Grouped by roughly the size heat pump your home might actually need. That way you compare brands directly at that size, not by brand — nobody's really choosing between their own small and large model. Matched by real heating capacity, not just the labelled kW. Fan positions are approximate. A 6ft ruler mark sits at the end of each row; scroll sideways on a narrow screen.

Tiers group models with roughly similar real-world heating output, not identical labelled kW. The exact size your home needs depends on a proper heat-loss survey, not this page. Widths shown are the unit's front-facing width; depths aren't shown in this front-on view. Figures come from each manufacturer's published specifications and may vary by exact model or revision — always confirm with your installer. This is a size and shape comparison only, not an endorsement of any brand.
