Vitodens tech lit and pricing

@ July 30, 2009 9:48 AM in Viessmann Vitodens Boilers

I for one would love to have tech literature on the new Vito 100 and 200. Thank you for the offer. Does anyone have the latest MSRP price list. I have a July 09 version and it does not have the new boiler pricing included. To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

Other Opinion

@ June 21, 2009 10:08 AM in Expert Witnesses

By the way, I do indeed have the mfgr rep's opinion. It so happens that I have attended 3 trainings with this company. They were very happy to provide me with an honest and favorable opinion of my design. To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

Court

@ June 21, 2009 10:05 AM in Expert Witnesses

In court only the lawyers make money, its no win at this point all you can do is cut losses. How true this is! I will go to great lengths to resolve disputes out of court from here on in. As far as the "expert" goes, we were only 25% through the job when the progress payment failed to come through. There was no performance to evaluate, only a design.

Expert Witnesses

@ June 21, 2009 1:28 AM in Expert Witnesses

Interested to hear some opinions on this one. To make a long story short... Filed suit against a GC who would not pay his bills. Instead of working things out with us, he decided it was best to spend twice as much on lawyers than he owed us. Naturally, once the case got under way, all the work we did turned out to "negligent" and our design "faulty". While this particular GC might be a certifiable bad guy, what rankles me more is that a prominent member of the RPA, someone who has recently bid against us on jobs in fact, has appeared on their witness list to testify against us, presumably to trash our design and installation (which I can assure you is perfectly sound). Now I have seen my share of Hall of Shame installs by other contractors, but that does not mean I would be willing to testify aginst them in a court proceeding. Why? To me, this is just simply a no go. Would you take time out from your work to take the stand against a fellow tradesman? I'm curious. Am I naive? Misplaced sense of honor? Could he really want business from this guy THAT bad? To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

How many Btu's can the concrete accept?

@ June 6, 2009 1:18 PM in Radiant Heat in Exterior Spaces

One more time we have been asked to heat a semi-enclosed patio. I have not had great success with this in the past and thought I might try again. My question is this. How much heat can I actually put in the slab? The design would be for a 1600 sq ft insulated slab. 8 400'loops at 6" on center, 7" at the turns. Design flow rate about 1 gl/loop for 8gpm total. At a 20 Delta T this would give me 80,000 mbh or 50 btu/sq/ft. Air temp on the patio would be a minimum of 50. My question is, can concrete accept more btu's than that if it is not so cold outside. I want a slab surface tmp around 105. Would using a larger boiler gain me anything under these circumstances? What if I double the flow rate? I have designed Snow Melt systems with well over 100btu/sq/ft, but they have ICE sitting on th surface. This is a dining area of a restaurant. Again, will a bigger boiler with more BTUs available gain me anything? To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

ESP Hi-V air handlers

@ March 1, 2009 12:15 AM in Hi-V Air Handlers

I am surprised to hear anything negative about the ESP product. They are terrific. ECM motors. Smart Circuit board with on board pump relays. Dip switch controllable air flow. I love their gear. I use their conventional static pressure fancoils as well. In all fairness, what are the problems you have heard?

Vito 100 Fault

@ February 22, 2009 12:37 AM in veissmann vitodens fault codes

I do have a Vito 100 that keeps faulting to F4. I'm going out to look at it next week. Is this the fault code you are getting? To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

Vitocell Recovery

@ February 17, 2009 9:14 PM in Vitocell Tanks

Paul, I also like triangle tanks because of the low pressure drop. Have you found you can use a Vitocell v-300 53gl with a 6-24 where you would otherwise use a triangle smart 80? To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

Vitocell Tanks

@ February 17, 2009 10:21 AM in Vitocell Tanks

I need to hear from from the Viessmann devotees out there, and everyone else as well, on why Vitocell Stainless tanks are worth twice as much as a Superstor or any other choice. We install Vitodens boilers exclusively. I have always been able able to justify the expense by their exemplary build quality and reliability, the fact that the primary pump is on-board etc. But Viessmann tanks? There are no moving parts in a tank. I believe Viessmann tanks are built better than anything else out there. I know they they have an inspection panel and a lifetime warranty. Will they actually make more hot water faster with, say, a Vitodens 6-24 80mbh boiler? I have looked over the performance data. It is confusing as each mfgr publishes different criteria. Help me try to justify a $2,200 difference between a Viessmann tank and an HTP tank. If, for example, someone has found that I can get the same recovery from a Vitocell 53gl tank as an HTP 80gl tank, then I would see it. We often install SuperStors and Smart Tanks. Obviously I would like to sell all Viessmann all the time if possible, but especially in this economy I need some back-up. What's the word?

How Much?

@ January 29, 2009 9:01 PM in Combustion Analyzers

I guess the question also is: How much do I need to spend to get a tool I can trust and will be proud to own? That being said, just because I sell Viessmann boilers doesn't mean I want to spend $5k on an analyzer if I don't have to.

What tool are the Serious Pros packing? We will be using it for LP and Natural Gas. Mod Con boilers. Trying to balance price and function. Thanks in advance. To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

Well then

@ January 25, 2009 9:50 PM in Vitodens - External Call for Heat

Thanks Paul, So an external call does indeed put the Vitodens to hi-fire. In that case: If I retain the code for DHW priority, I get DHW priority. I should only need the external call for a short period of time. How about turning off the Radiant secondary circulator via a NC relay during a high fire external call? Then I get DHW, then Spa, then Radiant priority without the whole mixing valve. To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

EBV Valves

@ January 25, 2009 7:07 PM in Problems with Taco zone valves

I'm very pleased to see this post. I also very much like the design of the EBV. The indicator light, the plug in connections, etc. Unfortunately,we have also had to replace a number of the actuators in the first two years and I am on the verge of going to another product that will not provoke so many call backs. If I am confident that this will not be a common problem indefinitely and that I can get a quick warranty replacement, I would rather keep using them. I'll ask the office how easy it has been to get warranty replacemnents. To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"

Vitodens External Call

@ January 25, 2009 6:48 PM in Vitodens - External Call for Heat

Who has used the Vitodens "external call for heat" function? I know this call connects on the 4.1 terminal in the comfortrol. My question is: 1) What temp water does the boiler output on an external call for heat? Does it go automatically to high fire? Does one program in the temp in the Heating Circuit B function? 2) Does an external call have priority over a DHW call? My scenario is a Vitodens 15-60 with a low temp radiant circuit, a DHW tank, and a tube and shell HX for Spa Hot Water Production. I'd like to do this without the Viessmann Mix Valve set up if possible. I'd like the priorities to be DHW, then SPA heating (It should only take the boiler about 10 minutes to heat the solar pre-heated spa), then Radiant. What say ye?

Question

@ January 13, 2009 9:06 PM in Anyone read Hebrew?

I'm amazed again at the breadth of knowledge here. G-d bless the America AND the wall. Just curious. How does Aleph/Mem/TAf come to mean office? I figured it would be something like the Hebrew "Misrad" or German "Buro". Alas, the last of the Yiddish speakers in my family are no longer with us, but hey, they outlasted the Nazis by a number of decades!

Your 1st idea

@ January 13, 2009 11:17 AM in Vitodens - No DHW Priority

In the Vitodens there is solenoid which directs water either to DHW tank or the heating circuit. There are 2 small wires with small spade connectors that connect to this solenoid. One of the connectors has "30" marked on it. This solenoid is activated (or de-activated...don't remember which one) via a 24V signal. A 24v coil relay connected here will cut out the white wire to the ahus By the way, this is true ONLY in the 6-24 or 8-32 model. The 11-44 or 15-60 does not have this set up. This is how you could "fake out the AHU's to think that the call for heat has been satisfied. Working with the sophisticated electronics I'll have to think on a little bit. Whose fancoils are these? I am most familiar with ESP out of Edmonton, Alberta.

Good one

@ January 13, 2009 7:15 AM in Vitodens - No DHW Priority

Simple, smart, effective. Good plan. Love that

Can't do both at the same time

@ January 12, 2009 3:30 PM in Vitodens - No DHW Priority

The Vitodens will have one temp DHW production (either high fire or 20 higher than tank temp depending on coding). Most hydronic AHU's are rated for potable water. One solution is to run the AHU's out of the Vitocell and use a mixing valve for House Hot. Alternatively, you can cut in a NC relay to the 24V solenoid inside the Vitodens to kill the fans when DHW is called. We have done both.

Astounding

@ January 1, 2009 8:30 PM in Anyone read Hebrew?

The body of knowledge available on The Wall is truly astounding!

Armband

@ January 1, 2009 3:04 PM in Anyone read Hebrew?

I actually read and speak Hebrew well enough, but that is not going to help us because the writing appears to be in...Yiddish! What it says is: "Satzeler Emet" Not sure what this means. But this should put you on the right track.

Chanukah

@ December 21, 2008 8:24 PM in Almost Sundown Hanukkah 2008

Holiday just came in on the West Coast. Candles, Latkes and Brisket. Yes Indeed. Who knew? Wallies celebrating Hanukah. Chag Sameach! By the way, a good wife of any background is a blessing, but a Jewish wife ... ah la creme de la creme!

End of Issue

@ November 17, 2008 10:53 PM in Common Venting of Condensing Boilers

After a brief cost/benefit analysis and much good input from Wallies....Installed a new pair of vent pipes and vented the boilers according to mfgrs specifications. Could not see any good reason to do otherwise. Thanks All.
