The Awakening

Modern system design for heating and renewables in commercial and domestic buildings – Part 1

🚫 You are not yet enrolled in this course.


The Course

Heat Geek’s “The Awakening” is the first half of an online training course focusing on heating design and controls in the heating industry and teaches the fundamentals of heating design. The specific aim is to give real-world usable information and practices in a simple to understand way and cut out unnecessary jargon, enabling you to install more efficient systems, move into renewables such as heat pumps and also move into commercial heating.

The course usually takes between 20 and 40 hours. Access will be given for a limited time only of 6 months, but this can be extended for one further month, however only if requested prior to the original expiry date. During this time you will build an ultimate reference folder for you to refer back to long term throughout your career.

Beware – This course is not the same as typical industry ‘tick box’ courses. We push you hard in our training to become a heating master and you will need to put time and effort in to complete the course. But no matter where you are in your journey, as long as you watch the videos a few times, put in the time, and importantly engage in the peer-to-peer platform as much as possible you will become a true master.

This training is essential before moving on to the Mastery course.

This Course Covers:


1. Watt is energy?

What are Joules? What exactly are Kilowatts? How do they apply to thermal energy and what is Delta T?

This section highlights the difference between power and energy and frames how we are going to measure the energy we are trying to create, store, and distribute. As well as description of some of the terms and measurements used within the industry and this course

2. Heat loss

R-values, K-values, U-values. What these are and how we use these to calculate the thermal energy required for a building. An essential part of the two-part method of creating a low temperature system.

• How much ventilation is required for each room and what this means for heat loss.
• What happens to heat loss throughout the year
• Basic rules of thumb for quotations and calculations on the fly.

3. Mass flow rate

This introduces and explores the holy grail of heating, mass flow rate which is the relationship between flow and energy including:

• Specific heat capacity of water
• Magic Mo’s triangle

4. Velocity pipe sizing

What the difference between flow rate and velocity is how we measure and calculate velocity

The velocity triangle

• Pipe sizing
• Velocity, what is it and what it means and how to calculate
• Magic triangle

5. Pipe sizing, Pressure loss, and pump sizing

Pipe sizing, a brief overview of pressure losses, and how to calculate pump head requirements, system resistances, residual head graphs.

• Pressure loss
• Turbulent and laminar flow
• System resistance
• Index circuit
• Pump curves
• Residual head
• System curves

Round up

6. Emitter sizing

How to size your emitters (radiators) and the relevance to over or under sizing. The relevance of power and temperature.

• MW-AT-DT – What is it and where do I use it?
• Quick hand adjusters

7. Controls

What are we controlling and what are the variables that mean we need controls? What’s wrong with older methods of ‘on/off controls?

What You Get

24-Hour Access

Our course is online and pre-recorded, and you’ll have support from the peer-to-peer group 24-hours a day, which can be accessed at any time day or night to complete in YOUR time, not when best suits us.

7 In-depth Training Modules

Access to 7 in-depth training modules with videos and questions specifically structured to encourage a full understanding of the content, not just memorisation of the numbers!

The questions have been designed not to test your memory of what has been said in the training videos, but to use the information in real-world scenarios. This also forces you over to our peer-to-peer support platform to engage with other engineers, which has been scientifically proven to be the best way to learn new information.

Industry-leading Workbooks

This is your opportunity to begin your lifelong reference book for anything in heating design.  The layout encourages you to cover all aspects required and gives a base for you to build on and add to with your own research if and when required.

Unlimited Peer Support

Access to unlimited support from other engineers for each phase of the course in our support groups.  Other engineers, system designers, policy makers, and enthusiasts are also pushed to use the groups providing a wider perspective from lots of different backgrounds.

100% Online - Complete in Your Own Time

The entire course is online and accessible from our courses website at any time of the day so you can complete it around your work hours. Simply log in and continue where you left off.

Heat Geek Branding License
