an electric geyser takes 2000 watt 2 to 20 volts
Answers
so, per run: 3Kw x 2 mins. Per month: 3 kw x 60 mins or 1 hr = 3 kwh.
1 khw costs around 4 Rs, hence Rs 12 monthly (run once daily)
2) 10 litre storage, 2kw, takes 10 mins:
so, per run, 2kw x 10 mins. Per month: 2 kw x 300 mins or 5 hours = 10 kwh.
1 Kwh = around 4 Rs, hence monthly cost run once daily = Rs. 40.
If run 'a' times per day, cost will be 'a' x above estimates. So, run 5-6 times daily, instant 1L thingie will cost 12 x 5 = 60 Rs. per month.
However, the stores are putting up a different cost calculation which I'm not scientifically capable of understanding. They are showing me charts similar to the one at the bottom of this page: Gas Geyser -
At least 2 of them are telling me that electric geysers bill upto 5-6 k a year to run for 2-3 people.:huh:
I have taken from this forum that gas geysers for 3 people need 1 LPG cylinder every 40 - 45 days. So roughly, cost per year would be 9 LPG cylinders @ Rs, 350 = Rs. 3200ish.
Answer:
:) plz thank me
Explanation:
1) small 1 litre instant, 3kw, takes 2 mins.
so, per run: 3Kw x 2 mins. Per month: 3 kw x 60 mins or 1 hr = 3 kwh.
1 khw costs around 4 Rs, hence Rs 12 monthly (run once daily)
2) 10 litre storage, 2kw, takes 10 mins:
so, per run, 2kw x 10 mins. Per month: 2 kw x 300 mins or 5 hours = 10 kwh.
1 Kwh = around 4 Rs, hence monthly cost run once daily = Rs. 40.
If run 'a' times per day, cost will be 'a' x above estimates. So, run 5-6 times daily, instant 1L thingie will cost 12 x 5 = 60 Rs. per month.
