What kind of circ are you using?

A UPS 15-58 on low speed draws 60 watts, and I thought that was pretty good, but you can't put 15 zones on it.

Thanks
Tom

Siggys Seminar

Went to Edison NJ for John Siegenthalers seminar yesterday. A very good day spent in the company of some very sharp people.

Johns thoughts on electricity consumption made it clear that a hydro air system is the worst way to distribute heat energy - at least as far a BTU per watt comparison goes.

It hit me in traffic on the way home that the best BTU per Watt ratio must be steam - fire the burner and let the vents do the rest.

Score another one for the Dead Men.

Thanks for a great day John!

Hmmm. My calculator is going to catch fire on this one. I am going to have to look at that...

Nice to see you again as well as Anthony and Scott. Sorry I had to leave a couple of hours early but I was having a real tough time due to my meds. They tend to give me extreme anxiety when I have to sit still for abnormally long periods of time. I would assume that some day my body will adapt but for now I have to keep moving. Up until last week I have been working from my home with no traveling due to the heart problem. If I started to get "bugged out" I would just drop everything and go for a brief brisk walk and all would be fine. Sitting in the front row at John's seminar I had a difficult time trying to get up and leave for a few minutes to deal with this without disrupting the meeting. I found the 3 to 3-1/2 hour stints without a break to be more than my anxiety could handle. Lots of good info though aside from the "no break" thing.

Good to see you

as well Glen.

I trust you have spoken to your Doctor about the side effects, they may be able to make adjustmants if they know about the problems.

Old school boiler guys tend to "suck it up" - not good.

The form says Patient Complaints, your job is to fill it up.

Get To Work ;-)

Hi TGO,

Steam may be the best in BTU per watt but not the best as far as total energy in vs. energy out. Forced air hydronic is only slightly worse than a forced air furnace on electric usage, especially if the circ. is properly sized and efficient (waiting on the Grundfos Alpha).

It's the forced air part that uses the most electricity.

The distribution on my 15 zone hydronic system uses less than 25 watts when all zones are calling including the circ.

Hi TGO,

I am using a Laing D4 circ. It really takes some creative piping to put 15 zones on that small of a circ. Basically I am running 3 parallel loops from one pump with 5 zones in series on each loop. The zone valves are 3 way so the un-called zones are bypassed allowing hot water to continue to the other zones. The bypasses are balanced so they have the same flow as thru thier associated zone. Each zone has a rather small load and with all zones in a particular loop on, the delta T is about 25 degrees. The emitters were sized for 1gpm and 5 degree average delta T.

Piping 15 zones on a Grundfos UPS15-58 on low would be a piece of cake.
