@ June 21, 2013 4:36 PM in humidity and temperature recorderSearching the Internet and found something called a HOBO. has anyone used one?
@ June 21, 2013 2:32 PM in humidity and temperature recorderLooking for the latest in temperature and humidity recorders for HVAc monitoring. What's oout there? What do you recommend?
@ May 21, 2013 2:56 PM in Reverse IndirectHot Rod. I found a brand new distributer for Thermomax right down on VA. not far from us. The Joyce Agency has just taken on this product line. Thanks for your help.
@ May 21, 2013 8:23 AM in Reverse IndirectZ man. the thought had crossed my mind. I'm having trouble finding distributers for Thermoax or Ergomax. Did they go out of business?
@ May 20, 2013 12:13 PM in Reverse IndirectI understand what you mean by external. HX. What I'm picturing is like the Thermomax. I need a buffer tank and an indirect but the capacity on the indirect is not very high. Just for hand washing and cleaning crew usage. No showers. I'd love to put the buffer tank and Domestic hot water on a single footprint,
@ May 20, 2013 9:15 AM in Reverse IndirectI remember thinking once that a reverse indirect would make a good buffer tank in the right situation. That was a long time ago, but I think I find myself in the right situation. What brands of reverse indirects are out there these days? Does anyone use these?
@ May 16, 2013 8:45 AM in zone valve questionI'll remember that for next time. I've already bought a Belimo with a cv of 57 for a 2" zone valve. Since my gpm is 40 I'm good with that.
@ May 15, 2013 10:03 PM in zone valve questionOf using the large Wilo for the 15 and 40 and using a smaller circ for the single digit zones. I'll look at the pump curves tomorrow.
@ May 15, 2013 7:08 PM in zone valve question??????????
@ May 15, 2013 1:24 PM in zone valve questionWhat are CCV's? My gpm's are; 40, 15, 8, 8, 5, and 5.
@ May 15, 2013 1:07 PM in zone valve questionRanging from 1" to 2 " Why break it up into multiple circs. One oughta work. Or am I missing something? BTW I found Belimo had the 2" zone valve I needed. Thatnks for the suggestions.
@ May 11, 2013 10:53 PM in zone valve questionPlanning on using a Wilo Stratos 2x3 x35 on six zones. the largest needing 35 to 40 gpm.
@ May 10, 2013 2:17 PM in zone valve questionI used two 1-1/4 zone valves and teed them together downstream?
@ May 10, 2013 8:24 AM in zone valve questionWe are installing a large (for us) boiler system of 1.2 million btu's. We have 6 zones of varying sizes. I usually use Caleffi Zone valves but their largest zone valve is 1-1/4" with a cv of 7.5. My biggest zone is 2." Should I reduce down to the zone valve or find another manufacturer that makes 2" zone valves? What problems could I be facing?
@ March 12, 2013 2:08 PM in evac tube drainback system5 years back when I installed my solar hot water you could not install a drain back system when using ecauated tubes. The evacuated tubes could be damaged if they sat out in the sun without the heat being taken away from them. Recently someone told me they have new tubes that can be used with drain back solar systems. Hvae any of you used them or know of them? Do you have any links that would help me find them? Thank you for any help you can give me.
@ March 7, 2013 9:08 AM in Radiant Tables in GreenhousesI looked at a large commercial greenhouse a few weeks ago that had radiant floors everywhere that most of the plants would sit on to keep their roots warm. But they also ran hot water through pipes where hanging planters hung and used them for secondary heat when the radiant floor wasnt enough. I know most of the park greenhouses where I work, have tables where the plants sit. Less bending over I'm guessing. I've been thinking. What if we made these tables radiant benches. I could use warmboard or climate panel. I could also run tubing on the table top and encase it in mortar or some otherproduct of thermal mass. Maybe I could make a tabletop out of copper tubes although that seems a little pricey. Have any of you seen such things or am I on my own in the creative proccess? Let me know what you think.
@ March 6, 2013 4:11 PM in Snow Melt Water TempsI've been running at 90 and was afraid that was too high. I have it set down to 80 as an experiment. I'll let you know how it flys.
@ March 6, 2013 8:56 AM in Snow Melt Water TempsI have a small snowmelt system for our sidewalk out fron. What sort of water temps should I be seeing across the system, supply and return when it is operating during a snowstorm???
@ February 2, 2013 4:16 AM in PredictionsWants Baltimore. My brain says SF. Lots of individual talent in the pool for SF. if they play well as a team they should win. Baltimore plays well as a team already, but can they overcome the talent gap?
@ February 2, 2013 4:12 AM in Carrier VVT systemI have been asked to upgrade and modify a 20 ton VVT system that has never worked well. One of the fist things I want to do is replace the bypass dampers used to control the static pressure with a variable Frequency drive to control the speed in response to the static pressure. I need leads to manufacturers and info on how it's done. thanks.
@ January 4, 2013 3:21 PM in wifi thermostatsWhat be dat? Where can I get one? Lead me to an understanding Obiwan Kenobi.
@ January 4, 2013 3:04 PM in wifi thermostatsI've been installing the new Honeywell 8000 wifi tstat. It's been working well on a few jobs, but.... I decided to put 5 in a small commercial building so I could monitor the temps and they could not connect with the wifi, and disrupted the customers service. Their Wifi wouldnt work until I disabled the eifi feature. I need to call Honeywell and see what could be up but havent had the time yet.
