Heat pump mounting: feet, ground stands, wall brackets or roof supports?

The four options

Option	Best for	Watch out for
Anti-vibration feet	Units on slabs, paving or flat roofs; quick installs	Enough height for condensate drainage and snow
Ground stands	Snow regions, wet ground, where clearance below the unit is required	Stability and anchoring in exposed sites
Wall brackets	Tight sites; units the manufacturer permits on walls	Wall strength, anchors, vibration transfer to the building
Roof supports	Flat roofs without membrane penetration	Membrane compatibility, wind exposure, load spread

Vibration and noise

Heat pumps run for long periods, often near bedrooms. Rubber elements between unit and structure reduce structure-borne vibration — the reason rubber feet or pads are included with most stands and brackets. Airborne noise is a separate question of unit choice and siting.

Load and data

Published loads vary widely: for example one popular recycled-rubber foot is rated at 450 kg per foot, while wall brackets are typically rated up to around 200 kg. Always size against the unit’s operating weight and the manufacturer’s tested figure — not the largest number in a catalogue.

Building a range

A wholesaler range that covers most installs needs 2–3 lengths of feet, a plastic and a galvanised stand, a standard and a heavy-duty bracket, and one roof-support family — packed consistently under one label.
