@ March 5, 2014 7:50 PM in Short cyclingClank why are you cycling on pressure before satisfying the thermostat? Are you recovering from set back? Is the boiler oversized?
@ March 5, 2014 7:27 PM in Why not a cut in of zero?No it actually states twice the system pressure drop. Do you have a copy of TLAOSH. If you do read chapter 2. If not I would suggest you buy the book and read it. In chapter 2 it is explained how system pressure drop is determined.
@ March 2, 2014 6:34 PM in Knocking and hammeringJWhite since you do this for a living it would be a wise investment to buy "The Lost Art Of Steam Heat" and "A Pocketful of Steam Problems". This small investment will pay itself back many times.
@ March 2, 2014 8:27 AM in Beating a dead horse.The only problem I've seen here on the Wall with IN series boilers is rotting out from excessive feed water and bad piping. Any boiler will rot our from excessive feed water or water with excessive chlorides or low PH. No brand of boiler is exempt. The boiler can't be blamed for water quality or system problems. I don't know why Burnham won't offer their Megasteam with a gas option. How many other companies have certified their oil boilers to be used with gas? Only 2 I've heard of are Slant-Fin and Smith.
@ March 1, 2014 1:28 PM in Beating a dead horse.All companies are in business to make a profit. Burnham already offers a gas steam boiler, their Independence Boiler. What is Burnham's market share with their Independence boiler?
Maybe by offering the Megasteam with a gas gun option the market share they would gain would be at the expense of their Independence boiler and possibly their profit margin is higher with the Independence then the Megasteam.
@ March 1, 2014 11:16 AM in Pickup factor. Help me understandThat study was a very interesting read. With the boiler a 130 degrees it took 5 minutes to make steam and then on average an additional 12 to 17 minutes to get steam to all the radiators at all 3 firing rates. Very slow steam distribution by modern standards. The main venting most likely needed to be increased. What would be interesting to see would be some data on the effects on a steam system that has a hot water loop sized near pickup factor. Start the boiler at 130 degrees and run only the steam zone. Time how long to start steaming and how long till steam is at all the radiators. Next start the boiler at 130 degrees but run the steam zone and the hot water zone and time everything again. Run the test a few times and take an average. Would be nice to run the test at night with about a 30 degree outside temp. With the hot water loop removing the built in pickup factor the steam would be operating at the net rating or close to it.
@ February 28, 2014 7:58 PM in Pickup factor. Help me understandChris the actual pickup will vary depending upon the temp of water in the boiler and the temp of the piping. The hotter everything is the less pick up needed, the colder more. But whatever the actual pick up is it must be met every cycle. The boiler and pipes must be brought up to steam temp before any steam gets to the rads. For example lets say it took 10 minutes to get steam to the rads and the boiler ran a total of 20 minutes. In that example the pickup was 50%. In actual btu's it would be whatever the output of your boiler is for 10 minutes. The boiler rating on the boiler are based upon 1 hours time. Rarely does your boiler run for 1 hours time.
@ February 27, 2014 7:15 PM in Low pressure steam, but long burner cycleIs the system keeping your house at 70 without any banging, hissing, spitting vents, short cycling or other steam problems then there is no problem other than maybe your boiler is slightly undersized.
@ February 26, 2014 10:01 AM in High heating bills - looking for some ideas!What other appliances in your home use gas? Did you factor them out? What temp was the thermostat set to? Where are you located it has been very cold in the Midwest and the Northeast. Was size is the boiler and what is the EDR of the attached radiators? Order the books that are available here and get the knowledge.
@ February 23, 2014 11:22 AM in loud banging after oil->gas conversion can't sleepThe steam mains running through your garage are uninsulated and running through an unheated space since the radiator is disconnected. Uninsulated pipe condenses a lot of steam and could be a cause of your water hammer. The main vents are most likely located behind the sheetrock in the finished part of your basement. Hopefully there is an access panel where they are located. Where are you located? Maybe there is a steam pro nearby that can rectify your issues.
@ February 19, 2014 6:29 PM in Last Rites?Fix the leaks or the new boiler will suffer the same fate. I have a Burnham IN-4. According to the manual I'm only allowed 1 gallon of make up water a year.
@ February 15, 2014 8:42 AM in New Thermostat really improved my steam indoor comfort levelThe rad in my upstairs bathroom is the furthest from the boiler. The runout for this rad is located near the end of a 24 ft main. The runout is about 8ft long and the riser up to the bathroom another 8ft. The fastest I've timed getting steam to this rad is 9 minutes. At 2 CPH my boiler would only run 12 to 13 minutes. Therefore I would only get a few minutes worth of steam to that rad.
@ February 15, 2014 7:41 AM in New Thermostat really improved my steam indoor comfort levelIs your temp chart for the room with the thermostat? Have you ever tried charting different rooms? If possible make a chart for the room with the rad that is the farthest from the boiler. Chris J made a switch to 2CPH earlier in the year. I tried 2 CPH a few years ago and wash"t satisfied with the results. With my FocusPro 5000 I would just start getting steam to the rads and the thermostat would turn off the boiler. Also time how long it takes to get steam to the end of your mains and check how long it takes to get steam to the furthest rad and compare to the how long the boiler is on at 2 CPH.
@ February 13, 2014 5:36 PM in Time Delay Switch InquiryThere is a man who posts under the name MarkS. He used some type of time delay relay on his system. He has since built a controller to run his system. Do you have a Honeywell thermostat? You could try setting the cph to 2 instead of 1 and see how it works. That will reduce how long the thermostat calls for heat.

@ February 9, 2014 12:03 PM in Electric heat, or infra-redI did a quick search and the electric baseboards I found were 6ft long and were 1500 watts. Add up the total length of your baseboard and that might give you a ballpark figure. Also, make sure of your cost per kilowatt hour. Divide how much your total electric bill was by the total amount of kilowatt hours used. My bill is broken down into a Service Charge, a Delivery Charge, and a Commodity Charge. All together I pay 18 cents a kilowatt hour. The charge just for the electricity is 8 cents a kilowatt hour.
@ February 9, 2014 10:50 AM in Electric heat, or infra-red1500 watts is equal to 1.5 kilowatts. So of every hour of continuous use it will use 1.5 kilowatt hours of electricity. That is most likely it's power consumption at its highest setting.
@ February 8, 2014 10:00 AM in Electric heat, or infra-redWhere I live they read the meter every month. Learn to read the meter yourself, it is very simple. Keep a daily, or weekly, or monthly log book of your reading. Then you know your actual usage.
@ February 8, 2014 9:43 AM in Idea's as to getting steam horizontally to farthest radiators at other end of house on first floor?All your going to get here are opinions from people who haven't actually seen what is going on. We know the pipes are uninsulated and in a crawl space. Are the pipes large enough to handle the connected radiation? Are the pipes properly pitched? Does every rad have its own runout from the main or do they share the same runout? Not enough info given to really give a good suggestion. If your expert opinion is to tap and add a second vent and insulate the pipes, then that is what should be done. If that is only a part of your recommendation then we don't have the whole story.
@ February 8, 2014 8:14 AM in Idea's as to getting steam horizontally to farthest radiators at other end of house on first floor?You state in another thread that JStar put in a gas boiler for you. You should have him look it over and get it fixed.
@ February 8, 2014 7:58 AM in Electric heat, or infra-redYou state that you have been keeping track of your heating bills for the past 15 years. Since you have electric heat I would assume that everything in your house is electric, meaning the stove, hot water heater, clothes dryer, refrigerator, and freezer. Do you factor out how much electricity it takes to run these appliances out of your electric bill to determine your heating bill? What is the wattage rating of the infrared heater? What is the wattage rating of the electric baseboard in your living room? Which ever is less will be less expensive to run.
