Introduction
In Malaysia, hot showers are no longer just a luxury, they’ve become part of daily comfort, whether it’s winding down after a long day or refreshing during the rainy season. Yet, many homeowners don’t realise that water heating is one of the biggest contributors to rising TNB electricity bills. Conventional storage water heaters, with their outdated designs and poor insulation, often waste significant amounts of energy.
These inefficiencies not only drive up monthly expenses but also lead to more frequent maintenance issues and shorter product lifespans. For families mindful of household costs and bathroom space, this can quickly become a frustrating burden.
The Esio Storage Water Heater is designed to change that. With advanced technology, durable build quality, and a focus on efficiency, it helps Malaysians cut down on electricity bills while delivering consistent, reliable hot water for the whole family.

Smarter Design, Smaller Bills
Frequent Problems in Malaysia
Many Malaysians believe that turning on the water heater only right before showering helps save electricity. In reality, this practice often backfires. It creates longer waiting times for the water to heat up and can trigger unnecessary reheating cycles, wasting more energy in the process.
Conventional storage water heaters are essentially just large boiling pots. They are lack of built with efficiency in mind, which leads to several everyday frustrations for families:
Energy Waste
Traditional tanks act like oversized kettles. With minimal insulation, heat escapes rapidly into the surrounding bathroom environment. As the water cools, the heater must switch on again to maintain temperature, consuming electricity even when no one is using hot water. Over time, this constant reheating significantly inflates household TNB bills.

Fluctuating Water Temperature
A common complaint in families is inconsistent shower temperatures. This happens because conventional tanks allow cold inlet water to mix freely with stored hot water. The result is sudden drops in temperature, especially noticeable when multiple family members shower back-to-back or when someone uses hot water at the sink while another person is showering. Instead of comfort, users often get an irritating “cold-hot-cold” showering experience.
Space Limitations
Malaysian homes and condos often have compact bathrooms where every inch counts. Conventional water heaters tend to be bulky, with large tanks mounted high on the wall or hidden in awkward corners. Not only do they take up precious space, but installation can also limit design flexibility, making bathrooms feel smaller and less practical.

Improved Heating Elements for Faster, Cleaner Heating
Frequent Problems in Malaysia
In many parts of Malaysia, ongoing construction and aging water infrastructure allow mud, sand, and other impurities to enter the water supply. When this happens, conventional copper heating elements in storage water heaters are especially vulnerable.
These impurities quickly accelerate corrosion and scaling, coating the heating element and reducing its efficiency. Over time, this creates several issues for households:
Slower Heating Times
What used to take a few minutes can stretch to much longer as buildup thickens. Families are left waiting for the tank to catch up, especially frustrating during busy mornings or when multiple people need hot water quickly.
Higher Electricity Bills
Because the heating element is working against a layer of corrosion and scale, it consumes significantly more electricity. This inefficiency often shows up in monthly TNB bills, where families notice rising costs without understanding the hidden cause.
Frequent Breakdowns
Over time, the buildup doesn’t just slow heating, it eats away at the element itself. Corroded elements are more prone to cracking, short-circuiting, or burning out entirely. For households that rely on daily hot water, this leads to costly repairs, premature replacements, and unnecessary service calls.
Reduced Water Quality
In some cases, scaling and rust from deteriorating elements can leach into the water, causing discoloured water, metallic taste, or unpleasant odours. While not always dangerous, it diminishes the sense of cleanliness and comfort that hot showers are supposed to provide.
The Esio Advantage
Esio is built with smarter engineering to solve the pain points Malaysian households face with conventional storage heaters:
Steady Temperature for Every Shower

Superior Tank Insulation: Guarding Against Standby Heat Loss
Frequent Problems in Malaysia
Most conventional storage water heaters come with only about 2 cm of insulation, barely enough to keep water warm for long. This thin barrier allows heat to escape quickly in between showers. As a result, families often find themselves needing to switch the heater back on or run multiple reheating cycles throughout the day.
The timing of these reheating cycles also matters. In Malaysia, TNB electricity tariffs are higher during peak hours, weekdays from 2pm to 10pm, precisely when families need hot water the most afterwork and after school. This means poor insulation doesn’t just waste energy, it also makes households pay more for the energy they do use.
Example Scenario
Take a typical Malaysian family of 5, where each person showers for about 10 minutes twice a day, adding up to 100 minutes of hot water usage daily.
-
Instant Water Heater (3.8 kW)
Heats water directly during use. For 100 minutes of showering, it consumes about 6.3 kWh of electricity. -
100L Storage Water Heater (65℃)
Fully heating the tank requires only 2.52 kWh. This supplies around 60 minutes of showering at 38℃. To meet the 100-minute demand, the total energy use is about 4.18 kWh.
That’s a savings of over 30% compared to the instant water heater, while still delivering the same comfort.
The difference lies in heat retention. With proper insulation, a storage water heater keeps the tank warm for hours, meaning the same batch of heated water can be used by multiple family members without reheating. Poorly insulated tanks, on the other hand, lose heat so quickly that the heater is forced to re-activate frequently, burning through electricity even when no one is in the shower.
The Esio Advantage
Esio takes insulation seriously, solving one of the biggest weaknesses of conventional storage water heaters.
4 cm German BASF Insulation Foam
Unlike standard heaters that use only 2 cm of insulation, Esio is built with double the thickness, using high-quality German BASF insulation for superior heat retention.
Hot Water That Lasts
With stronger insulation, water stays hot for much longer, drastically reducing the need for reheating cycles between showers.
Lower Bills, More Convenience
Families save electricity without sacrificing comfort. Whether it’s the busy morning rush or late-night relaxation, hot water is always ready, without the stress of long waiting times or high TNB charges.
By guarding against standby heat loss, Esio ensures Malaysian households enjoy efficient, ready-to-use hot water with real energy savings built in.
