For the past few months we have had running hot water! The system is still in testing mode and I will have to reconfigure it for winter, but it has been nice to turn on the tap and have instant hot or cold water.
Right now the system consists of two 55 gallon drums that I fill with a hose, then drive up to the house. These two drums last about a month before needing to be refilled. Once at the house, I hook them up the the panel you see in the photo. There is a 12V SureFlo pump that turns on when the tap opens. From there the water either goes straight to the cold tap, or through an on-demand propane water heater. The water heater is an Ecotemp L5. After a few months of using it, I can barely feel a difference in the weight of the propane tank. Right now the sink drain just goes through the floor and drains onto the ground.
Before winter I hope to have a basement finished for the house (more on that later). When that happens, I am going to try to sink a drive-point well in the basement. See this site for information on what that is. This will also give me a spot to run all of my plumbing that will be easier to protect from freezing. I will also have to dig a small drainage field for the grey water.
