  1. Intensive investigation reveals: ....Ethiopia is both cheap and sleazy....the near perfect combination.

    Get there before the mass of other people discover all the fun to be had and ruin it for all the fun seeking budget travelers.

    sshhhh don't tell everyone.
  2. Your solution is a open vented thermosyphon system with a heat exchanger. It takes time and effort to construct but can be done really cheaply. Be very very careful with a homemade circulating solar system. Without the appropriate pressure, temperature relief and safety valves you will basically create a bomb. You will also get water so hot it will most likely damage your plumbing and tapware or will scald you unless you install a high

    You can make a pressure less solar hot water circulation system. Then there is no risk for over pressure.

    I made one ten years ago, and is still working without any problem.

    i didnt say you can't make a pressureless system,thats is how i explained my system. Is your system completely closed? If so you must have some form of relief for thermal expansion. Can you explain how you have set it up?

Be very very careful with a homemade circulating solar system. Without the appropriate pressure, temperature relief and safety valves you will basically create a bomb. You will also get water so hot it will most likely damage your plumbing and tapware or will scald you unless you install a high performance tempering valve which are unavailable in Thailand. Using this system will not create any pressure or flow restrictions and you will not need a huge supply pipe for your bath. Now as for your boosting system. This is the expensive side but it works.. you need to fit a continuous flow LPG hot water service as a booster for your heat exchanger with a thermostatically controlled pump to increase the temperature of your heat exchanger when the sun is not shining.
