@ October 9, 2013 1:39 AM in Webster Sylphon steam trapunder the floor returns. All except a few are in the ceiling or disappear into the land of Oz.
@ October 8, 2013 6:50 PM in Webster Sylphon steam trapthat these traps are blown?
All the photos were taken soon after the boiler started steaming. The trap in the first picture was painted white, so I believe the readings are accurate. The traps in the two that follow are not painted and I believe the emissivity of the chrome finish is distorting the temperature readings. However, the outlet pipe below the trap is reading the same temperature as the inlet.
This house had 20 radiators and they all tested the same, i.e. trap outlet temperatures the same as trap inlet temperatures.
If all these traps are bad, how is the system able to operate? Most of the radiators work fine.
@ October 6, 2013 6:21 PM in Webster Sylphon steam trapSo you recommend replacing the seat as well? Kinda' makes sense.
Do you find that your infrared camera works well to test these traps? Do they clearly show a temperature differential between the trap inlet and outlet?
@ October 5, 2013 1:37 PM in Webster Sylphon steam trapOne of my customers was having problems with their 2-pipe steam radiators and I took apart one of the Webster traps. The element is attached to the cap and I'm wondering if they can be separated??? Also, who makes a replacement?
@ October 4, 2013 1:14 PM in draining/filling when radiators have TRVIf you remove the thermostatic head off the valve, it will allow the stem to extend out, opening the valve.
There is usually an allan setscrew that secures the head. Others are removed by just pulling them off.
@ October 4, 2013 1:46 AM in primary/secondaryis to wire it off the boiler if it has a pump relay.
If not, create you're own pump relay off the end switches as you say.
@ October 3, 2013 4:01 PM in Great ArticleAnother reason for heat loss calculations on all your jobs and not add anything to that number for an indirect.
I see Alpine boilers come up quite often on The Wall, but have no experience with them. Are they good?
I subscribed to the US Boiler Report here:
@ September 19, 2013 9:32 PM in high ceiling ... BB - Rads matter?Baseboard is a cheap solution for heating a room. The problem is, there is often not enough wall length to install enough BB to heat the room properly. And very often, whoever installs the BB doesn't do the math and installs less BB than required to heat the room properly.
Radiators look much better and are more expensive than BB. Often, homeowners will choose the cheaper solution.
As far as higher ceilings, a room with a 13 foot ceiling has more volume than the same room with a 7 foot ceiling. If there is an outside wall, there is more infiltration and the heating needs will be greater. Longer lengths of BB or a larger radiator.
Choose a good heating professional to make the calculations you need to size your heat emitter, whether it be BB or a radiator.

@ September 9, 2013 9:16 PM in stainless vs stone lined on long island(Mr O' Brien)How would a Viessmann indirect stand up to these hard water conditions.Yes, they are stainless steel, less the anode rod, but those Germans, you know: they figure these things out.
@ September 5, 2013 9:09 PM in Solid vs Engineered Hardwood for OverpourI would do everything possible to get away from engineered flooring. It doesn't look anywhere like the real thing and like you said, it's bouncy which may be easy on the back, but it sure doesn't evoke solid quality.
Warmboard, Climate Panel, Raupanel, Quik Trak, Thermalboard..........whatever it takes.
@ September 5, 2013 11:22 AM in Which T&P Valve?Here in California, you have to use a relief valves rated higher than the input rating of the boiler.
Look at this chart (over 200,000 BTU) for correct sizing:
As far as the higher price, it's probably related to their insurance costs and not the manufacturing costs.

Where do you see it?
@ August 6, 2013 9:30 PM in MikvahThanks everyone for turning me on to Moses; what a guy! He emailed me and then called me to offer his magnificent morsels on mikvahs. With a name like Moses, I trust him.
@ July 31, 2013 7:20 PM in MikvahI've been asked to re-pipe a mikvah. A mikvah is a heated pool used in Jewish cleansing ceremonies.
The existing mikvah uses a pool heater in a separate room next to the mikvah. It was explained to me by the rabbi that this mikvah was not installed properly; that the water in the mikvah must stay in the mikva and not leave the room to go through the heater, pump and filter.
They have ordered a heat exchanger (shell & tube?) that will sit in the mikvah and want a wall-mounted boiler to serve it. The existing Raypak pool heater will not heat to 180F. Can any of you make a boiler suggestion? An "on-demand" heater might work, but I want something beefier (non-condensing) that's meant to operate at higher temperatures. The existing pool heater has an input rating of 181,000 BTU's.
Also, I'd like to pipe it in copper, but don't know if copper is resistant to chlorine.
@ July 28, 2013 3:36 PM in Precharge Expansion tank: old school non-bladderto know how it's piped into the system, i.e. on the vertical supply coming out of the boiler?
Expansion tanks and their effect on the heating system can be very complex; more than my little brain can comprehend. I have replaced or recharged many expansion tanks on systems that over-pressurize, only to have the symptoms repeat. Some have bad fill valves, some have pin holes in the indirect heat exchanger, but the majority seem to just not be able to get along with the expansion tank even though it is properly sized and charged.
@ July 26, 2013 9:02 PM in floor made of framing planks turned on edge: radiant heat below and finish above?They used to have output charts for their Thinfin C as a function of the R-value of the floor, but I can no longer find them on their website.
Heatloss on new houses here in the Bay Area typically come in at 17-20 BTU's/ square foot. I want to see if theses accelerator plates can approach that with the kind of floor that Simon has.
@ July 25, 2013 11:29 AM in diverter teeYes, I would use a 20 degree delta tee, figure out the BTU's of each unit and size the mains accordingly. It will probably come out to something less than 1-1/4 bacause you're dividing the load.
If you have enough money in the job, I would pipe it with a 2-pipe, reverse return system. A diverter tee system is notoriously difficult to purge.
@ July 25, 2013 1:31 AM in diverter teeAre each of the apartments going to have their own thermostat?
@ July 23, 2013 1:28 PM in I was all set to order my boiler...They have been out West here for most of my 33 years in the trade. Their products are top shelf. In my opinion, you would not be making a mistake to install one in your house.
