A vertical, post and panel fence substantially surrounds a swimming pool, at about ground level, the posts extending downwardly into sockets and the fence barring entry to animals or children while warming pool water circulated therethrough to ambient temperature and heating it to higher temperature by solar energy. The low cost panels are each formed of two edge-joined, corrugated sheets at right angles to each other. The vertical grooves form unobstructed, thin, vertical, water chambers fed at the bottom by the pool pump to flow upwardly at no more than 3 psi, and 60-70 gallons per hour for discharge from the top back to the pool. Flexible shower pipes, and hydraulic head pressure relief pipes normally extend upwardly from the fence, the latter to prevent bulge of the low pressure panels. The length of exposed fence is proportionate to pool capacity.
