Tank Vs Tankless Water Purifier: Top 5 Reasons to Pick Tankless

This article compares Tank Vs Tankless water purifier. So, water purifier that uses ambient, cold and hot water tanks are very common. Recently there has been a surge of tankless water purifiers that is half the size of the traditional bulky water purifiers.

Below are points of comparison of what makes a tankless type water purifier unique and space saving as compared to one that uses tank.

For this example, we are comparing a non-branded tank water purifier and SK Magic’s JIKSOO Hyper.

As shown, cold and hot tanks and the cold compressor takes up a bulk the space for traditional water purifier designs.

1) Tankless is smaller and lighter: Large water tanks makes traditional water purifier bulky

Large water capacity simply means a bigger and heavier water purifier. This maybe unsightly for your kitchen space as you don’t want to waste space unnecessarily.

As in the pictures showed, it takes up most of the space in the water purifier. Cold compressor also takes up space and makes it heavy.

If it’s an R.O type filter, it will take a longer time to fill up the water tank as compared to Ultrafiltration or Nanotech membrane filters. Due to how fine the pores are for a reverse osmosis filter, water moves much slower.

When you need to clean the kitchen countertop, a tankless model is a lot more easier to move than a tank type.

2) Electric Saving: Hot water tanks uses more electricity as compared to tankless type.

The hot water tank requires heating around the clock, just to keep it constantly warm / hot. This obviously increases the electricity cost. It uses 300W to 500W depending on tank capacity.

Where else for a tankless purifier, it uses instant heating to heat the water before dispensing. While it uses 2400 watt, it ONLY uses it when water needs to be heated. So comparing both tank and tankless, the tank uses more electricity. Most hot tank electricity is wasted throughout the night as it is not in use, just to keep water hot.

What about eco saving mode for tank types? While it does help to save power, there’s a design flaw. It’s designed to be sensitive to light. It will cut electricity usage when it’s dark. If your kitchen is facing away from sun light,  it will depend on your home lighting in order to signal the water purifier to heat and cool again. More electricity will be used in other words.

A potential downside is that in the morning you will have to wait for the purifier to cool and heat sufficiently before dispensing.

The sensitivity of the eco sensor may vary between models.

3) No Reboil: No reboiling water for tankless

Some maybe concern about water constantly being reheated again and again. In this case, a tankless water purifier would suit very well since water is instantly heated only once before dispensing.

Water tank type purifiers with it’s hot and cold tank do take up a lot of kitchen pantry / countertop space.

Where as the JIKSOO tankless purifier will save up plenty of space both in width and height. Much suited for the modern looking kitchen design.

4) Space Saving: Minimalism with tankless design

It’s obvious that a tankless design would give a better minimalist look for a kitchen countertop, rather than bulky designs. Tankless also gives the option to place on a kitchen island due to it’s compact size.

The tankless design is as wide as pen’s length!

5) Hygiene: No water tanks means 99% bacteria free

There are two places in a water purifier that is exposed to bacterial growth: the water tank and water tab. A place exposed to water and moisture tends to breed bacteria.

The problem with tanks is that if it there is no scheduled maintenance, bacteria and algae tends to grow. We have serviced water tank purifiers that has not been cleaned before and it is usually filthy and unhygienic to consume. You can see algae and built-up micro sediments in it.

Plastic tanks are also the worst materials to store water as bacteria filled bio-films is more likely to grow and stick on the walls. That’s why plastic tanks needs to be cleaned every 2 months, which is too often.

For water tanks, it is important to use food grade, stainless steel as a water storage material. Steam sterilization and wiping of the tank is also required every 4 to 6 months.

Removing the water tank reduces the risk of bacteria or algae growth close to zero.

Tankless design is the way forward in water purifier technology. Do away with bulky designs and going minimalist.

The only benefit for using a water tank storage, is that it can accommodate for an office space or a cafe with a higher number of users. In this case, a stainless steel tank with UV light sterilizer will have the same clean standard as a tankless type.
