A unit for harnessing solar power for heating water at high pressure, in which the circuit is exposed to freezing, comprising: a heat exchanger made as a single piece for a hydraulic circuit, made up of parallel polymer pipes (1) connected at one end thereof to a main branch-off pipe (2, 3) and, at the other end thereof, to a main collector pipe (2, 3); a sealed box (4) for a whole number of units connected in series, having a profile of regular section (5), reinforced by brackets that can be inserted in In corners, with a translucent face (6), the other face having an insulated cover (7); the profile having a geometry suitable for connecting the box to a support structure; the profile having a geometry suitable for holding the insulating material (8) and the rubber seals on the inner part of the translucent face (9); the profile being such that complementary profiles (10) may be assembled thereon, by snap-fitting, and the complementary profiles have a housing for rubber seals (11) on the outer part of the translucent face (6); means for connecting a water supply pipe (12) to the main branch-off pipe(s) and means for connecting a discharge pipe (13), in the direction of water consumption, to the main collector pipe(s). Use of the unit with direct connection to a pressurized water heater located on the unit, for heating the water of the water heater by means of circulation by convection. Use of the unit with direct connection to a pressurized water heater, which is in an arbitrary position with respect to the unit, with circulation by a hydraulic pump.
