@ July 6, 2008 7:30 PM in Equivalent feet of gas pipe

Good point. I just noticed that the label specifies that the meter capacity is 250 CF/H, so it isn't big enough. Thanks for raising this point.

@ July 6, 2008 7:26 AM in Equivalent feet of gas pipe

I'm a home owner. I won't be doing the gas piping,install or combustion tuning. I just like to know all the details before getting the job done. I have had my share of untrained "pros" and by knowing my facts, it makes it possible to judge whether a pro knows what they are talking about.

The system is steam and sized perfectly. The install is just three years old.

Equivalent feet of gas pipe

@ July 5, 2008 6:34 PM in Equivalent feet of gas pipe

This house has a gas meter with 1-inch pipe feeding the house. There are three elbows from the meter to the basement with a total five foot pipe run to where a Tee will feed the pipe run to the boiler. The intention is to install a gas burner that will burn 140,000 BTU/hr. The other gas appliances burn 170,000 btu/hour if they are all running (dryer, 65K HW heater, stove/oven). So I need a total of 310K of natural gas. Using a 1-inch feed to the boiler (through a tee, two elbows and 10 feet of pipe) should do the job, but the margin for capacity is a bit tight. Can I run a 1-1/4 pipe from the tee to give me a little extra margin? Or would it have to be 1-1/4" from the meter for that to make a difference? Thanks

We do have a sooting problem. We've just trusted the oil company to do the right thing.

@ July 4, 2008 9:11 AM in saving oil--nozzle size

I find it fascinating that through this whole interesting thread, there does not seem to be any empirical facts. You would think that there might be a design engineer for one of the boiler companies that might view this site. I for one, am completely puzzled as to whether my boiler is inefficient due to underfiring (2.5 gpm) versus the recommended 6.5 gpm for this Smith Model 19 6-section. When I called their tech support, they said that it is more efficient underfired, but I question whether the person I spoke with really knew what he was talking about. With 5500 gallons used in a season, I want to make sure we are firing at the optimal rate.

6.5gph versus 2.5gph

@ June 30, 2008 8:53 PM in saving oil--nozzle size

I have a Smith 19A 6-section that is rated for 6.5gph but fired at 2.5gph because the boiler is so oversized. The nozzle is sized to the steam load. Should I be firing at a higher rate? The oil company decided what to install.

Draft control location for gas

@ June 30, 2008 8:42 PM in Draft control location for gas

I am converting a residential boiler from oil to gas. The present draft control is located on the vertical flue pipe that rises less than 3-feet to an elbow and then runs to the chimney at the wall on a four foot run. The Field Controls instructions indicate that this same location is "acceptable" but a bull-head tee is "best". I like doing things the right way, but am not sure what benefit the extra labor will result in. The burner burns 140K BTU into a 7-inch flue pipe. The new draft control uses a 8-inch ring. Any advice?

Whenever I post for the first time to this web site, I always have a Russian name and email address appear in the Author and email box of the "Post Message". This evening, [email protected] is the email address that appears. Has anyone else experienced this? It started after that big spam attack on this site several months ago. Steve

Am I asking for too much?

@ May 20, 2008 8:17 PM in Combustion analyzer

I have prepared a simple spec sheet for our anticipated oil-to-gas steam boiler changout. The final item calls for the results of a combustion analyzer test on the installed new boiler. (Does anyone care to see my spec sheet?) The first business to quote took exception to doing any combustion analyzer testing, telling me that the boiler is tested and qualified by the factory, and the roll-out switch takes care of any CO issues. Is he a mainstream, modern professional? Or should I shop around for someone more up-to-date?

@ May 18, 2008 7:56 PM in Savings with insulation

I am thinking that icycene is the way to go.

@ May 18, 2008 7:55 PM in Estimating annual fuel usage

There is an error in the formula. As the Delta T rises, fuel usage rises.

@ May 18, 2008 5:22 PM in Savings with insulation

When I said "wood-frame" I simply meant that it is made of 2x4 wood frame:-)

Savings with insulation

@ May 18, 2008 3:25 PM in Savings with insulation

I have just discovered that our wood frame facility, which used 5500 gallons of oil this past season has zero insulation in the ceiling/roof. The boiler is 40% oversized and I was planning to replace it, but now that I see no insulation, I figure that should be the first plan of action. Is this correct logic, as far as payback is concerned? Steve

Peerless v. Smith

@ May 16, 2008 4:46 PM in Peerless or Smith? Any Reviews or Recommendations?

I've got quotes from two contractors and two different kinds of boilers - a Smith Series 8 steam/oil fired residential boiler and a Peerless WBV steam boiler. I've been looking around online for reviews of either and have not seen much other than some negative reviews of Peerless because of noise issues but I'm not even sure that's relatable to the model I'm looking at. Does anybody have any knowledge of either type? Good or bad experiences?

@ May 13, 2008 8:59 PM in TRV recommendations

Is the Macon OPSK One pipe steam valve assembly with VB-18 vacuum assembly what I need?

TRV recommendations

@ May 12, 2008 9:49 PM in TRV recommendations

Can some pros recommend a specific model TRV to control some one-pipe steam radiators?

@ May 4, 2008 2:35 PM in Oversize steam boiler

I think this thread has diverted from the original question: what kind of additional efficiencies can I roughly expect by downsizing to the correct size boiler with 28 gallons less water. It will be essentially the same style boiler, just three less sections? For instance, if I use 5500 gallons this season, would I use 20% less, i.e. 1100 gallons less equal to $3,500. Then if it cost $25K to replace, I have a better sense of the pay-off. I need a sense to determine whether it is worth the investment.

@ May 4, 2008 12:52 PM in Oversize steam boiler

I have the Carlin 301 burner. I called an engineer at Smith and he told me that the old 19 is the same as the newer 19A. I read with interest your comment about a hi-low-hi burner. There is a gas version available today that has the correct capacity. Would this be beneficial for our installation? The total replacement of what today is a working boiler appears prohibitive based on the first quotation that I received. I just want to figure out how to somehow reduce our 5500 gallon annual oil usage. The gas meter is fifteen feet from the boiler.

@ May 3, 2008 6:20 PM in Transition from Oil to Gas with one-pipe Steam System (Resid.)

Insulate those steam pipes! You're wasting a ton of money by not.
