Why Energy Efficiency Matters
Energy bills are climbing. Climate concerns are growing. In this environment, small choices—like how we boil our water—can have big impacts.
So the question stands: Are hot water dispensers more energy efficient than kettles?
Let’s break it down with real data, real savings, and a real solution.
Traditional Kettles: Familiar but Wasteful
Kettles are a kitchen essential—but are they efficient? Not exactly.
Power Usage
Most electric kettles operate at 3000 watts (3 kW). That’s a lot of energy just to heat water, especially if you're only making one cup.
The Overboil Problem
Surveys show over 67% of people overfill kettles, boiling more water than they need. This common habit translates to millions of kWh wasted annually.
Heating Time
To boil a single cup (180ml), a standard kettle takes approximately 2 minutes, using roughly 0.1 kWh of electricity per boil.
Meet Henotix: Smarter, Faster, More Efficient
At Henotix, we’re reinventing how homes heat water. Our 2000W instant hot water dispenser is purpose-built for speed and sustainability.
Power Efficiency
Operating at 2000 watts, Henotix still uses 33% less power than a kettle, while delivering performance that’s even faster.
Time to Heat
We heat one cup (180ml) in just 15 seconds, using only 0.0083 kWh of electricity—compared to 0.1 kWh used by kettles.
Daily & Annual Energy Savings: Real Numbers
Let’s look at everyday savings:
Per Cup
- Kettle: ~0.1 kWh per 180ml
- Henotix (2000W): ~0.0083 kWh
- Energy Saved Per Cup: ~0.0917 kWh
Personal Yearly Impact
- Daily Cups (avg. UK adult): 8
- Yearly Energy Saved: 0.0917 × 8 × 365 = 267.76 kWh
- Annual Savings (at £0.36/kWh): ≈ £96.39
That’s nearly £100 saved per year, just from boiling water smarter.
National Savings Potential
Let’s scale this up.
UK-Wide Stats
- 100 million cups heated per day
-
otal Potential Savings:
- 100,000,000 × 0.0917 kWh = 9.17 million kWh/day
- Equivalent to powering 3057 UK homes for a full year
