Heat pump electrics: the electrical work
Installation · Full course section in Plus
A heat pump transfers heat using electrical input. Its advertised thermal output is not its electrical demand. Supply assessment needs the actual input ratings, operating conditions and any auxiliary electric heaters, alongside the building’s other loads.
The electrical design coordinates circuit protection, isolation, controls and manufacturer requirements. Refrigerant work belongs with an appropriately qualified specialist, including company certification where required. Heating-system and water-side design need their own relevant competence.
Planning, building requirements, network connection and funding eligibility are separate enquiries. Check the nation, building and scheme conditions before making promises. Participation in an installation certification scheme does not itself grant planning permission.
The environmental-technologies unit teaches the electrical interfaces. The future low-carbon electrical course is planned to develop the specialist subject further; it is not yet available.

What to understand before practising
The electrical supply is one interface in a heat-pump project. Confirm who owns the refrigerant work, water-side design and commissioning responsibilities before work is planned. Relevant F-gas work can require both individual qualifications and company certification.

Common questions
- Can I try Heat pump electrics: the electrical work free on this page?
- This guide is free to read, but there is no public quiz specifically for this topic on this page. Browse public practice samples for other subjects, or create an account for the learning path. The full course section requires Plus.
- Can the thermal output be used as the supply load?
- No. Use the equipment’s electrical input and applicable maximum-demand information, including auxiliary heaters where relevant.
- Does an electrical qualification cover every heat-pump task?
- No. Electrical, refrigerant and heating-system responsibilities have different requirements. Use the appropriately qualified specialists.

Maximum demand
The assessed greatest simultaneous demand of an installation or part of it. Connected loads, their operating patterns and justified diversity allowances inform the assessment. It helps determine supply and distribution capacity; it is not a guarantee that actual demand can never be higher, and a change of use may require reassessment.

The share of input energy or power that becomes the intended useful output, usually written as a percentage. Losses such as heat mean a real transformer or motor delivers less useful power than it takes in. Efficiency compares input with output; it is different from power factor, which compares real and apparent power in an AC circuit.
