9/11 memory

@ September 8, 2008 10:02 PM in Recalling 9/11

I had just dropped off my kids at school and heard on the radio about a plane hitting the building. Like others I thought a private plane had done something stupid. By the time I got to the office the facts were clearer. When I saw the second tower fall and everything that followed, my overwhelming thought was that Everything had changed. I thought about what my kids' lives were going to be like, and then was consumed with wondering if my children that I had just left at school were safe. So much can go through your head in a flash. I now wonder what my dad thought when Pearl Harbor was attacked and if his thoughts were in the least bit similar. The days following were so very wierd with NO planes in the sky. It was so quiet. Several from my group and other OSHA folks from across the country went to NYC and helped out at the site to try to keep those dealing with the aftermath safe. I think the effort was good, but the results were mixed. There are apparently many who suffer the effects of what they breathed in. Thanks John for starting this. Larry


@ September 5, 2008 10:47 PM in condensing boilers for high-temp application

I know what you are talking about. And while there will always most likely be applications for cast iron boilers, the trend in natural gas prices will hopefully make it a little easier to promote the most efficient products out there. Remember, people poo-pood fuel injection in cars too as too complicated and prone to failure. Tell me where you can get a car with a carburetor now! Larry

Thanks Jim

@ September 5, 2008 10:26 PM in From our guies , who protect us

Many of us know someone who is serving over there now. My co-worker, Jim Schultz and his daughter are with the National Guard and are serving there right now. Please keep a good thought for them. Thanks, Larry

Here's my deal...

@ September 5, 2008 10:13 PM in condensing boilers for high-temp application

I've got a Knight 80 feeding 3 zones of baseboard designed for 180 at -20. We've added some insulation years ago and are at about an R44 or so. Previously the insulation was about 6 inches deep. So the baseboards are a little over sized for our current situation. For most of the season, there was plenty of condensing and the boiler was running at less than 50% output. I think that condensing is great, but it is talked about a lot more than modulating. The modulating is where I believe the most savings are. But, the difference in price for a boiler that only modulates verses one that both condenses and modulates is, as far as I know, not that great. For anyone looking at replacing a boiler these days, why even propose anything less than the most efficient system out there. The price difference is too low to sweat about. The payback is reasonable and my savings in the first season were about 30% compared to a cast iron slightly oversized boiler that I had added reset to some five or six years ago. Just my two cents worth. Larry

I am very sorry to hear of the passing of your mother. Please know that my thoughts are with you and your family, as are all the heartfelt thoughts of everyone in this community. The pictures that you shared are great and speak volumes. Larry

My deepest sympathy

Dave, I'm so sorry to hear of your Dad's passing. My thoughts are with you and your family. Larry

Hard to remember

@ August 20, 2008 10:32 PM in What was your first concert?

Some memories are a bit foggy from back then, but I think it was Johnny Winter with his brother Edgar at the Labor Temple in Minneapolis somewhere around 1968. Larry

This was the new Minnesota plumbing code. There have been a few additions over the years. Perhaps this will find its way to the library. Larry

water gas revisited

@ July 23, 2008 8:55 PM in A use for carbon monoxide

I saw this today about making ethanol from trash. Burning trash with incomplete combustion to make CO as part of the ethanol production process. Interesting idea and the numbers being tossed about are impressive. It's interesting to see what American ingenuity can come up with when the price of fuel gets to what it is now. I hope these folks are successful. My price per therm has jumped from under a dollar to over $1.50 per therm and rising. The demand for natural gas is going to continue to rise at a fast pace. Larry

some other fun stuff

you don't usually see this in boiler rooms. that's what you call good timing. Larry

Very sad

My deepest sympathy for your loss. You and your family are in our thoughts and prayers. Larry

common sense

@ June 6, 2008 9:27 PM in CO kills sisters

I've tried to stay out of this one for a variety of my own reasons, but since the concept of "common sense" has been tossed in a number of times, my two cents worth follows. Common sense. What is it? How do you define it? Do we all have it? Is yours the same as mine? Or the same as the person who does something that defies your logic or my logic? I actually gave up on common sense several years ago. I have seen so many different ways for seemingly normal people to maim or kill themselves, I have come to the conclusion that common sense isn't so common. Why would someone dig a hole in the ground the same dimensions as a grave and then just get in? The answers range from: That's where the pipes are, and We've always done it this way for 20 years and nothings happened yet, to Yeah, I knew it wasn't right, but we didn't have a trench box. Every year in Minnesota at least one person dies in a trench. The numbers are similar across the country. How about working 30 feet above the ground without any type of fall protection? Or sticking your arm up to your elbow into a punch press while it's running? And then losing it. Or run a propane heater in a building being framed and nicely poly wrapped without a C.O. monitor. That happens a lot. Sometimes a whole bunch of guys end up in the hospital. The list continues to grow. And I stopped being surprised by much of anything. From my perspective, common sense does not exist. Larry

nothing like being protected

@ May 17, 2008 12:34 PM in cleaning stainless...

Maybe Perry can get you some nuke waste and I'm sure you can find some asbestos lying around easily enough. I know you like to give me grief about all the safety stuff, but I've seen what "bad nasty stuff" (technical term) like hydrofluoric acid can do and it's not pretty. Good luck with the move whenever that happens. Larry


@ May 17, 2008 12:06 AM in cleaning stainless...

I don't think you want to start dousing your grill with hydrofluoric acid. This is used to etch glass and is really nasty stuff even in low concentrations. And what's wrong with a nice copper color? Larry

Nikola Tesla

@ May 12, 2008 9:27 PM in Where do we go from here?

I eagerly await a modern day Tesla to unleash the limitless energy that was theorized so many years ago. Since I'm not holding my breath, I have replaced my boiler and improved that part of our carbon footprint, and I'm thinking about uncovering the old bike which gets better mileage than the car. As far as biomass goes, let me know when you've got a lot of switch grass and we'll start fermenting. We've got a bunch of ethanol plants here sucking up the corn that could go for food. I think the reality is that until Exxon and the like can find a way to charge for Tesla type energy, we are stuck with what we've got. Larry

best to buy them new

@ May 2, 2008 1:54 PM in anyone have any dan holohan books they want to get rid of

it has been my experience that these books only go up in value after they become used! Larry

more real world data

@ May 1, 2008 10:06 PM in your thoughts part 2

I've just been through my first season with a mod-con. The savings are better than 30% over a somewhat oversized cast iron boiler with ODR. The amount of time spent firing under 50% rate verses over 50% is in my opinion significant. 2073 hours under vs. 840 over. Sometime this summer I'll open it up and clean it out and I suspect that there won't be much to deal with. We'll see and I'll have pictures then. This system is 3 zones of fin baseboard that has provided 70 degree comfort with water temps well under 160. Design temp 180 at -22. Larry

It has been quite a while hasn't it?


@ April 20, 2008 12:26 AM in Viessman or Knight/Lochnivar Condensing Boiler?

I can really only comment on the Knight from my own experience. I have an 80M in my house since last fall and I've been extremely pleased with the performance. The construction of the unit is top notch and the programmability is very flexible and easy to use. It's important to be comfortable with your contractor and that they have experience with which ever boiler you end up going with. The Viessman is supposed to be in a class by itself and it most likely is. Many people here speak very highly of the Vitodens. One thing you haven't mentioned is if a proper heat loss calculation has been done. Even with a modulating boiler, you don't want to oversize it. My energy savings with the Knight have been substantial, to say the least. Good luck with whatever you end up going with. Larry

Bovide, Thanks for thinking about how to do the job safely. Larry

need more info

@ April 10, 2008 7:54 PM in shoring

bovide, You need to know the OSHA standard for excavation (or someone does) to be a competent person. You can use a trench box or angle the sides back depending on what type of soil you have. Let's talk more about this. Bad trenches kill plumbers every year. Larry
