Looking for pictures

Bruce Marshall

Hello Wallies,

For the last couple of years I have put a request here for Bad Job Pics and you guys have more than stepped up to the plate. I use these pictures in my training seminars to illustrate how NOT to do things. Now I am building a new radiant application and control seminar for the fall of 2007 and spring of 2008 and once again need some good fubars. If you have any pictures of jobs you've seen that make you go "Hmmmm" please be kind enough to post them here or send them directly to me.
Thanks in advance,

Bruce Marshall

Here are two, Bruce

Underfloor "Radiant" at my friend Sari's house, in a crawlspace below her kitchen. The contractor eventually just took it out and refunded her money.

Looks like all they had on the truck? The way it's rusting, it won't be there long.

The house is for sale and vacant. I do most of the HVAC work for the contractor/owner, so I feel confident that I'll get the call if the home inspector says anything.

As bad as it is.......

...it probably works better than suspended tube applications. ;-) Labor is a killer, though.

Indulge me for a moment, if you will.

I'm a HO who loves looking at the install pics on this board, admiring the beautiful work (clammy, Ron Jr., hot rod, et. al), and trying to figure out what's wrong with the dogs, like this one. I had to look at this one for awhile, and there are some things I don't understand:

Why are the drains on the returns above the shut-offs? Why are there drains there in the first place?
Where's the PRV? (don't tell me coming out of the right side of the one flow control.....). What is coming out of the right side of that flow control?
Two (or is it three?) supply lines, but four returns.
Is the galvanized tee in the middle of all that black iron a problem?

Just trying to figure all this out.

Nice staple up job!

You ask good questions

1. The drains above the ball-valve shutoffs in the returns are for purging air from the system. This is probably a baseboard loop system- this arrangement is very common for purging this type of system- but might be a Monoflo too.

2. The PRV is in the line that tees off the vertical copper line going to the coil, and feeds into the black tee above the galvanized one. It is light green in color instead of brass.

3. I wouldn't have used that galvanized tee- Home Depot must have been out of black tees.

4. The second line coming out of that flo-check is capped off at the top. I don't see an expansion tank anywhere, so this may have been where the tank was connected. I sure hope the safety valve was working.....

5. Two supplies and four returns are probably OK. The supplies probably split off where we can't see them in the pic.

You too, steamhead

I don't know if you post many pics, steamhead, but I always enjoy your informative posts and observations.

My experience is pretty much limited to ci rad hyrdonic systems installed in various homes I've owned. I think I see an expansion tank off to the lower left off the water feed line. I thought the green part was a Watts feed water pressure regulator.

It just occured to me that Dan's book on hydronic heating would be a good place to invest the next $100 I happen to find in my pocket.

But I guess my basic question then, is, other than looking like an install that I might do, vs. you guys, what makes this one particularly bad?

Same thing

the Watts unit is a pressure-reducing valve (PRV). That gray thing might be an expansion tank but it's hard to tell for sure from the angle- it might also be part of the model railroad display next to the boiler. The safety (relief) valve is above the gray maybe-expansion-tank. It's lying on its side, which is the first big mistake- it should be vertical, and also should be piped directly into the boiler rather than being part of a manifold like that.

The other big mistake is the circulator location- it should be on the boiler's outlet piping after the air separator (which is built into the boiler in this case) pumping away from the separator. The expansion tank should be connected to the system at or near the separator. Read Dan's book "Pumping Away" for a real good explanation of why this works better. I tried this on my own system years ago, and can tell you it works just as he says it will.

This system may have two zones, if so with the present flo-checks it would need two circs. The proper circ locations for this setup would be right under the flo-checks.

There are some other errors but it's time to let some more of the Wall's great minds participate.

Tried to send these via your regular e-mail but got rejected??? I'll try here. How's this for "workmanship" and how not to do it

How comes day dont drop dat plastic header thingy like its hot man?

lee_7

Is that against/ close to underside of flooring. I did similiar set up close to ten years ago in my kitchen ( had baseboard left over and needed heat, but only had 3 feet of usable wall.) Works great. p/s loops with a taco mixing valve. Constant circulation in secondary loop. Kitchen has never been warmer. Not the best looking system, but works great and was basically free.

Mmmmmmm . . warm air on a cold night . . .

Ted_9

Here's a mixed bag for you

The compton photos show two sides of the same room with the pipe in the back connecting the two...had a little trouble controlling the heat among a full page of other things. The monigold is a WM GV, the second in three years. Murphy....Nice radiant eh. Seng and Wulf...typical high end steam installs in my parts.
