Busting Common Water Heating Myths and Misconceptions

In most homes, a water heater is one of those quiet appliances that works behind the scenes but becomes indispensable the moment winter sets in. Yet, despite its importance, there are countless misconceptions about how it works, how much power it uses, and what type is best. Many of these myths lead people to misuse their geysers or buy the wrong models. 

Once you know how a geyser functions, it helps you save energy, reduce bills, and extend the appliance’s lifespan. This article breaks down six common myths about water heaters and brings out the facts that help you make smarter, more cost-efficient decisions for your home. 

Myth 1: Leaving the geyser on all day saves electricity 

It's a common belief that keeping the geyser on throughout the day saves power because it avoids reheating water from scratch. The truth is the opposite. When a geyser stays switched on, it continuously works to maintain the water temperature inside the tank. This process, known as standby heat loss, wastes energy even when no one is using hot water. 

Modern electric water heater models heat water efficiently and reach the desired temperature within minutes. Turning the appliance off when not in use can drastically reduce electricity consumption. You can also install a timer to automate operations for specific hours of the day.  

Myth 2: Bigger geysers always perform better 

Many people assume that a larger geyser automatically means better performance or more comfort. But bigger isn’t always better. Choosing a large capacity model for a small family means heating more water than required. This leads to unnecessary energy use and higher bills. 

The best approach is to select a capacity that matches your daily requirements. For example, a 10-litre geyser is enough for a single person’s daily shower, while a 25-litre storage geyser works well for a family of four. If your water usage is low or limited to quick tasks, an instant water heater for the bathroom can meet your needs without any energy waste. 

When sizing your geyser, consider both family size and the frequency of use. Buying the right capacity ensures faster heating, optimal energy use, and better long-term efficiency. 

Myth 3: Instant geysers are always more energy-efficient 

While instant geysers heat water only when needed and avoid standby losses, that doesn’t always make them the most energy-efficient option. These models operate at higher wattage (3kW or more) and can draw more power when used for longer showers or large volumes of water. 

A storage geyser heats a set volume of water and maintains it for repeated use throughout the day. For families that require continuous hot water, storage models are a better option. Instant units are perfect for smaller tasks, such as washing utensils or short showers. 

Ultimately, both serve specific purposes. Matching the heater type to your household’s routine helps you optimise consumption and extend appliance life. 

Myth 4: Geysers don’t need maintenance 

Another widespread misconception is that water heaters run fine without any maintenance. Over time, minerals and sediments from water build up inside the tank or heating element. This reduces efficiency and heating speed. If you ignore these issues, it can cause damage or shorten the lifespan of your geyser. 

Routine checks once or twice a year are essential. Cleaning the tank, inspecting the thermostat, and checking safety valves prevent corrosion and give consistent heating. In areas with hard water, descaling is important to keep heating elements clean. 

If you use a kitchen water heater or small-capacity geyser a lot, frequent preventive maintenance increases the lifespan of the appliance. Many modern models also feature anti-corrosive inner tanks that minimise deposits and reduce the need for frequent servicing. 

A hot water heater with a 5-star energy rating uses advanced heating elements and thermostat systems that regulate temperature precisely and don't waste energy. Some include energy-saving modes that automatically adjust heating cycles based on usage patterns. 

Selecting an energy-efficient geyser from a reliable brand can help you save up to 30% on electricity compared to older or unregulated models. Remember, efficiency also depends on how you use the appliance. Turning it off after use and maintaining a moderate thermostat setting (around 55°C) can make a big difference. 

Myth 6: All geysers work the same way 

Not all geysers function in the same way. Each type is designed for specific needs. Instant or tankless models provide quick heating for short-duration tasks, while storage geysers are good for larger households with continuous hot water demand. Solar and gas-based models cater to regions with specific energy preferences or frequent power cuts. 

For instance, if you want something compact for your cooking area, a gijar or small-capacity wall-mounted heater works well. On the other hand, a storage unit in the bathroom ensures a comfortable shower for the entire family. 

Instead of buying geysers based only on price or design, consider water consumption patterns, available space, and energy sources to find a model that fits your lifestyle.
