What Is an Under Basin Geyser? Over Basin, Undercounter, Compact Geyser

An under basin geyser, also known as a mini geyser, undercounter geyser,  under sink geyser, over basin or point-of-use water heater, is a compact electric water heater installed inside the cabinet beneath a basin or sink. Instead of waiting for hot water to travel from the main geyser through long pipework, hot water is produced at the point of use, providing faster delivery while reducing unnecessary water and electricity consumption.

Under basin geysers are commonly installed in:

• Residential kitchens
• Guest bathrooms
• Office kitchens
• Hair salons
• Restaurants
• Coffee shops
• Medical practices
• Staff kitchens
• Retail stores
• Workshops

Is an Under Basin Geyser Right for Your Property?

An under basin geyser is an excellent choice if you experience any of the following:

• Long delays before hot water reaches the tap.
• Water is wasted while waiting for hot water.
• The existing geyser is too far from the kitchen or basin.
• You’re renovating a kitchen or bathroom.
• You need independent hot water for an office or commercial workspace.
• You want to reduce unnecessary energy consumption.

If your property already has hot water issues affecting multiple outlets, our plumbers can also inspect your complete plumbing system and recommend the most suitable solution.

Under Basin Geyser Replacement

Older units eventually become inefficient, develop leaks or suffer internal corrosion. Replacing an ageing under basin geyser can improve performance while reducing future maintenance costs.

Replacement is often recommended when:

• The tank is leaking.
• Rust is visible on the cylinder.
• Water is no longer heating correctly.
• The geyser repeatedly trips the electrical supply.
• Replacement parts are no longer available.
• Repair costs exceed the value of a new unit.

If the problem extends beyond the geyser itself, we can also inspect connected pipework and carry out any necessary plumbing repairs.

Common Under Basin Geyser Problems

Our technicians regularly repair faults including:

No Hot Water

Faulty heating elements, thermostats, electrical faults or damaged components.

Water Leaking Beneath the Sink

Leaks may originate from valves, pipe connections, fittings or the geyser tank itself.

Electrical Tripping

Repeated tripping often indicates an electrical fault, damaged element or insulation failure requiring professional testing.

Water Not Heating Properly

Incorrect thermostat settings or worn heating elements can reduce heating performance.

Pressure Valve Leaking

Pressure control components may require replacement to restore safe operation.

If your property experiences electrical issues beyond the geyser installation, our experienced electricians can diagnose and repair the underlying fault.

Frequently Asked Questions

How long does an under basin geyser installation take?

Most standard installations are completed within a few hours, depending on access, plumbing modifications and electrical requirements.

Can an under basin geyser supply more than one tap?

Some models can supply two nearby outlets, but the correct size depends on your expected hot water demand.

Does an under basin geyser reduce electricity usage?

Because water is heated close to where it is used, less energy is wasted keeping long pipe runs hot, and less water is wasted while waiting for hot water to arrive.

Can an under basin geyser replace a conventional geyser?

No. These compact units are designed to supply individual basins or sinks rather than an entire home’s hot water system.

Do I need both a plumber and an electrician?

Yes. Safe installation generally requires both plumbing and electrical work to ensure the system operates correctly and complies with applicable standards.

Can you replace an existing under sink geyser?

Yes. Existing units can usually be removed and replaced with a new under basin geyser during the same appointment if the installation remains suitable.
