9 Frequently Asked Questions About Geyser Timers

1. What Are Geyser Timers?

Geyser timers are devices that are used to control the operation of water geysers. They are designed to automate the heating process and regulate the usage of hot water in a household. A geyser timer typically allows you to set specific times for the geyser to be turned on and off and so ensuring that hot water is available when it is needed while saving energy during periods of non-use. These timers can be programmable, allowing you to customise your schedules based on your daily routines and preferences. Some geyser timers even offer a wifi geyser timer which allows you to control the geyser timer settings from the convenience of your phone.

Geyser timers not only promote energy efficiency and cost savings by reducing unnecessary heating, but they also contribute to the overall convenience and comfort of a home by ensuring a consistent supply of hot water.

2. Why Should You Have a Geyser Timer Installed?

Having a geyser timer installed in your home can bring several benefits that can make it a worthwhile investment. Here are some reasons why you should consider getting a geyser timer:

Energy Efficiency

One of the main advantages of a geyser timer is that it promotes energy efficiency. By setting specific times for the geyser to be turned on and off, you can avoid heating water when it’s not needed, such as during the night or when you’re away from home. This helps to reduce energy consumption and lowers your electricity costs.

Cost Savings

With reduced energy usage comes cost savings. By optimising the operation of your geyser, a timer can help you save money on your monthly energy bills. Over time, these savings can add up significantly, making a geyser timer a financially savvy choice.

Unparalleled Convenience

A geyser timer offers convenience by ensuring a consistent supply of hot water at the times you need it most. You can program the timer to have hot water ready for your morning shower or when you return home from work. This eliminates the need to wait for the water to heat up, saving you time and providing added convenience.

Extend geyser Lifespan

A timer can help extend the lifespan of your geyser by controlling the operation of your geyser. Continuous operation and overheating can put stress on the appliance, and this can lead to wear and tear over time. By regulating the heating cycles, a geyser timer helps to reduce this strain and can prolong the life of your geyser.

Environmental Impact

Using a geyser timer aligns with sustainable practices and reduces your carbon footprint. By conserving energy, you contribute to the preservation of natural resources and help mitigate the effects of climate change.

Installing a geyser timer offers multiple advantages, including energy efficiency, cost savings, convenience, an extended lifespan for your geyser as well as a positive environmental impact. It’s a wise choice that not only benefits your household but also promotes sustainable living.

3. Does a Geyser Timer Save Electricity?

A geyser timer can save electricity and reduce energy consumption by allowing users to program specific time slots for the geyser to operate. This timer ensures that hot water is available only when needed. This means that the geyser will not be continuously heating water throughout the day, which can result in significant energy wastage. 

Instead, the timer enables the geyser to operate during specific periods, such as a specific time in the morning and evening when hot water is typically required. As a result, unnecessary heating when no one is using hot water is avoided, leading to reduced electricity usage. This efficient use of energy not only benefits the environment but also helps lower electricity bills.

4. How to Install a Geyser Timer?

Here is a step-by-step guide explaining how to install a geyser timer:

Step 1: Apply all safety measures

Switch off the circuit breaker as well as the isolator switch and use a multimeter to ensure that there is no electrical current in the wires in order to avoid an electrical shock.

Step 2: Install the control box

This should be installed in a dry place close to the isolator switch, and it is important that it isn’t exposed to the elements. Carefully follow the manufacturer’s instructions that are specific to the timer that you have bought.

Step 3: Install the display unit (if your geyser timer has one)

This should be installed in a location that is easily accessible to you so that you can set the timer and see the temperature (but it should be safely out of the reach of children).

Step 4: Secure the connections

Ensure that all the wires that have been connected are secure and have been connected correctly.

Step 5: Set your timer

Follow the manufacturer instructions that were provided with the timer to set the timer according to your preferences. You can choose specific days and times that the geyser should start heating up, as well as to what temperature it should heat up to.

Step 6: Test the installation

Once you have set the times and temperatures, do a test and see if the geyser does indeed heat up and that it heats up to the temperature that you have set.

Installing a geyser timer switch may not seem too complicated, but it is always a good idea to rather call expert plumbers at plumbing companies in Cape Town, such as the team at Absolute Plumbing, who can safely and securely install your geyser timer so that you don’t have to worry about any electrical hazards.

5. How to Set a Geyser Timer?

In order to set a geyser timer, you will need to start by locating the timer switch, which is usually near the water heater or in the distribution board. You have located this; decide what times of the day you would like the heater to turn on and off. For example, if you want the geyser to start heating at 6 am and stop heating at 9 am, then set the timer accordingly. It is best to follow the manufacturer’s instructions for your heater in order to adjust the timer settings accurately and make sure that the timer is properly connected to the geyser. 

After setting up the timer, your water heater will only heat during the designated periods, which can significantly help conserve electricity and save money. It’s important to note that specific instructions may vary depending on the brand and model of the geyser timer, so it is important to consult the user manual that came with your appliance.

6. How to Reset a Geyser Timer?

Sometimes you might want to reset your geyser timer to its factory settings, and this is a fairly straightforward process. For safety purposes, it is a good idea to first turn off the power supply to the geyser. You will then need to locate your geyser timer, which is typically found near the water heater or on the distribution board. Then identify the reset button on the timer. It can often be a recessed button that may require a small tool like a paperclip to press.  

Next, press and hold the reset button for a few seconds to reset the timer back to its default settings. Once it has reset, you can reprogram the timer with the settings you want by following the manufacturer’s instructions. Finally, restore power to the geyser and observe if the timer operates correctly based on the new settings. Remember to consult the specific instruction manual for your geyser timer for accurate guidance about your model.

7. Why Would You Need to Bypass a Geyser Timer?

There are various reasons why you might need to bypass your geyser timer:

  • Urgent hot water needs: If there is an immediate need for hot water outside of the programmed timer settings, bypassing the timer allows for instant access to hot water.
  • Maintenance or repairs: During maintenance or repair work on the geyser or any associated plumbing, it may be necessary to bypass the timer temporarily to ensure an uninterrupted hot water supply.
  • Testing or troubleshooting: Bypassing the timer can be helpful when testing or troubleshooting any issues related to the geyser or the timer itself, allowing for direct control over the heating element.
  • Changing usage patterns: If there is a change in the household’s hot water usage patterns, such as different showering or bathing times, bypassing the timer may provide more flexibility in accessing hot water at desired times.

8. How to Bypass a Geyser Timer?

Bypassing a geyser timer is not recommended unless absolutely necessary, but if you do need to bypass the timer temporarily, it is best to follow the steps according to the manufacturer’s instructions. Otherwise, search for ‘plumbers near me’ on the internet and call a plumber, such as those at Absolute Plumbing, who will be able to assist with their expert plumbing services.

9. How Long Does a Geyser Take to Heat Up?

Depending on the size of your geyser, heating up the water from cold can take up to 4 hours, although there are a few other factors that play a role in how long it takes for a geyser to heat up. One of the most important factors is the temperature of the water in the tank, which would be colder during winter due to the groundwater being colder. The temperature on the thermostat, how insulated the geyser is, as well as the condition of the geyser would all play a role. 

The best way to determine the duration it takes for your geyser to heat up it is to follow these steps: First, switch off the geyser and wait until the hot water supply is depleted. Then, turn it back on and monitor the water temperature at hourly intervals until it reaches the desired temperature. While this approach may require some time and patience, it remains the most reliable method to gauge the time it takes for your specific water heater to heat up.
