@ January 6, 2014 10:38 AM in Did someone say Design Day?Ok, so I'm all for testing the limits of the system and all that, but this is really cold. Its warmed up to -20 and should stay about there all day. Design day here in Minneapolis is -16 and the little Knight is just humming away. Wind chill in the -50 range just adds to the whole experience. Looking forward to the end of the week when it is supposed to get to 30.
What's it like where you are?
@ December 23, 2013 1:30 PM in Toronto calamityMy experience has been that my Lochinvar Knight runs fine with power from our GE generator which is, I think a rebadged Briggs unit. The Grundfos Alpha system pump also runs fine.
@ October 10, 2013 2:56 PM in This is interestingI suppose we shouldin't be surprised that this was coming. The smart home is getting smarter. Not for everyone, but it gets good style points.
@ September 4, 2013 12:29 AM in You can't even go fishingWell this sucks about as much as possible.
This answers a question or two:
I'm surprised duct tape wann't mentioned here.
@ August 22, 2013 10:38 AM in Boiler at Minnesota daycare explodesThere are a few comments that I could make, but I'll let all of you do that. The pictures are pretty impressive.
@ June 4, 2013 9:58 AM in Buy AmericanI believe the Walmartization of America has been coming for some time. It seems to be our natural tendency to want what ever it is at the lowest, cheapest cost. I found an old (very old) pair of jeans that had a made in USA Union label. You just won't find that any more.
@ June 1, 2013 4:03 PM in Thank you Alex MarxAnd thank you Dan for Thursdays email blast. And, since you asked…
Personally, I think the skill, determination and resources available back in1935 are pretty amazing. As far as the safety and health end of things, obviously I’m glad we have progressed to doing things a bit differently. Eye protection, clothing to avoid burns from molten metal are a few areas that have improved since then. I have to wonder how many of these fine gentlemen were able to enjoy retirement. The dust from sand casting has caused many a foundry worker to die early from silicosis.
Sure, a person could make a fairly sizable list of things that could have been made safer, but that’s how they did it back then. We learn as we go.
I do lament the loss of big manufacturing in this country. That of course is a different
@ May 12, 2013 4:03 PM in Steam at WorkGreat video and nice to see such an operation going. What can you say? A step back in in time for sure and I suppose some OSHA inspector might have some concerns with all the whirly spinny things going and everything else. But I think it's really cool and looks like maybe all family run. I'd have a pretty tough time shaking a stick at those folks. And, i'm pretty sure that the dog doesn't work there, so it's not an OSHA concern :)
@ March 25, 2013 2:11 PM in A good storyTim, I agree that the technician’s judgment may have been questionable, but the concept of Good Samaritan is what most likely kicked in and maybe the few extra minutes of fresh air that the guy in the basement got because of that saved his life. As far as what various exposure levels mean, here are a few numbers.
IDLH: 1,200 ppm
Existing short-term exposure guidelines: National Research Council [NRC 1987] Emergency Exposure Guidance Levels (EEGLs):
10-minute EEGL: 1,500 ppm
30-minute EEGL: 800 ppm
60-minute EEGL: 400 ppm
24-hour EEGL: 50 ppm
Lethal concentration: Human = 5,000 = 5 min
OSHA 8 hour exposure limit: Minnesota = 35 ppm, federal = 50 ppm.
So even exposure to the IDLH does not mean that a person will tip over and die. It depends on the amount of carboxyhemoglobin (COHb) in the blood which is dependant on the level of CO exposure verses time of exposure.
And I still say it's a good idea to have a personal CO monitor because if you don't test, you don't know.
@ March 14, 2013 3:24 PM in A good storytechnician saved a man from his home, which was flooding with carbon monoxide.
Do you have a personal CO monitor?
@ January 26, 2013 1:38 AM in some of the dead men showing offOur commisioner thought it would be a good idea to show some historical images of various workers and we now have a great display on the walls of the lobby of our building.
@ December 30, 2012 3:08 PM in Hot spot at top of indirect hot water heaterthat the insulation under the handhole inspection cover is not as effective as the rest of the tank insulation. Or there might not be any there at all. Check your documentation.
Hope you are enjoying your new condensing boiler too.
@ December 23, 2012 1:44 AM in At what point ,The OSHA permissible exposure for an 8 hour period is 5000 parts per million. That's 1/2%. The short term exposure limit is 30,000 parts per million (3%).
Hope that helps.
@ December 7, 2012 4:43 PM in where to put electric mat radiant heat in kitchenI would suggest that you do it right the first time since you won't do it a second time and won't be happy if your feet are not where the warmth is. You should consider covering as much floor area as possible because where ever the heat wires are not - you won't have warm floor. The heat does NOT spread past the area of the wires. At best an inch or two but that's it. We have electric radiant in both bathrooms and it is very apparent where it starts and stops. As far as having two thermostats, I would only do one. Since you are already thinking about where it would be nice to have warm floors, like the back door area, etc. my suggestion is to go with the most coverage and you will not be sorry.
Good luck and enjoy you remodeled spaces.
@ November 12, 2012 7:38 PM in Laing Thermotech re - circ pumpI have had mine for a number of years and have a mixing valve at the hot water tank and all is well. At the faucet where the recirc is, warm water is right there. At the other faucets near by, warm water is there within 6 seconds. I am very pleased with the whole thing.
@ November 9, 2012 9:57 AM in Boiler stand for TT boilerhttp://www.8020.net/
give them a design and they will build it or buy material and you do it. really works well.
@ November 8, 2012 7:56 PM in Step Up To The Plate Manufacturers!I have a Knight that is about 5 years old. Our generator, a GE which is actually a Briggs & Stratton seems to work just fine. I think that there are many different situations where a system will or won't work with axillary power.
Let's hope everyone affected by the storms come out ok really really soon.

The effects are catastrophic and deadly.
@ October 8, 2012 1:39 PM in CO death at appartment in Coloradohttp://www.gazette.com/articles/monoxide-145635-one-critical.html
very unfortunate situation.
@ September 18, 2012 10:05 PM in Leaking HX on Vitodens 200Too bad about the V. I'm actually surprised that there was no inlet-outlet differential limit fault like on the Knight boilers. Or, for that matter, a low flow fault. I suppose there needs to be a flow switch for that one. I don't recall anyone posting any pics of any Vitodens that look that ugly. Maybe most V owners have periodic service. But that does prompt me to do my annual service on my Knight.
