Which Solar Geyser System Is Right for Your Property?
Every property is different. The best solar water heating system depends on your roof, geyser location, available space, hot water usage and installation requirements. We help customers understand the main system options before choosing an installation.
- Close-Coupled Thermosyphon System — the geyser and solar collector are installed together on the roof. Water circulates naturally when the system is correctly designed.
- Split Thermosyphon System — the collector is installed on the roof while the geyser is positioned separately, often inside the roof space. Natural circulation requires a suitable relative height and pipework layout.
- Pumped Solar System — a circulation pump moves water or heat-transfer fluid between the collector and storage tank. This can accommodate certain layouts where natural circulation is unsuitable.
- Flat-Roof Installation — a suitable mounting structure positions the collector on a flat or low-pitched roof. The installation can use different circulation configurations depending on the design.

Solar geyser or heat pump?
Let Us Help You Compare Your Options
Both solar water heating and hot water heat pumps can reduce reliance on conventional electric water heating. However, they operate differently and suit different installation conditions.
02
Domestic Hot Water Heat Pump
Extracts heat from the surrounding air and transfers it to water. It does not require a solar collector on the roof, although it does require suitable space and airflow.
03
What Guides the Choice
The best option depends on your hot water consumption, property layout, installation budget and expected operating costs. We can assess your requirements and explain the advantages and limitations of each option.
Existing geyser upgrades
Can Your Existing Geyser Be Converted to Solar?
You may not need to replace your existing geyser to benefit from solar water heating. Depending on its condition, capacity, pressure rating, position and compatibility, your existing geyser may be suitable for a solar retrofit.
For example, a geyser positioned inside the roof space may be connected to a suitable roof-mounted solar collector using an appropriately designed circulation arrangement. Some installations require a circulation pump or additional controls. Others may require a new geyser. We assess your current system and explain whether a retrofit is practical before you commit to the work.

Protect Your Hot Water System with Regular Servicing
Your solar geyser or heat pump is an important part of your property. Regular maintenance provides an opportunity to identify developing problems and keep track of the equipment’s condition.
Depending on your system, preventative maintenance may include checking visible leaks, inspecting valves, assessing the sacrificial anode where fitted, reviewing pump operation and inspecting accessible components. Our team can record the service findings, explain recommended repairs and help you plan your next maintenance visit. Maintenance requirements vary by equipment, manufacturer and water conditions.

Answers before you book
How much does a solar geyser installation cost?
The price depends on the system type, tank capacity, collector, roof layout, pipework and installation requirements. Contact us for an assessment and quotation.
Can you install a solar system using my existing geyser?
Possibly. We assess the geyser’s condition, compatibility, location and capacity before confirming whether a retrofit is suitable.
Is a heat pump better than a solar geyser?
Neither is automatically better for every property. A heat pump extracts heat from the air, while a solar geyser uses solar collectors. The best option depends on your requirements and installation conditions.
How often should a solar geyser be serviced?
Follow the manufacturer’s maintenance recommendations. The appropriate service interval can also depend on water quality, system design and operating conditions.
Do you repair heat pumps?
We assess heat pump faults and recommend suitable repairs, servicing or replacement where appropriate.
Do you provide quotations?
Yes. Contact us with your property details and the service you need so we can arrange an assessment and provide a quotation.
