Take a hot shower. Apricus water heating tubes provide all the hot water for the house, including the hot water for the radiant floor. The tubes absorb the sun’s heat in an insulating layer of air-evacuated glass. While the outside of the tubes are cool, the inside the tubes can exceed 300º F. The tubes eliminate the need for an electric or gas water heater.
