@ April 1, 2011 6:23 PM in Installing a new systemThat my post would turn on the lightbulb upstairs but guess not. I'm with Ice.
@ April 1, 2011 6:21 PM in Viessmann Guy / Harrisburg, PAWhat's the problem? I'm 3 hrs away and willing to help..Is it a new Vitodens or the previous version?
@ April 1, 2011 4:11 PM in Installing a new systemHere's how the warranty would work.
I warranty my joints from leaking and that I properly piped and installed the boiler per the mfg installation instructions. You own the rest. Rest meaning any part that you purchased to include the boiler. So if you would like me to install it for my current labor rate sure but you should also know that any time I have to spend running to go get a part or replace a part that you provided that isn't right you are paying for my time.
@ April 1, 2011 10:49 AM in Vitodens LLH SensorI just called to get a price on these and only in the 1-1/4" version....Way out of the ball park when comparing it to the competition such as Caleffi. Caleffi comes insulated...
@ April 1, 2011 7:59 AM in Vitodens LLH SensorI don't use the Viessmann LLH much. I use the Caleffi on the 200's. It comes with insulation and has a port to thread in a 1/2" honeywell well to insert the sensor in it. I just don't like the air removal on the Viessmann header. The first version was terrible and last year they made the change to the newer LLH but still would rather have better air removal then what the Viessmann header has in it.
Ice I have them in stock with the insulation kits if you need to get that job closed up. Drop me an e-mail.
@ April 1, 2011 7:37 AM in which pumpTake a look at the Taco Zone Sentry's. Ball valve style, 3yr warranty, 12vlv's on a 40va transformer. Much better flow rate through them also.
I would also tell you to use the Taco Bumble Bee ecm pump but it's not on the street yet. I just recevied my test pump yesterday. It's nice, stainless steel housing, ecm motor and I'm believing that pumping using Delta-T as a parameter is better then delta-p (Alpha or similar).
@ April 1, 2011 7:09 AM in Vitodens LLH SensorStrap it on the supply side pipe going out to the system. Better yet install a copper x Female tee and use a 1/2" short honeywell well to slip the sensor in.
@ March 31, 2011 7:14 PM in indirect or not?I'm not meaing nor intending to be rude but your concerned that an indirect may not be efficient yet you have a 100,00 btu boiler heating 1700 sqft. Your concern should be reducing that load because that boiler is WAY oversized. Do a heat loss and you will see that you only need half or less. That 86% is a not a true statement as to the "Heating Systems" efficiency. It only relates to the burner efficiency. So what that your making 100,000 btu's at 86% efficient. In reality the system is more like 50%. All that extra energy being made that doesn't need to be made is going up the chimmney...This is the main reason why a cold start boiler is more efficient. Reduce chimmney loss.
@ March 31, 2011 7:03 PM in Buffer TanksWhat are the modulation rates of the boilers and will they be cascading? Whose mod/con are you using?
@ March 31, 2011 12:32 PM in which pumpWith whether to post it or not. I felt bad, since he has already purchased the boiler and has a contractor helping him with the install, I thought it was the right thing to do. I'd rather see him do it right then end up in trouble which from his post is where he is heading.
@ March 31, 2011 7:03 AM in which pumpI would be using a properly sized pump like the Grundfoss Alpha, Taco VDT or similar pump and zone with valves. I left you a present attached.
@ March 30, 2011 10:12 PM in Can't get warmYou said it feels cold. What is the thermostat reading in the room its in? Is that the room that feels cold or is it another room?
@ March 30, 2011 7:13 PM in Indirects?Since were throwing choices, felt might as well throw the mack daddy out there.
@ March 30, 2011 3:38 PM in Indirects?This....The 80C
@ March 30, 2011 10:59 AM in which pumpThink of what it will cost to fix your budget gone job. Spending a few dollars to pay someone with experience in what you are doing to consult for a day will be miles cheapier..
Where did you purchase the TT from? There is an applications manual with the proper piping diagram. Have your contractor friend go to the supply house and get it. You said you need the CH pump..CH pump would be the zone pumps. Indirect would get piped on the primary (boiler) side not the secondary.
@ March 30, 2011 8:39 AM in help with controlThey can change the thermostat to 90 or 50 and are only going to get the btu output of the rads based on the curve that is set in the boiler. That curve could change all day and all night long. Why overcomplicate. Just use basic programables and set them up. I would not set back more then 3 degrees. If you want to keep them out of them then buy therms that you can lock them out of.
@ March 30, 2011 7:29 AM in ecobeeIt's nice and easy. Haven't used them on a multiple job though...I use the Wirsbo Climate Newtork which also gives internet access. I think the Ecobee is an easy sell. Consumers love to play with their phones and I-Pads....The only isse I see with vacation homes is that your done if the power goes out. Would be nice to be able to ping a satellite feed as back-up instead of relying on a modem at all times..
Everyone has cell service. If there was a port in the interface to plug in an air card that could be used as back-up it would be a home run..
@ March 29, 2011 9:39 PM in Replacing Gas Boiler QuestionsAt the Burnham ES2. I'd question the heat loss of the basement. If 4 ft of it is under ground no way it's loss can be at the 1st floors loss. Boiler should be sized for the heat loss. You don't deduct the efficiency of the boiler gross to match the heat loss. If you want to be conservative use the DOE rating if the boiler is in a conditioned space not the net..
@ March 29, 2011 9:31 PM in Curious as to whatThe boiler will just sit there and look at him and do nothing with no error codes. If you don't make the flow switch it does nothing but look at you and say..Hey, read the directions I need some foreplay...
@ March 29, 2011 8:06 PM in Combination heating and domestic water boilers?Sold a few. Mostly for those jobs where the builder wanted cheap but stilled play on the high eff angle to put a few bucks in his pocket while beating up the installer. I do have to say haven't had any problems on the dozen or so I sold. Ask me in another couple years though.
I think the target is going to be exactly what this contractor is doing. Condo, Apartment type applications where they want the cheapiest they can get while riding the efficiency card to a few extra bucks. The installers are at the mercy of bid and spec generally on these type of projects. I don't see these as being promoted to the residential market but you never know.
I agree with you, looks like a kickspace heater on steriods..
@ March 29, 2011 2:01 PM in Combination heating and domestic water boilers?It's there anwser to fighting off the tankless mfgs. It is 96%, rated as boiler but like everything, you get what you pay for...
@ March 29, 2011 1:45 PM in Combination heating and domestic water boilers?May want to take a look at the attached. While, this is not made by them the mfg across the pond sold a few hundred thousand of them last year from what I was told. Have seen it live, pretty quite and easy to service.
