If you're replacing a steam boiler, there's only one right way to size that boiler, and that's to measure the radiators. If you're replacing a hot-water boiler, you'll do a heat-loss calculation on the building as it is today, but it also pays to measure the radiation to see if you can reduce the water's temperature and save fuel. The challenge, though, is that it's often difficult to find the ratings for many of those old radiators and convec...

Most of America's classic hydronic systems are older than we are, and they've gone through changes over the years, some of them painful changes. Many of these systems went in before we knew as much as we know today about hot-water heating. So let's talk about how Classic Hydronic systems work, how they've changed over the years, and what we can do right now to get the most out of them without spending a fortune. (Oh, and I promise you a few gr...

I was fortunate to have had the late, great Gil Carlson as one of my teachers. He invented primary-secondary pumping in the early '50s and went on to do many other things. Over the years, I've watched a lot of trial and error with primary-secondary heating systems. That's a shame because guesswork costs both time and money. In this book, I've used what Gil taught me to show you how to reduce the size of your pipes, valves, fittings and pumps, ...

When it comes to saving money on heating, old steam systems are delicious, low-hanging fruit. There is so much you can do to make them better, and most of what you can do won't cost a fortune. It's not that easy, inexpensive, or even practical to rip out an old steam system and start anew, and that's why so many of them are still around. In this book, I'm going to walk you through those old systems, tell you some great success stories, and sho...

I wrote this book to describe the beautiful workings of hydronic heating systems and I tried to use words that made the subject spring to life in a visual way. It's been one of my best-selling books for years. I kept the drawings simple. Even if you've never worked with hydronics before, you'll be able to follow these drawings. The first part deals with boiler-room piping and explains how you can put the discoveries of the late, great Gil Carl...
