The SUPAHOT 150L electric geyser is a high-capacity domestic water heater engineered for South African residential plumbing. Rated at 3 kW, 230 V and 400 kPa, it holds 150 litres of hot water — enough for a household of 4 to 6 people across baths, showers, kitchen and laundry. The unit is NRCS-approved under Letter of Authority certificate ZAF-WH-0003208 (compliance with SANS 151:2017) and carries a 5-year manufacturer warranty on the inner cylinder. Energy efficiency class B, Proudly South African.
Designed for both horizontal (roof-space) and vertical (floor or wall) installation, the SUPAHOT 150L fits standard South African geyser cavities and uses common 3/4" BSP female inlet and outlet connections — no special fittings required. The replaceable 3 kW heating element and magnesium sacrificial anode are standard parts available at most plumbing merchants, simplifying long-term maintenance.

Who this geyser is for
The 150-litre capacity is the most common size specified by South African plumbers for medium-sized households — large enough to run two showers back-to-back without running cold, while still fitting standard roof-space cavities. The 400 kPa working pressure matches typical SA residential municipal supply, so no specialist pressure-reducing valve is required beyond the factory-supplied safety valve.
Installation requirements
This geyser must be installed by a qualified plumber and wired by a qualified electrician in compliance with SANS 10254 (installation of fixed electric storage water heaters) and SANS 10142 (electrical wiring). A vacuum breaker and safety drip tray are required and sold separately — see our Pressure Control Valves and Geyser Trays range.
Long-term maintenance
The magnesium sacrificial anode protects the inner cylinder from corrosion and should be inspected every 2 to 3 years and replaced as needed to maximise the geyser's service life. Standard 3 kW elements and thermostats are widely stocked and serviceable by any qualified plumber.
Frequently asked questions
How many people does a 150L electric geyser serve?
A 150-litre electric geyser comfortably serves a household of 4 to 6 people. It is the most commonly specified size by South African plumbers for medium-sized family homes because it provides enough hot water for two back-to-back showers and everyday kitchen use without running cold.
Can the SUPAHOT 150L be installed horizontally or vertically?
Yes — this model is designed for both horizontal (roof-space) and vertical (floor or wall) installation. The unit uses standard 3/4" BSP female inlet and outlet connections spaced 1240 mm apart, so it fits the majority of existing South African geyser cavities without modification.
Is the SUPAHOT 150L geyser NRCS approved?
Yes. The SUPAHOT 150L electric geyser is NRCS-approved under Letter of Authority certificate number ZAF-WH-0003208, confirming compliance with SANS 151:2017 Ed. 8.1 — the South African national standard for fixed electric storage water heaters. The unit carries NRCS energy efficiency class B labelling.
Does this geyser need a pressure-reducing valve?
The maximum working pressure is 400 kPa, which matches typical South African residential municipal supply. A factory-supplied safety valve rated at 400 kPa is included. If your incoming water pressure is higher than 400 kPa (some regions), a separate pressure-reducing valve is required — ask your plumber to check at installation.
How long does the SUPAHOT 150L take to heat up from cold?
Heating 150 litres from 25 °C to 65 °C at 3 kW takes approximately 2 hours 20 minutes under ideal conditions. In practice, allow around 2.5 to 3 hours from a fully cold start, and 30 to 60 minutes to recover after a typical shower cycle.
How often should the magnesium anode be replaced?
Inspect the magnesium sacrificial anode every 2 to 3 years, or sooner in areas with hard or aggressive water (parts of Gauteng and Eastern Cape, for example). The anode protects the cylinder wall from corrosion; replacing it on schedule can significantly extend the service life of the geyser beyond the 5-year warranty period.
What's included in the box?
The SUPAHOT 150L ships as a complete electric geyser cylinder with a factory-fitted 3 kW heating element, thermostat, magnesium anode, 400 kPa safety valve and draincock. A vacuum breaker and safety drip tray are required for installation and are sold separately — see our Pressure Control Valves and Geyser Trays range.
How long is the warranty and what does it cover?
The SUPAHOT 150L carries a 5-year manufacturer warranty on the inner cylinder. The warranty is conditional on installation by a qualified plumber in compliance with SANS 10254 and SANS 10142, and on scheduled anode inspection and replacement. Consumables (element, thermostat) are covered under a shorter component warranty — retain the installation invoice for any claim. Warranty centre: 087 255 5468 or 079 782 9468 (STAY HOT).
