Frequently Asked Questions
How often does a tankless water heater need to be serviced in San Diego?
Due to San Diego’s hard water, tankless systems should be professionally flushed and descaled at least once a year to prevent mineral buildup inside the heat exchanger.
Can I replace my old tank water heater with a tankless model?
Yes! Converting from a traditional tank to a tankless system is very common. We evaluate your gas supply line and venting options to perform a seamless conversion.
Why is my tankless water heater fluctuating between hot and cold water?
This is often referred to as a “cold water sandwich” or is caused by low water flow, a clogged inlet filter, or scale buildup inside the heat exchanger. A professional service visit easily resolves this.
Are tankless water heaters more cost-effective in the long run?
Yes. While the initial installation cost is higher, tankless units last up to 20 years (compared to 8–12 years for tanks) and use up to 34% less energy, saving significant money over time.
