  • Direct vs. Indirect Systems: Direct systems heat water directly in the collector, while indirect systems use a heat exchanger, ideal for areas with hard water or frost.
• Geyser Capacity: Larger tanks for more hot water will naturally cost more.
• Collector Type: Flat plate collectors and evacuated tube collectors have different costs and efficiencies.
• Roof Type and Access: The ease of installation on your roof can influence labour costs.
• Additional Components: This might include pumps, controllers, and extra piping if a new system is being installed from scratch.

‍

Typical Solar Geyser Unit Costs:

• Low Pressure Systems (e.g., 100L - 150L): R6,000 - R14,000
• Closed Coupled High Pressure Systems (e.g., 150L - 300L): R12,000 - R25,000
• Direct Thermosiphon Systems: R12,000 - R25,000
• Indirect Thermosiphon Systems: R12,000 - R25,000

‍

Typical Solar Geyser Installation Labour Costs:

The installation cost for a solar geyser, excluding the unit itself, can range from R4,500 upwards. Some providers offer packages that include the unit and installation, with prices for a full system (e.g., 150L high-pressure) starting from R14,000 to R20,000+.

‍

General Cost Factors for Geyser Installation (Gas & Solar)

• Location: Prices can vary based on your geographic location within South Africa due to regional labour rates and material availability.
• Complexity of the Job: A straightforward replacement of an existing geyser will be less expensive than a new installation that requires extensive plumbing, gas line routing, or structural modifications.
• Accessibility: If the geyser is in a difficult-to-reach location (e.g., a cramped attic or a high roof), it might increase labour costs.
• Additional Work: Sometimes, old piping might need replacement, or new electrical circuits might be required (for electric backups in solar systems), adding to the overall cost.
• Emergency Service: Needing immediate installation due to a burst geyser, for example, can incur higher fees.

Cost Breakdown (Applicable to Plumbing Service Category)

• Call Out Fee: This is a fee charged by plumbers to cover their travel time and initial assessment. It typically ranges from R450 - R650. Some plumbers might include the first hour of labour in this fee.
• Emergency Fee: For urgent services outside of standard business hours or on weekends/public holidays, an emergency fee is applied. This can add 50% to 100% to the standard hourly rate or result in a higher call-out fee, often around R750 - R1,000.
• After Hours Rate: Similar to emergency fees, plumbers charge higher rates for services rendered after normal working hours (e.g., after 5 PM and before 8 AM). This premium typically increases the hourly rate by 50% to 100%.
• Cleaning or Disposal Fee: If old materials or the old geyser need to be removed and disposed of responsibly, a separate fee might be charged. This can vary, but expect to budget R200 - R500 depending on the size and type of geyser.
• Typical Materials Cost: The cost of materials for a geyser installation (excluding the geyser unit itself) includes items like piping, fittings, valves (pressure control valve, safety valve, vacuum breakers), drip trays, insulation, and electrical components. For a standard installation, this can range from R1,000 - R3,000, depending on the extent of new piping required and the quality of components.
• Typical Labour Cost: The labour cost for a geyser installation (gas or solar) typically ranges from R2,000 - R3,500 for a straightforward replacement. For more complex new installations, it can go up to R9,000 or more, depending on the hours required and the skill involved. This often excludes the cost of the geyser unit itself.
