Air Source Heat Pump – Air To Water AquaThermica for Domestic Hot Water

The TESY AquaThermica is a wall hung Compact Air Source Heat Pump for generating hot water for domestic hot water. The TESY COMPACT AquaThermica incorporates a built in air source heat pump and 150 litre hot water cylinder to offer one compact appliance that is designed to be installed in your property. It has a capacity of 150 litres of water and offers a maximum water temperature of 60 degrees. The appliance has an efficiency rating of A+ making it one of the most efficient water heaters in its class. It is powered by 220-240V power supply that is wired via a fused spur.

The heat pump requires connection of 125mm diameter intake and exhaust air hoses, that connect to the top of the appliance.

The Compact AquaThermica offers a state-of-the-art, compact solution to creating energy efficient hot water for domestic hot water. It is an environmentally friendly product, operating with renewable energy sources resulting in lower CO2 emissions. The appliance is highly efficient with a precisely balanced refrigerant cycle due to an electronically commutated motor and an electronic expansion valve resulting in 75% lower electricity consumption when compared to similar sized electric hot water cylinders.

The appliance includes a user friendly programmable LCD touch control screen and a built in diagnostics control system.

Exhaust and Intake Hoses Not Included – 125mm diameter. 

IMPORTANT: This appliance must be installed in accordance with G3 un-vented hot water regulations and requires 2 forms of safety device to be installed on the hot side of the pipework. We recommend installing an 8 litre safety expansion vessel £34.99 and a 3.5 bar pressure release valve £14.99. If you have any technical questions prior to buying on eBay please call 0161 439 1400.
