I would like to set up a clothes washer in a location that has only cold water. (It will be in a makeshift shed of some kind, with a hose and an extension cord.)
I could just wash everything in cold for a while, but I was thinking of getting a small, cheap propane hot water heater. These are designed to produce a relatively small flow, for a single fixture, like a shower. A washer uses a lot of water, but it should be fine if the flow is low - it will just take a while for the machine to fill up. Is this OK?
For example, Eccotemp L5, $120 on Amazon
