@ December 6, 2013 3:29 PM in finished basement= trapped vent and cold radiator?If valve is frozen closed radiator will be cold. Handle can turn but not pull spindle.
@ November 29, 2013 7:33 PM in Gas-Fired Steam BoilersDid you forget this brand? I bought them cheaply in the seventies.
@ November 29, 2013 4:06 PM in one pipe steamAir vent valve is the only one recommended for one pipe. You're not supposed to modulate the intake on a one pipe. That angle valve is strictly for full open or completely closed. There's thermostatic vent valves with an integrated vacuum break.
@ November 26, 2013 8:16 PM in Smith becomes WestcastWasn't HB Smith the original steam heating company?
@ November 20, 2013 3:46 PM in conversion from one pipe steam to hot water>> Since almost all of these systems have separate risers for first and second floor radiators, this would avoid making any changes in the units themselves.
@ November 20, 2013 3:32 PM in Dielectric fittings in Hydronics copper to blackWell I'm an old engineer.The question is how long will HW heating system not leak when ferrous and cuprous are joined? Bronze & CI may be okay but copper soldered to steel?
@ November 18, 2013 1:59 AM in BURNHAM BASE- RAY & One-Pipe Steam SystemCondensate will not run up.I hope that those baserays are above the main.
@ November 18, 2013 1:55 AM in Oil-Filled RadiatorBuy a 400 watt oil filled heater and leave it on longer. The NewAir AH-400 Energy Efficient 400 Watt Oil Filled Personal Space Heater has a temperature control. You can also hang drapes along the outside wall to feel warmer.
@ November 17, 2013 12:29 PM in steam pipes on interior wallsIt's up to architect to provide chases for services. When I serviced multi-residential I could easily tell when architect was in sync with heating and when designer and installer had to work around.
When there's a redo it is cheaper to just drop pipes in interior.
@ November 17, 2013 12:19 PM in System LayoutI'd price of controlled circulators versus zone valves. And then I'd do some heavy thinking arguing with myself. I think that modern boilers are best with constant flow so ideally one controls the airside capacity of each terminal. I don't understand why people on this site are such fans of using heating boiler for DHW.
@ November 16, 2013 7:41 PM in How to control radiators in a 1 pipe hot water systemKeep in mind that you can increase output of a radiator with appropriate enclosure.
If you haven't done so already, get ahold of Greening Steam.
@ November 15, 2013 4:13 PM in Dielectric fittings in Hydronics copper to blackYou have to connect some way so why not by the book? While on the subject why not add a little water treatment?
@ November 15, 2013 1:50 PM in How to control radiators in a 1 pipe hot water systemGreening Steam has a section on this subject. It applies to hot water as well as steam.
If you use louvres you can adjust each room whenever you like.
@ November 15, 2013 1:43 PM in Edwards Valance HeatingComplaints that heating mode could smudge ceiling. Condensate draining can be problematic with any system. Just ask any AC tech. Virtually every valance I've seen used hot water but I think steam is better because I don't like hot water up there.
The reason why it's not more common has to do with distributing chilled water to every room. Insulating pipes is expensive and must be done correctly.
@ November 15, 2013 1:08 PM in 11 Buildings 1 boilerIs return line clear or filled with water? Does water pour out of radiator? Suppose return for that building is not flowing.
@ November 13, 2013 5:04 PM in Is steam still a viable heating technology for new installs?Modern construction is tighter and better insulated. So pipes can be smaller than olden days. Overhead distribution also allows smaller risers except for main one to attic. I'd use one pipe to save money and modulate with dampers or louvers on terminals. Those would be finned pipe. Also saves money. I'd seal the system and mechanically evacuate so that I could eliminate vents. Another economy. I suspect that such a steam system could be less expensive in a new building than ductwork. Only thing working against this is that furnaces can be cheaper than boilers.
@ November 12, 2013 5:13 PM in Is steam still a viable heating technology for new installs?Steam heat may be out of fashion but it can be less expensive than HW to install in large buildings. And if done wisely it can be less expensive to maintain. Pumps and motors don't last forever.
@ November 12, 2013 5:04 PM in Galvanized underground condensate return pipingMake sure it isn't galvanized on inside of pipe unless you want ZnOH inside your boiler.
@ November 11, 2013 1:08 AM in hydro therm boiler issueThis thread reminds me of Adams burners from fifty years ago. To light the pilot you turned on a little valve to manually light a little "pilot pilot." The flame from this manually lit pilot travelled down a tube to light the main pilot. Then you'd turn off the manually lit pilot and the main pilot would stay on.
I've long wondered why we use electric devices to hold gas valves open. Wouldn't a thermo-mechanical device be simpler?
@ November 10, 2013 5:24 PM in BURNHAM BASE- RAY & One-Pipe Steam SystemLAOSH illustrates this. Slope the baseboard so it drains away from main pipe and then run a little return to some where lower down. I've seen similar approaches for unit heaters.
@ November 9, 2013 5:37 PM in converting gravity system to pump forstUse transitions from new small pipes to old large. Supposed to be better than simple bushings. Biggest issue is expansion tank. If it's open you may want to consider closed.
@ November 5, 2013 11:31 AM in Twin Boilers - One Pipe Steam SystemWhy not stage according to outside temperature? One pipe works best when it doesn't cycle too often.
