without knowing any of the details.....

@ September 3, 2013 2:13 PM in Radiant heat and condensation worries

Yes, you should have mixing and boiler protection.  Hopefully you or someone designed the whole system for radiant, and you'll know the temps you'll need.  You'll be below 140 for sure and will need pri/sec piping or a 4 way mixing valve, for starters, with outdoor reset. I wouldn't raise the temp just for the one room of baseboard, without doing the math.  If your lucky the baseboard is oversized, (or you could add more) and it wont matter.  Splitting it into its own zone may cause short cycling.

That looks interesting. What's been your experience with it?
1. Product availability/lead time?
2. Company support
3. How many jobs have you done with it?

Thanks
Steve

few thoughts to the OP...

@ August 25, 2013 9:50 AM in Radiant Floor Help

"...Warmboard and Raupanel, but they seem awful expensive for a bit of convenience."
Warmboard is easily the way to go.  When you factor in everything you are going to need, from the boiler, tubing, manifolds, circs, etc., Having an evenly heated floor makes it all worthwhile.  The warmboard will allow you to use less tubing and provide a great base to replace hardwood flooring.  Either way your insulating underneath. 
I think the idea of buying 5/8" plywood, installing it and routing grooves, is a horrible one.  You just wont get even distribution at all.  It just wont work.
And running plates underneath the subfloor, in the basement, then running the tubing, with all the pipes in the way...very labor intensive. 
The warmboard will go in just as fast as the plywood method--without days of routing.  You will still have to do some routing with the warmboard, It's the best way to go for your situation, and the added cost for the superior benefits is well worth it.
Just remember to have it professionally designed (warmboard will help with that).  You'll need higher temps under the carpet, and very controlled temps under hardwood.  Batt insulation will be fine.

Few questions...just wondering

@ August 21, 2013 10:14 PM in New Carbon Monoxide Studies

1. Is there a link to the study?
2. What rating was the drywall? Did the study include double drywalled, fully fire-taped, all penetrations sealed?

How bout...

@ August 18, 2013 4:49 PM in Small 3/8" PEX manifolds

Watts?  I thought I remember the manifold that takes a 3/8 or 1/2 pex, depending on the compression rings/adapters.

My thoughts

@ August 13, 2013 9:22 PM in Heat Loss calculation anomalies

What software are you using? The reason I ask is because they do things different ways.
1. I would treat the first floor as 2 rooms. Remember in those spaces, the half wall calc in both rooms would show as interior walls.
2. I think you'll get plenty of radiation on the half wall. (89 sq ft). How bout a nice properly sized powder coated radiator?
3. I would just count the second floor hall not the steps. It won't make any difference.

Quick question...

@ July 30, 2013 4:52 PM in Radiant Ceiling spacing effects

Are you sure about that heat loss number?  Seems high for 99 sq ft.  Are the walls, and ceiling not insulated?  Did you calculate insulating the ceiling before you put the tubing in?  Does this office have 3 exterior walls and/or lots of large windows?
If all of that is correct, then 56 btu/sq feet will require a pretty high water temp, if it's even do-able. 

There are plenty of posts on this here.

@ July 30, 2013 4:44 PM in Oil Line Clog & CO2 Cartridge

Yes, of course it could, will, and most likely did.  There's just too much pressure in a cartridge.
I, and many others here will tell you, never use a CO2 cartridge to clear a leak.  If I cant clear it with a hand pump (which I almost always have), I replace it.  My thought is if its that clogged, the tank is going to need to be treated, or cleaned, or even replaced, and hopefully you have, or will move, the first filter to the tank.
One Wallie here, Icesailor, has told us he uses a compressor with very low air pressure with much success.

Are you looking for.....

@ July 19, 2013 8:17 PM in on line parts pricing

Flat rate pricing guides? Just google that and you'll get plenty of hits. Online or printed books. But it's a big industry now, and it's definitely not $299 anymore.
Theres also apps for your iPhone/iPad, but the cheaper ones aren't really modifiable

Hmmmmm

@ July 15, 2013 9:58 PM in Taco ZVC404-EXP Problems

I hope your somewhere cold. Without working thru all the wiring with a good meter, it's hard to say. My initial feeling is unless it was struck by lightening, a power surge or hit by water I'd say no. If all the wiring checks out, I'd move to checking the circ. Is your boiler also do domestic hot water?
Is your AC t-stat tricking your heat t-stat to come on? (If you have separate stats).
Just need a full checkout before replacing the controls.

a while ago, sorry, forgot to update

This is gonna sound rude.........

@ July 11, 2013 5:42 PM in White Smoke after shutdown

But if you're a "licensed oil burner tech" you should know how to test & how to correct this obvious/simple problem....
"...the oil vendor, the company that installed the furnace, and the Olsen rep at the home....No problem was found..."
That's a lot of incompetent people to look at a simple furnace problem....
BTW,  "...I did a combustion test with a digital analyzer before the fan came on and after the fan came on to verify there was no heat exchanger leakage (which there wasn't)." 
 This doesn't prove the heat exchanger isn't cracked/leaking.  A visual inspection is still required.
Sorry, but based on your post, I just don't feel comfortable telling you what to do.

Are you sure....

@ June 30, 2013 6:45 PM in asphalt laminated kraft paper and staple up radiant floor heat

Are you sure that your..." just discovered that underlayment is asphalt laminated kraft paper (with some fiber reinforcement)."..isn't asbestos? Pretty popular back in that era. If so, just wondering if that would/could act as an insulator.

That's one way...

@ June 22, 2013 9:27 AM in Multiple ODRs?

The contractor has a good solution, ODR is better, if it doesn't conflict with the main control (shouldn't)...but their are better ones, that require some repiping, and different controls. 
How is it piped? Are both radiant zones using zone valves?
What are the design temps for each zone?
What's the floor covering on the staple up?

For starters......

@ June 18, 2013 10:13 PM in Triple Aquatat RElay

Your low limit is set too high. The thermostat needs to be wired to T-T on the aquastat. The jumper on the primary control is fine.
But you should have the system checked out, completely troubleshooting the triple aquastat. It's also possible somewhere in that wiring mess something is mis-wired or a loose connection

If your not drywalled yet.....

@ June 8, 2013 7:12 AM in Heat loss Calc, correct wi ndow measurments

The easiest way I can think of to explain, just measure it like you were fitting it for mini blinds, to cover the glass.  It's more important to get the right type of window (r value).  A few sq inches wont matter

Could be a number of things....

@ May 31, 2013 11:12 AM in Air Lock

Was it working before you started working on it? If so...
1. Check for proper installation of pump gasket, if its a Suntec there's a right and wrong way to put it on.
2. Check gasket & seal of oil filter.  If the gasket isn't installed and sealed tight, it will suck air all day.  Open it back up.  I usually wipe a little heating oil around both sides of gasket. 
1 & 2 are pretty important, but even more important if its a lift job vs. a gravity job.
Then you're going to need to power purge it.
If that doesn't work, let us know, although at this point you're going to need a pro..

@ May 22, 2013 10:50 AM in whatever happened to the development of a steam assoc.?

Yeah they are relatively close, in size, location (a few blocks), original windows,and remodeling (almost no remodeling). 
The other site is hvac-talk.com, which most everyone knows, but they hardly get any posting in oil or hydronics.  But they are big on vetting, and locked areas for tech to tech chat.
As we all know, this is still the best place to be :)

Another suggestion....

@ May 22, 2013 10:41 AM in Order of Catagories on the Wall

Hi Dan.  I wondered what you, and others thought about the following:
On posts (and who knows how long/far a post will go) , it seems to me it would be better if people can only reply and attach their post at the end of a thread, instead of inserting comments in between older posts.  It's a little hard (for me) to sift through an old post, looking for the newest comment, especially post that have hundreds of comments, and figure out who is responding to who (or what).
Almost all blogs & websites only let you post at the end of a thread.  The person responding usually puts "@ so&so", then their comments so readers can figure out to who (or is it whom) the poster is responding 
Just wondered if anyone else had problems following along sometimes.....maybe it's just me.
Thanks
Steve.
