FAQs

Solar water heaters only utilize solar heat, not stored electrical energy. As a result, during cloudy, rainy, or nighttime weather, solar water heaters still require a higher power consumption to heat water. Therefore, their use remains dependent on weather conditions and can impact unstable electricity consumption.

Meanwhile, with a Daalderop Water Heater, you can enjoy warm water at any time with more stable usage, as it only uses a relatively small amount of electricity for heating. With high-density polyurethane insulation, the temperature remains stable, resulting in energy savings.

Since 1880, Daalderop has been known as a safe and reliable Dutch manufacturer of water heaters. All units are manufactured directly in the Netherlands and distributed in Indonesia through PT. Perwirabhakti Sentrasejahtera since 1993.

Daalderop is available in 6 capacities, which are 15L, 30L, 50L, 80L, 120L and 150L.

Each capacity is designed to meet different needs, from private homes to commercial projects such as hotels and hospitals.

Daalderop is the only water heater which uses dry ceramic element which has no direct contact with water in the tank because it is protected inside an element assembly. This helps minimize the risk of electric shock, making Daalderop a safe choice for everyday water heater use in your home.

Depending on the installation system. If the installation system is not centralized, each bathroom would need 1 unit of Daalderop heaters. With centralized installation system, one house can use only 1 unit of Daalderop heaters, depending on the size of the house and the distance between each bathroom. With centralized installation system, you would save on the cost of purchasing Daalderop and lower electricity costs.

Daalderop is the only water heater in Indonesia that uses pure copper tubes. Copper is known for its rust-resistance and high corrosion resistance, which prevents leaks even after long-term use. It’s proven to be more durable than other tubes made of enameled iron or other materials, which can rust and corrode over time, resulting in leaks and poor water quality.

Daalderop is equipped with TURBO/DUO ELEMENT system, which can be turned on manually to increase the heating process. This feature is available in 30, 60, or 120-minute timers and will automatically turn off after the selected time has elapsed. This makes it a handy way to handle sudden hot water needs without long waits or losing comfort.

Installing a Daalderop unit typically takes just 2–3 hours, as long as the water inlet and outlet lines are prepared. The process is efficient and does not disrupt your home’s activities.

No, you don’t. Daalderop is designed with an automatic temperature control system. Once the water reaches 85°C, it stops using power (0 watts). This means you can keep enjoying hot water without wasting energy or bothering to switch the unit on and off every time.
