Water cooler types: which option fits your needs

Water coolers are categorized depending on supply and use. There are mains-fed cooler models for continuous access to clean water, bottled water coolers for flexibility without permanent installation, as well as countertop or freestanding coolers for home and professional spaces. The right water cooler choice depends on consumption, available space and the level of convenience you want.

Mains-Fed Water Cooler with Filter vs Bottled Water Cooler – Which one should I choose?

If you’re wondering which water cooler is better, the answer depends on 3 things: access to a water supply, consumption and day-to-day convenience. Below is a simple guide to help you decide quickly.

1) Mains-Fed Water Cooler (with filter) – Ideal for convenience & savings

• No more carrying – no more bottles and bottled-water orders.
• Stable supply of filtered water whenever you need it.
• Less plastic – a more eco-friendly choice for home/office.
• Better for frequent use (family, office, high-traffic areas).

2) Bottled Water Cooler – Ideal for flexibility without installation

• No connection to the mains – place it wherever you want.
• Quick solution for spaces where installation is not convenient.
• Good option for low/medium consumption or temporary needs.
• Easy set-up – simply replace the bottle when it runs out.

▶ See all models here: Bottled Water Coolers

Quick decision in 15 seconds

• I want maximum convenience, less plastic and stable water flow → Mains-fed with filter.
• I don’t want/can’t install it and want portability → Bottled.
• I have many people (office/waiting area) → usually mains-fed is more practical.

Water coolers for professional spaces and higher consumption

For offices, businesses and spaces with increased drinking-water needs, water coolers for professional spaces offer stable performance, high hygiene levels and reliability in everyday use. Choosing the right water cooler for a professional environment helps reduce costs, ensures continuous availability of cold and hot water, and improves the experience for employees and visitors.

Hygiene & Ecology: Clean Water, Safety and Less Plastic

Many competitors emphasize “hygiene” and “eco-friendliness” — and rightly so. At OASIS, we approach it practically: with proper materials, proper maintenance and filtration options that truly make a difference in everyday consumption.

Hygiene & Safety in practice

• Cleaning & maintenance: with proper cleaning and regular service, you maintain consistently high water quality.
• Proper materials and construction for daily use, aiming for safe contact with drinking water.
• Mains filters (where applicable): reduce chlorine, odors and particles, making water more pleasant to drink.
• Certifications (such as CE, TÜV, RoHS): an additional sign of compliance and safety.

Ecology & savings from day one

• Less plastic: especially with a mains-fed cooler/filter you significantly reduce the need for bottled water.
• Fewer transports and carrying: practical convenience and a smaller footprint.
• Stable access to cold/hot water: supports better hydration at home & work.
• Energy efficiency: modern water coolers are designed for lower daily running costs.

Cooling Systems: Thermoelectric Cooling (PCB) vs Compressor (Freon)

Water coolers operate with two different cooling systems, each with its own advantages and disadvantages:

1. Thermoelectric Cooling (Thermoelectric / Peltier)

Thermoelectric cooling is based on Peltier technology, where an electronic module transfers heat away from the water without moving parts or freon.

✅ Advantages:

• Quiet operation – Ideal for offices and homes.
• Compact size – Suitable for countertop and small coolers.
• Eco-friendly – No refrigerant gases.
• Lower cost – More affordable to purchase.

❌ Disadvantages:

• Lower performance – Cools water 10–15°C below ambient temperature.
• Slow recovery – Needs time after use.
• Not suitable for high consumption – Doesn’t cover heavy demand.
• Affected by heat – Performance drops in summer.

Ideal for: Home use, small offices, 1–3 people.

2. Compressor Cooling (Compressor with Freon)

Compressor cooling works like a fridge or air conditioner: the compressor compresses the refrigerant (freon), which cools the water to much lower temperatures.

✅ Advantages:

• High performance – Chills water to 4°C to 10°C.
• Fast recovery – Continuous cold water, even with higher consumption.
• Stable performance – Not affected by ambient temperature.
• Ideal for professional use – For spaces with many people.
• Long-term durability – With proper maintenance, lasts for years.

❌ Disadvantages:

• Noise – Produces sound during operation (like a refrigerator).
• Larger size – Needs more space.
• Higher cost – More expensive than thermoelectric cooling.
• Refrigerant – Modern options are more eco-friendly, but the technology uses refrigerant.

Ideal for: Offices, companies, gyms, higher consumption.
