@ November 10, 2012 10:00 PM in mad dog here...need warm air furnace help

Recovery? I hope you aren't doing anything dangerous.


@ November 10, 2012 9:57 PM in is it safe to fix a boiler that was submerged


Seriously... Don't do it. There are a few threads here on the same topic. They're worth reading.


@ November 9, 2012 9:27 PM in So, we just De-Knuckleheaded nickdu's steam boiler.

We started at the RS opening, elbowed over and down. Spun the first tee in place. Then came up and connected the LS opening. The RS union is just for service and symmetry.


@ November 9, 2012 7:53 PM in possible blocked radiator?

Definitely a flow problem. Like you said, bleeding water gives the hot water somewhere to go. Did you calculate head and flow for the new pump? What size pipe feeds the radiator? What size is the radiator?


@ November 9, 2012 7:51 PM in Aquastat L8148E Problem

Don't do it. The gas valve will stay on all the time.


@ November 9, 2012 7:47 PM in So, we just De-Knuckleheaded nickdu's steam boiler.

Felt real good to stand back and look at this one when it was all done. Three inch cast iron brings a real presence to the room.

The only pipe we threaded was the returns. Everything else was nipples. We bring about 4 sets of pipe, and wind up using 20 short nipples.

We're going back to install a Vaporstat and to upgrade the existing main vents.

They are Tees. One is a 2 x 3/4 x 2 tee. You phrase it Run x Run x Bull.

Check this link if the pictures don't work. I'll fix them when I get on my real computer.

Nickdu had a thread here a few weeks back. Noise, and performance issues with the steam boiler. Well...the pictures tell the story.

When we left, the system was whispering along. The exit velocity went from 45 feet per second, with the old piping, to 10 fps with the new setup.


@ November 7, 2012 10:37 PM in A controversial topic

It's funny...I never have a problem finding large pipe sizes.

Hopefully, some time this winter, I'll have the equipment to thread everything up to 4" and will make custom nipples for customers and contractors. Special discounts for Heating Help users :)


@ November 7, 2012 10:34 PM in Prognosis for saltwater submerged boiler?

If you do all of the work yourself, it MAY be worth it. To pay a qualified contractor, adding to the cost, it's usually more economical to replace the entire system. Plus, if your insurance, or FEMA, covers the cost, why take a chance? I will never recommend simply fixing a flooded appliance unless a customer signs an incredibly specific contract assuming all liability from that point forward. Even then...not worth it. Somebody being hurt or killed would still be my fault. I'm the professional. I should know better.

Big pipe

@ November 7, 2012 10:24 PM in Can there ever be too much Main Venting?

We thread everything up to 2" pipe. Larger than that, we use pre-cut nipples and very careful planning. We also have about 3 times as many nipples as will be required, so we have a lot more options available than just trying to measure once and buy once. Maybe if you get some measurments, we can draw a diagram for you with pipe sizes and lengths. I see an "easy" way of at least adding one more riser.


@ November 7, 2012 7:57 PM in Oversized Boiler?

It's very unfortunate. It sounds like you did your research, but just had a bad experience. Sometimes, you just can't plan for somebody else's bad decision. It just blows my mind that somebody would even do that to a customer.


@ November 7, 2012 7:30 PM in Oversized Boiler?

Oh boy! Yes, that is GROSSLY oversized. You shouln't have even added the baseboard into the boiler size. Just make sure that the baseboard zone is no larger than the pick-up factor. What was the EDR of the radiators?

Get that boiler out, and get a FULL refund. I would not let that company back into your house.


@ November 7, 2012 3:26 PM in Resetting Steam Pressure

Higher pressure = Higher temperature.

You will save fuel with modulation. The idea is that you start in high fire, then when all of the mains and pipes are hot, you step down, because you only need to then heat the radiators or unit heaters. The main pressure should be set just high enough to overcome the highest friction loss in the system, or to lift any condensate if needed.


@ November 7, 2012 7:36 AM in Thermal expansion

If you do some very crude calculations, the pressure could have gone to about 10 psi at 40F. So, it's possible. I didn't think that would be a big enough pressure change to make a difference.


@ November 7, 2012 6:59 AM in Thermal expansion

I wouldn't think the cold return would cause this to happen. What kind of expansion tanks are on the system? Do they still have air in them? Was the water main worked on, possibly causing a spike in water pressure?


@ November 6, 2012 9:41 PM in Not sure what the problem is.....

You can't push it by hand. I use a pair of channel-locks to do it. Does the faulty zone have a lot of rust on the valve body?


@ November 6, 2012 9:04 PM in Not sure what the problem is.....

Those Taco zone valves are notrious for rusting shut. The power head may work, but the actual valve in the body won't open. Take the head off and try to squeeze the plunger down on the body.
