Room Cooler

Q1) How can I choose an energy efficient room cooler?

Here are some tips for choosing an energy efficient room cooler:

  • Decide on the category and feature you want. For details, please refer to the table below.
     
  • Choose the right cooling capacity to suit the size of your room. To avoid excessive electricity consumption, room cooler with larger capacity is not a must.
     
  • Use the energy label to help you select a better energy-efficient model.
     
  • Choose a model with better efficiency grading.
Category Description
1 A window type room cooler with cooling function only
2 A window type room cooler with both cooling and heating functions
3 A spilt type room cooler with cooling function only
4 A split type room cooler with both cooling and heating functions

Washing Machines

Q1) How can I choose an energy efficient washing machine?

Here are some reminders for choosing an energy efficient washing machine:

  • Decide on the category and feature you want. For details, please refer to the table of washing machine category. Don't buy a machine of size exceeding your need as it will consume more energy and water.
  • Choose a machine with a cold wash and cold rinse option.
     
  • Choose a model with half-load function. This allows you to save water and energy for small loads.
     
  • Use the energy label to help you select a better energy-efficient model.
     
  • Choose a model with better efficiency grading.

Rice cookers

Q1) How can energy efficient rice cookers save energy?

An energy efficient rice cooker saves energy in the following ways:

  • An energy efficient rice cooker has higher heat efficiency.
     
  • Heat efficiency measures the proportion of electrical energy that is consumed in heating during rice cooking.
     
  • The minimum heat efficiency requirement of a rice cooker ranges from 85% to 89%, depending on the size. The requirement for a model of larger size is comparatively higher.

Household electric storage water heater

Q1) How can energy efficient household electric storage water heater save energy?

An energy efficient household electric storage water heater saves energy in the following ways:

  • After reaching the desired hot water temperature, a general electric storage water heater still consumes electrical energy continuously in order to prevent such water temperature from dropping significantly due to heat loss when the water heater is at standby condition.
     
  • An energy-efficient household electric storage water heater designed with optimum performance and excellent insulation can reduce electrical energy consumption at standby condition.
     
Category Description
1 A small-size unvented electric storage water heaters for domestic use with a rated capacity not exceeding 50 litres
2 A small-size open outlet electric storage water heaters for domestic use with a rated capacity not exceeding 50 litres
3 A horizontal tank type electric storage water heaters for domestic use with a rated capacity not exceeding 50 litres and up to 300 litres
4 A vertical tank type electric storage water heaters for domestic use with a rated capacity not exceeding 50 litres and up to 300 litres

Dehumidifier

Q1) How can I choose an energy efficient dehumidifier?

Here are some reminders for choosing an energy efficient dehumidifier:

  • Choose the right dehumidifying capacity to suit the size of your room. To avoid excessive electricity consumption, dehumidifier with a larger capacity is not a must.
     
  • Choose a model with energy label.
     
  • Choose a better energy-efficient dehumidifier. Energy Factor is measured according to the amount of water removed in litres per kilowatt-hour (kWh) of energy consumed. Dehumidifiers with energy factor equal to or greater than 1.2 L/kWh save more energy. For details, please refer to the table below.
     
  • Choose a dehumidifier equipped with automatic control of dehumidifying function.
     
Product capacity (L/day) Energy factor under test conditions (L/kWh)
L/day ≤ 10 ≤ 1.2
10 L/day ≤ 25 ≤ 1.3
25 L/day ≤ 35 ≤ 1.5

Television

Q1) How to achieve energy-efficient use of television?

Here are some tips for using television in a energy-efficient way:

  • Avoid placing any TV or AV product in humid, dusty or hot environment or under direct sunlight.
     
  • Disconnect power supply if a TV is not to be used for a prolonged period of time. Avoid switching it off merely with the remote control.
     
  • Place a TV on a flat and firm surface to prevent it from falling down and causing injury.
