Khalim Conn-Kowlessar bf240e3315 ASHP sizing targets the Appendix-N efficiency peak (realistic installed pump) 🟩 ... Sizing selects the aroTHERM plus rung nearest PSR ~0.8 (0.8 x design heat loss) — the Appendix-N efficiency peak, reproducing the pump a real installer fits — rather than the MCS PSR>=1.0 capacity target, which oversizes. Validated against the relodged Elmhurst ASHP cert (delta 0 held at the 5 kW Vaillant); the two self-snapshot pins re-pin to their correctly-sized larger pumps, and the orchestrator/harness thread the calculator's design heat loss so production sizes to the dwelling. Manual SapResult test stubs carry the new design_heat_loss_kw field. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>		2026-07-03 11:02:13 +00:00
