@ August 21, 2009 6:49 PM in Aluminum heat exchangersI'll leave up to you guys whether you would install this boiler or not. Weil is in the process of changing their heat exchanger in this boiler from alum to stainless. Why? They are beginning to see problems associated with the alum block ie, failures and this comes from a source that knows.
If it were me I woould be looking at Viessmanns new Vitodens 100 or 200 depending on the application. Why? Strongest stainless heat exchanger on the market. Look at the table of metals nobody elses compares. Also they have a 2 yr warranty on parts and limited liftetime on the exchanger. Nobody else has this type of warranty.
Also, it you go with the new Vitodens 200. The burner continually looks at gas pressure and gas mixtures and adjusts to fire at its optimum peak. The boiler also condenses like crazy. Your flue gas temp with only be 15 degrees higher than you return water temp. This boiler can also be vented many different ways and to over 200' away.
I haven't even gotten into the control. I'll leave that up to you. If you would like some info in it, ie, lit and manuals just e-mail me and I will forward them to you. We cannot post PDF files on this site.
@ August 21, 2009 6:35 PM in Anyone familier with using a Vitodens 200 with external DHW pump?To the back end of the web site. If so, it's there. Also, we are selling the new 200's and all you now need is to order the sensor for domestic hot water. No more pump module.
@ August 21, 2009 6:29 PM in wall hung boiler for radiantI prefer Viessmann. I truly believe it is the best wall hung on the market. Hands down it's heat exchanger utilitizes the highest grade of stainless steel vs it's competition. It has a better warranty then it's competition.
You state you need 50,000 btu's how many different water temps do you need? Is the boiler only doing the heating or also taking care of your domestic hot water needs?
@ August 21, 2009 6:40 AM in Anyone familier with using a Vitodens 200 with external DHW pump?Viessmanns DHW Kit. Suggest you get on the phone and find one. No way out of it. I don't have my book with me this morning or I would give you the part number. On the new Vitodens 200 you do not need this.
Since we are unable to post PDF's I can't post the manual. In about a 1/2hr from now I will be unavail. It is also not avail on [url=http://www.viessmann-us.com]www.viessmann-us.com but you have to be a partner to get to the back side of the site.
@ August 20, 2009 8:53 PM in Reply Posting Question.Sometimes you don't get the message you are replying to below the box I'm typing in right now. Sometimes you do get it. For instance your post that I replied to is not below this box. The last post I replied to was. That was a feature I liked in the old wall. That way you could reply to the posts questions and follow them. I'm like you phone rings, one of you children ask you a question and the next thing you know you lost you train of thought. So now I keep 2 tabs open for this site so I can go back and forth to re-read the post. It's a pain.
@ August 20, 2009 7:50 PM in old home retrofit emitter designhe needs to give more information on. Could it be the height that's a problem. What's stonger or weaker have anything to do with it if you can overcome the heat loss that he hasn't done yet. While the panel board only puts out 205bts at 180 degrees unlike fin-tube at 590/600 you can reset it a whole heck of alot better and have better zone conrol (meaning comfort) than the fin-tube. I still don't believe that there is no base moulding going around the perimeter of the room. I would like to know what total footage of base moulding is going in the room. The panel board will work much better with his exisiting system the fin-tube.
@ August 20, 2009 7:42 PM in Indirect heat lossI take it this unit qualifies for the federal tax credit. So start there. Also how about the fact that the boiler is OFF in the summer months. No need to heat up that boiler. If your unit is like the Noritz we have had a huge success with, the burner modulates. It only makes the hot water you need when you need it. No standing pilot like the boiler (if that is the boiler installed).
You have to sell the convience while showing savings in terms the customer can understand. Calculating btus' and trying to get someone that doesn't know what a btu means is like when DNA evidence first started. People get overwhelmed and tune you off. They can see that their boiler is off in the summer time and can grasp that. They can understand the instantaneous only comes on when you need water because they can see that and you can show them the pilot doesn't stay on. Just my two cents.
@ August 20, 2009 1:27 PM in Looking for suggestionsWhat size, and is this a hot air furnace of a hot water boiler?
@ August 20, 2009 11:37 AM in old home retrofit emitter designHeat hasn't done the heat loss and maybe the room layout will allow him to use it. It was a recommendation for another product. I'm sure the carpenter is putting in base trim. This is the same size as trim.
@ August 20, 2009 9:23 AM in old home retrofit emitter designRadiant panel baseboard. The price is comparable when you take out the base moulding that the carpenter is going to has to install and it will work very well with your existing system. E-mail me if you would like more info as we cannot post PDF files here.
@ August 19, 2009 8:56 PM in Burnham ES2 Webcast TomorrowSorry such the short notice. There is a web cast tomorrow afternoon on Burnhams new ES2 85% atmospheric gas boiler. Since we cannot post PDF files I can't post the info. If you are interested just e-mail me at email@example.com and I will be more than happy to forward the info to you. I also have the installation and instruction manual. This boiler is still not listed on their web site but is in the marketplace ready to ship.
Best Regards to All
@ August 19, 2009 7:57 PM in Condensing oil boilerbut I do know that it is not a boiler that you can just walk in an purchase. To the best of my knowledge from contractors I personally know that have quoted them you must be certified by Buderus to buy them. Meaning factory trained.
Hopefully you'll find someone that has installed the boiler here.
@ August 19, 2009 7:38 AM in Under cement floor pipe for heatingasertain how you identified the tubing because at times the writing on the tubing isn't clear enough or there is not enough exposed to get a clear reading. By your pic you can clearly see that it is potable tubing. While you did pick up on this I also picked up and would be concerned that this tubing isn't sleeved exiting the concrete. Expansion and contraction will happed at the point closet to the slab thus in time possibly wearing the tubing and causing a leak.
Like I stated in my previous post...While not using oxy barrier tubing is a no,no I don;t think 10' will have an immediate impact but will over time have an effect on the ferrous materials in the system To what extent I can not tell you. I don't think anyone can..Never seen a study on effects based on length of non-barrier tubing installed in a heating system.
@ August 18, 2009 8:11 PM in Under cement floor pipe for heatingMy first question is...How did the inspector identify that tubing to not have an oxygen barrier?
An oxygen barrier tubing is required in a heating application. The reasons is oxygen can find its way through the tubing. This can cause all ferrous material (iron) in the system to start to rot from the inside out. This was 1st discovered back in the 70's in the Northwest part of the country. There, they were using poly-butelyne (may not have spelled it correctly) tubing in radiant heat applications and what they were finding was that the ferrous materials in the systems started to fail.
I don't believe 10 feet is going to cause a problem in the short/medium run but it will have some effect but to what effect I couldn not tell you.
@ August 17, 2009 8:17 PM in New Category "The Gathering Place"Would be nice to have a place just for the regulars to the site to have a place to meet, ask questions of the group, post jobs, tips, etc.
Seems like you spend to much time searching for guys with all the different categories. I know we have the RSS feed but what I don't like about it is you have no idea what category or topic the feeds came from and who posted it. I would think that the feed with have the main topic and then the replies/posts. You have to read one back out, read another not knowing what the topic is. If you only subscribed to one feed category its ok but multiples its a nightmare.
Anyone else have an opinion on this.
@ August 17, 2009 8:04 PM in residential internet controlYou could give them all that and more with a Viessmann. Gas or Oil?
@ August 17, 2009 7:58 PM in Incrasing efficiency in a oil fired boilerHere are the steps I would take.
1. Do a heat loss of your home.
2. Measure the heat emmitters (baseboard in each room)
3. Compare the heat loss of each room to the max btu output the baseboard will give you at 180 degree water. (I'm in NY so, we design for 0 degrees outside)
4. Get rid of the coil and add an indirect.
5. Add a priority zone control to control your zones. (I use Taco). Make sure your zone control is the EXP version. The plug in outdoor reset control will plug into this.
6. Add the outdoor reset control.
7. Set a heating curve based on your heat loss and your comparision of baseboard per room max output compare to the heat loss of each room.
6. Clean and service the boiler have the boiler down fired if needed based on the heat loss. Make sure you get a combustion test done.
7. Your on your way to save some fuel.
Best of Luck
@ August 17, 2009 7:11 PM in Radiant snowmelt under wood deckPlease keep us up to date.
I'm still racking my brain on the application of this project and I keep coming up with more questions.
1. In a traditional joist trak application the above floor is general a solid interconnected floor. On a deck it is not. How do we come up with centers for this project? The floor boards of the deck are not in contact with each other. How do we get heat transfer from a floorboard that has a joist trak to one that doesn't? Remember with joist trak the proper installation is to insulate directly to the plate. There is no so called "convection in the oven" (joist bay).
2. I'm still concerned with how water runs off the deck and what effect water will have on the joist traks over time. Sames goes for the insulation. Once it gets soaked will it inhibit heat transfer.
3. I am going to assume that you have to insulate and close in the bottom of that deck in order for joist traks to work. The R-value below has to be higher then the r-value above for this to work.
4. Since you do not have the same mass as the other snowmelt zones of this project how do you have to have a high temp radiant curve for the deck and a lower temp curve for the higher mass portions of the snowmelt.
I really belive this can be done. Just working out the roadblocks to overcome in my head. Would love to get yours and anyone elses opinion this project. This is def one that brings out all the stops.
@ August 14, 2009 8:28 PM in Adding a water heaterWhat are you spending on fuel costs per month on that old boiler?
Alot of contractors offer financing programs?
What you would save on fuel costs would probably pay for the boiler. You should really look into it. What would hurt..I'm only saying you should look at all your avenues before crossing the bridge.
We use cold start boilers all the time now but without seeing the condition of your 1930's vintage I would not recommend anything to you besides looking at replacing it. That would be giving you bad advice and that's is not what we are here for.
At the least you need to bite the bullet, pay for a service call and have a qualified heating technician look at the boiler before you decide to do anything to it.
The experience you went through today should show you the light I hope.
Best of Luck
@ August 14, 2009 8:19 PM in Rember my passwordCan we get a "remember my password" box added in so we don't have to always log on. Even it I don't log off but leave the site I have to re-enter my user name and password.
Also, when clicking on a RSS Feed and then reading a post when you hit reply you have to log on with your user name and password. Can you make it so when we click on a post in the RSS feed that it directs us to enter it then versus after we ready and want to post. This way we are already logged in the site before we get there.
@ August 14, 2009 7:59 PM in Adding a water heaterI would say that the savings from installing a complete new system today would pay you back what you will spend in 2 years plus in fuel!
It's time to get out of the 30's and into 2009. Sorry but reality hurts sometimes. Its time to replace that boiler today vs in the middle of Jan when you can't get a good contractor and your stuck with the guy waiting for the phone to ring.
@ August 14, 2009 7:46 PM in peerless ec-06today and tried to contact Peerless but nobody in tech picked up after about 20 minutes waiting I hung up.
My concern was not that it couldn't be done because it can. My concern was that you have a 3 year old boiler that carries a warranty on the iron. After reading the warranty on the boiler, I believe you are voiding the warranty on the iron leaving the homeowner on his own or exposing yourself to his wrath. You are modifying the boiler with a burner that has not been tested by the Peerless Factory who have no specs for the set-up of a gas burner for this boiler. I've run across this with other boiler mfgs and that was there stance so I would believe Peerless would fall in line.
Nobody generally worries about this because most conversions I see are done on older boilers not newer boilers. I would contact Peerless to make sure this is not the case before I started converting the boiler.
