Using a geyser blanket
There are conflicting opinions on whether switching a geyser off saves electricity. Some sources suggest that turning the geyser on only when required saves more power. However, others argue that switching the geyser on and off consumes more energy.
Geyser blankets come in various thicknesses, designed to provide specific levels of insulation depending on your home's needs. The thickness options include 50mm, 100mm, and 135mm. The 50mm option is ideal for standard homes or moderate climates, providing effective insulation at an affordable price. The 100mm and 135mm blankets are better suited for larger geysers or homes in colder regions, offering greater insulation and savings.
The cost of installing a geyser blanket is relatively low compared to the potential savings on your energy bill over time. By insulating your geyser, you reduce overall power consumption and protect your appliance from wear and tear, potentially extending its lifespan. Additionally, using a geyser blanket contributes to a greener environment by reducing energy consumption and emissions.
To maximize the energy-saving potential of a geyser blanket, professional installation is recommended. This ensures that the blanket is correctly fitted, providing optimum heat retention and energy efficiency.

Installing a geyser timer
Geyser timers have been around for many years, and their technology has been improved and upgraded over time. They are designed to control a switch that turns a hot water heater on and off during different times of the day, much like how a security light works. This enables the homeowner to control their energy consumption, ensuring the geyser works based on the household's needs rather than its own schedule.
Timers can be particularly useful for larger households with inconsistent schedules, as they can be programmed to adjust the geyser's on and off times for each day, twice a day. For example, a household that typically showers in the morning and evening can program the geyser to heat water during those times, and it will remain off for the rest of the day. This prevents the geyser from running for 24 hours, which can result in high electricity wastage.
It is recommended to hire a qualified electrician to install a geyser timer, as incorrect installation can lead to issues such as a lack of hot water or increased energy consumption. Reputable suppliers with good back-up service and warranties, such as HellermannTyton, can provide support for installations and programming.

Reducing hot water usage
While there are conflicting opinions on whether switching off a geyser saves electricity, there are several ways to reduce hot water usage.
Firstly, installing a geyser timer is a more efficient way of managing electricity demand. This allows you to switch the geyser off during peak demand and operate it according to your household's water usage patterns. You can also automate the on/off times for the geyser, adjusting the schedule for weekdays and weekends.
Secondly, you can reduce hot water usage by lowering the temperature setting on your geyser. According to research, for every 10°F (5.5°C) reduction, you can save 3-5% in energy costs. The standard setting of 140°F (60°C) can be lowered to 120°F (48.9°C) for most households, cutting costs by 6-10%. However, it is important to note that maintaining a temperature of 120°F (48.9°C) may carry a slight risk of promoting legionellae bacteria, so this should be avoided if you have a suppressed immune system or chronic respiratory disease.
Thirdly, you can adopt more efficient shower habits. This includes using low-flow showerheads, taking quicker showers, turning off the water while soaping up, and opting for lukewarm water. You can also install a showerhead with ShowerStart technology, which senses when the hot water arrives and turns off the flow until you are ready to enter the shower. Additionally, consider reusing the water from your shower or bath by scooping it out and using it to flush the toilet or water plants.
Furthermore, you can reduce hot water usage by washing your clothes, dishes, and hands with cold water. About 90% of the energy used by a clothes washer goes into water heating, and cold water washing also helps your clothes last longer. Similarly, you can decrease the temperature settings on your dishwasher to save energy.
Lastly, you can improve the insulation of your geyser and pipes to prevent heat loss. This includes using a geyser or water heater blanket, as well as insulating the hot water pipes to reduce the time needed for hot water to reach the faucet. You can also install check valves on the inlet and outlet of the geyser to prevent heat loss when the pipes are not in use.

Lowering the geyser temperature
Firstly, it is important to note that the geyser should not be set below 55°C, as bacteria thrive at these lower temperatures. The optimum temperature range is 55°C-65°C, with 60°C being the ideal temperature to optimise electricity usage. Lowering the geyser temperature from 70°C to 60°C can save up to 5% of electricity usage.
Secondly, while switching off the geyser will prevent the element from heating the water and using electricity, the water will eventually grow cold, requiring a large amount of energy to reheat it. This is especially true if the geyser is switched off for less than 24 hours, as the heat loss during this time is minimal. Therefore, it is more energy-efficient to maintain a lower, constant temperature than to let the water cool and then reheat it.
Thirdly, other factors that contribute to energy usage include the quality of the geyser's insulation and its proximity to the areas where hot water is needed. Good insulation can reduce heat loss and lower electricity usage. Additionally, installing the geyser closer to the bathroom or areas where hot water is used can reduce heat loss from the water sitting in the pipes.
Finally, while lowering the geyser temperature is effective, combining it with other energy-saving measures can further reduce electricity usage. These include using energy-saving showerheads, installing a geyser timer, utilising solar power, and managing hot water usage by using cold water when possible.

Using energy-saving showerheads
There is a lot of debate about whether switching a geyser off saves electricity. Some people argue that turning it off when not in use saves energy, while others claim that it makes no difference or that it might even increase energy usage due to the high energy required to reheat the water. However, one thing that most people can agree on is that using a geyser timer is a more efficient way of managing electricity demand. By switching the geyser off during peak demand periods and operating it based on the water usage patterns of the household, you can make a significant difference in both cost and demand.
One way to reduce energy consumption and water wastage is to use energy-saving showerheads. These showerheads reduce the flow volume of water by more than half while still maintaining strong water pressure. This means that less hot water is used, which can lead to significant energy and cost savings over time.
There are many different types of energy-saving showerheads available on the market. Some are designed to be low-flow, while others have specific flow ratings or are labelled with a WaterSense certification. WaterSense-labelled showerheads are certified to be 20% more water-efficient than conventional models, and they perform as well as or better than traditional showerheads. By replacing just one standard showerhead with a WaterSense model, you can save up to $55 a year in energy and water costs.
When choosing an energy-saving showerhead, it is important to consider the specific needs of your household. For example, if you have a large family or live in an area with water restrictions, you may want to prioritize a showerhead with a lower flow rating, such as 2.0 gallons per minute or lower. Additionally, some showerheads are designed to be handheld, while others are fixed, so you can choose the option that best suits your preferences and shower setup.
Installing an energy-saving showerhead is usually a straightforward process, but it is always a good idea to refer to the manufacturer's instructions or seek professional help if needed. By making this small change, you can not only reduce your environmental impact but also lower your utility bills.
