100 Litre Solar Geyser Evacuated Tube Conversion System

A 100 litre system is best for 1 to 2 occupants, small flats, granny flats, garden cottages, outside rooms or low-demand bathrooms where hot water is used carefully.

Yes. Supply-and-install enquiries include installation by our plumbing team, and the completed plumbing work includes a plumbing CoC where required. The final quote confirms roof access, pipe routing, valve changes, controller work and any compatibility issues before work starts.

Yes, where a plumbing CoC is required for the completed geyser installation or conversion work, it is included as part of the compliant plumbing handover. The system must be installed with correct valves, safe discharge routing, pressure control and accessible service points.

Yes. These pages are only for solar geyser and solar hot-water conversion systems. They do not cover inverters, batteries, general solar power systems or household electrical solar panels.

Yes. GeyserWise control can be included where the system design supports it. It helps with temperature display, booster timing, solar circulation behaviour and customer handover after installation.

We can discuss options and compatibility around Kwikot, Heat Tech, ITS, Megasun, Solahart, SunTank, Chromagen, GeyserWise, Duratherm, Alliance Solar and Solar Shine, depending on availability and the installation requirements.

The existing geyser condition, roof access, pipe route, pressure rating, valves, drain points, controller position, collector placement, shade, safety discharge and future service access must all be checked before the final recommendation is made.

The system uses available stored heat first. When solar gain is not enough, the electrical backup element can assist according to the controller settings and the household hot-water demand.

Evacuated tube collectors can still collect useful heat during cooler seasons, but performance depends on sunlight, collector sizing, insulation quality, pipe runs, water usage and backup heating control.

Sometimes, but an old, leaking, rusted, undersized or badly positioned geyser may be better replaced first. Reusing a weak tank can waste money and reduce the benefit of the conversion.

A correctly sized and configured solar geyser conversion can reduce reliance on the electrical element. Savings depend on usage habits, weather, insulation, collector performance and how the backup heating schedule is managed.

Yes. Safe roof access affects the installation time, collector position, pipe routing, waterproofing, future maintenance and the final quote.

Yes. The installation should be planned with future service access in mind so valves, sensors, pumps, controllers, collectors and pipe insulation can be inspected or replaced later.

Photos of the current geyser, roof area, visible valves, controller, pipework and electrical isolator are useful. Also mention how many people use hot water and when the highest demand normally happens.

No. A cheaper system can cost more later if the collector is undersized, valves are wrong, pipework is poorly insulated, the controller is not configured, or the installation is difficult to service.

Each page explains size suitability, installation requirements, CoC considerations, GeyserWise control, valve checks, roof planning, maintenance access and related plumbing services so the customer can make a more informed decision.

A plumbing CoC is included where required for the completed installation. The system still needs to be assessed on site because roof access, pressure control, valve changes and pipe routing can affect the final scope.

In some cases the existing geyser can be reused, but only if the tank, pressure rating, valves, element, thermostat and general condition are suitable. A leaking, badly corroded or unsafe geyser should be repaired or replaced before conversion.

Many evacuated tube systems allow individual damaged tubes to be replaced, provided the collector design and available parts support it. The collector condition should be checked before replacing only one part.

The solar side can still collect heat when sunlight and system design allow it. Electrical boosting, pumps and controllers depend on the specific setup and available power, so this must be discussed during assessment.

A practical check once a year is recommended. Valves, insulation, pipework, collector condition, sensors, GeyserWise settings and signs of leaks should be inspected.

Common brands and components include Kwikot, Heat Tech, ITS, Megasun, Solahart, SunTank, Chromagen, Duratherm and GeyserWise controllers. Final compatibility depends on the existing system and the conversion design.

Yes, but it is better to size the system correctly from the start. Upgrading later may require changes to storage, collector area, pipework, valves, roof layout and controller settings.

A leaking geyser should not be treated as a simple conversion candidate. The leak must be assessed first, and replacement may be safer before adding solar collector and control equipment.

Check whether the quote includes installation, valves, controller work, collector mounting, pipe insulation, testing, handover and plumbing CoC where required. Also confirm whether any electrical work is excluded.
