Building where carbon monoxide leak injured 5 lacked required detectors

@ September 22, 2010 2:11 PM in Building where carbon monoxide leak injured 5 lacked required detectors


@ August 9, 2010 6:40 PM in Can I convert a Taco 007 to a Taco 007-IFC?

It will probably be a long time before you need to think about replacing your Taco circulator.  But if you do, you can use the guts from the old one by removing the 4 screws that hold the can to the volute and just popping it out and changing it. 



visual and audible

@ July 16, 2010 12:16 PM in Man dies in manhole incident

Dave, you are correct.  Both types of alerts are required although the standard does not directly say so.  In the appendix that offers explanations for how to comply with the standard, it says you need both.

Even though the news article only said "lights flashing", that does not mean that they got it all right.  It is troubling that emergency personnel can lose sight of their primary responsibility which is to take care of their own safety first.  If they go down, they can't save anyone, can they? 


but consider this

@ June 24, 2010 10:04 PM in UK Giannoni Heat Exchanger Review

The Triangle Tube appears to have a very good design with consideration to the typical maintenance habits of most consumers.

My Knight 80 is so far so good.  And I hope it continues that way.

The downside to the TT is the lower input capabilities.  The  heatloss on my 3000 sq. ft. house with 3 zones of fin tube base board is only less than 60K btu's.  My hot water needs are met just fine with this  unit.  So, the point is if a smaller TT were out there, that would be very attractive.

What I like about the Knight probably most of all is the ease of programing.  I've cleaned it a few times so far and as far as I can tell, so far so good. 

The UK article is very enlightening.


We recently replaced

@ May 15, 2010 8:39 PM in Personal CO detectors/monitors/alarms

all of our personal CO monitors with the Rattler - same one that you have Mark.  Previously had the AIM 450 monitor which I liked a lot, but after 7 years, it was time to retire them.  Our industrial hygienists use something different that has data logging capability. 

Things I like about the Rattler include having 2 alarm points that are user adjustable and the relative ease of calibrating.  The main drawback for me is that the display is in front instead of on top like the AIM unit has.  It seems that all or most monitors are built this way now.  I like to be able to look down at my vest where it is clipped and see the readout.  Oh well.   The battery life is good and double A's are easy to find.

The weekly email from Dan got me there.  You should already be getting the Thursday email.


Thanks again Dan

Just got done viewing the interviews with Mel Dubin.  What great stuff!  It's so wonderful to listen to stories of how people got their start and where it all went.  Mel's recounting of how a twist of fate made his future and that of some others made me laugh.  Usually going to synagogue is supposed to be a good thing, but I suppose that's open to debate, all things considered!  Herb Wasserman might have an opinion on that.

Looks like you had a great time listening too.  I'll look forward to the next installment.

Thanks for sharing.


Well, there's this:

@ March 4, 2010 9:27 PM in Happy Birthday Dave Yates!

Happy Birthday Dave. 

It's great that you get to spend your time doing so much fun stuff, helping others (and still making a living).  

What do they say?  Make hay while the sun shines.  Looks like you are living that idea.

Best wishes for this B-Day and many, many more.


Thanks Mark!

@ January 21, 2010 8:39 PM in Don't mess with grandpa...

I really liked that.  I immediately thought about my 80 year old father inlaw.

Can't beat the Wall!!!


many are the same inside

@ January 5, 2010 11:11 AM in kitchen appliance brand suggestions? (OT)

I inspected an Electrolux freezer plant a year or so ago and saw that the main difference between many brands is the label on the front.  Electrolux, Whirlpool, Kenmore, Maytag, Amana, GE, and others that I can't think of now are all made at the same plant, on the same lines, with the same parts, by the same people.  Compressors come from either China or Brazil. 

The corporate safety guy walking with me was from a dishwasher plant in North Carolina where they make all those brands.  It's really amazing that they can pump out so many machines a day.  Overall quality, I think is decent, and reliability should be about the same for any of those brands.

If you buy an American brand, I would suggest that you buy on price and features.  And no, they don't last as long as they used to.  I had lots of fun with our old Maytag dishwasher a few years ago and the new one works and is quiet but I don't think it performs as well.  Probably due to smaller motor and pump to get the energy efficiency ratings.

Good luck


wet windows

@ January 2, 2010 9:59 PM in condensation on windows

You are doing the right thing to keep the heat in a little better by closing the shades, but with that you are very likely to get condensation because the cooler air next to the windows can't hold as much moisture as the warmer air on the other side of the shades. 

It's really a catch 22 situation where you want to add humidity in the winter, but to keep the windows free of condensation, you need less humidity. 

Google window condensation and you will find the recommended level of moisture in the air based on outside temp.  It's a lot less than you would think. 

I just put in new Pella windows this fall and deal with the same issues.  Air movement across the windows and opening the shades during the day helps a lot.


Good for you

@ January 2, 2010 2:49 PM in A new beginning

And good for Lochinvar too.  Good companies attract good people and I'm glad for you.  I hear that they have good Bar-B-Que in Nashville.  We'll be looking for recommendations on the best place to eat ribs after you get settled! 


Big Smiles all around!

@ December 13, 2009 11:10 PM in I'm a Grandpa!

That's really great news Dan.  All the best to you and the whole family.


Ya know Ron,

@ July 31, 2009 9:20 PM in Stayed with oil heat ( Ron Jr. )

you could post those pics as "Anonymous" and it's still easy to tell it's your work. I'm always blown away by your installs. Thanks for sharing. But, it's gotta feel weird to be able to work standing up, not bump into each other and actually have some space between you and the walls. Larry

My condolences

@ July 19, 2009 11:42 PM in Mothers (Dan H.)

Dan, My condolences to you and your family on the loss of your Mom. I know you will carry her with you in your memories forever and those thoughts will always make you smile. She raised a good son. Take care, Larry

good for you ray

@ July 18, 2009 12:09 PM in 20 years for me

it's been a bit more than that for me, but what i want to know is why do almost all welders smoke? it's not like they don't get enough smoke from the job........ Larry


@ July 3, 2009 11:24 PM in Shlomo Dahan

Bob, Thanks for your private reply. I'm sure there are no shortage of unanswered questions surrounding this sad event. Licensed or not, it's a lousy way to go. Larry


@ July 3, 2009 10:41 PM in Shlomo Dahan

just curious about the unlicensed aspect. I did not see anything in the articles that mention that these folks were unlicensed. Do you have additional information about that? I don't dispute you that there are plenty of unlicensed operators out there that don't work safely. I see plenty of them in lots of trades. I also see licensed union guys doing things that would make you cringe. Thanks for any clarification you can offer. Larry

thinking green

@ July 2, 2009 12:57 PM in low power zone valves

The White Rodgers 3 wire valve does what you want and so does the Taco EBV. I'm not sure but the Taco might be the Low Power Leader! Good luck. Larry

very sad

@ July 2, 2009 9:27 AM in Shlomo Dahan

It's a terrible tragedy and completely preventable. My heart goes out to the families of these 3 men. Its sad that this scenario of multiple deaths in confined spaces is seen over and over again. Larry

arcs and sparks

@ June 18, 2009 10:12 AM in a new profession?

Will, As I understand it, the spinning rotors on the helicoptor generate static electricity and lots of it. Static charges can be created when two dissimilar materials are moved across each other such as the rotors through the air. This can be particularly dangerous when pouring flammable liquids as just the act of pouring can generate enough static to create a spark and if conditions are just right, it will go BOOM. I also don't plan on inspecting that guy's worksite! Larry
