[Sparky!]

I'm in the process of designing a heat storage system for our home. One of my design criteria is the be able to buffer 3 days of no sun on the coldest days. I've calculated that 2 million btus of storage to be my target capacity.

I'm planning on using water and paraffin wax and a large tank. I've collected 3000 lbs. of wax so far but still need to find its melting temperature and design around that.

I'm in the process of sourcing a 2000 gallon stainless steel tank for the project.

Is this of interest to the group?

Thanks
