Filtered Water Dispensers

A filtered water dispenser is a unit that combines a water treatment section and a hot-and-cold dispenser in a single body. Often called a mains-fed or bottleless water cooler, it supplies treated water continuously from the mains, with no carboys to carry, no stock to track and no empty containers to manage. It is chosen for shared areas such as offices, shops, waiting rooms, factories and schools.

With a filtered dispenser the choice starts with capacity and continues with hygiene and a maintenance routine. How it differs from a carboy dispenser, the installation requirements and the model types are the other headings that shape the decision.

How Does a Filtered Water Dispenser Work?

The unit has two sections. The first section is the treatment unit: mains water is treated by passing it through a sediment filter, activated carbon and, on most models, a reverse osmosis membrane. The second section is the dispenser unit: the treated water is taken into the cooling and heating tanks and served at the temperature you want.

The basic difference from carboy dispensers is that the water does not come from outside. The unit is connected directly to the mains line and feeds itself as water is drawn. For that reason "running dry" does not happen, other than during a mains interruption.

Heating and cooling capacities vary from model to model. Under heavy use what decides the outcome is not so much the tank volume as how quickly the tank reheats and chills again; that figure sets how many glasses can be served one after another.

Mains-Fed vs Bottled Water Dispenser

The clear advantage of a filtered dispenser is continuity and the disappearance of the operational load. In return it requires a water and a drain connection, so the installation point must be planned from the start. The running costs of both options are compared in our article bottleless dispenser or bottled water?

Filtered Water Dispenser Models and Types

Countertop Water Dispenser

Used where space is limited, such as small offices and shops. It is placed on a counter or a cabinet. To see the model: Countertop Water Dispenser.

Freestanding (Floor-Standing) Filtered Dispenser

This is the most common type in shared areas. The working height is comfortable and it offers a larger tank volume. To see the model: Filtered Water Dispenser.

Stainless Steel Body Models

Chosen for heavily used areas thanks to a body that is easy to clean and hard-wearing. A stainless steel body is available on both chilled and industrial models.

Chilled Water Dispenser

Its high cooling capacity stands out in warm environments and under heavy consumption. To see the model: Stainless Chilled Water Dispenser.

Bubbler (Drinking Fountain) Models

Allows use without a glass; common in schools, sports facilities and factory corridors. To see the model: Bubbler Water Dispenser with Treatment.

Industrial Dispensers and Industrial-Type Water Dispensers

Designed for high flow rate and durability at facilities with many users. To see the model: industrial stainless water dispenser.

Water Dispenser Dimensions

Where the dispenser will stand, door width, worktop space and ventilation clearance matter as much as its size. The values below are the dimensions and weights given on the product pages; leave extra space for the mains connection and rear ventilation.

How Is Capacity Chosen?

The most common mistake when choosing a dispenser is to look at the daily total and ignore peak demand. In offices water consumption is not spread evenly through the day; it concentrates at break times.

The headings that must be assessed:

• Number of users: The total number of people the unit will serve.
• Peak moment: How many people will be served one after another at break times.
• Hot water use: If tea and coffee consumption is heavy, heating capacity becomes the deciding factor.
• Cold water use: In hot climates and at facilities with heavy physical work, cooling capacity comes to the fore.
• Ambient temperature: Cooling takes longer in a warm room; capacity must be chosen accordingly.
• Number of points: Placing small units at several points instead of one large unit shortens the walking distance and can spread the load.

A unit chosen with too little capacity delivers lukewarm water and users start to complain; one chosen larger than needed creates an unnecessary initial outlay and unnecessary energy consumption.

Installation Requirements

Unlike a carboy dispenser, a filtered dispenser is connected to the plumbing. The following conditions must be settled before installation:

• Water connection: A cold water line must run nearby and it must be possible to fit an isolating valve.
• Drain: Models with reverse osmosis need a suitable drain for the wastewater line. This is the condition most often overlooked.
• Electricity: Heating and cooling need a continuous supply; the socket must be close to the unit and earthed.
• Floor and ventilation: A gap must be left behind the unit for heat dissipation, and it must be positioned away from direct sunlight and from heat sources.
• Service access: Access clearance must be left in front of or beside the unit for filter replacement.
• Water pressure: If the pressure is low the reverse osmosis yield falls; a model with a pump should be considered.

Where there is no drain, models without reverse osmosis that use filter stages can be considered. That choice depends on the raw water quality and must be made on the basis of an analysis.

Hygiene and Cleaning

On dispensers the point most often missed is not the treatment but the hygiene of the service point. However well the water is treated, the expected benefit falls if the tap outlet and the drip tray are not kept clean.

• Tap outlet: This is the part that hands and glasses touch; it must be cleaned regularly.
• Drip tray: The collected water must be emptied and the tray must be washed.
• Outer surface: In shared areas this is the surface that is touched most often.
• Internal tanks: These are cleaned as part of scheduled maintenance; they must not be opened by the user.
• Long periods without use: After a holiday or a shutdown, some of the first water should be run off.

In shared areas with water dispensers, naming someone responsible for cleaning is the most effective solution in practice. When no one is named, the job is usually left undone.

Which part of the dispenser is cleaned by whom and how often is explained step by step in our guide Water Dispenser Maintenance: A Routine That Works.

Filter Replacement and Maintenance

Replacement intervals can shorten with heavier use and with poorer raw water quality. On a busy office unit the filters tire faster than on a lightly used one. At Water Point, filters, membranes, valves, pumps and tanks are covered as spare parts and consumables.

Fault Symptoms and First Checks

• The water comes out lukewarm: Too many servings may have been drawn in a row; wait for the tank to chill again. If it keeps happening, the capacity is too small.
• The flow has weakened: The pre-filters may be clogged, or the inlet pressure may have dropped.
• No water comes out: The inlet valve may be closed, the filter may be completely blocked, or the power may be off.
• The taste has changed: The post-carbon filter may have reached the end of its life.
• Wastewater runs non-stop: On models with reverse osmosis this may be a faulty shut-off valve or check valve.
• Water pooling under the unit: There may be a leak at a fitting or a hose connection; the unit must be switched off and service must be called.
• No hot water: The heating function may be switched off, or the safety lock may be engaged.

Use in Offices and Businesses

In a business, filtered dispensers deliver not only a water supply but also a simplification of operations. Tasks such as ordering carboys, tracking deliveries, managing stock and returning empty containers disappear.

In return a new responsibility appears: keeping track of filter replacement. In practice the most common problem is not a unit fault but a forgotten filter change. To prevent this:

• Replacement dates must be put in a calendar and someone must be made responsible.
• The date of the last replacement must be noted on the unit.
• At businesses with several units, all of them must be tracked on a single list.
• If a scheduled maintenance service is taken, its scope must be set out in writing.

At facilities with many users, placing units at several points instead of one large unit both spreads the load and keeps the whole site from being left without water when one unit fails.

The Taste and Quality of Dispenser Water

The first thing users judge a dispenser by is the taste of the water. Three factors decide the taste, and all three can be managed.

• Chlorine: Free chlorine in mains water is the most common cause of taste and odour. The activated carbon stage removes this component; when the carbon reaches the end of its life, the chlorine taste returns.
• Dissolved minerals: The reverse osmosis stage separates out most of these. Some users find completely mineral-free water "flat"; a mineral cartridge can be used in that case.
• Standing water: Water that stands in the tank for a long time can lose taste. On lightly used units, running off some water at the start of the day improves the taste noticeably.

When a taste complaint comes in, the first place to check is the post-carbon stage; this filter gives the water its final taste polish, and when it reaches the end of its life the effect is felt at once.

How Many Units, and Where?

At businesses spread over several floors or a large area, placing units at more than one point usually gives a better result than a single large unit.

• Walking distance: Where people have to walk a long way for water, use falls off; units must be positioned close to the work areas.
• Spread of demand: A queue forms in front of a single unit at break times. Several points spread that build-up.
• Risk of breakdown: When the only unit fails, the whole site is affected; a second point provides redundancy.
• Planning floor by floor: One point on each floor reduces vertical traffic noticeably.
• Infrastructure cost: Every point requires a water and a drain connection; the planning must be done together with what the plumbing allows.

Common Mistakes When Choosing a Dispenser

• Looking only at the number of users: If the peak moment is not taken into account, the water comes out lukewarm and the complaints start.
• Not planning the drain line: Models with reverse osmosis cannot be installed without a wastewater line.
• Not keeping track of filter replacement: This is the most frequent problem; the unit keeps running but the water quality falls.
• Putting the unit next to a heat source: Cooling efficiency falls and energy consumption rises.
• Leaving no gap behind it: Heat dissipation is blocked and the compressor is put under strain.
• Not thinking about service access: On a unit squeezed between cabinets, filter replacement becomes difficult and gets postponed.
• Neglecting tap hygiene: However good the treatment is, the benefit falls if the service point is dirty.

What to Prepare Before Requesting a Quote

1. Number of users: The total number of people the unit will serve.
2. Peak moment: How many servings are expected one after another at break times.
3. Hot and cold balance: Whether tea and coffee consumption is heavy, or demand for cold water dominates.
4. Installation point: The state of the water line, the drain and the socket.
5. Water pressure: If it is low, a model with a pump may be needed.
6. Setting: Temperature, footfall and whether children will use it.
7. Maintenance: Who will keep track of filter replacement, and whether a service contract is wanted.

Once these seven headings are clear, the right capacity is chosen and nothing is paid for features that are not needed. The peak moment and the drain situation in particular must be settled before a quote is issued.

The Difference Between a Filtered Dispenser and an Under-Sink Unit

Both treat mains water, but they are used differently, and the right choice depends on what the setting needs.

An under-sink unit hides inside the kitchen cabinet, is used with a separate filter tap and delivers water at room temperature. It takes up no visible space and costs less. In return it does not serve hot or cold water; heating or chilling the water is left to the user.

A filtered dispenser, on the other hand, brings treatment together with hot and cold water service at a single point. It gives a clear advantage in shared areas, in settings with many users and where tea and coffee consumption is heavy. It takes up floor space and costs more.

The practical distinction is this: for a home or a small office that has a kitchen and heats its own water, an under-sink unit is enough. Where a shared area needs quick service and there are many users, a filtered dispenser is the right choice. Some businesses use both: an under-sink unit in the kitchen and a dispenser in the shared area.

Commissioning and First Use

On a newly installed dispenser, or one whose filters have just been changed, the first water produced is not used. Carbon dust from the cartridges and manufacturing residues are carried away with it.

• After the unit is commissioned, a few litres of water are run off and discarded.
• The heating and cooling functions are switched on after the tanks have filled; the heater must not be run with an empty tank.
• Slight cloudiness or bubbles may be seen in the first water; this comes from air and clears in a short time.
• On first start-up, the hot water function must be left for a while until it reaches the target temperature.
• The same procedure is repeated on units that have not been used for a long time.

Noting the filter replacement date on the unit during commissioning is the simplest and most effective way to keep the next service from being forgotten.

Use by Sector

Offices and Business Centres

Consumption concentrates at break times and fluctuates through the day. Demand for hot water is high because of tea and coffee. Positioning floor by floor prevents a build-up at a single point. Appearance and quiet running are the criteria that stand out in these settings.

Factories and Production Facilities

The number of users is high and demand rises sharply at shift changes. Cold water consumption dominates, especially in hot production areas. Stainless steel body or bubbler models are preferred for their durability and ease of cleaning.

Schools and Educational Institutions

High demand builds in a very short time at break periods. Bubbler models are common because they allow use without a glass. Hot water safety must be assessed with particular care in these settings; a child lock, or switching the hot water function off, can be considered.

Shops, Showrooms and Waiting Rooms

Use is relatively light, but the unit stands where the customer can see it. Appearance, quiet running and cleanliness come to the fore. Countertop or compact freestanding models are usually enough.

Healthcare and Care Institutions

Hygiene monitoring and a regular maintenance record become important. Planned cleaning of the service point and keeping filter replacement records must be made standard practice in these settings.

Service Life and Long-Term Use

What decides the life of a filtered dispenser is not so much the quality of the body as the discipline of maintenance. A unit whose filters are changed on time, which runs in a suitable position and is cleaned regularly serves for many years without trouble.

The main factors that shorten its life are these:

• Postponing filter replacement: Clogged pre-filters put the pump and the membrane under strain; delaying the cheap part wears out the expensive one.
• Inadequate ventilation: On a unit with no gap behind it the compressor is under constant strain and its life is shortened.
• High ambient temperature: On a unit placed next to a heat source the cooling never gets a rest.
• Hard water: Limescale build-up in the heating tank speeds up; in areas where hardness is high a pre-treatment stage becomes important.
• Voltage fluctuations: These have a wearing effect on the compressor and the electronic board.

When these headings are taken into account at the installation stage, the unit runs steadily for far longer than expected. After installation the only deciding factor is the maintenance schedule.

Practical Tips for Saving Energy

Because filtered dispensers run continuously, their energy consumption is uninterrupted. Small adjustments can cut this consumption noticeably.

• Switching the heating off outside working hours: If there is no need for hot water at night and at weekends, the heating function can be switched off. When it is switched back on in the morning, it is ready in a short time.
• Correct positioning: Placing the unit out of the sun and away from heat sources such as radiators and ovens reduces the cooling load.
• Rear clearance: The gap left for heat dissipation lets the compressor reach its target sooner.
• Choosing the right capacity: A unit larger than needed keeps heating and chilling a volume that is never used.
• Using a timer: With the timer found on some models, the operating hours can be set to match the working day.

These measures lower the running cost without giving up any performance. At businesses with several units in particular, the total effect is noticeable.

Rental or Purchase?

A business can meet its dispenser requirement through two different commercial models, and the right choice depends on how long the unit will be used and on the preferred maintenance arrangement. With a purchase, ownership of the unit passes to the business; the initial outlay is high, but over the long run the total cost usually stays lower. Maintenance and filter tracking are the responsibility of the business, which can work with whichever service provider it wishes.

With the rental model the initial outlay is low or nil; maintenance and filter replacement are mostly carried out under the contract. It offers a practical solution on short-term projects, on construction sites and in organisations where the number of units changes often. When deciding, the length of use, who will carry the maintenance load and whether the number of units will change over time must be assessed together.

Energy Consumption and Running Cost

The cost of a filtered dispenser is made up of three items: the price of the unit, consumables and energy.

• Filter set: The pre-filters are usually replaced twice a year; this is the most regular cost item.
• Membrane: On models with reverse osmosis it is renewed every few years.
• Electricity: Because heating and cooling run continuously, there is a fixed level of consumption. Being able to switch the heating off in the hours when the unit is not used lowers it.
• Wastewater: On models with reverse osmosis some water goes to the drain.
• Service: Scheduled maintenance and tank cleaning.

When making the comparison, the carboy side must be counted not only as the price of the carboy; the items that do not show up, such as handling, storage space, order tracking and empty-container management, must be taken into account as well. With a filtered dispenser these items disappear and filter discipline takes their place.

Hot Water Safety

On dispensers used in shared areas, hot water calls for care, especially where children are present. The following must be assessed when the unit is chosen and positioned:

• Child lock: A safety lock on the hot water tap matters in areas used by schools and families.
• Tap height: The position of the unit can be planned so that small children cannot reach it easily.
• Warning label: The hot water outlet needs to be clearly marked.
• Switching the heating off: Where it is not needed, the hot water function can be switched off; this is an advantage for both safety and energy.

When Are Bubbler Models Preferred?

Bubbler (drinking fountain) dispensers let people drink directly without using a glass. They are common in places such as schools, sports facilities, factory corridors and parks.

Their advantages are that glass use and the waste that goes with it disappear, and that use is quick. The point to watch is the hygiene of the bubbler nozzle; the nozzle must be cleaned regularly and the water jet must be set so that it does not touch the nozzle directly.

In office settings where people prefer to use a glass, models with a standard tap suit better. Some models carry both options together.

Stainless Steel Water Coolers for Factories and Schools

In heavily used shared areas the body material matters for hygiene and durability as much as for the look of the unit.

• Ease of cleaning: A stainless steel surface does not hold marks and wipes clean easily.
• Durability: It stands up better to knocks and scratches; in busy thoroughfares it lasts longer.
• Appearance: It offers the look that is preferred in corporate spaces.
• Heat resistance: There is less material fatigue in the hot water section.

While standard-body models are enough in lightly used small offices, in busy places such as factories and schools a stainless steel body can be more economical over the long run. For a model with cooling as standard, see the stainless steel water cooler with treatment.
