@ March 7, 2014 6:56 PM in Steam traps?If you go on the Mepco/DB web site you can find the rep in your area. We bought some of their vacuum pumps last year from a rep in NY
@ March 4, 2014 9:35 PM in Carlin Gas Conversion or new oil tank?I would do the oil tank if it was my house base on your timeline.
The boiler is pretty old you could convert it to gas and then use the conversion burner over if the boiler failed if you decide to stay.
@ March 4, 2014 9:28 PM in Unequal circulators in seriesI don't think so. When the 2d pump is brought on the flow will increase but so will the head on both pumps so the original pump has its flow reduced by the rising head. If their the same pumps they should pump equally but not at double the flow of one pump.
Remodel has it right
@ February 28, 2014 7:18 PM in Low pressure steam, but long burner cycleAs the others said if it's heating the house it's probably ok. Do you have to add much water? How often? That could indicate a leak.
It,s possible you need a little increase in the firing rate but longer cycles make for smoother operation as long as fuel consumption is normal for the house I would probably leave it as is.
@ February 28, 2014 7:08 PM in Pressuretrol IssueI wouldn't recommend screwing around with a pressure control put on the 4 lb vapor stat. Keep the PA404A as a back up safety limit.
You shouldn't be screwing around with a limit control, that's a safety control. If you cant adjust it to control as you want (and you wont be able to with a PA404A) Replace it or keep it as a limit.
@ February 28, 2014 6:59 PM in Pickup factor. Help me understandSteam cycles up and down (at least in a house job)
Every time the boiler shuts down the steam is condensed back into water very quickly. The radiation will stay hot for a while. The piping with not as much mass doesn't hold the heat as well.
When the boiler starts again it has to reheat the piping again. Some of the steam is condensed back into water without getting to the radiation so it does no useful work other than reheat the pipe (which is the pick-up)
Jamie's example of a car accelerating is spot on.
You are correct in that the pick up factor is seen as somewhat antiquated by some.
No doubt we need to have a pick-up factor. 1.33 may be overkill for some jobs but needed on other jobs.
It's a judgment call. Will the boiler ever have to pick up the piping and a cold house at the same time??
@ February 27, 2014 9:23 PM in Could this be Steam Boiler or the Oil Burner's problem?The flame should go out immediately when the burner shuts down. He changed the pump which controls the shut off pressure which could have been causing an after drip or after burn
(I am assuming the burner does not have a solenoid valve)
If your still getting an after drip or after burn you need a new service tech. Wrong nozzle, wrong spray angle or burner gun assembly pulled back to far or not properly set would be my guess.
@ February 22, 2014 8:51 PM in Clocking My CGiI would trust the gas meter. Believe me, the Gas Co doesn't give away free gas. Your gas pressure is probably off a smidge. Your firing the boiler at about 93% capacity so your output is roughly 105,000.
If you had the instruments you could get the boiler efficiency but what you are doing will give you accurate results. You could double check it by doing a heat loss of your house but I feel you are in the ballpark.
If you go mod-con the boiler will modulate to match the load anyhow...you just have to be in the range of the boiler you need.
@ February 20, 2014 9:22 PM in How to get a oil burner installers lisence NYCI don't know anything about NYC but most jurisdictions will:
Check your qualifications
If you qualify.. let you apply to take the test
if you can prove you have an equivalent out of state license.
that's how I got my CT. E1 Master electrician and S1 Heating cooling Contractor. I was licensed in MA. first.
@ February 20, 2014 9:12 PM in Not Enough Radiation?not enough, radiation, insulation etc. Also Ice has a point about the space between the convector and the inside walls of the enclosure it looks like their may be to much space. the enclosures should be insulated and metal lined.
having the opening on top is better for the stack effect than in the front. is the return air inlet far enough below the convector inlet?
Also the enclosure grills (expanded metal) try removing them inlet and outlet and see if it improves the heat. They may have openings that are too small.
@ February 19, 2014 8:04 PM in friction lossAt 50 gpm I came up with 4.66 ft of head/100 ft for 2" pipe.
After converting the fitting footage to ft of pipe the total equivalent feet came out to 919 ft including the 710 feet of pipe.
919 ft @ 4.66/100 ft =42.8' of head. the fitting chart I had showed 8.5 equivalent feet for a 2" screwed 90. This seems high to me.
What do you guys show for a 2" screwed 90?
@ February 15, 2014 9:22 AM in Steam return pipe leakA pipe repair clamp that bolts around the pipe with a red rubber gasket will hold out till spring.
You could also use a couple of gear clamps (hose clamps) to hold the gasket.
Spring 6 weeks to go!!!!!!!!!!!!!!!!!!!!!
@ February 14, 2014 7:55 PM in Heat gain in computer server roomTypical comfort cooling load is approx. 80% sensible and 20% latent heat. Not so In a server room the biggest load is the equipment which is entirely sensible load. As a result the equipment has no problem running enough to remove the humidity. If anything the room may be to dry and humidity will need to be added.
We have a ton of small server rooms in our area and the small ones are typically done with ductless splits.
@ February 12, 2014 8:50 PM in Heat gain in computer server roomIt will be fine. I think your electrical load is accurate. You have some room for future expansion.
@ February 8, 2014 8:51 PM in questions to ask for new boiler quote?a QUALIFIED heating contractor can do this.
@ February 8, 2014 8:29 PM in I don't like my new boiler! oh noWell that would suck having to replace it.
Was the burner set up properly with combustion test instruments?
A smaller nozzle and down firing may help if approved with the boiler/burner you have.
Yes, you could enclose the boiler in a room and soundproof it. Don't forget to have provisions for combustion air and maybe ventilation
@ February 8, 2014 10:16 AM in old furnace gas conversionNo brainer. Not worth the conversion. Toss it out and put in a new condensing furnace
@ February 7, 2014 6:59 PM in Universal Brick Steam Ovennever worked on one. I would think poor combustion and mixing at the burner head could be a problem with all that draft and not much air down the blast tube.
Also I would think poor ignition, maybe that's why the Z dimension was messed with. Again not much air down the tube. Can the draft be reduced?
just guessing.......not much help
@ February 7, 2014 6:45 PM in Modine HW Unit in GarageBrazed plate hx is pretty cheap. Glycol it and a small expansion tank. Then you don't have to worry. you want to be able to go on vacation and not worry about it.
@ February 5, 2014 7:49 PM in Oil to Gas conversionI have to agree with Steamhead on the burner issue. I would much rather see a power burner than an atmospheric.
Guess I am just a power burner guy. A wet base boiler with a burner is going to be more efficient than an atmospheric or an induced draft.
@ February 5, 2014 7:36 PM in Singing diverter-tee systemtry and determine if the noise is when the circulator is running? when the burner is running? or both.
Rattling pipe hangers, vibration from pump transmitting through system?
@ February 5, 2014 7:29 PM in Steam boilerAs Jamie said we need more information.
You could have:
a leaky boiler above or below the water line
a dirty boiler causing the water level to bounce
a leaking underground return
leaking air vents or other leaks
partially plugged low water cutoff connections
and the list goes on.....................................
