Principles & operation

  1. Heat-pump cycle, COP and system modesHow the vapour-compression cycle moves heat, why temperatures affect COP, and what monovalent and bivalent systems mean.

Components

  1. Heat-pump components and their jobsTrace energy and flow through the refrigerant, hydraulic and control components of an air-source heat-pump system.

Standards & regulations

  1. Heat-pump standards, planning and competenceSeparate design standards, Building Regulations, planning, electrical duties and refrigerant competence.

Design & sizing

  1. Heat pump design — the essentialsWhy heat pumps are designed around low flow temperatures, heat loss and bigger emitters.

Installation

  1. Air-source heat-pump installation checksA practical sequence for siting, water-side preparation, condensate, electrical provision, commissioning and handover.

Service & maintenance

  1. Heat-pump service and maintenance diagnosisA measured maintenance sequence covering airflow, water flow, condensate, antifreeze, controls and the refrigerant boundary.

Revise the heat pump and the heating system together

Trace how heat moves through the refrigeration cycle, then connect the heat pump to the building demand, emitters and controls. For a design scenario, identify the operating conditions behind a quoted output or efficiency figure before comparing options.

Use the radiator output calculator to explore lower-temperature emitter performance and the Level 3 heating notes for design principles. The F-Gas notes cover the separate refrigerant-handling subjects where they apply, and the F-Gas certification guide explains where a monobloc installation ends and certified refrigerant work begins.
