CS3400i

Compact enough to be missed, and quiet enough to go unnoticed, the CS3400i AWS pairs an indoor and outdoor unit together. Instead of a larger monobloc design, this smaller and more flexible site unit is the perfect fit for busier neighborhoods. And there’s a much wider choice of where you can install, as the unit typically requires no planning permission.

The 3400i AWS offers a range of outputs to match your needs, from 4kW to 10kW. These outdoor units have been thoughtfully designed to be both quiet and space-saving, making them the perfect solution for maximizing garden space in both new and existing builds.

The pre-configured indoor unit is quick and easy to install with a built-in multi-functional backup electric booster for heating and hot water.

A great option for hybrid installations bringing boilers and heat pumps together with the hybrid unit that can be coupled with the 4-8kW outdoor units.
