Hydronics Unlocked Online

Stop guessing. Start understanding how systems really work

If you fit heating systems today, the job is changing.

It’s no longer just about fitting the boiler or the heat pump. How you design and set up the system matters just as much.

Good hydronic design is the difference between a smooth job and unforeseen problems, between low efficiency and high efficiency, between customer satisfaction and complaints.

Hydronics Unlocked Online

Hydronics Unlocked Online is our interactive training programme for heating engineers who want to design and fit systems that work properly, first time.

Built around real-world scenarios, it gives you the skills to reduce inefficiencies, avoid costly mistakes and deliver better results on every job.

Why this matters now

Condensing boilers and heat pumps only run efficiently when the system is right, but most heating engineers were never shown how systems work as a whole.

As a result, many struggle to diagnose common problems and often recommend the wrong fixes:

• bigger pump
• bigger boiler
• powerflush

This course helps you move beyond that, so you can see the system behind the symptoms, make the right call first time and design problems out before they cost you.

The practical tool the trade has been missing

Heating engineers have the right tools for every part of the job: cutting, bending, testing.

But when it comes to system design, there is no single tool. Just a collection of topics.

Hydronics Unlocked changes that.

We’ve developed a simple, repeatable 10-step process to good hydronic design that you can use on any job.

Designed in the order you actually work - survey, design and install - our 10 step process gives you a clear way to approach every system, time after time.

One approach for boilers and heat pumps

The heat source may change. The our 10 Step process doesn't.

This course gives you the understanding to work across both without having to relearn everything as the industry shifts.

From learning to doing

System training has traditionally been theory-led, which makes it hard to apply on site.

We’ve built this course around what you need to be able to do, focusing on the decisions you make on real jobs and the knowledge that supports them.

With interactive activities and simulators, you'll see how each decision affects performance and build the confidence to use it on your own jobs.

Built for working engineers

Training often means days off the job and knowledge that doesn’t stick.

This course is built around you and teaches through real scenarios you can apply on site, so you can upskill and excel in your career.

• Learn at your own pace
• Fit it around live jobs
• Revisit modules when you need them
• See how to apply it onsite
