User Tips for Commercial Electric Tankless Water Heaters

• Regular Maintenance:

• Schedule routine maintenance checks to ensure optimal performance and longevity of the unit. This includes cleaning filters and flushing the system to remove mineral buildup.

• Monitor Water Quality:

• The quality of incoming water can affect the performance of the heater. Use water softeners if necessary to reduce scale buildup.

• Install a Pre-Filter:

• A pre-filter can help reduce sediment and debris entering the unit, prolonging its life and efficiency.

• Educate Staff:

• Train staff on proper usage and maintenance procedures to maximize the benefits of the tankless system.

• Consider Cascading Systems:

• For larger facilities, consider installing multiple units that can work together. This provides redundancy and ensures that hot water supply remains uninterrupted during peak demand times.
