Build an Extreme Green Hot Water Solar Collector

Not for the " lay person ". Need an degree in heating engineering to make head nor tail of it.

Excellent read and fantastic idea havent been able one yet but hope to soon, very informative book mind

bon livre mais qui s'adresse surtout à des professionnels de la chaufferie qui pourront transformer une installation existante. bien sûr un amateur persévèrent y arrivera :p

I have a small head and this helmet fits perfectly.

This is an excellent book with clear and well thought out plans. With a little investment of time and the parts listed, you will have a worthy product that will save money and provide satisfaction.However, given that I don't have my computer next to my power saw etc, having a print edition would make it a lot easier to build. What about a way to at least print out the parts lists and pertinent diagrams? Naturally, printing an e-book is a bit backwards, but lets also be practical. I'm not about to haul my kindle or laptop to the shop or outside on the roof.A printable form of the plans would make it five stars.

Excellent. I have been studying alternative energy since 1979. Grassroots design and build. A system like this is $3000 to $4000 on Amazon. Just search for the hybrid hot water system and see. This can be fully completed under $800. Buy this book.

The recipient really enjoyed the book and stated it was just what he was looking for

Very informative.

If you just want to build this particular solar water heater, this book is great. Very little discussion of other possibilities of design variants.

Good detailed info - probably will build something similar.

if your a beginner, And have no idea of what you are doing this book will leed you on the right track..

Medium work

It's ok

I will say it did answer a few questions in my mind and I do intend to build a hot water version as well as a hot air version of a heating system.Everything I studied in the book was expensive. I have researched solar systems since 1973. I had just gotten my first electric bill for heating our new total electric home and it was over $300. Since then I have covered many systems and this one is way to expensive for my pocket book.

Good reference for those "DIYSers"!

Another good solar heating book, one that you should add to your collection for reference when needed.

For the right person I am sure this would be a good book. I am in Haiti so I don't need a heat exchanger. The collector won't freeze. I need a simpler system. I thought the diagrams looked helpful. It just wasn't.what I was looking for.
