@ November 8, 2012 11:46 PM in So, we just De-Knuckleheaded nickdu's steam boiler.PART ONE
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 topicIt'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.
@ 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 PressureHigher 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 expansionIf 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 expansionI 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.
@ November 6, 2012 7:47 PM in Lochinvar Knight WHN155 boiler + Lochinvar Squire SIT040 indirect water tankThe tank and water feed are piped into the system side return before the actual system returns. Trying to visualize what pressures the pumps will see.
@ November 6, 2012 6:43 PM in Burnham P-206-W 1983 Boiler NOT Firing (no vent damper)Got a few loose wires, and disconnected wires in that relay. It could really be any number of controls that might be bad. Does the pump run?
@ November 6, 2012 6:39 PM in High COI'm having a hard time visualizing what you just described. Can you make a diagram?
@ November 6, 2012 6:36 PM in Can't get Gas Steam Boiler WorkingWell, you can try it yourself. If you have any reserve about it, don't even start. If you feel comfortable enough, we can help you here.
@ November 6, 2012 6:34 PM in How to size a colonial raditator for any given roomHow did you come up with 3btush per cubic foot? You should do a proper heat loss.
@ November 6, 2012 12:21 PM in A combustion Analysis questionMeter down on the burner shutters. That will bring your O2 down.
@ November 6, 2012 6:50 AM in Can't get Gas Steam Boiler WorkingWell, it could really be anything. My first step would be to check the pigtail and pressure assembly for blockage. Then move on to the other controls. If the sight glass is blocked up, chances are that the other controls are dirty.
@ November 6, 2012 6:47 AM in Not sure what the problem is.....Sounds like a bad zone valve. D you have any pictures of the boiler and piping?
@ November 6, 2012 6:45 AM in SANDY + Old lennox furnace = Really ColdDid you get flooded? That may not be safe for you to work on.
Where in NJ are you? I'm available to help. And your insurance or FEMA may cover the cost.
