100 Litre Solar Geyser Tube Conversion System

100 Litre Solar Geyser Conversion (100L) – Evacuated Tube Retrofit with Geyserwise, Installation & PIRB CoC

100 Litre Solar Geyser Conversion (100L) — Retrofit solar geyser solution for existing tanks

Our solar geyser conversions let you keep your existing electric geyser and add a high-efficiency retrofit solar geyser collector with evacuated tubes. The 100 Litre (100L) conversion pairs a robust manifold and tube set with a circulation pump and Geyserwise Controller, so your current geyser heats primarily from the sun while the element remains as backup. It’s the smart way to lower bills without replacing the whole cylinder.

What’s included in this 100 Litre evacuated tube conversion

• Retrofit manifold + evacuated tubes sized for a 100 Litre load (100L) — high absorption and rapid heat transfer.
• Roof mounting frame with weather-rated fasteners (tiled/IBR options on site survey).
• Hydraulic kit: valves, lagging/insulation, piping and standard fittings for a neat tie-in to your geyser.
• Geyserwise Controller & pump for temperature display, circulation management and timed element backup.
• Professional installation with PIRB-certified plumbing CoC on completion.

Why choose a retrofit solar geyser (100L)

• Lower electricity costs: solar energy does the heavy lifting; the element tops up only when needed.
• Keep your current geyser: a solar geyser conversion avoids the cost of a full replacement.
• Load-shedding resilience: hot water stored from daytime sun, with element backup when required.
• Efficient evacuated tubes: excellent performance in cool, windy or variable weather.
• Neat, compliant install: professional pipework, insulation and a PIRB plumbing CoC.

How a solar geyser conversion works

The retrofit solar geyser collector heats water via evacuated tubes. A small pump circulates water between the collector and your existing geyser under control of the Geyserwise unit. The controller prioritises free solar heat and can schedule the element for cloudy periods. Most homes see substantial savings on water-heating energy with a 100 Litre (100L) conversion.

Is 100 Litre (100L) the right size?

A 100 Litre solar geyser conversion typically suits 1–2 people in normal use (average hot-water use ≈ 50 litres/person/day). Larger households should consider a 150 Litre or 200 Litre retrofit solar geyser kit.

Installation areas, roofs & compliance

We install solar geyser conversions across Gauteng and Cape Town on tiled, IBR or corrugated roofs. During the site check we confirm mounting positions, pipe runs and controller location. A PIRB plumbing CoC is issued on handover.
