Pacific Solar PSH-16 — 16-Tube Solar Geyser Conversion Kit (SABS Approved) What it is: A high-efficiency, SABS-approved split system designed to convert your existing electric geyser into a cost-saving solar geyser using a 16-tube evacuated heat-pipe collector. Highlights 16 evacuated heat-pipes deliver stronger solar gain — ideal for medium-sized households SABS Approved: tested and certified for South African standards and reliability Split system design: collector sits on the roof, geyser stays in place (no tank on the roof) Smart temperature control with pump & controller ensures maximum solar efficiency Durable & weatherproof: anodised aluminum frame, copper heat pipes, high-transmittance borosilicate glass tubes Safe operation: integrates with pressure relief valves, non-return valves, and mixing valves What’s in the box PSH-16 Collector Assembly (manifold + 16 evacuated tubes, SABS-certified) Universal roof mounting brackets and hardware Sensor pocket in manifold for controller probe Installation guide/manual Optional Add-Ons (for complete retrofit) Pump & Differential Controller set (with tank + collector probes) Pre-insulated solar piping kit with isolation valves and non-return valve Tempering valve to ensure safe outlet water temperatures Compatibility & Sizing Suited for 150 L – 200 L geysers (2–4 person households) Works with standard horizontal and vertical electric geysers Compatible with all leading solar controllers and circulation pumps How it works The 16 evacuated tubes heat the manifold with solar energy. The controller measures collector vs. geyser temperatures. When there’s sufficient heat, the pump circulates water to the geyser, charging the tank. The electric element remains as a backup for cloudy days. Benefits 50–80% reduction in electric hot water bills SABS Approved for guaranteed performance and safety compliance Stronger solar gain than the 12-tube, making it ideal for families or higher hot-water demand Low-maintenance with replaceable individual tubes
