KUALA LUMPUR (Bernama): Water purifiers that have heating and cooling functions are one of the main reasons for high electricity bills, says Selangor TNB.
Its retail chief, Ismail Lathifi Teh, said electrical appliances with cooling systems such as refrigerators, air conditioners and water purifiers, consume a lot of electricity to maintain a constant temperature.
"During hot weather, machines with compressors will use more energy to maintain a steady temperature.
"So if we keep opening the refrigerator door or take chilled water from the water purifier in our homes, more electrical energy consumption is required to maintain the cold temperature," he said.
He said for household water purifiers, water flows into the tank to replace any cold water drawn, and the compressor would running to cool the water.
"As more water is filled, the compressor cooling system will continue to operate, resulting in more electricity consumption," he said.
To reduce power consumption of air conditioners, Ismail Lathifi advised consumers to use the timer function and set the temperature at 24 to 26°C.
"Consumers are encouraged to use the timer so that the air conditioner switches off early in the morning or from 2am onwards when the room has cooled down. Thereafter, switch on the fan to maintain the cool temperature," he said.
He also urged consumers to service their air conditioner units regularly so it can operate efficiently and economically.
"I have received complaints from consumers that they do not use air conditioners but their electricity bill has increased substantially. They forget that other electrical appliances also consume electricity," he added. – Bernama
