Frequently Asked Questions - HEATANK V4 AIHD 150L DAITSU
How does the Daitsu HEATANK V4 AIHD 150L heat pump water heater work?
The unit extracts heat from the surrounding air using a refrigerant cycle, compresses it to raise the temperature, and transfers it to the water in the 150-liter tank. This process is up to 3.5 times more efficient than conventional electric heating.
What are the installation requirements for this water heater?
The heater must be installed indoors on a level, sturdy floor with adequate clearance around the unit for air circulation. It requires a 230V / 50Hz power supply and proper drainage for condensate. We recommend professional installation.
How much hot water can I get from a 150-liter tank?
With a 150-liter capacity, you can expect enough hot water for a family of 3-4 people for daily showers and washing, especially when the heat pump runs efficiently and maintains temperature.
Can I use the water heater during winter or cold weather?
Yes, the HEATANK V4 is designed to operate in ambient temperatures as low as -7°C. In very cold conditions, the backup 2.0 kW electric heater engages to ensure consistent hot water supply.
How often should I perform maintenance on this unit?
We recommend inspecting the anode rod every 2 years and descaling the tank every 3-5 years, depending on water hardness. Regular maintenance ensures longevity and efficiency.
What safety features does the HEATANK V4 include?
It includes overheating protection, a pressure relief valve, and a sacrificial anode rod to prevent corrosion. The electrical components are also protected with IPX4 splash resistance.
Is the water heater noisy during operation?
No, the heat pump operates quietly at under 50 dB(A), similar to a whisper. This makes it suitable for indoor installation without causing disturbance.
Can I set a timer or schedule for heating?
Yes, the unit features a digital display and timer function, allowing you to schedule heating during off-peak electricity hours to save energy.
What type of refrigerant is used, and is it eco-friendly?
The heater uses R134a refrigerant, which is chlorine-free and has zero ozone depletion potential, making it more environmentally friendly than older alternatives.
Are spare parts available and is the unit repairable?
Yes, the HEATANK V4 features modular components for easy servicing. Spare parts such as compressors, control boards, and heating elements are available through Daitsu's authorized service centers.
