Sorry, Homey, I thought you were the original poster.
Viessmann is an excellent company which suffers from its products having limited availability in our part of the world. Service and repair parts are scarce and support contact can be difficult though the company is more than willing to help when a problem arises.
That aside, they make outstanding high-efficiency boilers that are hyper-engineered to withstand the low flu temperatures at which they are designed to run.
That’s actually more difficult than dealing with higher temperatures. Low temp is where their highest efficiency is realized.
(It’s a long story)
You’d be right to at least consider using one of their products. Also check out Buderus and Triangle Tube.
To my knowledge, Viessman doesn’t make a steam boiler.
Cmu, all boilers become less efficient with age. Scale and sediment collect on the sides and floor of the heat exchanger and insulate the water from the flame and flu gases.
Regular maintenance helps delay the inevitable.
mp: Can you elaborate of why steam boilers “lose points” from the day they’re installed? Have not heard that before. Is this different than for hot water “boilers?”
Thanks
Master Plumber,
What do you think of Viessman? It was recommended to me over Peerless, but I would love you opinion.
If you’ve got a steam heating system, the options are very limited. All steam boilers top out at about 82% efficiency.
Even if you spend more on a hyper-engineered boiler like Burnham’s unique Mega-Steam (for oil):
http://www.burnham.com/mega.htm , and pick up about 4 percentage points, you’ve still got a low-efficiency system (still much better than hot air) for the boiler to work with.
The bottom line is the most efficient steam boiler is any new or well-maintained unit as they start to lose points from the day they’re installed.
There is very little difference from one brand or model to another where efficiency is concerned.
Construction quality and customer service are the bigger issues when comparing manufacturers. I like Burnham, Peerless and Weil-McLain in that order.
Has anyone ever seen this knife before and can it really be used on a bayonet? It is said that it can fit together with a AK47 rifle. Maybe it is a copy of some old military knife that was used back in one of the wars? The website that it is on is http://www.lducompany.com I am wondering if it can fit on any other types of guns or rifles. Does it look like something that would be used by Chinese, Koreans, or Russians. Here is a link to the knives page http://www.liangdianup.com/knives_1.htm and it is the knife with the number 406023 right at the top of the page.
Any help would be appreciated before I order it all the way from China 🙂
