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.
Эта статья представляет собой практическое руководство по диагностике и закупке и не заменяет инструкции производителя насоса, утвержденный проект системы, действующие правила электромонтажников и сантехников или квалифицированное обслуживание на месте. Перед вскрытием оборудования отключите подачу энергии и сбросьте давление. Работы с колодцами, подъемные работы, работа в замкнутых пространствах, со сточными водами, во влажных электроустановках и испытания под напряжением требуют наличия компетентного персонала и средств контроля, соответствующих конкретным задачам.
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.

Границы системы, диагностика и приемка
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.
