they used them in the open road campers in 1967. i had one it works real good . this one had aradiator with flues under it when you turned the water on the gass came on and heated the water onley when you turned it on . this type water heaters wer used in Germaney for years .i have some shower heads that work on eletricty basekley the same way.water flow determoned the heat range .
