Solar water heaters (SWH) have gained popularity in Vanuatu as a sustainable and cost-effective solution for water heating.

Given the country’s reliance on imported fossil fuels and the high cost of electricity, many households and businesses are turning to solar energy to meet their hot water needs.

This article explores the adoption, suppliers, manufacturers, pricing, and benefits of solar water heaters in Vanuatu.

Overview of Solar Water Heaters

Solar water heaters utilize solar thermal energy to heat water, reducing dependence on traditional electricity sources.

The main components of these systems include solar collectors, storage tanks, and circulation systems.

The two primary types of solar water heaters are:

• Active Solar Water Heaters: Use pumps to circulate water or heat-transfer fluids.
• Passive Solar Water Heaters: Operate without mechanical pumps, relying on natural convection.
