I have an idea for a water catchment system and would like some input about if there's anything like what I have in my mind. OR if it will even work!?
Here goes nothing.. The idea I have in my head is a 1000 gallon (or however big) above ground cistern on stilts made of steel. Ideally you would have it coming down into a cone shape with your pipes going into the house. You could have all that internal with a outer shell that would have an air buffer between the inner cistern and the outer shell. With that you would have a fire box below that would essentially give you on-demand warm water, and keep the water from freezing in cold temperatures. May not be boiling, but warm enough for a shower or cleaning dishes.
Is there something out there like this? What would everyone think about this idea of they mostly rely on rainwater?
Would love some thoughts!
