Free Hot Water Offers A Solar Hot Water System
for the White House
Free Hot Water is proud to be part of a grass roots initiative to put solar panels back on the White House. A solar hot water system was briefly installed on the White House roof in the 1970’s, but the system was quietly removed in the 1980’s. In 2003, the National Parks Service installed a small solar electric system and a solar thermal system on its White House maintenance shed, which are still functioning today. Free Hot Water is donating this solar thermal system to the White House because we believe that solar should be returned to the White House roof as a public symbol of America’s new dedication to clean, renewable energy.
The White House System comes with the following:
Engineering & Design
3 - FHW-FC7275 collectors
1 – 110 gallon storage tank w/heat exchanger
1 - 3–Collector Mounting Kit
1 - Closed Loop Connection Kit
