Boiling Water Tap vs Kettle: Which is More Cost Effective? – Mijnenergie.be Analysis

These devices are available in various versions. Models where the resistance comes into direct contact with the water usually consume the least.

It takes more than three minutes to boil one liter of water with a kettle with a capacity of 2,000 watts. At the current median price – via Mijnenergie.be – from 33.68 euro cents per kilowatt hour, it costs 35 euro cents to heat up water with the kettle.

In one cluster or separately: is it best to purchase natural gas and electricity from the same supplier? Or are you going for multiple energy players?

It Stove is a less efficient way to heat water. On the other hand, natural gas is cheaper than electricity.

According to the Dutch consumer program Radar, the amount of gas you use to boil water is 0.30 kilowatt hours. With a median natural gas price of 7.95 euro cents, it will cost you 2.4 euro cents to boil water. The difference in energy price between electricity and natural gas therefore outweighs efficiency.

The alternative consists in it induction cooker. Once again, the higher electricity price is a disadvantage. In that case, the cooking session will cost you 6.7 euro cents.

With a boiling water tap you immediately generate boiling water from the tap. The best-known brand on the market, Quooker, likes to show off its thermal insulation that increases efficiency and reduces energy costs. The total consumption of a Quooker reservoir includes a part to keep the water warm and a part to heat cold water.

To always have boiling water to hand, the Quooker uses 87.6 kilowatt hours or 29.50 euros per year. If you need an average of 10 liters of boiling water per day, the boiling water tap will use 423 kilowatt hours to heat the water and 87.6 kilowatt hours to keep it warm, according to the manufacturer. The total: 511 kilowatt hours per year or 172.11 euros.

The boiling water tap has the great advantage that you only boil the water that you actually need. In combination with solar panels, you can reduce the consumption bill, just like with induction or the kettle.
