This presentation was written by Harvey Bowers of the Alaska Center for Appropriate Technology (ACAT). It provides information on solar thermal water heating in cold climates and uses a case study and examples from installations in Alaska to demonstrate how solar thermal can be effective in similar settings.
Solar thermal heating, as demonstrated by the residence in question, works best in climates like Alaska’s when utilizing passive design and closed loop systems, as keeping solar fraction high is challenging during the winter.
Tax credits are available in Alaska for installation costs and the materials associated with passive solar thermal heating.
