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.
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.
