Solar Space Heating

Solar Thermal Space Heating Systems capture the sun's energy to supplement the existing heating system for a home or commercial building. The heating system intensifies the sun's power to heat water or air that is then used to heat the building. While some solar collectors look like solar photovoltaic panels, they are quite different. Solar thermal panels do no generate electricity, but simply absorb the sun's heat.

Installation, Warranty & Maintenance

  • How and Where They're Installed

    Most solar space heating systems are installed on the roof or on the ground adjacent to the building. For best results, solar collectors should be installed such that they:
    • Receive direct sunlight between the hours of 9 a.m. and 3 p.m. year-round; and
    • Face south (though they can be oriented up to 30% toward the southeast or southwest).
    Solar thermal systems are more forgiving than solar photovoltaic (PV) systems.  Solar PV panels need to be installed facing due south and are very sensitive to shading.
  • Warranty, Operation, and Maintenance

    • Solar Thermal system requires moderate annual/periodic maintenance to ensure efficient operation. Maintenance is generally provided by the installer and / or the manufacturer.
      • Periodic visual inspection may be necessary to properly maintain your solar system.
      • How well an active solar energy system performs depends on effective siting, system design, and installation, and the quality and durability of the components. The collectors and controls now manufactured are of high quality. The biggest factor now is finding an experienced contractor who can properly design and install the system.
      • A qualified contractor can conduct annual maintenance inspections, and check the following to make sure:
        • Collector is clean and not shaded;
        • Collector is sound, sealing and glazing are not cracked or yellowing;
        • Fasteners connecting collector to roof are sound;
        • Piping and wiring are well-connected, well-insulated, and without damage;
        • Roof penetrations are well-sealed;
        • Pressure relief valve is not stuck completely open or closed;
        • Pumps (in active systems) activate when the sun is shining; and
        • Pipes are free of mineral build-up.
      • If you live in an area with hard water, you may need to add de-scaling agents to the water every few years. For example, you can run a vinegar solution through the collector or hot water loop every three to five years.
      • Most solar thermal heaters are automatically covered under your homeowner's insurance policy. However, damage from freezing is generally not. Contact your insurance provider to find out what its policy is. Even if your provider will cover your system, it is best to inform them in writing that you own a new system.
