Why Annual Tankless Maintenance Matters
Most manufacturers require regular maintenance on tankless water heaters to keep the warranty valid. Over time, minerals and sediment build up inside the unit and make it work harder to heat your water.
An annual flush removes that buildup so your heater can deliver a continuous flow of hot water and run efficiently for years.
- Steadier hot water and fewer temperature swings
- A more efficient heater that works less to do the same job
- Less wear on internal parts and a longer system life
- Helps you keep up with manufacturer maintenance requirements
