A Solar Heated Loo

Michael has developed this simple and elegant solar heated version of Arbor Loo that has many advantages as well as offering a little more comfort on those cold mornings.

The Arbor Loo provides a efficient and sustainable solution to the poop problem, saving thousands of gallons of water a year and providing useful tree planting compost.

I really like the nice simple space heating system.  It is a drain back system with the collector nicely integrated with the roof.  An IBC container is used for heat storage.  And, by leaving the insulation off the parts that face the "living space", the IBC also provides the heat distribution.

The only moving part is the pump -- no controller, no antifreeze, no heat distribution controls or pumps -- very simple.

I think that this kind of design could be applied to other simple space heating needs.

The loo under construction with the IBC container at the back (providing a heated backrest for the toilet seat).   I like the way the structure integrates the standard size door, collector, IBC and toilet seating area with no wasted space.

Full details on the build and performance of Michael's solar heated loo ...

Thanks very much to Michael for providing this material!
