Tom always helped everyone.

@ February 19, 2014 4:47 PM in Tom Schwarz has passed away

He was a good man and a superb contractor. I will miss him. 

My thoughts, too.

@ February 19, 2014 7:51 AM in How serious an issue is water quality?

I've moved this thread to the Main Wall so more people can give opinions. I saw this product at AHR and was impressed. I wonder if there is a market for it in the U.S. Thoughts appreciated.

That sums it up beautifully.

@ February 18, 2014 10:03 PM in how prevalent is this?

We've been discussing, and witnessing, the dangers of these open radiant systems since this site began 17 years ago. The attraction of that low price is still compelling, though.

All we can do is continue to tell what we've learned. Not everyone will listen but we do know that we tried.

Adults make decisions and deal with the consequences.

Radiators in your bedroom

Are they cast iron?

Post title is just that. What you type into that box appears at the top of your post. I'm glad you're here. 


@ February 18, 2014 11:58 AM in Steam boiler replacement quote

We have 33-year-old twins. They have two sisters - 34 years old and 36 years old.  All females. Imagine what THAT was like back in the day. I now have five wives - the big one and the four little ones, and they all have strong opinions about all that I do.

Heaven help the contractor who ignores the women in the house.

The wife.

Anyone who comes to my house and doesn't talk to The Lovely Marianne will not be in my house for long. She's brutal. 


@ February 18, 2014 11:28 AM in Steam boiler replacement quote

Educate yourself and then decide whether it's something you and your uncle can handle. It's all about the details. If you guys are going to be the installers, ask yourself the same question I suggested you ask the contractor: Will the system heat my house comfortably and without noise when I'm done? Can I guarantee that? 

No problem, KC.

@ February 18, 2014 11:09 AM in Steam boiler replacement quote

Thanks. We don't discuss pricing because it's tough to tell what conditions are on the job from a remote location. Also, pricing varies by location and it's not fair to anyone if we start comparing. It's really a matter between the contractor and the customer. If the price isn't right, you don't hire the contractor.

As for the rest, some contractors don't go into great detail on a quote because they're concerned the potential customer will just shop their quote, looking for a lower price on the same stuff.

I would buy results. Will the system heat my home comfortably and without noise when the contractor is done? Will the contractor guarantee that?


@ February 18, 2014 10:48 AM in Steam boiler replacement quote

is something we don't discuss here. I realize you didn't ask about his pricing but I don't want this thread to go in that direction. Thanks.

Is the sound constant?

@ February 18, 2014 7:52 AM in Bell and Gossett 100 mystery sounds

Or intermittent?


@ February 17, 2014 3:01 PM in Bell and Gossett 100 mystery sounds

Are you using 20-weight, non-detergent oil? Did you check the wicking to see if it's burnt? Did you press the wicking onto the bearing with the back end of a pencil?


@ February 15, 2014 7:52 AM in Back in the States

We're still in Florida, but starting a long, slow drive back today, with visits along the way. It's nice to be warm.

Thanks, Terry.

You're seeing what I'm seeing. A few days ago, Tom Friedman in the NY Times wrote a column about this book:

So I read it, which is what I do because I have time on my hands and am forever looking to learn. The book is an eye-opener, especially in the way it explains the problem with measuring a country's progress by looking at GNP and not the effects of the Second Machine Age, which often involves taking old ideas and combining them with new ones. And that's what Marshall Cox is doing with this product.

I'm sitting up straighter and paying serious attention here, and for all the reasons you stated. And more. Thanks.

I'm with you on that last thought.

@ February 10, 2014 4:39 PM in Meet The Cozy

I don't see TRVs as the competition to this. I think this is totally unique at this point.

I did see something a few weeks ago that really got my attention. I was visiting the Arsenal in NYC's Central Park. This is a landmark building and was the original Museum of Natural History. It's in the zoo, across from the seal tank. I was there with some friends from the Parks Department. Someone had installed Danfoss TRVs years ago but never bought the operators so the valves were nothing more than wide open valve bodies. The valves all had the original caps to protect the stems. I removed some of the caps and the stems were completely corroded. Some were leaking steam into the caps. These valves had never moved in all those years, which may be part of the problem, but they got me thinking, and what Marshall wrote has me thinking even more. 


@ February 10, 2014 12:17 PM in Meet The Cozy

Love them and have been working with them since my old boss took on Danfoss in 1972. The challenge, though, is many landlords don't want to install TRVs because of the piping involved and the possibility of breaking pipes. I've head that soooo many times. And we've all seen TRVs installed improperly, with sensors sitting on hot pipes, or heads getting broken off the valves. What I like about the Cozy is the ease of it. I thihk that's what's going to make this thing big.

Patrick, I felt the same.

@ February 10, 2014 12:11 PM in Meet The Cozy

When he first got in touch I told him he was nuts, but then he asked me how he could get to be not nuts, so we had a couple of days of talks and I told him a lot of stories about the real world and still wasn't convinced. The turning point for me was the Columbia Lab. Seeing what he has already done that goes WAY beyond the Cozy, his willingness to listen, his ability to take advice and learn quickly, his ideas for where the product will go, and his level of enthusiasm (this guy is ridiculously positive) made me see the Cozy in a new way.

I'm enjoying listening to all the comments, especially the skeptical ones, because they remind me of where I came in on this. Keep 'em coming!

Joe, you're making me smile.

@ February 10, 2014 6:47 AM in Meet The Cozy

I went at Marshall the same way you just did. My first thought was that he was reinventing the wheel because we have TRVs that will do the same job. He listened to everything I had to say and he never argued with me. Then he asked if I ould come into the city and visit with him. That's when things started to change. You have to meet the man to understand. He doesn't argue. He shows all sorts of respect. He listens like mad and he thinks like a scientist. If someone tells him he's wrong he considers that he might be and then sets out to find out if he is indeed wrong. I don't meet too many people like that.

So here's what happens next: You visit and he shows you what they're doing and all the science behind it. You make a suggestion and he comes back to you a couple of days later with that suggestion implemented, only with a few other things you hadn't considered. He then asks if that's okay?

Marshall is talking about future features for the Cozy that make my jaw drop. I'll let him tell about all of that when he's ready, but please believe him when he says the stuff he's saying below.

Thanks for engaging him. The more you do that, the better Marshall gets.

It's not a hermetic seal around the radiator

@ February 9, 2014 7:17 PM in Meet The Cozy

It's reflective on the inside and it's killing the convection until it's needed. I wish you could all see this in real life. I'm not easily convinced, and I blew this off when I first heard about it, but then I went to see it and I shut up for a while and let them talk. These guys are very, very smart. 

Not a problem,

@ February 9, 2014 7:14 PM in Meet The Cozy

They thought that out.


@ February 9, 2014 5:25 PM in Meet The Cozy

No matter how much we do, people will each perceive comfort as something unique to themselves. This offers a targeted solution to that. It's simple, yet so tuned into what people are interested in right now. I mean who else offers an app that can control a steam radiator?

These guys don't know what can't be done, so they just go ahead and do it.

If everything is working that well

@ February 9, 2014 5:16 PM in Meet The Cozy

then you have achieved success! Well done. The Cozy is for tenants that want comfort in apartments where management won't do the extensive work that you've done for the whole building. What I like about the product is that it gives individual tenants power in those situations. It also saves fuel and for the reasons Marshall listed below so everyone wins.
