4. We at Masiza, are well informed about South Africa’s current power shortages
and have sourced thorough information regarding the major causes of the
issue.
From our findings, we then decided to make it our first project to penetrate the
market, our service being to inform our citizens further. People need to stop
pointing fingers at Eskom because we all contribute to the problem, matter of
fact without the people there is no problem. Negativity will not carry us
forward, with positive thinking we can become the solution.
We are launching #NCIPHISA MZANSi, a researching and implementing
campaign that will save South Africa’s natural resources by getting people to
reduce their usage and avoid unnecessary utilities.
5. South Africa is currently experiencing power shortages, with Eskom failing to meet the
demand in peak hours.
Geysers and swimming pool pumps have been proven to be the major electricity
consumers compared to other appliances. We cannot ignore that dirty swimming pools
create an unhealthy environment, so the pumps need to be on for at least 6 hours a day.
The are control measures for that, but people tend to ignore them. As for geysers, the
majority prefers their water warm for their early morning and evening sequences.
What about manufacturing companies that use electric machinery all day, the offices in the
CBD that have air-conditioning systems running all day long and the hotels that have
geysers on in unoccupied rooms. Every one is responsible for the energy shortages. Their
attitude: so what, we pay for it anyway.
We cannot create a problem by consuming unreasonably, running out and conclude that
increasing the supply is the solution. This will soon become a cycle should we not change
our ways.
6. HOW A GEYSER OPERATES WITHOUT A TIMER:
With the geyser permanently on, every time the water temperature in the geyser falls
below the set temperature, it automatically switches on again to maintain the set
temperature.
The temperature drops 2 to 5 degrees every approximately every hour. When that
occurs, the thermostat switches the element back on and heats the water back up to
65 – 70 degrees. This means that the geyser switches on and off 24 to 30 times a day.
This is equivalent power of 50 light bulbs.
According to Eskom, nearly 5.4 million electric geysers in South Africa contribute about
2 940 Mega Watts of electricity to the evening peak (5pm to 9pm). This is enough to
power a big city the size of Durban.
7. WHAT IS A GEYSER TIMER:
A Geyser timer is a simple digital device that is fitted into your distribution box,
doing exactly what it says, controlling the time which a geyser switches on and off
during the course of the day. This device is old in existence but we feel that its
marketing wasn’t done properly, therefore most of our home owners are unaware of
such.
HOW IT OPERATES:
What is good about it, is that you can set the times you want your geyser to come on
and off. For it to work effectively, one must know exactly when they need hot water
and set it to switch the geyser on at least an hour before the first person’s shower
time. When it should switch off? We advise that it switches off 2 hours after the last
person’s shower, just to have hot water available for other uses that occur during the
day, like washing dishes. Should you have visitors, worry not because there is a by-
pass button.
8. An average family uses less than 4 hours of hot water per day, which means the other
20 hours of heated water goes to waste. Mathematical calculations (4 x 30) tell us that
the family only needs 120 hours of hot water per month. This educates us, that they
pay for 600 hours of hot water per month, that they will never use.
WORKED EXAMPLE: The family is charged R 1 821.96 on their Metro Bill per month and
the following items make up the total.
1. Water meter = R377.36
2. Water loss levy = R9.42
3. Sewage disposal = R83.42
4. Domestic refuse = R74.88
5. Monthly rates = 478.04
6. Electricity = R798.84
9.
10. 17%
83%
WATER HEATING
USED
UNUSED
With the geyser contributing 43% to the electricity cost, this concludes to R343.50.
From that amount, only R58.40 is that of used heated water and R285.10 remains
unused per month. Paying R285.10 less on electricity monthly is beneficiary.
Provisionally, you will be saving R3421.20 per year. Owning one is definitely an
investment.

14. Fortunately, there are further energy saving measures other than solar
power. Geyser blankets and pipe insulators contribute greatly to
temperature maintenance, keeping your heated water hot for a longer
period.
Geyser blankets cut the temperature drops by half, which means it will
then drop 1 degree Celsius every two hours, instead of one.
The reflective aluminum foil (material used to manufacture
geyser blanket) encases the insulation layers, causing the radiant heat
to be reflected back and contained within the geyser unit.
Insulation differs in sizes: 50mm or 75mm thick & maximum at
150mm for the large geysers. The thicker, the better.

16. Copper and steel pipes are known to be fluent water transporters,
but are naturally cold elements unless exposed to the sun. For
water to be kept in such, the temperature drops from hot to warm,
then to cold. This is why when opening the tap for hot water we
get cold water flowing out for a certain period of time.
Quick proven fact: 4 full & 1 three quarters full glasses of clean
cold water flow out to waste while you wait for hot water to flow
out your tap. This is 1.5 litres combined, multiplied by your house
hold members and the quantity of occurrence per person.
Dressing up your hot water pipes also maintains the current
temperature in your water, saving you time, water, electricity and
money.
