to be the problem, homeowners should consider having a filter or softening system installed to prevent further problems from occurring. Homeowners who live in hard water zones may need to have their tankless water heaters flushed periodically to prevent mineral buildup inside the components as that can cause them to stop working.
