Why Is Tankless Water Heater Maintenance Important?
Many homeowners purchase a tankless water heater because of its efficiency and long lifespan.
What many don’t realize is that annual maintenance is required to keep it running properly.
Without regular flushing:
- Mineral scale builds up inside the heat exchanger
- Efficiency decreases
- Energy costs increase
- Hot water performance can suffer
- Components experience additional wear
- Manufacturer warranties may be affected
Regular maintenance helps protect your investment and maximize the life of your system.
