Solar Hot Water

Solar Thermal Water Heating Systems use the sun's energy to heat water for use by homes, commercial buildings and swimming pools. While some solar collectors look like solar photovoltaic panels, they are quite different. Solar thermal panels do not generate electricity, but simply absorb sun's heat.

Installation, Warranty & Maintenance

How and Where They're Installed

Most solar water heating systems are roof-mounted. For best results, the roof should:

  • Receive direct sunlight between the hours of 10 AM and 4 PM year round;
  • Face South (within 15°);
  • Be relatively new and sturdy, with the shingles in good condition.

If the roof isn't appropriate for a solar water heater, the system may be ground-mounted on suitable unshaded land next to the building where the hot water will be used.

Warranty, Operation, and Maintenance

  • The average life expectancy of solar water heating systems is 20 years or more, much longer than standard gas or electric storage water heaters (Source: EnergyStar)
  • The system does require some moderate maintenance. Annual / periodic maintenance will ensure efficient operation.
  • 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;
    • 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.
