Hydronics Unlocked Online

Confidently design and install high performing heating systems

Learn how to design and install heating systems that actually work on every job

Hydronics Unlocked Online is Warmur Academy’s digital training programme for heating engineers who want to confidently design modern heating systems, including heat pumps.

Built around real world system design, the course gives you a clear, repeatable method you can use on site, not just theory to remember.

A practical way to learn heating systems

Hydronics Unlocked is structured around how engineers actually work: survey, design, install and commission.

You don’t learn theory in isolation. You learn it at the point you need it and immediately apply it to real system decisions.

This makes it easier to understand, easier to retain and easier to use on your next job.

Built for real systems, not classrooms

The course focuses on the decisions that determine whether a system works properly

• Pipe sizing
• Flow rates
• Resistance
• Pump capability
• Controls

All delivered through:

• Short, focused modules
• Clear visual explanations
• Interactive learning

This isn’t passive learning. It’s training you can use immediately in the field.

Why this matters now

Traditional systems were more forgiving. High flow temperatures often masked poor design.

Modern systems, especially heat pumps, are different.

They depend on getting the fundamentals right

• Correct flow
• Managed resistance

When these are wrong, issues show up quickly

• Cycling
• Cold rooms
• High running costs
• Call backs

Hydronics Unlocked is designed to help you get these decisions right first time.

One approach for boilers and heat pumps

The appliance may change. The system design principles don’t.

The same fundamentals determine performance across all systems.

This course teaches a single, consistent method you can apply

• On boilers today
• On heat pumps tomorrow

No relearning. No starting again.

From learning to doing

Rather than covering isolated topics, the course follows a full system from start to finish.

As you move through the 10 step framework, you will

• Apply theory to a real home
• Understand how each decision affects performance
• Build a complete system design you can repeat

This is what turns knowledge into confidence.

Learn in a way that fits your work

Hydronics Unlocked Online is designed to work around your day to day jobs

• Learn anywhere in the UK
• Progress at your own pace
• Revisit modules on live projects
• Build confidence over time

The programme also supports progression towards recognised low temperature system competence.
