top 10 energy saving tips aerolite

In this article, we will cover the top 10 energy saving tips for South African conditions. As we all know heavy energy consumption has an effect on our environment. So we will look at the top 10 energy saving tips in order of biggest savings. Homeowners that follow these steps can save as much as 50 if not more on energy saving.

Energy saving and the environment have been the most important discussion points in the last few years. As global warming is now wreaking havoc with our planet we all will be in a desperate situation soon.

Global warming, as well as pollution, are destroying the planet as we know it. Energy saving is at the top of the list for future generations.

Putting some of these tips in place if not all will be a huge energy saver for the future.

Top 10 Energy Saving Tips

  1. Solar Geyser Heating a rather expensive option is the Solar route, however, the results are good for energy saving.
  2. Heat pumps come in different size depending on family size. Far more affordable option with great energy savings. In fact, the energy saving is similar to those of solar heating.
  3. Double Glazed windows are a great energy saver as well.
  4. Solar film for summer benefits.
  5. Roof insulation products Isotherm Insulation or Aerolite Insulation reduce heat flow into the home.
  6. Wall insulation reduce heat flow through walls in summer.
  7. Floor Insulation if water levels are found below your home on new builds.
  8. LED lights save hugely on energy
  9. A gas stove is more economical than electric stoves.
  10. Door get the right door fitted and save on heat reduction.

Solar Heating

Solar heating for geysers or heat pumps will save a substantial amount of energy per year. In fact, it is estimated that if your energy bill is R 2ooo per month giving a total of R 24 000 per annum. Your energy saving will be about R 5800 per year. Now take into account that this energy saving will go on year after year.

When looking at this up front it does not seem as though the benefits are that great until you place this into a 10-year saving. This then changes the game totally as one must also consider rising energy cost as well. However just to simplify this let’s not take energy rising costs into account. The solar at a huge cost will save you around R69 000 per year.

Heat Pump Hot Water Solution

Heat pump 4.7 kilowatts this is ideal for a family of 6 and will cost a fraction of solar heating. The same applies let’s work on a family consuming R 2000 per month with an annual bill of R 24 000 per annum.  Your projected energy saving could be as much as R5400 per year.

The heat pump system at a fraction of the cost will save around R 64 800 per year. These figures are supplied by operators in their field of expertise so we rely on their input on accuracy. We are all aware that the standard geyser solution is expensive to run as they consume massive amounts of energy.

Double Glazed Windows

Most homes have old wooden framed window frames, unfortunately, these window types are not very energy efficient. Especially in winter when one needs heating in the home, having cold air entering through the windows that you think are closed will cost you a lot more in energy.

Most modern home today in South Africa must comply with the SANS legislation. Thicker glass for the windows or double glazed window. In fact, only 15% of your home can be glass unless you can achieve the recommend loss projection.

Double glazed windows are a massive energy saver per annum as it is expected that up to 25% of energy loss in the home will be through closed windows. Double glazed windows will reduce the summer heat gain as well as the winter heat loss.

Solar Window Tinting

Solar window tinting will reduce heat flow into the home substantially on the hot summer days. However, this option is not effective in winter when you need to conserve the warm air in the home. However heavy curtaining then would be able to act as an insulator against losing the warm air in the home.

Many homeowners do not like the idea of a tinted window glass, however, there is options with almost no tint that are very effective.

This is our field of expertise and we are experts on this subject. We do not believe in the blow in type paper dust insulation and will not install this. Especially in the Cape region where we get very strong winds as this tends to blow the insulation to different sides of the home.

In fact, as much 45% of heat loss and gain is from the roof space into the home. This is why roof insulation is so important. In homes that are running heating or cooling this means that a well-insulated home will reduce energy loss substantially.

Many homeowners suffer the summer heat and free in the winter chill. They are unaware of the fact that an insulated home will give them comfort without spending money on heating and cooling. Good quality roof insulation will reduce the heat flow in or out of the roof space by up to 90%. Roof Insulation is one of the best top 10 energy saving tips. Cover your cost in 3 years.

Isotherm Insulation green in color regarded as one of the most Eco-friendly products in the world.  The 145 mm Isotherm has the recommended R-value of 3.70 for the Western Cape region. This insulation has a 30-year guarantee so it will outlast the life of your home. This is our customer’s product of choice.

Aerolite insulation is a glass fiber insulation product and has been on the market for more than 90 years. This is still the most widely used insulation product in the UK and USA. The Think Pink Aerolite 135 mm is SANS compliant and will achieve the R-value of 3.70 as specified for the Western Cape region. To find out more about Aerolite visit this site.

Wall Insulation

American style homes are very energy efficient as the walls floors, as well as the roof space, are all well insulated. Most American homes are timber or Nutec side walls that are well insulated. In South Africa most of our homes are brick. As we know on hot days the brickwork will absorb the heat and the home inside is like a pizza oven.

Well, how can we solve this you may ask. On existing homes, there is nothing that can be done. however, on all new builds, it would be advisable to fit Isoboard between the inner and outer walls. This will reduce heat gain through walls in summer and winter. Most homes will loose up to 35% of their energy through the uninsulated wall.

Floor Insulation

Homes with concrete floors can be insulated to reduce the effect of the cold flowing into the home via the floor. In fact, homes that are built above water retention areas are known to be much colder in winter. Homes on the river’s edge are also affected in the same way.

Fitting Isoboard into the concrete will reduce this heat loss substantially. The Isoboard will ac as an insulation barrier between the cold water and the home inside.

LED Down Lights

This is also a no-brainer. The regular 40 watts or 50 watts downlight run at a temperature of between 275 and 350 degrees C. Installing LED energy saver downlight will dramatically reduce electricity consumption.

Let’s say you are installing 2-watt energy save led downlights. In fact 13 of these light would consume less electricity than one of the standard 40-watt bulbs. Some homes have more than 100 downlights. This will be a massive energy saving when all lights are left on. For example, if energy save LED light were used and all were on they will consume less energy than 7 of the 40-watt lights.

Gas Stoves

Gas stoves are a great way of saving energy in the home.In fact, gas stoves are far more economical to use as the heat is instant. Many homes with electric stoves must wait for a while for the plates to heat up this is wasted energy. All round gas stove is far more economical to run.

Doors for Your Home

Outside doors must be good quality thick wooden doors and must be well treated. Also, make sure the doors seal very well. Make sure you don’t have big gaps at the bottom and if your door put a roll sealer in place. This will prevent the cold air entering the home on very cold days.

Another option is double glazed Aluminium doors as these will reduce heat flow substantially.

In conclusion, we hope these top 10 energy saving tips will be of help. In fact, the top 10 energy saving tips in this article are more for new build homes. However, some of the top 10 energy saving tips can be instituted in existing homes.

So be safe insulate and save energy.
