200L Evacuated Tube Solar Geyser Conversion System

This 200L evacuated tube solar geyser conversion system is designed to upgrade your existing 200L electric geyser into a high-performance solar hot-water system. Using advanced evacuated tube heat-pipe technology, the system absorbs sunlight far more efficiently than flat-plate collectors and maintains high performance even in colder or cloudy conditions. This split-system design keeps your current geyser in place while the new solar collector and pump circulate solar-heated water for maximum efficiency.

High Heat Absorption – Faster Heating, Lower Costs

Evacuated tubes use a double-glass vacuum design with an internal copper heat pipe, allowing them to absorb and retain solar heat far more effectively. The system heats rapidly during sunny periods and continues to deliver exceptional performance during winter and early mornings.

Works With Your Existing Geyser

No cylinder replacement is needed — the conversion system connects directly to your current 200L geyser.
Your existing backup element and timer continue functioning normally for cloudy days, ensuring you always have hot water.

12V Solar Circulation Pump

A reliable 12V pump continuously circulates water through the collector system, ensuring stable heating throughout the day without relying on mains power.

Built for South African Conditions

The system is fully SABS-approved, hail-resistant, and suitable for frost-prone regions. Individual tubes can be replaced if damaged — no need to replace the entire collector.

Low Maintenance, Long Service Life

Maintenance requirements depend on water quality:

• Municipal water: optional anode replacement once per year.

• Borehole/wellpoint water: mandatory anode replacement every 6 months.

The anode is inexpensive and protects the internal tank from corrosion, extending system lifespan.

Why Choose a 200L Evacuated Tube Conversion?

A 200L system is ideal for medium-to-large households needing dependable daily hot water without high electricity costs. With solar-assisted heating, users typically save 30–50% on monthly electricity consumption.
