100L Apollo High-Pressure Thermosyphon Solar Geyser – Complete Installed System

The 100L Apollo high-pressure thermosyphon solar geyser is a compact complete solar hot water system for smaller households, flats, cottages, staff rooms, garden units and properties with moderate daily hot water demand. It is designed for customers who want a practical solar water heating solution without installing a larger system than the property actually needs.

This system is generally suitable for approximately 1 to 2 people, depending on shower habits, kitchen use, water-saving habits and backup heating settings. It can work well where hot water demand is predictable and where the current household does not require a large storage tank.

The Apollo thermosyphon design uses solar energy to heat water during the day. As the solar collector warms the water, natural circulation moves heated water into the storage tank and cooler water toward the collector. This allows the system to operate during normal solar heating without relying on a circulation pump.

Compact Solar Hot Water for Smaller Properties

The 100L Apollo high-pressure thermosyphon solar geyser is a good fit for smaller properties where hot water demand is moderate. It can suit single-person homes, couples, flats, staff accommodation, garden cottages, granny flats and compact rental units.

A smaller system can be a practical choice when the property does not need the larger storage capacity of a 150L, 200L or 300L geyser. It can reduce unnecessary oversizing while still giving the customer solar-assisted hot water and electric backup support.

The correct size depends on daily use. Short showers, limited bath use and controlled kitchen demand can make a 100L system very suitable. However, if multiple people shower close together, if baths are used often, or if the geyser regularly runs out of hot water, a larger option may be more appropriate.

Customers who need more capacity can compare this option with a 150L high-pressure solar geyser for small to medium households.

Complete Apollo Thermosyphon Solar Geyser System

This is a complete installed Apollo solar geyser system, not only a loose geyser tank. The system includes the 100L Apollo high-pressure solar geyser, solar collector, roof mounting frame, valves, pipework, fittings, insulation where required and the correct installation components.

The tank stores the heated water, while the collector gathers energy from the sun. The frame supports the system on the roof, and the plumbing components help manage pressure, flow direction, expansion and safe operation.

Because this is a high-pressure solar geyser, the installation must be handled correctly. The system connects to the property’s pressurised hot water plumbing, so pressure control, safety valves, mounting, pipe routing and insulation must all be planned properly.

How Thermosyphon Circulation Works

A thermosyphon system uses the natural movement of hot water. When the sun heats the water in the collector, the hotter water rises into the storage tank. Cooler water moves down toward the collector to be heated. This creates a natural circulation cycle while there is enough sunlight and temperature difference.

This design is simple and practical because normal solar circulation does not require a pump. Fewer moving parts during solar heating can make the system easier to manage when installed correctly.

The performance of the system depends on available sunlight, collector position, roof angle, shade, weather, pipe insulation and water usage habits. A good installation helps the system make better use of the sun during the day.

High-Pressure Hot Water for Daily Comfort

The 100L Apollo system is designed for high-pressure hot water use. This means it can suit properties with normal pressurised plumbing, mixer taps, showers and standard bathroom or kitchen fixtures.

Even though the storage capacity is compact, the system still needs proper plumbing protection because it operates as part of a pressurised hot water installation. Correct valve placement and pressure control are important for safe operation.

When installed correctly and matched to the right household size, a 100L high-pressure solar geyser can provide comfortable hot water for everyday use while helping reduce electricity usage.

Helps Reduce Electricity Usage

The main benefit of the 100L Apollo high-pressure thermosyphon solar geyser is that it uses solar energy to heat water during the day. This can reduce how often the electric element needs to heat the water.

In smaller homes, a geyser can still use unnecessary electricity if the element is left on for long periods. Solar heating helps reduce that reliance by using sunlight as the main heating source when conditions are suitable.

The amount of electricity saving depends on weather, roof position, shade, insulation, usage habits and controller settings. The system works best when solar heating is allowed to do most of the daytime work and electric backup is used only when needed.

Electric Backup Heating When Needed

The 100L Apollo solar geyser can include electric backup heating so the property still has hot water support during cloudy weather, winter periods, early mornings, evenings or heavier use.

This backup support is important because hot water is not always needed only when the sun is strongest. Many customers need hot water early in the morning or after sunset. Electric backup makes the system practical for normal daily routines.

The goal is to reduce unnecessary element use, not to remove backup heating completely. With correct settings, the system can use solar heating during the day and backup heating only when the stored water needs a boost.

Geyserwise Controller Option

A Geyserwise controller can be included with the 100L Apollo high-pressure thermosyphon solar geyser. The controller allows the customer to monitor the water temperature and control timed electric backup heating.

This is useful because the customer can see whether the solar collector has already heated the water enough. If the water is hot, the element does not need to switch on unnecessarily.

Timed backup heating can also be set around the customer’s normal routine, such as before morning showers or evening use. This helps make the system more convenient while keeping electricity usage better controlled.

Roof Mounting and Collector Position

The 100L Apollo thermosyphon solar geyser must be installed in a suitable roof position where the collector can receive good sunlight. The installer should consider roof direction, roof pitch, available space, roof covering, shade and frame support.

Shade from trees, walls, chimneys, parapets or nearby buildings can reduce the system’s heating performance. A good mounting position helps the collector receive stronger sunlight for more of the day.

The roof frame must be secured correctly and the installation must be neat. Whether the property has a tiled roof, IBR roof, corrugated roof or another suitable roof type, the mounting method must match the structure.

Pipework, Insulation and Heat Retention

Pipe routing and insulation are important on any solar geyser installation. Poorly planned pipework can create heat loss, untidy installation and future maintenance problems.

Insulated pipework helps protect the heat collected by the solar system. This is especially important where pipes are exposed to wind, cold weather or long roof runs.

For a compact 100L system, good insulation helps make better use of the stored hot water. Because the tank is smaller, unnecessary heat loss should be avoided wherever possible.

Valves, Pressure Control and Safety Components

A high-pressure solar geyser must include the correct valves and safety components. These parts help manage pressure, expansion, water flow and safe operation.

Important valves should be installed correctly and remain accessible for future inspection or maintenance. Poor valve placement can make servicing difficult and can create avoidable problems later.

The system should be installed by qualified plumbers because it connects to a pressurised hot water setup. Correct pressure control and safety valve arrangement are essential for reliable operation.
