@ January 13, 2014 8:59 PM in 66 degrees on first floor, 78 on second - how to adjust?of the guys at work had the same problem with his one-pipe system during the deep-freeze we just had. I made a copy of an EDR chart so he can survey his radiators. He is also drawing the house and adding the measurements ,so we can do a heat loss.The house is probably 1920's vintage, but he said something that bother me. He said the downstairs is all open, room to room, which suggests a lot of remodeling has been done, and maybe radiators removed. We shall see.
@ January 13, 2014 8:22 PM in Wiring question, combining multiple zones in a 504EXPIn the future, you know what to do. For the present, turn the control back over to the boiler.The manual gives a maximum amperage combined for boiler and circs.
@ January 12, 2014 6:17 PM in 2nd floor balmy with baseboard heatFor that configuration, the spacing of the tees means nothing, as far as pri/secondary piping.
@ January 12, 2014 2:48 PM in help upgrading hydronic systemSign up for Taco FloPro University....It's free, and they have online tutorials.
@ January 12, 2014 2:39 PM in Hot water baseboard heatingI believe Chris has posted a link to a TRV with a bypass, in the past. BBHH....the TRV would allow you to set your bedroom temp to whatever you want without cooling the whole house.
@ January 12, 2014 9:43 AM in What does term "Knocked-Down" mean?did your boiler fail in 8 yrs?
@ January 12, 2014 8:44 AM in whats best way to clean hard to access radiator fins?The most efficient way I have heard of is compressed air and a shopvac.You would have to play with pressure and containment to avoid trashing the whole house, and I suspect you would have a perfect procedure down by the last baseboard. But, at least you'd be that much ahead for the next time.
@ January 12, 2014 8:27 AM in "Normal" pressure and temp?The maximum hi-limit setting for that hydrostat is 220*. What is the hi-limit set for? If the boiler will fire above the hi-limit setting, it needs immediate attention,
@ January 11, 2014 5:33 PM in Hot water baseboard heatingI don't think we were focusing any longer on setbacks, but rather the systems inability to ever reach temperature, at design day temps. We missed the opportunity to check the temps at the radiators during the cold snap. So, you have concluded that there is just not enough radiation Gordy?
@ January 11, 2014 2:58 PM in Hot water baseboard heatingHope there's a flow check in that circ for the DHW.
@ January 11, 2014 2:07 PM in Hot water baseboard heatingThis is getting ridiculous...It takes my computer about 30 seconds just to load this page.
@ January 11, 2014 2:05 PM in Hot water baseboard heatingThey read 180* to 48000 btus of radiation, based on slantfins rating and got a DT of 20*. Can't we assume 4.8 gpm, which puts the head at about 9 based on the 007 curve?
@ January 11, 2014 1:54 PM in Slow the Flow?I see some late nights in your near future. Watching the tutorials on FloPro University.You will be amazed....do, check it out.
@ January 11, 2014 1:23 PM in Hot water baseboard heatingBased on 600*lin/ft @ 180*...They have 33k+ first floor and 13k+ second floor?
@ January 11, 2014 12:33 PM in Hot water baseboard heatingQuestions and answers that just don't add up on face-value.The OP needs TRVs in their bedrooms, so the setbacks can be avoided.I think that as Chris said, there is something wrong with the math here, and the math doesn't lie. If the unit was in "Boost" mode for the readings, it was in boost mode for the time they could get heat to the house.
@ January 11, 2014 11:48 AM in Slow the Flow?What type of boiler? If cast iron, is there any protection from low return temps for the boiler? What type of controls are on the boiler? What type of emitters do you have? Is there enough, based on the heat loss? What kind of flow do you need vs. what you have? I'm sure you have these answers readily available....nah....just kidding. The guys here can help you with these questions.You can sign up for Taco FloPro University, it's free and they have video tutorials that will teach you everything you need to know, if you choose.
@ January 11, 2014 9:25 AM in Hot water baseboard heatingBoiler is large enough based on the heatloss. There is enough baseboard, based on the heat loss. You can get 180 degree water from the boiler(running ODR) at 25 degrees, which(possibly) implies an incorrect design day parameter, but not one that should have created the problem they had. Just observations....
@ January 10, 2014 10:25 PM in Hot water baseboard heatingThere's a problem with the ABCD readings. The system supply reading, exceeds the boiler supply reading.
@ January 10, 2014 6:05 PM in One-Pipe Main VentingNot all recommendations are alike. When you get a recommendation here, it is because of skills proven, time and time again. Joe is always showing pictures of his work here, and it is always meticulously proper. He takes no shortcuts on quality, and when he's done the system will operate perfectly. As it was intended to.He is among a handful of steam pros in the country that could be trusted to restore a more complex steam system to its former glory.The problems with your system are not that complex, but need attention. That's all I've got to say.
@ January 10, 2014 1:40 PM in Volume of water per inch of height in gauge glass (Burnham)?the boiler until the water drops an inch in the sight=glass, and see how much that is.Use a bucket.
@ January 10, 2014 1:09 PM in How do you determine temp settings for an outdoor reset?Is the temperature sensor calibrated, per the instructions?
@ January 10, 2014 12:51 PM in One-Pipe Main VentingYour system has been knuckle-headed for years. Your installer just carried on the "not-so-proud" tradition. You need a steam pro. It is beyond band-aids at this point.
