The purpose of the research is to find methods of improving the efficiency and productivity of a solar heater, reduce its cost and prolong its service life. The authors insulated the floor of the heater with type FRP-I foam plastic on a base of phenol-formaldehyde resin of the resol type. The experiment was conducted in parallel with two water heaters. The first had wood insulation, the second the FRP-I plastic foam. The technique of preparing the thermal insulation is given.
