Water heater

[wtmtnhiker]

Hi all,
Looking at the back of my Winnebago water heater there is the usuaal pex pipe, valves and fittings. There are also two hoses that look like automotive heater hoses. They go in to either side of what looks like a pipe welwded to the tank. Anyone can know what they are for? Thanks.
