Your Tankless Water Heater was a BIG investment. Endless hot water, space saving and gas saving are a few of the reasons more and more households are opting for tankless water heaters. But did you know that San Diego County’s water quality will have detrimental effects on the performance and lifespan of your tankless water heater?

What can be done to prevent damage to your tankless water heater? Two main things are recommended:

1. Perform a descale of the heat exchanger in your tankless water heater at the least annually although semiannually will have more beneficial results.

2. Pretreat your water: Due to the water hardness of our area most manufacturers recommend pretreating, or softening your water before it enters your tankless water heater. Operating the tankless water heater in conditions outside what is required by the manufacturer can even void some warranties.
