Air and ground source heat pumps for working engineers — how they move heat, how systems are designed and sized, and how they're commissioned and fault-found.
Built for plumbers and heating engineers moving into heat pumps — whether you're working towards a qualification or already installing and want the design and commissioning detail straight.
✓ You're working towards a heat pump qualification.
✓ You want flow temperatures, lift and efficiency to actually make sense.
✓ You'd like the calculations — heat loss, flow rate, collector sizing — to stick.
✓ You want to diagnose a fault by reasoning, not by swapping parts.
Forty-seven lessons across seven modules, from the principles right through to diagnosing a fault on a system already installed — with a quiz, flashcards and short-answer check on each.
How a heat pump moves heat rather than making it, the refrigerant cycle, defrost, and what COP, SCOP and SPF actually mean.
Heat loss, flow rates and temperature difference, pumps and duty points, emitters at low temperature, buffers and cylinders.
Building Regulations, MCS and standards, planning and permitted development, Water Regs, the DNO, F-Gas and health and safety.
The pre-installation checklist, selecting a unit from manufacturer's data, ground array sizing, siting and noise.
Bases and clearances, barrier pipe and insulation, penetrations, collector installation, the brine circuit and safe isolation.
Cleaning and water treatment, filling and testing, setting flow rate and the weather compensation curve, records and handover.
A method rather than a fault list — routine servicing, water-side and source-side diagnosis, and refrigerant leaks.
Twelve hands-on tasks built into the lessons, alongside quizzes, flashcards and AI-marked short answers.
Twelve hands-on tasks are live and open to everyone, no account needed. Read a pump curve, size a ground collector, set a weather compensation curve and see what a bad one costs, work a fault from the symptom, and practise safe isolation on both a fuse and an MCB.
One in-depth article per module of this course, free to read, each ending in a 10-question mock test. They cover the same ground as the lessons, so you can see exactly what the course teaches before you buy it.

Air and ground source heat pumps end to end: principles and the refrigerant cycle, system design and sizing, regulations and planning, survey and pre-installation, installation practice, commissioning and handover, and fault finding — 47 lessons across seven modules.
Sixty days from the moment you buy — time to learn it, revise it and go back over anything that hasn't stuck.

It's written around the knowledge assessed in Level 3 heat pump qualifications covering the design, installation, commissioning and maintenance of air and ground source systems. It's learning and revision support, not a substitute for your training course or assessment.
Yes — the gas ACS reassessment, unvented hot water and Water Regulations courses are live now, and the full suite unlocks everything for a year at £59.99.
