The house was built in 1954, I’m sure this is original. I’ve never seen one before, and am not sure how it works, being the burner is totally separate from the tank. Looks like a 1 1/4 pipe connects them. Maybe it’s the original “instant water heater”?
Not sure I should call out the cast fitting that supplies the hot water and the TPRV connection.
Seller was present, a 93 old lady. She was weed eating this morning when I got there, and was getting ready to mow the steep front yard with her new electric lawnmower. She said she just didn’t have strength to pull start the gas one anymore! :shock:
