What factors do you consider before putting antifreeze into a hydronic system and how do you go about doing it? If you'd like to play (and get the the list for free when we're done), EMAIL me your thoughts. Please don't post them here because I may miss them. Thanks.

you can put on a 1/2" line and still expect decent temperature near the end is 25'(of element). How much of this loop is element?

It's a cozy club with great sound. Here's a link: http://www.iridiumjazzclub.com/

Les Paul last night in a little jazz club in NYC. He's 87 years old but you'd never know it. Kind of special sitting and listening to the man who invented the electric guitar and multi-channel recording. He plays every Monday night in the same place and he's backed by an amazing trio. Well worth the trip.

@ September 23, 2002 9:26 AM in An old house revisited - Dan H.

to let Ed Bratton restore the old system. The house was ripped apart when I got there. They were jacking up parts of it and installing new beams. There were holes everwhere. I took some photos but I need to get them developed. I'll scan them and post soon. The place was quite a mess!

I was up to visit the Best Western this week

and I learned that Boston Tours runs just that, and that they pick up and drop off at the hotel in Marlboro. Here's a link to the information about the tour: http://www.bostontours.com/pequots.htm It takes eight people for them to make a stop at the hotel, and they won't take a reservation until the day before. If you're interested in touring Boston (and shopping), let me know and I'll get a list started. The price is reasonable ($42) and you can pay the driver when you get back to the hotel at around 3 PM. They don't take credit cards, though. Let me know.

so you're in charge until Sunday. Make sure you listen to him, lads.

This house

@ September 17, 2002 5:54 PM in An old house revisited - Dan H.

has Stephen Gold's mattress radiators, patented in 1854. The house was built in 1857. It also has a steam radiant-floor-heat system in one of the rooms. It was all working the last time I was there, which was in 1989. The pipe is original; it has seams. I never thought I'd get the chance to go back. Should be a fine day. I'll take some snap-shots.

Yep

@ September 17, 2002 5:52 PM in telephone orders for books?

It's the number at the bottom of every screen on the site: 1-800-853-8882. Thanks for the business. I will use the money to pay college tuition and buy beer.

that tail before. Very easy to spot!

I'll be there

@ September 17, 2002 2:17 PM in An old house revisited - Dan H.

probably by five. You'll find me at the bar in the hotel, on the stool with the seatbelt. C'mon by!

I'll check to the manufacturer, of course,

@ September 17, 2002 1:29 PM in Boiler Primary Pipe Size

particularly with the copper-tube folks, but I can't think of a reason why, if a boiler can take a return temperature of 140 degrees, that a primary/secondary system can't be made better by working with at least a 40-degree temperature drop across the primary. It reduces the size of the pipe and the primary circulator, and this begins to make a real difference when that primary stretches beyond the boiler room.

There's really no reason

@ September 17, 2002 12:28 PM in Boiler Primary Pipe Size

to base primary loop pipe (or pump) size on a 20-degree temperature drop. A 40-degree drop is more like it. Based on the writings of the late, great Gil Carlson, I did my best to make a case for this in "Primary/Secondary Pumping Made Easy!" No sense in leaving money on the job, especially when you don't get any advantage.

If you've read The Lost Art of Steam Heating

@ September 17, 2002 12:24 PM in An old house revisited - Dan H.

you may remember the house that's featured in the first chapter, the house with the 1857 steam system. I got an email a few weeks ago from the guy who bought that house. He wants to know if the steam system can be restored. The house has been unoccupied for 10 years. I'm going to stop by tomorrow on my way to Massachusetts and take a look. This is probably the oldest steam heating system in America and the guy wants to save it. I never thought I'd ever have the opportunity to go back. Pretty cool, eh?
