Daichi Digital Temperature Control Instant Electric Water Heater Geyser Shower RP-55

It is recommended to be used for one washroom. You can either use it as a separate shower or use it for the complete washroom. The pressures of the geyser would be enough to run hot water from one tap at a time. Using it for multiple washrooms or multiple taps at the same time could decrease the water pressure.

Fast electric water heaters typically take around 30 minutes to heat a tank with a capacity of 10–50 liters. After heating, they operate at a base power to maintain the water’s temperature, turning on 3–4 times per day at their full rated power. Additionally, whenever hot water is used, the heater activates again at full power for approximately 30 minutes to reheat the tank. For a single washroom, this means the heater runs at its full rated power (usually 2000W) for at least 6–7 hours daily, consuming around 12–16 units of electricity per day. This results in monthly electricity bills of approximately Rs. 16,000–21,000. In contrast, the Daichi instant water heater only operates when water is being used. For a single washroom, it would typically run for about 40 minutes per day. Even at a high temperature of 45°C, it consumes just 3 units of electricity per day, leading to monthly electricity bills of less than Rs. 4,500. By switching to a Daichi instant water heater, you can save approximately Rs. 12,000–15,000 per month on electricity bills compared to fast electric geysers. Note: These are rough calculations verified by Shopping Jin’s own experiment.

When operating at 30°C, it consumes 2100 watts of power. If you operate it at a maximum of 55°C, it will consume 5500 watts of power. On average, people use it at 40°C–45°C, and it consumes 3000-3500 watts of power.

Fast electric geysers take at least 30 minutes to completely heat up their water tank, while instant electric geysers take just 3–10 seconds to provide you with hot water. Fast electric geysers have a limited capacity of 10–50 liters, so they provide a limited supply of hot water. In contrast, instant geysers offer an unlimited supply of hot water. The temperature of the water from fast geysers keeps decreasing as you use it, and within 10–20 minutes (depending on the capacity of the geyser), there will be no hot water. However, instant geysers provide non-stop hot water at a fixed temperature that you’ve set. In short, the Daichi instant electric geyser saves you time, water, and money, and provides a better bathing and washing experience.
