Homemade Solar Thermal Collector

Step 5Water Storage

Water Storage
Once the collector is completed, begin working on the storage. Drilling two, ý holes into the 5 gallon bucket is necessary. Similar to the collector, drill one hole toward the bottom. This will be where the cold water is taken from. About two thirds the way up the bucket, drill another whole. This will be the hot water return location.

Attach the 2 Pex fittings to the bucket. In order to get a tight seal, use an o-ring for each fitting. Also use thread seal tape to ensure secure attachments.

Once the fittings have been installed, use the remaining duct insulation to wrap the bucket (side, bottom, and top) to increase insulation and minimize heat loss.

Attach the nylon tubing to the barb fittings and the refrigerator backing ends. The diameter of the tubing created a tight connection to both ends.

You are almost ready to test.
