I must respectfully disagree with fourth year.
If you buy a top brand tankless water heater you won’t have a problem getting parts years later.
Look at gas models Bosch (Aquastar) and Myson or for electric nothing beats Eemax brand. All three have been made for MANY years. All three are reputable companies and won’t go out of business.
Thankless heaters do cost more initially, and they are more complicated (and therefor do need service more often than a regular water heater).
In the U.S. you can buy all three online from PlumbingStore.com
They do save a significant amount of energy.
