The Power Behind your Hot Water

Outdoor Heat Pump

Our sleek outdoor heat pump is the heart of the system. Already trusted in Japan for nearly 20 years, it delivers consistent and reliable performance.

Using natural CO2 refrigerant, it's one of the cleanest and most efficient ways to heat water for your home.

How It Works

  • Takes heat from the air – even on cool days.
  • Transfers that heat to the water system through advanced technology.
  • Pumps hot water into your tank – ready whenever you need it.

Why You'll Love It

  • Compact and stylish – easy to place inside or outside your home.
  • Eco-friendly CO2 refrigerant – lowers your carbon footprint.
  • Proven, long-lasting performance.

Hot Water Tank

The water tank works hand-in-hand with the outdoor unit to deliver a steady supply of hot water. Cold mains water goes in, perfectly heated water comes out – ready for your showers, baths, kitchen, and laundry, giving your household reliable comfort day after day.

How It Works

  • Cold water enters at the bottom of the tank.
  • Heated water from the outdoor unit is stored at the top.
  • When you turn on the tap, tempered water (around 50°C to 63°C) flows out – safe, comfortable, and reliable.

Safe and Smart

  • Pressure and Temperature Relief Valve (PTRV): Releases pressure and heat if it ever gets too high.
  • Expansion Control Valve (ECV): Prevents damage from water expansion inside the tank.
  • Peace of mind: consistent hot water with built-in safety protection.
