Realized the large water heater I bought is mostly pointless, any recourse?
Came across a good deal on a open box/cosmetic damaged 11gal marine water heater. Thinking to myself it will be sweet to add to my overall water storage, along with the larger water heater tank acting as a big water "battery" thinking it will help me use less electrical power to heat once im at camp.
For whatever reason it came to me as a shower thought this morning that once my fresh tank is empty, my water heater becomes an inaccessible reservoir lol. Currently have a 10gal fresh, 13gal gray - which seems goofy, but i bought it this way, might switch them around if I can sanitize the gray tank.
Is there anyway to make the water heater supply accessible? My first thoughts are to have a second loop with some kind of inline pump that can handle hot water if such a thing exists, but I realize I would also need a vent somehow to allow for air to come in the tank, and some way to idiot proof it to make sure I turn off the electrical heat side once I get to this point.
Not the end of the world if I cant. Just annoying I could have got a 6 gallon for the price I got my damaged 11 gallon, and i probably could have fit the 6 without much modification, the 11 im going to have to redo my under sink arrangement.
