[VAC] Re: [VAC} Radiant heating data

Home Power tends to post magazines on their web page. I don't know about
history. I didn't see the Oct/Nov issue in the book stores, probably
didn't visit a book store in that time period. I've made up for that
this month.

That 10 watt pump sounds like just the thing.

It takes a lot of water or stone to store heat from day through the
night. And it takes a lot of insulation to gather enough heat during the
day to have any to store for later use. With my 192 square foot
collector in the last 70s, and an old house, I found I had nothing to
store. An Airstream isn't insulated well enough to do significantly
better.
