150 Litre Solar Geyser Evacuated Tube Conversion System

150 Litre Solar Geyser Conversion (150L) — The balanced retrofit solar geyser for small families

Our solar geyser conversions upgrade your current electric geyser with an efficient retrofit solar geyser collector and smart controls. The 150 Litre (150L) package adds an evacuated-tube manifold, a circulation pump and a Geyserwise Controller so your existing tank is heated primarily by the sun, while the element remains as backup for cloudy periods.

What’s included in this 150 Litre evacuated tube conversion

• Retrofit manifold + evacuated tubes sized for a 150 Litre load (150L) — high solar absorption with rapid heat transfer.
• Roof mounting frame and weather-rated fasteners for tiled/IBR roofs (confirmed at site survey).
• Hydraulic kit: valves, lagging/insulation, piping & standard fittings for a neat tie-in to your geyser.
• Geyserwise Controller & pump for temperature monitoring, circulation control and timed element backup.
• Professional installation with a PIRB-certified plumbing CoC on completion.

Why choose this retrofit solar geyser (150L)

• Lower electricity bills: solar heat does the heavy lifting; the element tops up only when needed.
• Keep your existing tank: a solar geyser conversion avoids the cost of a full replacement.
• Right size for 2–3 people: typical use ≈ 50 litres/person/day — the 150 Litre (150L) is the sweet spot for many homes.
• Evacuated tube efficiency: consistent performance in cool, windy or variable weather conditions.
• Neat, compliant install: professional workmanship and a PIRB CoC for peace of mind.

How a solar geyser conversion works

The evacuated tubes capture solar energy and heat water at the collector. A small pump circulates water between the collector and your existing geyser under Geyserwise control. The controller prioritises free solar heat and allows scheduled element boosting. Most households see a meaningful reduction in water-heating energy with a 150 Litre solar geyser conversion.

Installation areas, roofs & compliance

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