The new high-efficiency heat pumps for indoor installation feature a flexible air circuit and a simple hydraulic connection. The outside air is drawn in at the back of the device. No air ducts are required. Thanks to the EC 3D radial fan, the air outlet can be on the left, right or top of the casing (as needed). The hydraulic connection of the heat pump can be perfectly adjusted to the given conditions. For installation, the flow and return can lead into the casing from the left or the right, as required.

The benefits at a glance:

• Variable air outlet to the left, right or top with the
• option of relocating the hydraulic connections from the right to the left
• Electronic expansion valve for high seasonal performance factors and low operating costs
• Free-swinging compressor baseplate and slow-running EC radial fan for low noise emissions
• WPM EconPlus heat pump manager with integrated thermal energy metering and flow switch for high operational safety
• Compact dimensions for space-saving installation - installation with built-under buffer tank PSP 120E possible
