Where to go

@ September 2, 2014 7:24 AM in I'm thinking of relocating

Where are you now?
Any climatic requirements?
What about becoming a manufacturers rep In some new under served part of the country? That would give you the opportunity to move around a bit.
Maybe you could become Mr. Sorbox USA.--NBC

Clogged pipes

@ September 1, 2014 12:31 PM in Unbalanced Steam System?????????

Steam pipes rarely get clogged up, as they are being constantly washed with distilled water.
What does happen is the sagging of pipes, creating little waterlogged pockets preventing air from moving out of the way of the steam. Air is the enemy, it must be chased away like the raccoon from the garbage can.
When the system pressure rises above 2 psi, the vents have trouble working, and may let the air out more slowly, requiring extra fuel from your $upplier to finally get steam into most of the radiators, but not all. The fact that you have main vents is good, as the new replacements will be much easier to install. The capacity of the vents is the most important aspect of good balance. The size of the main vents, should allow for almost zero resistance (back pressure=2 ounces).
If you fire the boiler and feel the movement of warmth as the steam starts to rise, you may find a trouble area, which can be investigated, but changing the vents first makes this easier.--NBC

Worthy of study

@ September 1, 2014 1:07 AM in SUBMERGED Boilers and Water heater. What absolutely needs replacing?

There are probably a lot of people with boilers rescued from floods, whose owners, or their repairmen have revived the waterlogged boiler. This was probably done, either through ignorance of the dangers involved, or because of financial, or practical necessity. There may be a procedure which would result in a safe repair, although as it would involve replacing all the electrical components, and washing the sections in fresh water, it must be so labor intensive as to be prohibitively expensive.
It would be interesting to do some sort of anonymous survey to see the numbers of people who have had any sort of experience with this sort of situation.--NBC

Off on safety for an hour

@ August 31, 2014 9:53 PM in owner

It is probably not the pressuretrol which is keeping off the boiler for an hour. More likely it is the LWCO, or another safety. A little troubleshooting with a multimeter should show which safety is responsible. When the flame cuts out, the steam collapses, developing a vacuum, which could hold water up in the returns for that length of time, starving the boiler of its water.--NBC

Pressuretrol settings

@ August 31, 2014 10:44 AM in Cut In on New Steam Boiler??

This is a good reason to have a good low-pressure gauge, such as a 0-3 psi gauge, marked in ounces. Modern pressuretrols are notorious for their inaccuracy. Use the gauge to verify the setting for the lowest pressure you can attain, with a maximum of 1.5 psi. With a cut-in set as low as can be.
If the main vents are functioning correctly, and the boiler has been sized properly, steam will get to all radiators at the same time with a few ounces of pressure. If the boiler cycles a lot, then the main vents are probably not working, or an excessively large boiler has been installed.--NBC

Old pipe threaders

@ August 31, 2014 10:30 AM in Is buying a used threader risky?

The main problem I have seen (with the threaders in our local hardware store), is the chuck losing its hold on the pipe, and being unable to turn it against the die.--NBC

Micro pile

@ August 31, 2014 10:26 AM in weil mclain v efm boiler

I have heard that the non-electric gas valve is still available for use in the homes of members of religious communities whose teachings forbid the use of electrically powered devices, such as the Amish, and I wonder if this is true.
Even though it requires the use of a standing pilot, the storm-proof capabilities of this could be useful in areas with many power outages.--NBC

2nd floor too hot

@ August 30, 2014 6:41 AM in Unbalanced Steam System?????????

Let's assume that the radiators were all piped properly on each of the original two systems, and therefore that any unbalance in distribution comes from the inadequate venting or the piping which now connects both systems to the one newer boiler. Can you post some pictures of the piping above the boiler, and the vents?
The first step should be adding a Gorton 2 to each dry return, and as others have suggested, reduce the pressure, (my 55 rad system rarely exceeds 6 ounces).
Are there any other symptoms such as water-hammer in the house? What sort of thermostat is controlling things, and is it set for steam? Have you been setting back the temperature during certain periods of the day?
You may have inefficient wet steam reaching the ground floor, and more perfect dry steam getting upstairs.
At the end of this you may see a fuel consumption drop by a third.--NBC

Cranking it up

@ August 29, 2014 10:51 PM in Oil to gas

Any boiler with outdoor reset could be slow to respond to the cranking it up manoevre, due to the lower water temp in mild weather. Outdoor reset is definitely better "set, and forget,", rather than using any sort of setbacks.--NBC

Mysterious outage

@ August 29, 2014 10:48 PM in carrier packaged unit......electrical short...HELP

Is this a 3-phase unit. I recall something similar with our Lennox unit, where one of the phases was fused off due to a storm, and it took a lot of diagnostics to identify the problem (not by me).--NBC

Needle in a haystack

@ August 28, 2014 6:45 PM in Bryant 244-7 Series A Gas Steam Boiler

Finding old discontinued boiler sections will be very difficult. Anyone who has been keeping old sections has been doing so because he thinks they are VERY Valuable!. The amount of work to replace them , if you could find them would be more than installing a preassembled boiler.
Why not add up the EDR of your radiators and then we can help you find an appropriately sized boiler from pex supply or some such place. Do not go off the plate from the old one, but measure the rads.--NBC

Main vent placement

@ August 28, 2014 6:33 PM in What is the solution?

That looks like the boiler header, which is not the right place to put a main vent. Examine the returns, and put the vents on the end about 12 inches in front of the drop. The vent needs to allow the air to escape from all the supply piping, and the return is benefitted by air removal as well.--NBC

Sufficient steam pressure

@ August 27, 2014 10:51 PM in new burner for old boiler?

If your system is well vented, with adequate main vents, you will only need a couple of ounces of pressure. How much have you been attaining up to now?--NBC

Oil to gas

@ August 27, 2014 6:35 PM in BTU needed on Oil to Gas convesion

Is this steam or hot water? Do you have enough gas capacity?
Use the SlantFin app from their website to figure the heat loss of your house, and that will be the BTU size for heating, for hot water only. Steam systems need a different method of calculation.
For the domestic hot water load, tell us what your usage is ( number of showers, and washer runs) you do each day.--NBC

off season boiler treatment

@ August 26, 2014 8:06 PM in low pressure steam boiler - conditioning

I would say that leaving the old water in the boiler, is most beneficial. some people will overfill the boiler, and boil it briefly to remove oxygen, before the final shutdown.
if you put chemicals in the boiler, then you would have to remove them before firing it up again.--NBC

Warm skin

@ August 26, 2014 6:25 AM in Scorched Air vs Hydrocoil

If you are sitting in the sun, you will be warmed by heat waves, feeling more comfortable, without a lot of air moving across your skin.
If you are sitting in front of a hot air supply duct, you will be warmed by the contact between your skin and the air. Such a large volume of air will be flowing across your skin, that more drying will take place (think hair dryer). I think this is the principal reason for adding more humidity to the air, especially when there is a lot of infiltration of dry outside air.--NBC

Piping geometry

@ August 26, 2014 6:13 AM in Swing joints. How do they work?

A happy, and informative time can be had at the hardware store, trying out different combinations of 90's, and 45's to get an idea of how stiff piping can be made to go between 2 points without using a single straight line.
Ice, why not go the hardware store, and put some joints together, and take a picture of them so we can see what your friend showed you.--NBC

What radiators

@ August 26, 2014 6:04 AM in Heating dilemma: Recessed radiator vs cast iron baseboard

I have seen steam heat in old Florida hotels, such as the Gasparilla Inn on Boca Grande.
In your house, you could see if the insulation could be upgrades in the walls and ceiling, and leave the windows in original, but restored condition.
For a given room and it's heat loss, steam radiators can be smaller, as a result of the higher temperature of the steam, compared with hot water. So first priority is to do a room-by-room heat loss survey, using the App from the SlantFin website. This will tell you what length of baseboard rads will be needed, so you know whether they will fit into the recesses already in place.
Hot water heating will give you some options which are not available with steam, although it is not necessarily "better" than steam. Outdoor reset which is the ability to vary automatically the hot water temperature with the outdoor temperature is one feature, and less obtrusive piping in the basement is another.--NBC

install main vents fiurst

@ August 25, 2014 3:08 PM in Adding longer baseboard steam radiators

I am assuming that the baseboard radiators were sized to the rooms long ago when steam knowledge was more prevalent in your area. if that is so, then getting the air out easily from the system will result in all radiators getting a few ounces of steam simultaneously. the thermostat is probably also letting the system run longer than necessary as it is far away from a radiator.
the radiator vents will not be able to do the main job of air removal, as they are just too small.--NBC
