Design and installation in one course — from the heat loss calculation right through to balancing the loops and handing it over.
Everything the course covers, module by module.
→ Why underfloor runs low and slow, and where it beats radiators
→ Solid screed, suspended timber and floating floors — and what each one asks of you
→ Floor coverings: tog ratings, contact temperatures and the finishes that kill output
→ Manifolds, blending valves, actuators and wiring centres, part by part
→ The design maths worked right through a real house — pipe quantity, coil length, flow rates and floor surface temperatures
→ Pipe layouts, centres and circuit lengths that actually work on site
→ Pressure testing before the screed, the heat-up curve, balancing and fault finding
The interactive half of the course is open to everyone, no account needed. Identify a floor construction from its section, work out whether a carpet and underlay will still let the floor deliver, label a manifold and follow the water through it, size the pipe and the flow rates on a real bungalow, then find out honestly which rooms the design does not reach — and diagnose five callouts, one of which turns out not to be a fault at all.
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.

Both. The trade normally splits underfloor heating into two certificates, but the two halves only make sense together — you cannot lay a circuit properly without knowing why it was drawn that way. This course runs the whole thing end to end.
No. The design calculations are worked step by step through one real house, and you can do every one of them on a phone calculator.
