What is the warranty on a tankless water heater?
Since the average life span of a tankless is a20-25 years, you will want to find the longest warranty out there. Most manufactures run between 10-15 years on the heat exchanger. A.O. Smith has a 15 year warranty were as Rheem only has a 12 year warranty on the heat exchanger. In most cases the heat exchanger is the most expensive part to replace on a tankless unit. However, If you have hard water, then the warranty might be worthless.
