Looks Like

@ July 29, 2014 4:55 AM in Looking for a replacement for these....

Looks like 8 1/2x14 legal, you can find it at any Office Depot.

Sorry, I couldn't help it :)



@ July 29, 2014 4:32 AM in HVAC options for 400 square foot addition

What is the planned use for this room? Is it a mud-room? What are your expectations for the space?

Until we know the answers to the above questions, recommendations are pointless.



@ July 27, 2014 2:57 PM in Builing an addition

If you are used to radiant heat I highly doubt that you will be satisfied with the comfort provided by forced air. Quiet comfort is priceless. I love my A/c after a hot day outside, but I HATE it when I am relaxing in my laZboy and the A/C kicks on blows cold air across me. I don't have a choice with the A/C, but I would never give up the radiant heat.


What A Shame

@ July 27, 2014 2:37 PM in Burnham IN4 steam boiler piping

It looks like the installer actually TRIED to do it right. It's a shame that it needs to be re-done. If he had only followed the instructions things could have turned out much differently.

I bet there is a bullhead tee off the main just out of the photo.


The Answer

@ July 27, 2014 2:28 PM in Burner Conversion Question - Weil-McLain P-SG0-3

The aswer can be found here. You should read the entire post. If it were mine, I would do it in a New York minute.


@ July 27, 2014 1:54 PM in Another Steam Boiler Sizing Concern

In regards to the the fact that the quotes provided do not show the EDR but only the basics of the job. Most contractors will not provide the details (I.E EDR, heat loss, miscellaneous parts to be used in the installation until the contract is written). The reasoning is that if it is given to the client at the time of the estimate the price will be shopped around and someone else will get the job as they did not have the expense or possibly experience to do the initial footwork themselves.


Make Up Water

@ July 25, 2014 4:12 PM in Lochinvar sheild HIgh limit problem

Sorry about the make up water question, I was thinking about boilers. Have you tried contacting Lochinvar tech support? It could be a number of things, as I am not familiar with the unit the first thing I would do is contact the manufacturer if I went on a service call for the problem



@ July 25, 2014 2:34 PM in Lochinvar sheild HIgh limit problem

Have there been any changes to the system? Is it possible that any other maintenance personnel have "tweaked" any settings? What is the high limit aquastat set at? What is the manual reset high limit set at? Are there any leaks in the system allowing make up water?



@ July 24, 2014 2:34 PM in Time for a new oil boiler?

Maybe I'm missing something but I have no idea how the system even works the way it's piped.



@ July 23, 2014 3:41 PM in Cleaning 1-1/2" tub drain line

The only way to clear a tub drain is through the overflow with an electric snake. Sometimes, depending on the type of tub drain, the blockage may be right at the tee of the overflow and drain. You may be able to rent a snake with 1/4" cable from a tool rental company. I still use my Ridgid K-50 for cleaning most drains. I've had it for about 30 years and I bought it used! You have to be careful not to have to much cable out of the drum to prevent kinking the cable. The hardest part is getting through the trap. It might be worth it to call a pro.



@ July 20, 2014 3:44 PM in Do I need a chimney liner?

Is he going to pull a permit on the work? If not for safety, then for insurance. It is a must.



@ July 20, 2014 1:20 PM in drainback tank ideas

HR, you are a mad scientist! How on earth do you find the time for your projects? How does the PEX work as a site glass? What pressures are you putting through it? Could you explain how you "perforated" the bladder out of the exp tank?

Sorry for all the questions,


@ July 20, 2014 10:47 AM in Silicone steam pipe through floor?

What's wrong with rock wool? I've never had a problem with it. If you're against rock wool you can use fiberglass, it's good up to 1000 degrees. Rock wool is 2200 degrees and is much more user friendly in my opinion.



@ July 20, 2014 10:40 AM in Lovely Lane Methodist Church- A Steam Heating Museum

What an interesting building. It is sometimes fun to decipher all of the different decades of craftsmanship being crammed into a building (and its additions). I am surprised that the city can't supply adequate pressure to run those boilers. I have never seen nor heard of it being done but is there any way to run a gas line sized for both boilers and only hook up one (if the main can supply enough gas for it). Then when the main is eventually upgraded the second boiler can be converted? If you made the gas boiler lead it would definitely save the church a few dollars over oil (currently).


Pressure Switch

@ July 19, 2014 4:19 PM in Suitable replacement combustion air switch

Have you checked to make sure that the pressure switch is not just doing its job? From one of your earlier posts you stated that you were getting flue gas reversion. I can't claim to know anything about that brand of boiler. A pressure switch is a pressure switch though, make and break, brake and make (unless the Spaniards have created something that I don't know about). Do you have a manometer to make the proper adjustments?



@ July 19, 2014 4:00 PM in Silicone steam pipe through floor?

That was my point. If escutcheons are used, high temp (orange or black) can be used. The clear only goes up to 400 degrees (which would probably be fine). If it were me, I would just pack it with rock wool.



@ July 19, 2014 3:54 PM in radiator cover box design question

Epoxy the stone slab to the top of the enclosure and use angle brackets to secure the enclosure to the wall. I love the louver idea. The enclosure would really screw with a TRV unless a remote sensing bulb was used on the unvented side of the enclosure. However access would have to be left for TRV adjustment.



@ July 19, 2014 2:46 PM in Silicone steam pipe through floor?

If you have escutcheons around the pipes you can use any type of RTV. You could always do one rad and use rock wool around the others as a temporary air seal, see how it holds up and decide from there. Or just use rock wool and escutcheons period. That way if you ever need to disconnect anything you will not have to clean up silicone caulk.



@ July 19, 2014 12:59 PM in Silicone steam pipe through floor?

I would use clear RTV, it's good up to 400 degrees. If you want to use regular silicone caulk just look at the label for its temp rating.



@ July 17, 2014 2:06 PM in radiator cover box design question

I don't know what your budget is but granite or marble work very well. They absorb the heat and then disperse it slowly, even after the system has shut down.



@ July 13, 2014 10:37 AM in Not Cool:

As you know, there is something way wrong if you cannot maintain 79 degrees in your condo. My wife keeps the A/C at 70 with no problems. Granted, we are in in slightly cooler climate (95 to 100) during a hot spell. Since the system is new, why are you troubleshooting it? I would set it at 72 tonight and show the tech tomorrow that you can barely maintain 79. If you put in a boiler and it would only heat the home to 60 on design day and you designed the the system for 70 I guarantee you would fix it. That's what being a professional is!




@ July 12, 2014 3:44 PM in Radiant cooling

Bob, I understand that you are in NH so your cooling needs are allot lighter than mine in VA. How much water does that system use? You must have the greenest lawn in town. Is there a reason why you don't just dump it back in the well? with the cooling needs in my area my well would run dry in a matter of days.
