The Awakening and Mastery course combo

£730.00 ex VAT

Heat Geek Heating Mastery is an online training course focusing on heating design and controls in the heating industry. Heating Mastery is broken up into two smaller courses, ‘The Awakening’ which teaches the fundamentals of heating design and ‘Mastery’ which goes deeper into hydronic understanding and theory, which will be released imminently.

Requirements: Facebook group access for peer to peer interaction.

The Awakening 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 describe some of the terms and measurements used within the industry and this course. An essential starting point.

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 and how we measure and calculate velocity.
The velocity triangle

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

The Mastery course covers:


1. Emitters Mastery

Techniques for emitter upsizing and working off a reference room, for different emitters including rads, underfloor heating and fan convectors, also the benefits of each type for heat pumps and any other heat source or property. A deep dive into underfloor heating, including how to size it, benefits of different pipe layouts, the different 5 variables that allow different flow temperatures, various conversion factors for insulation upgrades and floor outputs.

2. Controls Mastery

A high level module on controls for all heat sources but with a focus on heat pumps including underfloor heating valves and controls, variable temperature mixer valves and controls- when they’re needed, how they work and how they’re controlled. Hysteresis and dynamic cycling, how these can be fine-tuned to maximise efficiency and comfort on any system. Closed-loop vs open-loop control, when to close the loop and how best to close the loop. Why zoning is not a good idea in many cases, when and where to zone. Calculating different heat pump COPs with different control strategies.

3. Hydraulic Separation

What hydraulic separation is, when and where to use it, the 4 forms of hydraulic separation, how to size orientate and install low loss headers, how to size orientate and install close-coupled tees, distortion – what it is, how to calculate it and minimise it, plate heat exchangers – the different types, how to size them with both log mean temperature and arithmetic mean temperature, where, when and how to install them. Round up of when and where to use different types.

4. Buffers

A two part module describing what a buffer is, when and where to use them with rule of thumb, the 3 variables used when sizing them if not using rule of thumb with worked examples.

5. Buffer Mastery

Different pipework orientations and benefits to each one in each flow situation and each differential temperature situation helping with design, fault finding, commissioning of systems and tweaking for efficiency upgrades.

6. Efficient Hot Water Production

How to size in relation to power and demand rather than volume, how to maximise efficiency during hot water production, the effects of running different heat exchangers at different flow rates and temperatures, what the heat source saturation point is and how we can use this for sizing.
