Specifications

Duraco solar water heater manufactured in Mauritius. Made from rust-proof SUS 316 inox and aluminium alloy — specifically suited to Mauritian climatic conditions. Registered with the DBM as an official supplier since 1995. Includes delivery, flat roof fixation and VAT. Plumbing and electrical works are excluded and must be carried out by a qualified tradesperson. Non-pressure / low pressure system suitable throughout Mauritius. Must be connected to an open circuit header tank — do NOT connect directly to mains pressure.

Working Principle — Thermosiphon (Non Pressure):
The solar collector uses open vacuum tubes to absorb solar energy and convert it into heat. Cold water heats up inside the tubes, its density decreases, and hot water rises into the storage tank. Denser cold water flows back down into the tubes. This thermosiphon process circulates continuously until the tank reaches the tube temperature. An assistant tank tops up water lost through evaporation.
