The invention adds liquid solar heating to conventional house construction without altering the plans. Sections of moulded polyester resin embedding pipes connect together to provide a continuous liquid pathway which is hidden from view, or conduits may be moulded in the polyester resin thereby eliminating the pipes. The sections are artistically styled, obviating the unsightly appearance of present day solar equipped homes. The arrangement is very inexpensive, yet durable, and not subject to glass panels and its attendant breakage or the use of expensive copper tubing. The entire roof is a collector and different parts of the roof are exposed to the direct sunlight at all times of the day. Longitudinal seams accommodating thermal expansion are provided between adjacent sections by a trough terminating one section and a trough covering extrusion terminating the adjacent section. Rain and snow water run down the trough and off of the roof.
