How to save energy with a geyser

As winter approaches the use of geysers increases in many homes. While some people use them only during cold weather others need warm water throughout the year.  However leaving a geyser running longer than necessary can increase energy costs and waste water.

Many geysers have an automatic cut-off feature that stops heating when the set temperature is reached.

This feature helps control heating, but it does not guarantee lower energy bills. The amount of gas or electricity used depends on the type of geyser its settings and how often you use it.

With a few simple habits you can enjoy warm water while managing your household expenses and using water more carefully.

What is the right geyser temperature?

A temperature setting of around 50–60°C may be suitable for some household water heaters depending on the manufacturer’s instructions and the home’s hot water system. Avoid setting the temperature higher than necessary.

Water at around 37–40°C may feel comfortable for bathing, although personal preferences can vary. If the water is too hot mix it with cold water before use.

Remember that the temperature inside the geyser may be different from the temperature of the water coming out of the tap.

Safety tip

Always check the water temperature before bathing children or older adults, as very hot water can cause burns. Do not rely on a fixed heating time, such as 10 or 15 minutes because the time needed depends on the geyser’s size, power and starting water temperature.

How to save gas with a gas geyser

Gas consumption depends on the geyser’s design heating temperature usage and condition.

Follow these simple steps to avoid unnecessary gas use

Set the temperature according to your needs and the manufacturer’s instructions. Avoid heating water to an unnecessarily high temperature.

Turn off the geyser after use if its operating instructions recommend doing so. Arrange regular maintenance to keep the appliance working efficiently.

If the flame heating performance or gas supply seems unusual contact a qualified technician.

Never change safety settings or attempt repairs yourself. Proper maintenance can also help identify gas leaks and other problems before they become dangerous.

How much electricity does an electric geyser use?

The electricity consumption of an electric geyser depends on its power rating and how long its heating element operates.

For example, a 3,000-watt (3-kilowatt) geyser uses approximately three units of electricity if it heats continuously for one hour.

Daily heating time

•Approximate monthly use

•1 hour per day

•90 units

•2 hours per day

•180 units

These estimates assume the heating element runs continuously. Actual consumption may be lower if the geyser automatically stops heating after reaching the set temperature. To save electricity heat only the amount of water you need and avoid keeping the water hotter than necessary.

How long before bathing should you turn it on?

There is no single heating time that works for every geyser. Small units may heat water quickly while larger storage tanks usually need more time. Check the manufacturer’s instructions to learn how long your model takes to heat water safely.

Instant water heaters work differently from storage geysers. Follow the instructions for your particular model and avoid changing its settings without proper guidance.

Simple ways to save water

Saving hot water can also reduce the energy needed to heat it. Here are a few useful habits. Use a bucket for bathing if it helps you control the amount of water used.

Keep showers short.

Turn off the tap when you do not need running water.

Repair leaking taps and pipes.

Avoid letting heated water run down the drain while waiting unnecessarily.

These small changes can help reduce water waste and the gas or electricity needed to heat it.

Keep your geyser clean and safe

Minerals in water can build up inside a geyser over time.  This buildup may affect heating performance and increase the time needed to heat water.

If your geyser takes longer than usual to heat water makes unusual noises or fails to provide enough hot water have it checked by a qualified technician.

Gas geysers also need proper ventilation. Never operate a gas burning appliance in a sealed space without suitable ventilation, as dangerous carbon monoxide can build up.

If you smell gas do not light a flame or operate electrical switches. Leave the area and contact your gas supplier or emergency service from a safe location. For electric geysers have the wiring earthing and safety controls checked by a qualified electrician when needed.

What to consider when buying a new geyser

If you plan to replace your geyser consider your household’s hot water needs, the number of people in your home, the availability of gas and electricity and the appliance’s energy efficiency. Choose a model that suits your household rather than one that is larger or more powerful than necessary.

Tips

You do not need to sacrifice comfort to reduce your energy bills. Use your geyser only as needed choose sensible temperature settings prevent water waste and arrange regular maintenance.  These simple habits can help control gas and electricity costs while keeping your home safe.
