Why Choose Tankless Hot Water Heaters?
Tankless water heaters are an efficient and space-saving option for modern homes, but like any appliance, they can develop problems over time. Ignoring these issues can lead to complete system failure, increased energy bills, and unexpected cold showers.
Common signs that your tankless water heater needs repair include:
Fluctuating Water Temperatures
Sudden changes from hot to cold are a clear sign your system is struggling to maintain consistent output.
Low Water
Pressure
Often caused by mineral buildup or clogged filters, this reduces efficiency and performance.
System Error
Codes
These indicate internal malfunctions, ranging from ignition issues to sensor or venting problems.
Pilot Light
Issues
If the pilot light won’t stay lit, your unit won’t heat water, often pointing to a gas supply or ignition problem.
