How much will the bill increase if you turn on the geyser for 1 hour every day? Know the full account

Use of geysers becomes common in winter, but this habit can also give a shock to the electricity bill at the end of the month. Most people do not know how much electricity is consumed by keeping the geyser on for just one hour every day and how much direct impact it has on the bill. If correct calculations are understood in time, expenses can be controlled to a great extent.

Why is the power rating of a geyser important?

Power consumption is assessed by the watt rating of the geyser. Generally, 1000 watt (1 kilowatt), 1500 watt and 2000 watt geysers are commonly used in the market. The higher the watt rating, the higher the power consumption.

How many units are spent in one hour?

Electricity consumption is measured in units, also called kilowatt-hours (kWh).

1000 watt (1 kW) geyser
Consumption in 1 hour = 1 unit

1500 watts (1.5 kW) geyser
Consumption in 1 hour = 1.5 units

2000 watt (2 kW) geyser
Consumption in 1 hour = 2 units

If you run the geyser on an average for 1 hour every day, then the consumption for a month (30 days) will be like this –

1000 watt: 30 units

1500 watts: 45 units

2000 watts: 60 units

How much will it affect the electricity bill?

Now let us assume that the average electricity rate in your area is Rs 6 to 8 per unit.

30 units × ₹7 = approximately ₹210

45 units × ₹7 = approximately ₹315

60 units × ₹7 = approximately ₹420

That means geyser alone can add Rs 200 to Rs 400 to your monthly bill. If more than one person in the house uses the geyser or the time increases, this amount can be even higher.

Why does consumption increase?

Old geysers, faulty thermostat and setting temperature higher than required increase power consumption. Many people keep the geyser on for a long time before taking bath, due to which the unit heats up faster.

How to save on expenses?

Experts recommend that the temperature of the geyser should not be more than 50–60 degrees Celsius. Turn on the geyser just before taking bath and turn it off as soon as you are done. Periodic servicing also reduces electricity consumption.

Only wisdom will save the budget

Geyser definitely provides convenience, but if used without proper calculation, this convenience can prove to be heavy on the pocket. With the right information and a little care, you can enjoy hot water in winter and also avoid shocks from electricity bills.
