Uhm, currently I'm using an electric boiler to boil water. My housemate says that it is more economical to boil it using gas. I doubt so because it won't make much difference.

So.. anybody here can enlighten me?

additional info: the boiler uses about 2000W and 1 gas tank costs about rm21.

Tolong

i smell butthurt lasis... am i doing it rikes

gas cheaper..but duno how to kira

I also fail in calculation. But,

- how long to boil water in kettle on gas stove? 23 minutes on blue flame, not yellow flame.

- how long it takes on electric kettle?

- how many kettles can u boil on a single gas tank? Divide.

- How many kwh used for the same amount of kettles used to boil with electric? Divide.

- Take gas price per kettle, take electric price per kettle.

Aiyaaaaa dunno la.

electric kettle.
the heating element is right inside the kettle so the water can be boiled faster.
for gas, the fire need to overcome the heat capacity of the metal before it can heat up the water inside more energy wasted.

even if u guys insists on gas but i got one good question for you.
1. Which one boils faster?
2. Which one is more convenient to get?
3. Which one is safer to use?

Think and you will know =)

aiyoh.... why susah-susah wan to calculate for 3 days for which 1 cheaper?.. if even cheaper by .5 cents i would rather get more convenient for that price... use the electric kettle...period... use gas after u fall asleep and burn the house down....

and you dont use 1 tank gas to boil 1 liter water right?

if parents pay electric bill you use electric lar

i buy gas rm23 per tong, u bought rm21 onli.so chip

GAS boils faster. Takes less than 3 min to start boiling and bingo.

I've done the calculations.

My water boiler consumes 2000W and can get the job done in 10 minutes, therefore 2000W x (10/60)/1000=0.333kWh

it will be 0.333kWh x 0.218 = RM 0.0726

I use it 3 times per day throughout a month.

That means it is 0.0726 x 3 x 30=rm6.50

I have 5 person staying in this house. Therefore, I don't think it is wise to save on this considering safety issues.

The difference is negligible to be honest. Yeah you could save some after 5 years, but is it worth the effort? No imo

are you sure?
my mum hate to use the gas.
scared terbakar the whole house and can't boil if got wind blow.
Normally take about 10min ++.
You sure gas is cheap?

Electric is the safest and fastest.
How much can the electric cost?
