ᐅ Distance Between House Wall and Air-to-Water Heat Pump

Hello everyone,

Is there an official standard specifying the minimum distance between the outdoor unit of an air-to-water heat pump and the exterior wall of a house? A pedestrian who saw our air-to-water heat pump said the distance should always be at least 50 cm (20 inches), regardless of the model. Is that correct? Is there a way to look this up?

Best regards,
Oliver

Hello,

the distance from the wall is specified by the manufacturer and should be indicated in the installation or user manual. Due to the design, these distances vary depending on how the manufacturer has planned the air intake. For my future Panasonic air-to-water heat pump, a minimum distance of 30cm (12 inches) from the wall is required.

As far as I know, the pedestrian is mistaken. Why? I believe that the distance is always determined individually by the manufacturer (they usually conduct additional tests for this), so the minimum distance can be less than 50cm (20 inches) depending on the model 😉 I hope I was able to help you 😀
