THE COMPLETE BUYING GUIDE
Choosing the Right Water Dispenser in South Africa
A practical guide to water dispensers for homes, offices, schools and commercial environments.
Choosing a water dispenser can seem straightforward until you start comparing the options. Should you choose bottled or bottleless? Hot and cold or cold and ambient? Do you need built-in filtration? How much water does your household or workplace actually need?
The right water dispenser should make drinking water convenient while matching the number of people using it, the available water supply, the space in which it will be installed and the way you prefer to drink your water.
In this guide, we explain the different types available in South Africa, how they work, what they cost and what to consider before buying or renting one.

THE BASICS
What Is a Water Dispenser?
A water dispenser is an appliance designed to provide convenient access to drinking water. Depending on the model, it may dispense chilled, ambient-temperature or hot water.
Water can be supplied in several ways: a traditional bottled dispenser uses a large bottle—commonly 18.9 litres—positioned on top; a filtered dispenser can use a refillable purifier bottle; and an inline or bottleless model connects directly to the building's mains water supply and filters the water before dispensing it.
A modern dispenser can do much more than hold a bottle. Frost's inline model connects to mains water, uses two-stage filtration and compressor cooling to produce chilled water.
Water dispenser vs water cooler: what's the difference?
Water dispenser is the broader category for appliances that dispense drinking water. A water cooler generally describes a dispenser capable of actively cooling it.
A basic gravity-fed unit can therefore be a water dispenser without being a cooler. Most modern electric dispensers incorporate refrigeration and perform both functions. For most shoppers, the useful question is not the terminology, but the water supply, temperature options and filtration you need.
THE BIG DECISION
Bottled vs Bottleless Water Dispensers
One of the most important decisions is how you want to supply water to your dispenser.
Bottled
A replaceable water container—typically 18.9L—feeds the dispenser. No plumbing connection is required.
- Simple installation
- Flexible positioning
- No permanent plumbing
- Ideal where mains access is difficult
Keep in mind: bottles must be bought or refilled, transported, stored and replaced.
Bottleless / Inline
A connected water line supplies the machine continuously and built-in filters treat the water before dispensing.
- No heavy bottles to replace
- No bottle storage
- Continuous water supply
- Integrated filtration
Keep in mind: installation requires an appropriate mains connection.
| Choose bottled if… | Choose inline if… |
|---|---|
| You want minimal installation | You have a suitable mains connection |
| The dispenser may be moved | It will stay in one location |
| Consumption is moderate | Consumption is relatively high |
| Bottle storage is not a problem | You want to eliminate bottle storage |
For many homes and small offices, either system can work well. For busy offices, schools and commercial environments, the convenience of an inline system becomes increasingly valuable.
TEMPERATURE OPTIONS
Hot & Cold vs Cold & Ambient
Hot & Cold
Chills drinking water and maintains hot water for tea, coffee and instant beverages. Frost freestanding models use 90W compressor cooling and a 500W heating system, with listed capacities up to 2.8L chilled and 5L hot water per hour.
View hot & cold dispensers →Cold & Ambient
Provides chilled water from one outlet and room-temperature water from another, without continuously maintaining a hot-water reservoir. It is a simpler choice when drinking water is the primary requirement.
View a cold & ambient model →Neither is inherently better. Choose hot and cold when hot beverages are regularly prepared at the dispenser; choose cold and ambient when you mainly need drinking water.
WATER QUALITY
What About Built-In Filtration?
The source of the water and the filtration system are separate considerations. A dispenser can simply dispense bottled water, or it can treat the water before dispensing it.
Purifier & mineraliser filter bottle
Selected Frost dispensers use a refillable purifier and mineraliser bottle with a carbon combination filter. This adds filtration while retaining the flexibility of a freestanding dispenser.
View the hot & cold filtered dispenser →Inline filtration
A direct mains-fed dispenser treats incoming water with a two-stage inline filtration system. It is useful where you want filtered drinking water without continually filling or replacing bottles.
View the inline filtered dispenser →Frost also supplies standalone two-stage countertop and under-counter systems where water purification is required independently of a dispenser.
BY ENVIRONMENT
Best Water Dispensers for Home Use
For a home, consider available space, the number of people, preferred water temperature and water source first. A family that drinks chilled water and frequently makes tea or coffee may benefit from hot and cold. If hot water is not required, cold and ambient is simpler.
Hot & cold with filter bottle
Combines hot and chilled water with a purifier/mineraliser bottle and carbon filtration.

Best Water Dispensers for Offices
Office needs differ because many more people may use one dispenser during the day. Consider employee count, daily use, peak demand, the available mains connection, bottle storage, tea and coffee consumption and maintenance.
A bottled or filter-bottle unit can suit a small office. As usage grows, replacing 18.9L bottles becomes inconvenient and an inline office dispenser becomes more attractive. Frost's inline model filters incoming mains water and provides up to 2.8L of chilled water per hour.

Best Water Dispensers for Schools
Schools share many office requirements, but capacity and simplicity are especially important. A staff room has different needs from a high-traffic learner drinking point. Consider the number of users, installation position and whether a mains connection is available.
An inline system removes the need to transport and replace large bottles where plumbing is convenient. Bottled or filter-bottle systems can suit smaller staff areas or classrooms. For very high demand, consider a dedicated drinking-water fountain or higher-capacity solution instead of one domestic-style dispenser.
RUNNING COSTS
How Much Electricity Does a Water Dispenser Use?
Rated power is not the same as continuous consumption. A 90W cooling compressor and 500W heating system cycle on and off to maintain their set temperatures.
Actual consumption depends on room temperature, dispensing frequency, water volume, incoming water temperature, settings, insulation and whether the hot-water function remains switched on.
If hot water is rarely used, cold and ambient may be more appropriate. For exact energy consumption, consult the specification for the individual appliance rather than estimating from its maximum wattage alone.
BUDGETING
How Much Does a Water Dispenser Cost in South Africa?
Prices vary by configuration, filtration, water supply, size and functionality. Frost's current range illustrates the difference: basic bottled and desktop models generally sit lower, while filtration and direct mains-fed systems cost more.
Consider the full setup rather than purchase price alone: dispenser + water supply + filters + maintenance + electricity. Bottled units require an ongoing water supply. Inline models cost more initially and need installation, but remove bottle handling and storage.

How Do You Choose the Right Capacity?
Do not simply buy the largest machine you can find. Consider peak demand. Twenty employees may have manageable average consumption, but if ten arrive during one lunch break, cooling capacity matters much more.
Compare cooling capacity, cold-water reservoir/output, heating capacity and water source. Bottle-fed units are limited by bottle volume while inline systems have a continuous supply. Busy workplaces, schools and commercial environments may need multiple dispensing points or a higher-capacity solution.
CARE & HYGIENE
How Often Should You Clean a Water Dispenser?
Wipe the exterior, taps and dispensing area; empty and clean the drip tray.
Inspect and clean the bottle-contact or loading area where appropriate.
Sanitise internal water-contact components according to the manufacturer's instructions.
Procedures vary between bottled, filtered and inline models. Avoid introducing unsuitable household chemicals into the water system. For commercial installations, use a documented maintenance routine.
FILTER MAINTENANCE
How Often Should Filters Be Replaced?
There is no universal replacement interval. Filter life depends on filter type, incoming water quality, water volume, manufacturer specifications, sediment, chlorine and frequency of use.
Follow the interval for the particular filter installed. A busy office may process much more water than a two-person household using the same system.

Renting vs Buying a Water Dispenser
For households, buying outright is usually the obvious route. Businesses can also consider a rental and service contract.
Buying may suit you when…
- You want to own the equipment
- Usage is predictable
- You can handle maintenance
- You do not need a service agreement
Renting may suit you when…
- You prefer predictable monthly costs
- Maintenance is important
- You want a lower upfront cost
- Servicing should be included
Compare total cost and the service included over the full contract—not only the monthly rental against the purchase price.

Common Water Dispenser Problems
01Water is not cooling
Check that the unit has power, cooling is switched on and ventilation is adequate. If the compressor operates but cooling is poor, arrange professional inspection.
02Water is not heating
Confirm the separate heating switch is on. If it still does not work, arrange an inspection rather than dismantling electrical parts.
03Water tastes or smells different
Check the incoming supply, filter service interval, bottle condition and cleaning schedule. Stop use if the safety of incoming water is uncertain.
04Water flow is slow
On filtered models this can indicate a filter near the end of its service life, although other restrictions can cause the same symptom.
05The dispenser is leaking
Check whether the drip tray is full and, on bottled systems, inspect bottle seating. If the appliance itself keeps leaking, disconnect it as appropriate and arrange an inspection.
