Gordon's "$1K" Solar Water Heating -- From New Zealand

Gordon has provided details on how he built his version of the "$1K" Solar Water Heating system.  These systems are high quality, high solar fraction, all climate solar water heating systems that you can build for about $1000 in material costs.

Gordon's system adapts the design to his situation, his changes include:
- A well made, high tilt angle roof mount for the collectors.
- An all copper, single pass heat exchanger that pre-heats water before it gets to his existing hot water heater


Full details and build instructions on Gordon's Solar Water Heating System...

  1. Great work Gordon,
    I am just finishing up an MTD type system and am particularly interested in how you built your differential controller. I have a Basic Stamp that I am trying to learn how to operate, and I have a bunch of DS18S20s and a PIC chip. Would you care to share a schematic?

  2. Thanks Bill,
    I am just tidying up the controller, and will be sending Gary another pdf with all the details as soon as I can.
