Hydronics For Domestic Installations
Hydronics is hydronics be it ASHP or gas powered systems. It’s about getting the right amount of hot water to the right place at the right time at the right temperature, whilst keeping the correct Dt across the heat source. The same rules apply no matter what the heat source from bonfire to nuclear – once the energy is transferred into the water the laws of hydronics are the same. So, no matter which route you took to get here (ASHP or Gas Boilers) from here on its all the same only the numbers are different.
Over the course of two days, the agenda will include:
• Why Condensing boilers seldom condensate.
• Condensing mode is not an on / off switch.
• This free energy is here for the taking – so why don’t we?
• PDHW why it’s the way forward using two flow temperatures.
• The advantage NTC sensor-controlled cylinders.
• The need for modulating controls
• Basic flow and velocity requirements and how to size pipes pumps & radiators.
• Understanding the critical effect of DT on the system.
• The joy of the lightbulb moment when it all makes sense.
• Head & system resistance explained in simple words & units.
• Understanding pump maps/graphs and how to size pumps.
• What does your pump need to do? How do you choose it?
• How to configure the pump.
• Pumps in series.
• Managing large system / boiler flow mismatch issues.
• When and why to use close coupled T’s how they work and how to size them.
• Taking the taboo from low loss headers. It’s just another piece of pipe. How they work, when to use them, how to size them.
• Understanding why lots of UFH is incorrectly piped.
• Reverse returns – what’s that all about?
• Single pipe systems.
• Surveying for retrofit ASHP – no room for mistakes.
By the end of the day hopefully some old myths will be highlighted, hydronics will make a bit more sense and you will be able to increase Gas fired system efficiency with just a tweak or two. For ASHP you will be able to confidently determine what, and only what needs changing or upsizing Plus, design & commission better & bigger domestic systems. At the very least it will be an eye opener.
This is an informal two-day course for like-minded installers. There is no ‘pass mark’ nor qualification at the finish. It’s about how and why we do things now, moving on to why we need to look at leaving the old methods behind, plus continuing on to understand more about controlling hydronics to make our systems more efficient for no extra financial investment to the customer.
A) a lot of free energy out there that can be used if we commission our gas boiler systems correctly and
B) ensuring our system is able to cope with the much greater flows required by Heat Pumps.
PDHW with Pin 5 on the Intergas
Priority Domestic Hot Water (PDHW) for the Intergas boiler range, including multiple zoning and an introduction to open therm controls.
Agenda will include:
• Explanation of what pin 5 (PDHW) is, how pin 5 works and its advantages.
• Why S Y & W plans don’t condensate much.
• Fundamental differences of heating hot water in cylinders (Y plan against Pin5).
• Looking at Priority Hot water & why it’s the best way forward.
• What and how do NTC’s work. Evaluating the difference between NTC controlled heating and cylinder stat (on off) controlled heating.
• Confirming pin 5 applications are easier to wire than S & Y plans.
• Explanation of many multi zone systems utilising pin 5 and how to pipe them, wire them & control them using on off or Open Therm. All diagrams provided.
• How to set up combi’s with external cylinders & multizone on Open Therm or On / Off.
• How to make your own storage combi for high flow requirements.
•Turbocharging a combi for maximum hot water delivery
• Understanding Pump Maps/graphs and how to size pumps.
• Basic flow requirements & how to size pipes.
• Understanding hydronic separation & when & how to use it
• Taking the taboo from Low loss headers. It’s just another piece of pipe. When to use them & how to size them.
• When and why to use Close Coupled T’s & how to size them. • Realising why lots of UFH is incorrectly piped.
• Explanation to understand the Parameter settings & when to change them
This is an informal day for like-minded installers. There is no ‘pass mark’ nor qualification at the finish. It’s about how and why we do things now, moving on to why we need to look at leaving the old methods behind, plus continuing on to understand more about controlling hydronics to make our systems more efficient for no extra financial investment to the customer. PDHW (Pin 5) is really simple to wire and affordable to implement.
Control Electrics Y plan to Smart Phones
This course is currently not running.
This 1 day control electrrics training is to explain how compatible all the various types of controls work with modern heating. Including wiring techniques and fault finding from S/Y plans right up to the Open Therm smart type controls.

Fantastic course, the way kimbo delivers the information to you is as simply as it can be no hard maths or big numbers would highly recommend no matter what experience you have!!!
What a knowledgeable guy! I’ve learnt so much from kimbo today. Thank you for the training day
Brilliant day today loads to take in but really good. Thanks Kimbo
Just attended Kim’s course on Hydronics. Brilliant day and opened my eyes to a lot of ideas about new ways of looking at system design etc. Kim is enthusiastic throughout and keeps the subject interesting and easy to understand. Lovely location and the food was spot on. I’d recommend it to anyone in the industry.
Today I attended the domestic Hydronics course and couldn't recommend the heating acadamy highly enough.
My brain is aching after a full day but I really enjoyed it. There were so many light bulb moments, it will take some practice and time to sink.
The classroom is fine and refreshments were top notch too.
I'll definitely be looking to see if there are any other courses I could attend.
Domestic Hydronics course was an excellent, informative and thought provoking day. If you install domestic heating systems, you need to attend this course!
Really eye opening day and explained in an easy to digest way. Advanced maths tweaked for the common man which allowed us to be correctly sizing pipework, pumps, pump settings, headers and close couple t’s before lunch! With a few examples to work through and a refresher book to take home Kim puts you in the best position to actually remember and more importantly use the skills you learn. Highly recommended, with correct pump and pipe sizing you could save the cost of the course on your first install. Looking forward to jumping on the other courses when I see dates available.
Very friendly and informative, probably the best day of training i can remember in 35 years of doing this stuff. If you want to learn how to get the best from your boiler/ system, get yourself booked on.
Cracking day! Lovely company & food! Learnt lots about low lose headers, close coupled tees & pump sizing 👍🏻.
All knowledge and information you can take with you into the field 👍🏻
I'm wondering why I never contacted these guys sooner! Seriously, they all have commendable talent in tFantastic course, really informative.
Fantastic course, really informative.
I feel I've changed my perspective towards my jobs armed with this new knowledge. Good to see where I was going wrong (and right) on my past work.
