Water heater age

[Steven Delaney]

Is anyone familiar with determing the age of a John Wood water heater Model JW540SNA ser# 9701254027. All I could determine from their website is that it is out of warranty.

Thanks Wayne. Is that the standard formula for john wood water heaters- first 4 digits of ser #?

Yes, sometimes it is switched though , use AO Smith hot water heater code
