Regular cleaning and BLDC fans will also save electricity.

AC with Ceiling Fan: During the summer season, most people reduce the temperature of the air conditioner significantly to cool the house quickly. But the huge electricity bill at the end of the month often causes trouble. Interestingly, an easy solution to this problem may already be present in your room: a ceiling fan. Many people turn off the fan as soon as they turn on the AC, whereas running both together is considered a very effective way to increase cooling and save electricity.

The fan makes you feel cool, not the room.

Often people think that the fan reduces the temperature of the room but in reality it is not so. The main function of the fan is to transport air to your body. When air hits the skin, sweat dries quickly and body heat escapes. For this reason, a person may feel colder than the actual temperature by about 2 degrees Celsius.

This difference may sound small but it proves to be very important for comfortable sleep and better cooling on hot nights.

Why does the pressure on AC reduce?

The nature of cold air is to move downwards. This is the reason that sometimes the lower part of the room feels colder while the upper part remains relatively warm. In such a situation, the AC has to work harder to cool the entire room evenly.

When the ceiling fan runs, it mixes the cold and hot air present in the room and spreads it evenly. Due to this, uniform coolness is felt in the entire room and the thermostat of the AC quickly reaches the set temperature. As a result the compressor runs for less time and power consumption is reduced.

The real mathematics of electricity saving

Since the fan makes you feel extra cool, the temperature of the AC can be increased by a few degrees. For example, if you were earlier running the AC at 22°C, you can feel almost the same comfort by setting it at 24°C or 25°C with the fan on.

A normal AC can consume around 1000 to 2000 watts of power whereas most ceiling fans only consume between 15 to 70 watts. According to energy experts, every 1 degree increase in AC temperature can reduce cooling expenses by about 4 to 8 percent. Therefore, increasing the temperature by a few degrees can cause a significant difference in the electricity bill.

Understand the benefits according to an Indian family

Suppose your AC runs for 8 hours daily in summer and consumes an average of 1500 watts of electricity. According to this, about 12 units of electricity will be consumed per day. If the electricity rate is considered to be around Rs 8 per unit, then around Rs 96 will be spent daily on AC alone. This amount can reach approximately Rs 2880 in the entire month.

Now if you increase the temperature of AC by 3 degrees and also run a 50 watt ceiling fan, then the additional cost of the fan will be very less. On the other hand, power consumption of AC can be reduced by 12 to 24 percent.

In such a situation, it is possible to save hundreds of rupees by the end of the month. During a typical Indian summer of four months, this saving can be Rs 1200 to Rs 2400 or even more.

BLDC fan can save more

Nowadays, ceiling fans with BLDC technology available in the market consume very less electricity. These fans consume about 15 to 28 watts of power even at full speed, which is much less than the old fans. If you are thinking of buying a new fan, then the BLDC model can help in reducing your electricity bill further.

Pay special attention to these things

The fan only makes people feel cool, so if there is no one in the room, it should be switched off. A fan running in an empty room only consumes electricity and may also generate some heat due to the motor.

Apart from this, also ensure that in summer the ceiling fan is rotating in the right direction so that the air comes downwards and provides better cooling. Besides, regular cleaning of AC filter and fan blades is also necessary. When dust accumulates, both the devices have to work harder, which increases power consumption.

This item consumes the most electricity in the house, if you know then you will be able to save

Increasing electricity bill has become a common problem in almost every household today. Many times people wonder why the bill has increased even though they did not use much. In fact, there are some appliances present in the house which silently consume the most electricity. If these are identified and used properly, then one can get relief from huge bills coming every month. In such a situation, let us tell you today which items consume the most electricity in the house and if you know about them, then how will you be able to save.

AC is the biggest reason for electricity bill

The most electricity consuming appliance in the house is air conditioner i.e. AC. If the AC is operated for 8 to 10 hours daily, it alone can consume about 40 percent of the total electricity. Especially in summer, excessive consumption of AC directly increases the bill.

Geyser is also not behind in electricity consumption

Geysers become the second most electricity consuming thing in winter. If the water is too cold and the geyser is kept on for a long time, the unit heats up faster and older models consume more electricity. Therefore, running the geyser for longer than necessary can prove costly on the bill.

Fridge running 24 hours increases expenses

The refrigerator runs day and night. Therefore its power consumption remains constant. If the fridge is old or has low star rating then it can increase the electricity bill by 10 to 15 percent every month. At the same time, frequent opening of the fridge and lack of proper ventilation also causes increase in consumption.

hidden effect of washing machine

The effect of washing machine is not directly visible on the electricity bill, but daily use, hot water mode and maximum use of dryer increase the electricity bill. At the same time, electricity consumption can be reduced by washing clothes in eco or normal mode.

Old equipment becomes the biggest problem

10 to 15 year old refrigerators, old bulbs and tube lights are big consumers of electricity. It consumes many times more electricity than the new technology. Apart from this, TV and setup box keep on consuming electricity even in stand by mode, which is often ignored.

easy way to save electricity

If you want to reduce the electricity bill, then first of all it is important to pay attention to the appliances that consume more electricity. Keep appliances switched off when not needed, avoid standby mode and use LEDs instead of old bulbs or tube lights. Also, to save electricity, it is important to understand which appliance in the house is consuming how much electricity.
