Placement Tips For An Air-Source Heat Pump

An air-source heat pump has indoor and outdoor units that work together to cool and heat the house, depending on the season. The outdoor unit's location affects its efficiency, installation budget, and your comfort. Here are a few tips for choosing a suitable location.  

Place It on a Flat Surface

The heat pump unit works best in an upright position. Choose a flat-surface location for the unit. However, the ground doesn't have to be naturally flat – you can flatten it or build a flat structure for the placement. Ensure any platform you construct is sturdy enough to hold the unit's weight without damage. Concrete platforms work well enough.

Ensure Adequate Airflow

The outside unit of an air-source heat pump absorbs heat during the cold season (there is always some warmth in the air). The refrigerant then flows into the house and releases the heat to warm the house. The inside unit absorbs heat and disperses it outside during the cold season. Thus, air circulation around the unit is mandatory, irrespective of the season.

Choose a location that encourages efficient airflow. For example, don't sandwich the unit between the wall and a fence, allow tall plants to crowd it, or confine it inside a built structure. If you must protect the unit, ensure adequate clearance between it and the protective material.

Target Convenient Electrical Connections

The heat pump uses electricity to work its fans and motors to circulate air and keep the refrigerant moving. Therefore, the ideal location should allow easy electrical connection to the heat pump. Although you can always extend electrical connections, short ones are typically safer and more affordable.

Avoid Exposure to Corrosive Substances

The outside heat pump unit is mostly metal, and metal is susceptible to corrosion. For example, corrosion can damage the refrigerant lines and cause leakage. Corrosion can also damage the unit's coil and dampen heat exchange.

Don't place the unit where corrosive gases or liquids will affect it. For example, corrosive exhaust fumes might damage the unit if you place it where you park. In such a case, the car's fumes will affect the unit whenever the engine runs.

Mind the Operating Noises

Lastly, expect the unit to make a little noise every time it's running. Placing the unit on vibration pads will dampen some of the noise. However, you might still hear some sounds if you are too close to the unit. For example, installing the heat pump next to your home office's window is not a good idea if you mind the noise.
