A water softener is highly recommended when installing a tankless heater. Please ask us about our free extended warranty package when purchasing a Professional Series water softener with a tankless water heater. All tankless water heaters are affected by hard water. This can be remedied by using a water softener or de-scaling unit on a maintenance program.

When a tankless water heater and water softener us simultaneously, we offer 5 years labor warranty on tankless repairs.
