Convert the present boiler and add a gas hot water heater?

@ April 25, 2014 6:09 PM in Oil to Gas Conversion

I think your boiler is a very good candidate for conversion to gas using a gas power burner like the EZ-Gas because it should have a lot of life left in it and could last longer burning gas rather than oil. Your chimney might need a liner but that would be true with any boiler burning gas.

If your hot water needs are modest a stand alone gas water heater might be a good idea. My 40 gallon gas hot water heater only uses 5-6 therms of gas a month when the heat isn't running, it's awful hard to think anything would be much better than that.

File sizes

@ April 25, 2014 3:53 PM in eg-45 start up questions on surging and wet steam

Some of the newer cameras are high resolution and create very large file sizes, lower resolution pictures might be better. Also make sure there are no spaces in the file names.

I agree that if the manufacturers piping directions were not followed then it was done wrong. Further skimming is probably required but don't bother if the piping has to be done over. Is the pressure set to 2 PSI or less?

Bob

Use a die

@ April 21, 2014 6:29 PM in Replacement Radiator vent doesn't seat well

A 1/8" NPT die can be used to chase the valves threads. You can exert a reasonable amount of force on the vent, often the last turn is hard., I just use a couple of wraps of teflon tape.  I would never try using a wrench because you could over torque it and break something

Bob

Yes

@ April 21, 2014 6:55 AM in Skimmer valve failed!?

That is setup as a skimming port. The plug to the left would be better because it's larger but the setup you currently have should work.

Bob

Look in the manual

@ April 20, 2014 7:22 AM in Skimmer valve failed!?

to see if they call out a skimming port. It should be at about the level of the upper gauge glass fitting and 1-1/4 or 1-12" in diameter. It could be on the side or back depending on what boiler you have.

Bob

What is it made of?

@ April 16, 2014 8:01 AM in Skimmer valve failed!?

I looked at mine last week and it was fine, my 1-1/4 Watts ball valves ball looks just as clean as it did when it was installed in October of 2012 - no signs of any deterioration. I do have a threaded brass plug on it's output just for safety, I think it was only about $7.

I assume it's chromed brass but I really don't know.

Bob

Don't try to store oil

@ April 15, 2014 8:21 PM in Is my steam boiler way oversized?

for much beyond a year. The new heating oil is not stable long term so It should be used up in a reasonable amount of time.

When I installed the Smith G8 / EZGas boiler I knew I always would have the option of going back to oil if anything happened with natural gas  cost long term. I'd have to buy an oli gun and get a tank but the option is there.

Bob

Could save a lot on fuel

@ April 13, 2014 7:59 AM in High Vac Readings caused by BioFuel 20

I switched on 2012 because my tank had developed a slight weep and i knew my Burnham v75 boiler was not known for having a long life.The new boiler is roughly the same efficiency as the old and my fuel costs went down by almost 45%.

The cost of natiural gas is not going to stay as low as it is now but oil will get more expensive too; the demand for both is just too great for prices to drop. If you can get the line into the house for zero cost I'd do it in a heartbeat.

If you put a conversion burner in your present boiler make sure they do a thorough job of cleaning the boiler and chimney before and after the first heating season. They will also have to line the chimney in most cases.

Bob

Your closer to it than I am

@ April 11, 2014 10:45 AM in Vents spraying water

To my eye it looks like the pipe is reduced but I'm not there so as long as the copper is the same size as the boiler outlet that part is ok. With only a single boiler outlet being used, there shouldn't be any issue with pipe expansion issues on the casting but If you do decide to do any piping work I would suggest using threaded steel. Most boiler makers specify threaded steel pipe for the boiler header.

 The way the equalizer is tied in is not going to do much for keeping a steady waterline or making dry steam and that could be adding to your problems.

Bob

Bad piping

@ April 11, 2014 9:27 AM in Vents spraying water

thae boiler is not piped properly, The output has been reduced in size, they used copper pipe (it should be threaded steel and configured like the diagram in the manual) and the header is too low (it should be 28" above the boiler water level. I can't see how the equalizer ties in but I suspect that is wrong as well.

Bob

Take them off and test them

@ April 5, 2014 10:04 AM in Bad new gorton valves?

Try blowing through them when they are upright and again when they are upside down. Air should pass easily when they are upright but be blocked when they are upside down.

How did the air valves that were originally on there perform? make sure the radiators have a little slope so any water can flow back out of them and be sure the valve at the input of the radiator is open all the way. Next check any horizontal pipes in the basement to be sure they slope to feed any condensate back to the boiler.

If all that checks out post pictures of your boiler, the piping around it and one of the problem radiators.

Bob

Go with the smaller boiler

@ April 4, 2014 5:27 PM in Steam boiler sizing dilemma

If you insulate the piping in the basement all you have to do is select a boiler that has the sq ft rating to feed the radiation you have. That rating already has a 30% pickup factor figured in so you don't have to worry. Using a larger boiler would just be inefficient.

It sounds like the installer that told you to use the smaller boiler knows what he is talking about. Make sure the new boiler is installed per the installation manual or better and that all steam carrying pipe is threaded steel. Have the pressure set as low as possible (1.5PSI) and you should be all set. Make sure any lines that are not going to be used are capped off so no mischief can come from them and insulate any piping you can reach with 1" rigid fiberglass pipe insulation.

Bob

Alternative skim port

@ April 4, 2014 10:52 AM in Vents spraying water

I would remove the safety valve and the elbow it sits on; then replace the elbow with a T, nipple, and ful port 3/4" valve- put the safety on the top tapping and then you will be able to skim.

A larger tapping would be nice but you have to work with what you have.

Bob

Skimming

@ April 4, 2014 8:56 AM in Vents spraying water

If you have the manual for that boiler they usually identify the plug that should be used for a skim port. If you don't have the manual you can usually download it from the web, what model New Yorker is that?

Your new piping probably introduced oil into the boilers water.To skim you draw water off the boiler above the waterline by opening the capped pipe or turning on the valve. You feed water into the boiler VERY SLOWLY (2hrs for 5 gallons) and let the water trickle out into a bucket. This can be done cold and hot, when doing it hot do not let the boiler come to a boil, you want to draw the water of a calm surface. It usually takes several skimming sessions to get all the oils out.

While you have that manual open look at the piping diagram, your boiler is piped wrong and is making wet steam. Putting in a proper boiler header and equalizer would help dry out the steam.

The material on the pipes looks like asbestos, some of it looks to be in bad shape and should be removed by someone with the knowledge and equipment. After that is done main vents could be added at the ends of the mains.

Did you check that new piping with a level to make sure it's all pitched back to the boiler?

Wet steam caused by oil in the water

@ April 3, 2014 5:42 PM in Vents spraying water

The T I was referring to earlier is at the top of your diagram and a closer look shows those radiators are on the first floor and were not involved in the work that was done.

If your auto water feed is turning on to add water that is being thrown up into the piping probably because of oils in the water caused by the piping work. The only way to get rid of that oil is to thoroughly skim the boiler to slowly float the oil out of the boiler.

Does your steam main rise up as it goes away from the boiler to feed the radiator takeoffs? If it does you have a counterflow system and the returning water travels back along the main back to the boiler against the flow of steam. main vents should be added at the end of the mains to get rid of the air and cut your fuel bills.

Bob

Setback and slope

@ April 3, 2014 11:58 AM in Vents spraying water

If it was not spraying and banging before this new work (and you were doing a similar setback) you can be pretty sure the piping is the cause. I suspect some of your horizontal piping is sloped wrong and now has water sitting in it, when steam comes across the water it collapses and you get the bang. use a level and check all the piping to see if you have the correct slope on the piping you can reach. Also where the pipe Tees off on the new run how did you gaurantee both sides of the T slope back to the boiler?

Setting the temperature that far back pretty much guarantees the system will misbehave, if you do half the current setback do the vents still spray and do you still get the banging?

Bob

It's not uncommon

@ April 2, 2014 10:36 AM in Burnham gas conversion

I live just south of Boston and when i had my Smith G8 steam boiler installed with a Carlin EZ-Gas all the inspector wanted to see was a gas leak test, so some in this state just care it's done properly. You might try contacting Charles Garrity In Lennoxdale to see if he will come that far or if he know someone in the area that can help you.

What changed

@ April 2, 2014 7:23 AM in Some radiators cool down as boiler fires? (with drawing)

If it worked before and now doesn't, something has changed and we have to figure out what changed. It's been a long winter and I've noticed everything is looser because the wood has dried out more than usual.

Has anything been done that might have changed the slope of the piping? I have a radiator that stopped heating fully at one point while everything else was fine. I noticed the vent on that radiator was panting some and thought I might have water lying in a horizontal pipe somewhere. There is a short horizontal pipe on the second floor that I suspected so I raised the whole radiator up 3/4" and that solved the problem.  Old houses settle over time and what was once may no longer be so. Yours is a two pipe system but pooling water will still cause problems, go over any horizontal pipes you can reach and make sure the slopes are correct and there aren't any dips.

Do you have a low pressure gauge so you can reliably see what the system pressure is doing during the steaming cycle, is there any dip during the cycle that might yield a clue?

More fuel is used

@ March 31, 2014 7:09 AM in Thermostat question Steam oil boiler

to heat a space to 70 than would be used to heat it to 60. If you set the thermostat back at night, anything over 3-4 degrees may not be saving any fuel because it takes a lot of fuel to get everything back up to temperature.

Do all the rooms heat about the same? If they don't you may have an issue where the air vents are not doing their job. All radiators should heat at about the same time and rate. Make sure the location of the thermostat is not causing the system to shut down prematurely. Do you know what pressure the boiler is running at when making steam?

Chase down and fix any drafts and consider using an electric space heater in one room to keep that room a little warmer - this heater should be turned on ONLY WHEN THE ROOM IS OCCUPIED AND NEVER WHEN YOU ARE SLEEPING

Bob

Coming from cellar?

@ March 29, 2014 12:14 PM in Black paper lining wall of radiator

If these are on the first floor check the cellar below them as that smell might becoming from below. If you can get the old stuff out you should replace it with some sort of insulation board so the heat doesn't just go through the exterior sheathing.

Bob

Regulates

@ March 27, 2014 4:58 PM in radiators hissing from vents, one valve shooting water

The pressuretrol regulates the maximum pressure the boiler can reach, on most systems you would like to keep the pressure under 1.5PSI.

If you turn a pressuretrol upside down and look into the base of the brass fitting you will see a very small hole that has to be clear. Unfortunately pressuretrols are often poorly calibrated, if you examine the insides carefully you will see there is a very small set screw that lets you adjust the lever between the pressure diaphragm and tension spring. If you turn that set screw just a little bit you can adjust the pressure at which it trips - by small I mean 1/16 of a turn on that 0.05" setscrew.
