Heat-pump electricity use equals its average electrical input multiplied by runtime, plus auxiliary heat, fans, pumps, crankcase heaters, and controls. It varies with weather, building heat loss or gain, equipment size and efficiency, thermostat settings, defrost, airflow, duct or water-loop condition, and electricity tariff. Use interval meter data and equipment records over comparable weather. A nameplate maximum or one instantaneous reading does not predict a monthly bill, and auxiliary resistance heat can materially change consumption. The reliable answer comes from the exact model, actual operating conditions, and an approved test rather than a universal shortcut.
Cet article est un guide pratique de diagnostic et d'achat, et ne remplace pas les instructions du fabricant de la pompe, une conception de système approuvée, les règles actuelles en matière d'électricité et de plomberie, ni une intervention qualifiée sur site. Isolez l'énergie et la pression avant d'ouvrir l'équipement. Les travaux de puits, de levage, en espaces confinés, les eaux usées, les emplacements électriques humides et les essais sous tension nécessitent un personnel compétent et des contrôles spécifiques à la tâche.
List every electrical load
List every electrical load. Begin with the exact product, system, and operating condition rather than a generic assumption. For how much electricity does a heat pump use, document the model, configuration, symptoms or objective, recent changes, and the instructions that control the work. Check the relevant supply, connections, controls, flow path, surrounding equipment, and environmental conditions in a safe sequence. Do not treat one observation as proof: compare it with a second measurement or an approved functional test. If the task exposes electricity, pressure, fuel, refrigerant, hot surfaces, contamination, moving machinery, or a vehicle safety system, stop and use qualified service. After any adjustment, restore guards and automatic protection, then repeat the same test and record the result. This makes the list every electrical load decision reproducible instead of relying on memory or trial and error.
Separate power from energy
Separate power from energy. Begin with the exact product, system, and operating condition rather than a generic assumption.

Limites du système, diagnostic et réception
A heat pump is a refrigeration system, not simply a water pump. It moves heat by circulating refrigerant through a compressor, heat exchangers, expansion device, and reversing or control components. Electrical power use and operating behavior depend on outdoor and indoor temperature, building load, equipment capacity, efficiency, airflow or water flow, thermostat settings, auxiliary heat, defrost, installation, and maintenance. Nameplate ratings and standardized efficiency values do not by themselves predict one home's bill.
Refrigerant circuits are sealed, pressurized systems. Refrigerant identification, charging, recovery, leak repair, electrical testing, and component replacement require the approved equipment and appropriately qualified personnel. Do not vent refrigerant, heat a cylinder, open service valves, or defeat pressure, temperature, airflow, or defrost protection. A frozen coil, high bill, noise, or poor comfort can arise from airflow, filters, outdoor blockage, drainage, controls, sensors, duct or hydronic problems, weather, or building heat loss—not only refrigerant charge.
Useful records include model and serial numbers, system type, thermostat settings, outdoor and indoor temperatures, runtime, auxiliary-heat indication, filter and coil condition, airflow, condensate drainage, electrical consumption, service history, and fault codes. Compare similar weather periods. After service, verify stable heating and cooling, normal defrost, drainage, airflow, sound, protection, and documented refrigerant handling.
