Hydronics Unlocked Online

Confidently design and install high performing heating systems

Hydronics Unlocked Online equips heating engineers with the skills they need to design and install modern systems.

Built to stick - the course uses short, practical modules that show how to apply what you've learnt when surveying, designing and installing real systems.

The same approach works for both boilers and heat pumps, helping engineers upskill now and transition confidently to heat pumps.

Why this matters now

For years, rule-of-thumb practices worked because high flow temperatures hid poor system design.

That safety margin is disappearing.

Condensing boilers and low-temperature heat pumps rely on correct flow, resistance and circulation to perform properly, yet most engineers were never taught how heating systems actually behave or how design choices affect efficiency and bills.

When design falls short, the problems show up fast: 

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

Hydronics Unlocked focuses on fixing those decisions before they cost time, money and confidence.

The same design rules apply to boilers and heat pumps

While boilers and heat pumps use different appliances, the way the system is surveyed, designed and installed is largely the same.

Pipe sizing, flow rates, emitter output, pump capability and control setup determine whether a system works properly, regardless of the heat source.

Hydronics Unlocked teaches one clear approach engineers can use on boilers today and heat pumps tomorrow, without having to relearn system design from scratch.

Learning that isn't boring

Hydronics Unlocked Online is built by engineers, for engineers, designed the way engineers actually like to learn.

• Short, focused modules that are visual and get straight to the point.
• You’re involved in the learning, not just watching.
• Everything links back to real jobs and real design decisions.
• Learn by doing, not just reading or listening.

What Hydronics Unlocked Online will give you

Unlike courses that front-load theory, Hydronics Unlocked introduces theory when it’s needed, then shows how to apply it on site.

Rather than isolated topics, the programme follows Warmur Academy’s 10-Step process, built around how engineers already approach surveying, designing and installing a heating system.

As engineers move through the steps, they’re applying the theory to a real home, seeing how each decision affects the next and building a complete system design they can repeat on site.

That’s what turns learning into something practical and makes it stick.

From proven classroom training to flexible online learning

Until now, Hydronics Unlocked has been delivered as a one-day, in-person course.

With Ideal Heating’s support as a founding partner, the programme is now being expanded into an interactive digital learning platform, allowing engineers to:

• Learn wherever they are in the UK
• Progress at their own pace in bite-size modules
• Revisit concepts when they need them on real jobs
• Build confidence in modern system design over time
• Get a recognised low temperature qualification at the end

The online course is designed to build our one 1-day introductory course we'll you'll get interactive with system design.
