The 9th edition has now been on the shelves (well on Amazon's shelf at least) for just over a month and is selling well. And signs are that it's getting read as well because two eagle-eyed readers have spotted the fact that in Chapter 8 (Plumbing & Heating) I refer in the text to a table that isn't there. I can only apologise: it somehow got lost in the changeover between editions. The reason is that the 9th edition features a benchmark house without a conventional heating system and so there are no conventional heating costs to table. But I didn't mean to leave out the conventional heating costs - they just got overlooked.
So for readers scratching their heads, here is the data that should have been in Chapter 8.

The new edition is also significant for its lack of proof-reading & editing: large numbers of spelling mistakes, typos, missing words, 2 words run into 1, index page numbers not matching up with text etc. I suspect it was a rush job to get it printed in time for the NEC show...
ReplyDeleteHey john,
ReplyDeleteYou got the mistakes very well. I agree with you.
Well at least the plumbers rates are reasonable lol...
ReplyDeleteI wanted to say the same you had said. Thanks for that. My some boilers were getting problem than thought to have repaired and some commercial boiler repair engineers help me a lot and solved the issue very well. I really don't care of price matter if it's all about quality work.
