Graham Hendra’s e-book is out on Kindle
For those that are interested, I’ve just seen that Graham Hendra has published a book, 50 things you need to know about heat pumps: A simple guide to renewable heating, but you didn’t know who to ask, which is available as an e-book on Amazon.

Will do….
I’ve got a lot of time for GH and happy to support his efforts to grow this industry. If I can do that by purchasing his book (it’s unlikely I’ll purchase a HP from him 😂) then that’s what I’ll do.

thanks to everyone who's bought my book, if its successful I will publish part two which is a bit more hi level for engineers. A few people dont want to line Jeff Bezos pockets so you can also buy it here https://graham-hendra.sumupstore.com/
thanks in advance and let me know what you think.
@hughf my days of selling heat pumps are alongway in the past, these days i just sell advice. but thanks for the nice comments i appreciate them.

I'd certainly be interested in a part2 - I've got JCs book on the subject and it's also informative.
I've spent hours in your masterpiece of a spreadsheet, sizing my system and playing with rad options, buying your book is the least I can do to say thanks.

I generally buy kindle books these days, my close up eyesight isn't as good as it used to be, so I find it easier to read. I also appreciate not having to build yet another shelf.
I haven't got a kindle either, I use the free kindle app for the ipad. There's a free kindle app for PC and mac too.

Thanks for the share @Editor - I've just bought the book for Kindle. Looks great!
Also, thanks for the intro to Graham Hendra's work which I've just been consuming. Graham looks like an ideal expert to help me with my own ASHP questions!
