Overview of what the channel tested

The video re-runs and properly explains an earlier measurement-based comparison of cooking time and electricity cost for:

  • Induction cooker
  • Infrared heater
  • A generic heater (2000 W type element)
  • Infrared using two utensil types: “normal raised vessel” vs “flat vessel”

They keep the heat target consistent by using 2.25 liters of water (2250 ml) across tests. Different utensils are used for induction vs infrared to highlight efficiency differences and power loss.

Method / measurement approach (key points)

  • Earlier confusion is addressed: they measured power consumption, but didn’t clearly show the water heating/temperature timeline, so viewers were confused.
  • A power meter records:
    • Energy consumed (units)
    • Minutes run
    • Wattage/load fluctuations
  • Timer handling note: the meter’s timer may start even with very small power draw (they mention “one watt”), so for accurate time measurement they prefer a stopwatch on a mobile.
  • Infrared meter setup: the infrared plug is described as 16A, so they used a meter inline via the 16A socket.

Note: Load fluctuates on the infrared heater, which affects both time and measured energy.

Test 1: Induction cooker (with induction vessel)

Target: heat water to ~90°C, then note time to boiling.

  • Power setting used: 1400 W
    • Reason: the induction model “doesn’t go to 1800 W max,” so they run at maximum available 1400 W.
  • Temperature progression:
    • ~90°C reached in 14 min 20 sec
    • Boiling starts ~20 min
  • Electricity consumption (units):
    • To 90°C: 0.24 units
    • Total to boiling: 0.34 units
  • Cost conversion: assuming ₹6 per unit
    • 90°C cost: 0.24 × 6 = ₹1.44
    • Boiling cost: 0.34 × 6 = ₹2.4

Test 2: 2000 W heater (element heater)

  • Quantity: same 2.25 L
  • Power setting: 2000 W
  • Temperature progression:
    • 90°C reached in 11 min 40 sec
    • Boiling well in 13 min 30 sec
  • Units:
    • To 90°C: 0.38 units
    • To boiling: 0.43 units
  • Cost (₹6/unit):
    • 90°C: 0.38 × 6 = ₹2.28
    • Boiling: 0.43 × 6 = ₹2.58

Test 3: Infrared heater with “normal raised vessel” (inefficient contact)

They emphasize that infrared transfer depends strongly on vessel surface contact. With a raised vessel, only the center portion touches, which wastes heat.

  • Power setting: 2000 W
    • Actual load fluctuates (they mention values around ~1300 W and 1400 W).
  • Temperature progression:
    • ~5 min → 45°C
    • ~15 min → 86°C
    • 90°C reached in ~16 min 45 sec
    • Boiling not proper even by 24 min 30 sec
    • Later shows about 95°C
  • Units:
    • To 90°C (16:45): 0.40 units
    • By ~24:30: approx 0.58 units (highest so far)
  • Cost (₹6/unit):
    • 90°C cost: 0.40 × 6 = ₹2.4
    • By ~boiling attempt: 0.58 × 6 = ₹3.48

Core conclusion: Raised/poor-contact vessels on infrared increase both time and electricity usage.

Test 4: Infrared heater with “flat utensil” (better surface contact)

They simulate a flat utensil by using an induction cooker vessel on the infrared cooktop, arguing that infrared “supports all utensils,” and a flat base improves contact.

  • Power setting: 2000 W
    • Load around ~1644 W
  • Temperature progression:
    • 90°C reached in 8 min 28 sec
    • Boiled well by 10 min 25 sec (water reaches ~98°C)
  • Units (reported as lowest):
    • To 90°C: 0.25 units
    • To boiling: 0.30 units
  • Cost (₹6/unit):
    • 90°C: 0.25 × 6 = ₹1.5
    • Boiling: 0.30 × 6 = ₹1.80

Final comparison (time + electricity cost)

Using ₹6/unit conversion:

To reach ~90°C

  • Induction: ~14 min 20 sec, ~₹1.44, 0.24 units
  • 2000 W heater: ~11 min 40 sec, ~₹2.28, 0.38 units
  • Infrared (normal raised vessel): ~16 min 45 sec, ~₹2.4, 0.40 units
  • Infrared (flat utensil): ~8 min 28 sec, ~₹1.5, 0.25 units

To boil water

  • Induction: ~20 min, ~₹2.4, 0.34 units
  • 2000 W heater: ~13 min 30 sec, ~₹2.58, 0.43 units
  • Infrared (normal raised vessel): ~24 min 30 sec, ~₹3.48, 0.58 units
    • And not truly boiling properly
  • Infrared (flat utensil): ~10 min 25 sec, ~₹1.80, 0.30 units

Main takeaways / “what you should learn”

  1. Infrared performance depends heavily on vessel contact. A raised / imperfect-contact vessel wastes energy and increases both time and electricity consumption.

  2. Best cost/time in these tests: Infrared + flat utensil and induction are most efficient around ~90°C and boiling.

  3. Infrared with normal raised vessel is worst: It shows the highest units and even struggles to boil quickly.

  4. Induction caveat: The induction model used may not reach full rated power (they suggest it may not go to 1800 W max). Faster induction models (2100–2200 W) could perform better.
