What do you think?
@ December 4, 2013 9:37 AM in Frog Tape and IR ThermometersThanks HR. I've learned a lot from your posts and think you are blessed with an inquisitive and creative mind.
I did a test with my homemade pulled tees and a John Deere tractor that you might like. I'll try to post some pics later on.
@ December 3, 2013 2:15 PM in Frog Tape and IR ThermometersDid a lot of dismantling and reconfiguring my heating system this past summer.
Found a few things that helped me, as a homeowner hydronic addict, and thought I'd share a simple one.
Use a length of Frog Tape on your copper tubing to get a really good reading with your IR Thermometer.
Put it long wise on the pipe to get a larger target. Frog Tape seems to have almost the perfect emissivity to give accurate temp readings.
Oh, peel it off when done. The heat will make it a little gummy after about a week. Cleans off easy enough though.
@ December 3, 2013 12:28 PM in Radiant LetdownJust curious if the Tech has been to your house yet...
@ November 28, 2013 11:58 AM in The Hydronic Formula and it's limitationsGordy said: "To me its quite simple. Trvs are the throttle for the loop, responding to room temp feed back. "
What a wonderful thread this is! Good stuff.
I want to thank Gordy for leading me towards TRVs last winter. I've spent the best part of the summer ripping out my iron monoflow piping, replacing it with a reverse return 2 pipe system with TRVs.
Awesomeness. The TRVs do exactly what Gordy is saying and are almost spooky in keeping the room comfortable and at a set temp. I take that back - they are spooky. Steady heat and not the cool down, heat up, cool down, heat up.
I'm using a B&G Ecocirc Auto circulator on the secondary side of the system (thanks SWEI) and it seems pretty happy.
Put the Vario model of that pump on primary loop. Both circs drawing less than 50W. Both circs run continuously.
I'm close to happy with my primary loop, but it will need a few mods.
I'll post some pictures later if you'd like.
@ November 21, 2013 6:00 PM in Help! Unusual system design problemHi,
Unless it is there, but just was not in your sketch, you are still going to need a pump on that loop.
@ November 18, 2013 7:53 PM in Taco Bumble Bee on Mod/Con boiler ?...need to worry about keeping a minimum GPM going through a mod/con? You may slow the flow below that minimum searching for the delta t like that.
Don't know, just a hack lurker.
@ June 21, 2013 8:43 PM in DumbDan - you almost made an error more tragic than putting a Car & Driver in a Ford dealer's showroom.
On a thread titled, "Dumb" no less!
@ June 19, 2013 3:19 PM in Delta t ...... The obsession"Similarly, if one of my zone circulators died, perhaps I would replace it with an ECM one, but I guess a constant speed one would be good enough (if they made one), or one that had a speed control knob."
I'd suggest you look at the Xylem (B&G) Ecocirc 19-14 Vario. Excellent product. You can easily set the speed you need.
@ June 7, 2013 10:58 AM in Delta-P/Delta-T Part #5That is quite a claim. I've asked questions about this topic. Am I a spy from Grundfos? Wilo? Xylem? Nah. Just a guy who likes to tinker with and think about mechanical things.
Besides - if the 'competition' is going to rush to produce Delta T circs soon anyway, why would their moles question the technology?
@ June 4, 2013 10:07 AM in Buy AmericanI'm a homeowner as well. On my current redo of my heating system I have done what I can to avoid Chinese fittings. Especially cast iron fittings. A local old-time hardware store sells Anvil brand fittings and I make the trip and pay a little extra to go there to pick up what I need.
The extra cost is worth it. I have tried black iron crap from Menards and I am amazed anyone can work with the stuff. The Chinese can not even thread the fittings in the same plane end to end. If you try to use a straight coupling from China to connect two lengths of Chinese black pipe, get ready for a trip. What angle do you want them to join at? It's a straight coupling, right? Nope. Just give the pipe a turn and you can watch the free end go through a big arc. Variable angle.
I finally give up and pull out my old set of threading dies and make my own nipples by cutting up the junk stuff, but even that is iffy. The coating on the imported stuff is not a black oxide, it is cheap lacquer that flakes off. Anyway, give the scrap straight fitting to the local metal collector and go buy an Anvil coupling. Better.
It make me very sad that this is where we are at. I am taking apart about 2 miles of older iron pipe with Ward fittings and once you break the threads lose they turn as smooth as butter. We are losing our way.
@ May 28, 2013 9:08 PM in Sandy still haunts my home!Now, JohnNY, let's please hear what you found!
@ May 7, 2013 8:27 PM in Delta-P/Delta-T Part #4Hi Heatpro,
What mode do you run the Alpha on in that situation?
@ May 7, 2013 7:16 PM in Delta-P/Delta-T Part #4No need. I don' think I'm hysterical or anything like that.
I was making a comment on a company's on-line demeanor. I am a business man. I run an on-line company and I would never let anyone in my employ use a competitor as a straw man to whack at in an attempt to boost my own product or company in a web posting. I do not see that as a positive business model. We are either a good company, or we are not.
You want to attack a CONCEPT, go for it. You want to unfairly compare your dissimilar product to their's for 4 blog posts running, not winsome.
As to the substance, I didn't like this tease from last week:
"There’s one big elephant in the room, however. When it comes to
Delta-P programming, how the heck do you determine the system head
loss, especially in a retrofit?
Great question – one we’ll address next time."
Well, he really didn't address it so well in the next posting, but he says he will next week. Until then...
When someone implies there is an "elephant in the room", it sounds so juicy, doesn't it? Here's a problem that no one talks about - determining pesky head loss!
Like I mentioned, Taco's own website shows you an empirical method for measuring head loss. A homeowner can do it, elephant sitting in the room or not. Couple of fittings, ball valves and a single pressure gauge. I've done it.
If you are a pro you can install a few inexpensive Pete's Plugs and measure the pressure differential before and after the pump while opening and closing zone access. Head loss is a knowable number not a nebulous hypothesis.
I guess I'm just saying directly to John if he reads this - I love your fire. I love the music. I love the way you love Taco. I didn't like the starting tone of this series and I think a few on here have voiced similar concerns after the first posting. Please teach and don't taunt. Don't tease. Don't denigrate. Take the high ground.
You are now free To Be Cruel to Be Kind to me :-)
@ May 7, 2013 11:53 AM in Delta-P/Delta-T Part #4Chris, respectfully, I disagree. This has not been a fun series at all.
John has gone after this competitor's particular pump for about 4 posts now. The first post was full of snark referencing some anonymous internet forum. That was sad. The snark has been dialed back some, but it is obvious he has picked a certain pump for a certain lesson Delta T doubters are to learn.
Taco is a great company. There is just no need for this. If you look around the forum today you will find a positively awesome feature on Taco done by Fox News. Very uplifting.
The Bumblebee is a great product - no need to try to lift it higher by casting the competition as inferior technology. I think there are Delta P pumps that will adapt to the situation he has outlined, he probably knows that.
He finished his blog last time asking how you would measure head loss in an established system? Well, his company has a document to tell you how to do exactly that. I used the instructions with good results. It is here:
If you follow the instructions you will be able to nail the head loss pretty closely.
I get that you are a fan, and I have learned a lot from John as well. I just think something got set off a bit ago in a post about using the Bee in a TRV situation. It just should have been hammered out here, not by taking anonymous shots across blogs. Not good practice for a great company in the age of Google caching snarky comments for eternity.
This series has just made me sad. Not more or less inclined to use a Bee, but less inclined to ask open questions on this forum because I'll wonder if I'm the idiot John Barba is talking about. I know I'm an idiot, I will just wonder if I'm THAT idiot.
@ May 6, 2013 12:51 PM in Burnham has a sense of humor!"I have come to understand that fiberglass loses half of it R-value at -18f, which makes it almost useless in a cold weather climate."
Maybe, if you live in Siberia! I can't remember weeks of -18f temperatures near Chicago this past winter, can anyone else?
@ May 5, 2013 8:32 PM in Lesson learned NEVER let the wife tag along to the home showLike I did today. Removed the actuator for a casement window to work on the window a week or so ago. As I am more than capable of doing, I misplaced it. Evidently. Or the cat did? Not important, cats can do no wrong.
"Mark, do you know where the crank is?" she asks, slightly loaded for bear.
To slightly plagiarize an old John Prine lyric, I grinned just a second to long.
I found the crank.
@ May 5, 2013 8:21 PM in Thermostatic Radiator ValveDoes your system use, Joe? Do you know?
I'm 3/4 of the way through a total overhaul converting my mono flow system over to a two-pipe reverse return setup and had a few zones running with TRV's when it was cold. Very neat!
Sort of like a living organism the way each radiator reacts to its own micro climate zone. For instance, two kitchen radiators on either side of door. Set TRV's to same setting, but radiator that gets the draft from our entryway will warm and the other won't need to. Kitchen still comfortable.
Before, they were combined on a single zone pump and both would be cooking, along with a radiator in a bedroom.
I'm stoked to get it done...
