The AquaPlus APAIO200 is an all-in-one heat pump water heater: a single cabinet integrating a microchannel heat exchanger, R290 refrigerant circuit and a 200 L vitreous enamel lined steel tank. It delivers 2.78 kW of heating with a rated power input of 1.2 kW and a COP of 4.15 (air 20C/15C, water 15C to 55C), and operates across an ambient range of -7 to 43 degrees C.
R290 is a natural refrigerant with a low GWP. The unit carries a 1.8 kW electric booster element for boost and manual sterilization modes, and a touchscreen controller with timer, automatic defrost and WiFi (Tuya) connectivity. Net weight is 104 kg, sound level 43 dB.
The manufacturer offers a 6 year warranty: 1 year parts and labour, the remaining 5 years parts only. The manual (branded HSA/Hunt Heating, sold as AquaPlus) covers both APAIO200 and APAIO270 as the same product family across two tank sizes.
