Couple Thoughts

@ March 9, 2014 11:12 AM in Pumping away ? I must have something messed up! Help

That pump will add pressure based on its curve, not maximum. You are probably
destroying that pump, which then brings us back to expansion capacity.

Is this climbing to 30 psi, a slow process? Is the whole system coming up to temp when this climbing starts?

In General

@ March 8, 2014 5:41 PM in Pumping away ? I must have something messed up! Help

I was refering to the things that had already been touched on in others posts.Beyond design considerations, look at the I&O manual, and see how much you varied. They call for the primary circ to pump at the boiler for a reason. It prevents it from cavitating. Is that expansion tank mounted hanging off the side of the pipe, unsupported? Is there any provisions for power purging those loops?

The install definately needs work, but the only things that could cause what he has, is the auto-fill regulator, or lack of circulation, or lack of expansion capacity.

So, you clocked the meter and reallized you are way underfired?

The Sorbox side is a proprietary thread? Or, straight thread? Is that a mechanical seal I see?


@ March 5, 2014 1:04 PM in New Boiler Pipings

In my opinion, it's not worth it with a cast-iron boiler. The window of allowable return temps is too small. Have you resolved the issue of lack of heat?

I just bought a new bumper for my truck, will it fit?

If the bond between the members has been broken, it's a huge issue. Like taking a cutting torch to vertical member of a steel I-beam.


@ February 26, 2014 11:55 AM in Need Help - New Gas Boiler for Steam System Problems

It looks like the system risers come off the side of the "header"( I use the term lightly). That will make for a surging spitting system, no matter how clean it is. You need some help with that system. Bring in a steam pro and let them go over the whole system. They can tell you exactly what should be done.


@ February 26, 2014 11:36 AM in Has anyone ever heard of this?

Only the upper floor in the dwelling? Maybe a clue in there. Was there any investigation into that specific case, or are they just searching for a credible accomplice?

Really Slowwwww

@ February 25, 2014 10:30 PM in Has anyone ever heard of this?

Maybe you could bring the temperature up slowly enough that the problem would not become apparent until the home warranty expires. Can we cut through the BS, and apply just a little common sense. I've driven a lot of 12 pennies into soaking wet lumber. So wet, you got a splat every time you drove the nail home.They drop the lumber load on the day they are suppose to. If the skies open up, fifteen minutes later, and no one covers the load....guess what.

And there they go!

@ February 25, 2014 5:01 PM in Gasoline from Natural Gas?

Watch the natural gas prices go way up if they go forward with that.


@ February 23, 2014 9:13 AM in Pressuretrols

      I find it amazing that they are still using the pressuretrols with the micro-switch in them. It is a horribly outdated technology. They are inconsistent, and unreliable.Using them in control circuits 35 yrs ago, they proved useless for repeatability.
        I guess unreliable is a wrong description. They will shut the system off, at some point. With the technology today, why don't they use something else?

Push down?

Closer....that's  .1 and .5


@ February 21, 2014 1:39 PM in taco zone relay constant hum sound

Joe is from Taco, the manufacturer of the relay. If he says you will not have a problem with the replacement, trust him, and give him a call.


@ February 21, 2014 12:10 PM in taco zone relay constant hum sound

We see complaints here, all the time. One of the only manufacturers that will always respond to a complaint, and go "above and beyond" to make it right, and do the right thing, is Taco. Joe, you and your company are to be commended. Here's to a U.S. manufacturer that cares!


@ February 21, 2014 11:45 AM in taking a hot water zone off of a steam boiler

At some point air got pumped into the zone. Since it is not pressurized, there is no way to get the air out. Use garden hoses to power purge it. This will deal with the issue at hand, not the ongoing problems it will have.

Porch Conversion

@ February 21, 2014 11:21 AM in Not Enough Radiation?

The thickness of the wall in the photo, suggests they may have built walls within walls. I read a posting here( to which someone from Burnham was responding) that stated that just stacking convectors produced little difference in output, because it just created interference to convective air flow. The addition of the fans would counteract that though. I don't know how you would calculate the output of the modified emitter, other than trial and error. Without a proper heat loss,there is no way of knowing whether you could get close to correct by just increasing the output of the existing enclosures.

At Best

@ February 21, 2014 10:10 AM in Not Enough Radiation?

The output of those elements will be similar to those of standard baseboards. You need to do a heat loss for the room. Try as you may, "you can't make a silk purse out of a sows ear".
