Held evidence, joined carefully
Heat-pump comparison and reference data
These pages assemble exact model mappings, captured-manual specifications and dated brand research. They do not estimate prices, rank efficiency or fill gaps with a similar-looking product.
Published references
A controller page exists only where model-to-codeset evidence is already held. A tank band appears only after at least eight current models each clear the three-specification threshold.
Cross-brand comparison
Heat-pump warranties
21 completed brand warranty reviews, including honest unpublished-term outcomes.
Cross-brand comparison
