Year-round comfort at home
The ATTACK Inverter R32 heat pump extracts energy from the outdoor air and transfers it to a water-based heating system. Its monobloc configuration provides heating and cooling and prepares domestic hot water in an external tank. The range includes five models from 6 to 19 kW.
The 6 to 12 kW models have one fan; the 15 and 19 kW models have two.

Year-round operation
An ideal solution for modern new homes with an A0 energy rating. Its A+++ seasonal heating efficiency can also help reduce costs in renovated homes. An air-to-water heat pump system is one of the most cost-effective heat pump options.
Installation
An ATTACK Inverter R32 can be installed by a heating engineer without refrigeration certification; only the heating circuit and electrical supply need to be connected. The monobloc outdoor unit contains all required components, while the compact wall-mounted indoor unit suits installations that retain an existing DHW tank or have limited space.
