Student reviews

pay attention & learn as much as possible because these courses are worth their weight in gold

The course is very much useful

It's pretty hard to be able to be an HVAC contractor and properly design systems for customers in the 21st century if you didn't take and learn physics in high school. At least the basic science underlying the principles of hydraulics and thermodynamics - and maybe electricity and chemistry. But with or even without that basic education, Siegenthaler's courses, books, articles, and lectures in hydronics can help you become fully and proudly competent and ready for the future as well as the present.

This was an extraordinary free course!! I am a crusty, seasoned mechanical engineer who'd only been occasionally involved in the details of this facet of mechanical engineering since my undergraduate days. John Seigenthaler taught me more in this short, detailed, free course (or reminded me of stuff I'd forgotten) than I thought was possible -- wow!! I've been designing a retrofit of a totally new heating system for our off-grid home with the aim of achieving the holy grail of a net-zero, off grid, 100% solar/wind property. John's short lecture (and the follow-on Q&A recording) have sent me back to square one on my designs, and I now believe I can make it possible. I ordered John's book "Heating with Renewable Energy", and I'm looking forward to learning more. I also hope to be able to squeeze in the time to take his Modern Hydronic Heating course even though I'm not a building and heating pro. John is, by far, the best presenter I have encountered on heatspring; spend two hours of your time listening to what he has to say! If they ever charge for this course--pay the fee! -Brad Wall, Connecticut.

YES

excellent course for new hydronic Designers

Today, the water heating system is becoming increasingly popular and engineers must learn it

Spend the time take the course. I will get you to think outside the box

For just two hours of a day , this course gives all you need to design efficient heating systems

t

Super informative design ideas for low temp systems. Very good explanation and reasoning for designing lower temp heat emitters.

yes

GOOD

I would recommend for my students

The course is beneficiary.I would recommend to my research scholars.

I would highly recommend this course for all system designers that have been in the industry for a long time. The concepts and applications of utilizing low water temperatures gives the designer so many other options on heat sources. This was a great learning experience.

Keep learning

John is the authority on this subject...incredible knowledge on all related aspects of radiant heating...

Helpful course. I am considering taking some of the others now.
