Paper presents new Partial Hybrid Compression Heat Transformer (PHCHT) heat pump, joining Partial Hybrid Compression and Heat Transformer in an Absorption (ATS) and Mechanical Compression (MVCTS) synergy. A lemma proves heating COP. PHCHT is modelled. Heat is produced and stored during night time for entire day use. ATS and MVCTS operate with ammonia-water and ammonia. 1st results hold for yearly household WWH of β‰ˆ 55oC for a selection of 36 cold and temperate climates. Ground water and air are heat and sink. Average temperatures come of weather channels, π‘‡β„Žπ‘  ∈ [6,5℃, 23,0℃] and π‘‡π‘›π‘–π‘”β„Žπ‘‘ π‘Žπ‘–π‘Ÿ ∈ [βˆ’3,5℃, +8,45℃]. COP is by (10 βˆ’ 120)% higher comparatively. 2nd results describe a typical cold night zone (Romania). Yearly COP is higher by ~ 150 % comparatively. Despite that PHCHT needs cca. twice more ground heat as
compared to MVC heat pump, results show PHCHT could bring important primary energy savings worlwide.
