Central Heating Wiring Course
Stop being nervous about the wiring side of a heating job. Wire up any S-plan or Y-plan system from scratch and fault find it when it goes wrong.
SPEC 01 / WHAT YOU'LL LEARN
Real skills. Real jobs.
- Read any heating system wiring diagram with confidence
- Wire up an S-plan or Y-plan system from scratch
- Understand what every terminal on a programmer actually does
- Fault find electrical issues without guessing or calling someone else
- Wire zone valves, room stats, and cylinder stats correctly
- Never sub-contract the wiring side of a job out again
SPEC 02 / COURSE CONTENTS
Every module, explained.

SPEC 03 / WHO IT'S FOR
Built for
working engineers.
01
Heating engineers nervous about electrics
You're confident with the pipework but the wiring side makes you uneasy. You've been guessing or just copying existing wiring. This ends that.
02
Plumbers avoiding wiring jobs
Every time a customer asks you to replace the programmer or the thermostat, you're sending them to someone else. Stop giving that money away.
03
Engineers sub-contracting the electrics out
It's costing you margin and job time. Most heating electrics don't require an electrician — they require an engineer who understands controls.
SPEC 04 / THE INSTRUCTOR
Written by a Gas Safe engineer.
Not a course factory.
10+ years on the tools across plumbing and heating. Everything in here comes from real jobs — faults I've diagnosed, systems I've wired, customers I've had to explain things to at 7am in January. No filler, no padding. Just what you actually need to know.

Finally understood S-plan and Y-plan wiring properly. The diagrams are dead clear. Watched it twice before my practical assessment.

Every time I had a wiring problem I'd end up lost on forums. This course sorted it out once and for all. The fault-finding section alone was worth the price.

Straightforward, no filler. Covered the exact systems I come across every day. Recommended it to two other lads in my firm already.

I've been avoiding wiring jobs for two years because I wasn't confident. Watched this on a Sunday and went and wired a full S-plan system on Monday. Job done.

The diagrams are exactly what I needed. Not just what goes where but why. That's what makes the difference when something goes wrong on a job.

My fault-finding used to take ages because I didn't fully understand the wiring logic. After this course it's completely different. Takes me half the time on a problem job now.

Bought this to help with a tricky job I kept putting off. Clear, concise, well put together. Exactly what you'd want from someone who actually works in the industry.

Used to dread any job that involved the wiring side. Watched this and now I actually feel confident. Brilliant course for the price.

SPEC 05 / FAQ
Questions,
answered.
Do I need an electrical qualification?
+
No. Heating controls and wiring (low-voltage thermostats, zone valves, programmers) don't require Part P notification or an electrical qualification. This is firmly within the scope of a Gas Safe or heating engineer.
How do I access the course?
+
Instant access to Vimeo-hosted videos via an emailed link after purchase. Watch on any device at your own pace.
I already know the basics — is this too simple?
+
If you can already wire an S-plan from memory and confidently fault find zone valve issues with a multimeter, probably yes. If you're looking anything up or still unsure about end-switch wiring, it's worth it.
Does it cover underfloor heating or renewables?
+
Not in this course. It focuses specifically on standard central heating controls — wet radiator systems, cylinder circuits, programmers, and zone valves.
