  • Acquiring the hot water heating unit

http://wiki.cs.earlham.edu/images/6/6e/Unit_retrieval.JPG

  • We hope to be able to reuse an older hot water heater that Charlie picked up when the previous owner was done with it.

http://wiki.cs.earlham.edu/images/4/44/Dirty_unit.JPG

  • It has been stored in the woods awaiting an occasion for retrieval and testing.

  • Ready to transport the hot water heater from The Ranch to The Farm.

http://wiki.cs.earlham.edu/images/b/bc/Dry_dock.JPG

  • Set up for minor solar hot water heater surgery.


http://wiki.cs.earlham.edu/images/0/08/Unit_interior.JPG

  • The inside appears to be well preserved!

First Day of Setup

  • To test the effectiveness of the solar hot water heater we set up a lab that will allow us to measure the effectiveness of the solar hot water heater in converting solar energy into a rise in water temperature. See the specifics for this lab and the schematic for it under Documents in Progress- Solar H2O

http://wiki.cs.earlham.edu/images/5/50/The_barrel.JPG

  • For this lab we will use this barrell to house the copper coils that will transfer the heat from the water running through the solar hot water heater to the water that would normally be used in the household.

Note: For the lab the heated water just stays in the barrell.

http://wiki.cs.earlham.edu/images/9/92/Kate_cuts_barrel.JPG

  • To put the copper coil inside we have to cut it open. (We would take more care to seal it back up if this wasn't our test run.)

http://wiki.cs.earlham.edu/images/f/f0/More_cutting_kate.JPG

  • Yup, we really cut 'er open.

http://wiki.cs.earlham.edu/images/a/a9/Making_copper_coil.JPG

  • Ehren carefully coils our soft copper tubing.

  • The solder sweats up between the tubing and the fitting.

  • Horrah! Both are successfully sweated!

http://wiki.cs.earlham.edu/images/b/b7/Unit_hose_connect.JPG

  • We used teflon pipe tape to seal our connector fittings. These connectors allow us to attach our hose to our hot water heater.

  • Colin and Kate work together to securely attach the hoses.

  • We build a temporary stand for our pv panel.

http://wiki.cs.earlham.edu/images/4/46/Under_the_panel.JPG

  • We discover that an ideal angle for our latitude this time of year is 20 degrees. We roughly build our stand at this angle.
