Where to Place your Heat Pump

1. Installed Beside the Building

Placing the outdoor unit against an external wall is the most common and practical choice. The compact and low-noise design of Kronoterm’s ADAPT and VERSI units means they can sit close to the property without disturbing residents or neighbours. This position provides:

• Shorter pipe runs for improved efficiency

• Simple maintenance access

• Reliable airflow around the unit

Modern units are designed to be visually unobtrusive, so they no longer need to be hidden behind screens or boxed-in structures, they integrate naturally beside the home. As the units are grilled on both sides they cover the unsightly evaporator and so can be fitted sideways against a wall.

2. Mounted on a Balcony or Terrace

In multi-storey buildings, such as flats or apartments, balconies and terraces offer an ideal alternative. Compact systems — especially the VERSI heat pump — are engineered for small spaces and quiet operation, making them suitable for close-proximity living.

When installed safely and with sufficient airflow clearance, balcony placement can be both efficient and discreet.

3. Placed in an Attic, Loft or Basement (Indoor/Hybrid Installations)

For properties where external placement is impractical or restricted, the ADAPT and VERSI models can be installed in attic or basement areas using smart ducting for air intake and exhaust.

This setup is a great fit when the goal is to keep the outdoor unit completely out of sight while maintaining full system performance.

4. Geothermal Systems – No Outdoor Unit Required

For homes using Kronoterm’s ETERA geothermal solutions, there is no need for an external heat pump unit at all. These systems use underground collectors to extract heat, making them the most space-efficient and visually discreet option available.

Where You Shouldn’t Put an Outdoor Unit

While modern heat pumps are flexible, certain locations can reduce efficiency or cause unnecessary wear. Avoid:

• Tight or enclosed areas where airflow is limited

• Directly under roof edges where snow, ice or water can fall on the unit

• Against fences, walls or dense vegetation that may block airflow

• Facing walkways, windows or parking areas where exhaust air may cause condensation or discomfort

• Exposed corners where wind may circulate cold exhaust air back into the unit

Optimal airflow around the outdoor unit is crucial for efficiency and quiet operation. Always ensure recommended clearance in front of the fan and around the sides.

Installation & Maintenance Considerations

To guarantee safe operation and long-term system performance:

• Mount the unit on a sturdy, level base or secure wall bracket to reduce vibration

• Ensure free airflow for both air intake and exhaust

• Provide clear access for annual servicing and inspection

• Avoid locations exposed to excessive moisture, snow accumulation or falling debris

• Use anti-vibration pads where necessary to minimise noise transmission

Correct installation helps the ADAPT, VERSI and ETERA systems operate quietly, efficiently and reliably throughout their lifetime.

Heat Pumps Designed to Blend In – Custom Colours Available

Kronoterm’s outdoor units are engineered not only for performance but also for aesthetics. The ADAPT and VERSI ranges, in particular, are available in multiple colour finishes, allowing it to match or complement the appearance of your home.

For homeowners wanting the perfect architectural fit, custom colours can be ordered — ensuring the heat pump becomes a natural part of the property’s exterior design rather than a visual distraction.
