Energy Saving Tips

Electricity is a resource under pressure.

Please do your bit to save electricity today by following these simple tips:


Dishwasher energy consumption can be reduced by turning off the dishwasher after the final rinse and before the drying cycle. The clean dishes can then be wiped with a dry cloth.

Fill the dishwasher completely before operating. Partial loads waste electricity and water.

Short wash cycles, rinse-only cycles, mid-cycle turn-off, and other features are designed for energy conservation as well as convenience.

Connect your dishwasher to COLD water supply unless otherwise directed.

Normally only one wash and one final rinse cycle requires hot water which is heated by an element in the dishwasher.

The dishwasher filters must be kept clear of debris. A blocked filter reduces efficiency and wastes energy.

Proper loading is important for the dishwasher to work efficiently.


Choose a refrigerator of a size based on the needs of your family – a refrigerator operates at peak efficiency when filled.

Do not overload your fridge, excessive products in your fridge will lower the quality of the food and use more electricity – as much as 10-20% more for each extra product.

Do not set freezing temperatures lower than necessary; it wastes as much electricity as excessive heat.

Thick frost on chilling panels reduces cooling ability. If you do not have a frost-free model, defrost your refrigerator when frost is between 0,6 to 1,3 cm thick.

Do not open your refrigerator door needlessly. By getting into the habit of removing and replacing several articles at once, you will reduce the loss of cold air.

Let hot foods cool down before placing them in the refrigerator. (To prevent bacterial growth allow about 20 minutes standing time).

Be sure the seal around your refrigerator door is intact. (Close the door on a piece of paper: if you can pull the paper out easily, the seal should be replaced).

Remove all heavy wrapping from food before storing it in the refrigerator.

Cover all liquids stored in the refrigerator (especially frost-free models).

Foods should be placed slightly apart on refrigerator shelves to allow the cooling air to circulate.

Exposed condenser coils/panels (usually at the back of the unit) MUST be kept clean and dust free. When cleaning you must be careful not to damage the panels.

Do not place the refrigerator near the stove or against an uninsulated wall that faces the sun.

Allow adequate space around the refrigerator for free air circulation. The air carries heat away from the fridge – if air cannot circulate, the fridge cannot work properly.

Switch on the energy saving switch, if one is fitted to the refrigerator.
Switch off, empty or clean your fridge, when taking an extended holiday.


Freezers and refrigerators operate most efficiently when filled to the capacity recommended by the manufacturers.

Never forget that only one-tenth of a freezer’s capacity should be used for freezing of fresh food at any one time. The freezer must work harder to remove heat, and uses more power. Example, 28 litres (one cubic foot) will store 12,5 to 15 kg (25-30 lbs.) of frozen food and will freeze about 1,5 kg (3 lbs.) of fresh food at a time.

Food to be frozen should be placed in contact with those parts of the freezer that contain the refrigerant tubes, usually the sides of chest models.

Defrosting of chest type freezers should be done once or twice a year. For upright models, defrosting should be done two or three times a year. NEVER allow frost build up to exceed 0,6 to 1,3 cm.

By keeping a list of the location of foods in the freezers, the freezer can be kept open for a minimum of time, preventing the loss of cold air.

The freezer should be kept as full as possible to prevent heavy icing.

On all models keep condenser panels at the rear of the freezer clean and dust free for maximum efficiency and conservation of energy.

A second freezer should only be operated when necessary.

In a single door unit, it is essential that the separate freezer compartment has its own door intact. Otherwise the unit will tend to operate the whole of the refrigerator as a freezer – this can be expensive.

Electric stove

Use cooking utensils with flat bottoms and tight fittings covers.

Be sure pots and pans completely cover the stove plates.

Take advantage of the heat sensing control for stove plates. It allows the stove plate to cut of the electricity supply occasionally while still cooking. It does not affect the food, only your bill.

Use a pressure cooker to conserve energy when cooking foods that take a long time, such as pot roasts, stews and steamed puddings.

Do not overcook foods, especially vegetables. Overcooking destroys essential nutrients.

For full efficiency from radiant stove plates the stove plate reflectors (underneath the stove plates) should always be kept clean.

Bring foods to the boil quickly on the “high” setting, then turn the heat down to simmer to finish cooking.

Do not use the grilling compartment to make toast – it is very expensive.

Do not use the oven to heat the kitchen – it is very expensive and far less efficient than a heater

Keep oven doors completely closed until food is cooked. Every time the door is opened, the oven temperature drops, and the heat must be replaced.

Use the oven to prepare an entire meal – main course, vegetables and dessert.

Remember to plan meals that cook in the oven at the same temperature.

Allow free circulation of heat within the oven. Place pans and containers so that they do not touch each other, or the sides of the oven.

To keep food warm place in a 66˚C (150˚F) or 82˚C (180˚F) oven. Do not leave it too long or your meal will be very dry.

When buying a new stove, choose one with a convection oven. This type of oven uses less energy than conventional ovens and cooking time is substantially reduced.

Microwave ovens

Defrost your food in the refrigerator instead of the microwave oven: it is more economical.

Use your microwave oven to cook small to medium quantities of food. To cook larger portions of meat, it is better to use a conventional oven.

Some microwaves do not heat up foods evenly. Wrap foods in plastic to hold in the steam, this will help to give even heating. Be very careful not to cover the foods too well, steam can burn you badly when you open the packet, so leave a flap open for the steam to escape.

Cooking time is an important factor when determining energy efficiency levels.

Compare cooking times when you cook the same food in the microwave, in the standard oven, on stove top elements or in a pressure cooker. You will easily see which method of cooking is more efficient depending on quantity, volume and food types.

Follow the manufacturer’s instructions to ensure that food is cooked correctly. Keep in mind that microwave recipe books give the cooking times required by the appliance used by the authors. Adjust cooking times to suit your micro- wave rating.

Never turn your microwave on when it is empty, you could damage it.

Keep the edges of your microwave door and its hinges clean. To wash the inside of your oven, boil a cup of water in it and then wipe the sides with a damp cloth.

Small appliances

Using small kitchen appliances instead of the stove can save energy. Toasters, electric grills and skillets, slow cookers, electric coffee pots and bottle warmers usually require less energy than the stove when used correctly.

Use an electric kettle to boil water, not a sauce pan or a microwave.

When vacuuming, empty or replace the dust bag frequently.

A faulty appliance will not work efficiently and can waste energy. Repair or replace them promptly.


You will save energy, money and eye strain by lighting your home properly.

Follow these guidelines:

The wattage of a bulb is not a measure of the amount of light it gives, but rather the energy it uses. For instance, a 100 watt bulb gives 50% more light than four 25 watt bulbs. (Image on Slide: Use Electricity Wisely – in the Bedroom)
Fluorescent lamps give five times the light and last up to 10 times as long as ordinary bulbs.
Fluorescent lighting is more economical – Watt for Watt than incandescent bulbs. They use less energy and can last about 10 times longer. (Image on Slide: Use Electricity Wisely – In the Bedroom)
Never confine lighting to one part of the room. Avoid heavy contrast by using lamp shades that direct light both up and down.
Try not to install multiple lights (lamps or lighting fixtures) on a single switch. Above all, turn lights off whenever possible because, they use electricity while they burn.
Clean your lamps and bulbs regularly, because dirt decreases the amount of light given out.
Dimming switches allow you to regulate the light level and reduce electricity consumption to some extent.
Use lampshades with a white liner. Liners should be sufficiently dense to hide the bulb but should transmit soft, even light.
Use low energy lamps for exterior lighting.

Air conditioning

Air conditioning circulates the air and makes your home more comfortable. It maintains the temperature at a suitable level, dehumidifies, and removes dust and particles from the air, Here are some ways to increase its efficiency:

Clean and inspect filter screens regularly. This will keep electricity consumption at its best and eliminate dust and pollen from conditioned air.
Use light coloured curtains to reflect sun and heat outward.
Set the air conditioning unit to re-circulate cool air instead of drawing in warmer outside air.
Protect the outdoor cooling units from the sun. Place them on the south or shady side of your house.
Be sure your television, radio and stereo are off when no one is watching or listening.
Generally, you should turn your heating/cooling system off when the space in unoccupied. You can use a time-clock to turn them on prior to occupancy again if you like. Do not heat storage and unoccupied areas, like the basement or garage.

Washing machine

Buy a washing machine, which offers a variety of water temperature settings.

A front loading washing machine uses less water and costs less to operate even though the purchase price may be higher than a top loader.

Use warm and cold water setting as much as possible in order to cut down on energy needed to heat the water.

Take advantage of special features on your washer that can save money. For example, soak cycles remove stubborn stains in one wash cycle.

The automatic washing machine uses the same amount of electricity for a full load as it consumes for a single item. Save dirty clothes until a full load has accumulated.

Never overload your automatic washing machine. Overloading will reduce the cleaning action. (Varying the size of garments in a full load improves the cleaning action by allowing free circulation).

Tumble dryer

Clean the lint filter on the dryer after each operation to maintain full air flow and to maximise the drying efficiency.

Dryers equipped with an electronic humidity control are the most efficient because they automatically shut off the drying cycle when the clothes are dry.

Other models are equipped with electric timers which, allow you to select the length of the drying cycle. Here it is important not to overestimate the length of the drying cycle.

A permanent press cycle with a “cool-down” period saves energy and dries efficiently.

Compact dryers are economical provided that you only have small amounts of clothes to dry. Never overload a tumble dryer but avoid under-loading as well.

Use correct temperature settings to minimise the amount of electricity consumed.

Over-dried clothes feel harsh and waste energy. Experiment to find the right setting. Some natural materials such as cotton and wool should retain some moisture to avoid wrinkling.

Clothes should never be placed in the tumble dryer dripping with water. They should have as much moisture removed beforehand and they should never be folded before being placed in the dryer.

Dry clothes in consecutive loads where possible. The dryer will be warm already and will save on initial energy consumption.

On sunny days take advantage of good weather and dry your clothes outside.


An iron consumes as much energy as ten 100 watt light bulbs. Several steps can be taken to increase ironing efficiency.

Iron low temperature fabrics first to reduce warm up time.

Iron large batches of clothing at one time to avoid wasting energy reheating the iron several times.

Switch your iron off before you are finished and complete the ironing on stored energy.

Prevent scorching and wasting energy by not over heating the iron.

Use only distilled water in steam irons.

Be sure to turn your iron off if you are interrupted whilst ironing.

Use the permanent press feature on your washer and dryer if it is available.

By removing clothing promptly from the dryer and folding them carefully, many items will require no ironing, or just a quick press.


Infrared heaters are more electricity efficient than other space heating systems.

These types of heaters can be used both for spot heating and area heating. They transfer energy directly by radiation, creating heat and comfort instantly without the use of air-circulation fans. An infrared heater will warm the people in the room rather than the space. Infra-red heaters often use metal-sheeted infrared radiation elements, reflector lamps or quartz tubes.

The oil filled heater is the safest type of heater for the bedroom. A thermostat control switches the unit on and off as required, but to save energy, only use on the lowest comfortable setting.

Electric blankets consume little electricity. However, the correct method of use is to switch them on to the highest setting and warm the bed just before climbing in – then switch them off.

Close doors and windows when using a heater.


In parts of South Africa, during winter, the heating of rooms is one of the largest sources of electricity consumption in a home. Improving a home’s thermal insulation can save hundreds of Rands a year in space heating costs and improve the home’s comfort.

Insulate The Ceiling:
Insulating the ceiling helps make a home a comfortable electricity efficient place. As much as 50% of heat losses in a house can be attributed to a lack of ceilings and ceiling insulation. If a home’s ceiling is well insulated, heating and cooling expenses can be kept low. The effectiveness of ceiling insulation depends on the type of material from which it is made, its thickness and its density.

Ceiling insulation in SA varies from fibreglass insulation to a type of insulation prepared from a mixture of paper and other materials. The latter is blown into the ceiling, sealing the total roof area. Any of the methods are equally effective and the supplier of these insulation’s will be able to offer reliable information about ceiling insulation.

Seal Air Gaps In The Home:

The flow of air into and out of a home occurs inadvertently as infiltration / exfiltration and deliberately as ventilation. Air leakage into and out of the home is one of the contributors to high heating and cooling costs. Air infiltrating a house through leaks must be heated in winter and cooled in summer and this represents an additional load on the household’s electricity consumption. This additional load can account for as much as 20% of heating and cooling costs. Air leakage also permits dust, noise, fumes and moisture to enter a home.

Air leakage can occur wherever different materials or parts of the house meet. Caulking and weather-stripping are the ideal methods for closing the loopholes in your home through which heat escapes. Caulking simply means sealing cracks and holes in areas where air leakage can occur. Inexpensive and easy to apply, caulking requires just a few tools.

Weather-stripping is effectiveness at eliminating air leakage when it fits tightly against closed windows and doors. Many types of weather stripping are available, including foam rubber, felt, flexible vinyl and spring metal or plastic tension strips.

Make The Most Use Of The Home’s Thermal Mass:

Thermal mass is a term used to describe any material that absorbs and releases significant amounts of heat when a temperature difference occurs between it and the surrounding air. Concrete, brick and tile contribute to the thermal mass of a home.

Thermal mass can be taken advantage of to substantially reduce the use of heating and cooling appliances. As the air in a house cools and falls below the temperature of the thermal mass, the thermal mass slowly releases its stored heat, keeping the home warm for longer periods. This process of absorbing and releasing heat helps your home maintain a comfortable temperatures range. The value of thermal mass increases when it is exposed to room air, rather than covered by materials that hinder its heat absorbing and releasing effects. For example, a concrete floor covered by vinyl performs much better than a floor covered by carpeting.


In order to ensure that cold air outside the geyser does not increase the heat lost by the water inside, installing a geyser blanket can be very effective. A geyser blanket may seem like a costly expense, but it will probably be once-off and the pay-back in electricity efficiency and electricity savings make it a good investment. It should take less than an hour to install a geyser blanket and over twenty years it may save you thousands of Rands in electricity bills.

To optimise electricity efficiency, geysers should be located as close as possible to the points where hot water is being used.

Insulated hot water pipes maintain their temperature at constant levels and prevent heat loss. Pay special attention to the insulation of the first 1.5 to two meters of hot water pipes nearest the geyser. Water pipes can be insulated with ceiling insulation material, or through the use of pipe insulators that wrap around the pipes. This can save thousands of rands in heating costs over twenty years.

Eskom Guidelines for Installation of solar geysers

Water heating tips

It is likely that a home’s single largest electricity expense is water heating. This typically accounts for about 30% to 40% of the electricity account.

By taking a shower instead of a bath you can save hot water.

Normally, you use less hot water for a shower than a bath. In a bath 12 cm of hot water represents half the content of a 3000 Watt geyser, about 4 kWh of electricity is needed to heat it.

Get the family into the habit of plugging the water basin when washing or shaving. Allowing hot water to pour out of the taps and down the drain is wasteful.

Do not set the thermostat too high. A setting of 50-60˚C is recommended.

Food preparation and storage efficiency

A lot of the energy in your home is used in preparing and storing food. The following tips will help you to conserve energy while meeting your daily food-related needs.

Cook your food at the highest possible volume while still retaining the basic nutritional and health requirements.

Cook at a longer, lower temperature as opposed to a higher, shorter one. Slow cooking retains more of the nutrients in food and transfers less heat to the air around it – so you lose less heat energy and save more money in the long run.

Follow the manufacturer’s strict guidelines while heating and pre-heating your cooking equipment.

Heat your equipment only to the highest temperature needed – do not heat higher to pre-heat quicker or cook food faster, it will only waste energy.

Do not turn every appliance on in the morning out of habit. Turn them on only when they are needed and going to be used.

Draw up a cooking schedule. In knowing what foods need the same cooking temperature in advance, you can do them at the same time. Fill your oven to capacity and save on time and electricity.

Learn how to use your oven’s thermostat and timer. You can avoid continuous opening of your oven door while your food is cooking and thereby conserve the heat that is lost.

Warming drawers and plates are not cooking appliances. Excessive heat will dry out food so use them only as intended.

Keep your cooking equipment clean; it will last longer and use less electricity if well maintained.

Swimming pool

For houses with swimming pools, the swimming pool filter pump is likely to be amongst the largest consumers of electricity, possibly accounting for 20% of the home’s electricity consumption.

Reduce The Pool Pump Operating Time. Reducing the swimming pool filter pump operating time can save significant amounts of electricity. The pool pump operating time can be reduced by resetting the pump control clock to activate the pump for only those necessary for keeping the pool clean.

Covering your pool when it is not in use will reduce its water losses. A cover will also ensure that the pool need not be cleaned as frequently and the pool pump can be operated less often, for example 10% of the time.

The pool’s filter should be cleaned as recommended by the manufacturer to obtain maximum efficiency. This will enable you to operate the pump for shorter periods. Also use a wall brush and leaf skimmer regularly and remove foreign materials from the pool’s strainer baskets.

In general, your pool manufacturer should be in a good position to advise you on how to optimise your swimming pool’s electricity efficiency and should be consulted.

Check with the supplier of the swimming pool to establish the correct operation of the filter. Operating the filter longer than necessary can be very expensive, because it wastes electricity.

Power tools

Practically all portable tools are very efficient users of electricity because they are driven by electric motors which are very efficient.

Trigger switches ensure that the unit is only used when needed; but don’t overload the tool.

A faulty appliance will not work properly and can waste electricity. Repair or replace promptly.
