General Outdoor Furnace Discussion / Re: Heat loss thru lines and hx
« on: October 19, 2011, 04:19:15 PM »
I went with the good stuff....just seemed like the right thing to do. That said the way I tell is a electronic thermo as the water leaves the boiler 177 in my case right now...hot water travels 70' to my crawl space thru Thermopex and the water is 176.2 and on the return side in the crawl I'm 172.4 heading back to the boiler...

Any harm in adding a second smaller pump on the return side? I put the main pump in my crawl right after my thermopex comes thru the foundation. I have the eletric and switch right there...I might give it a try and see what the results are....As I said I just added the second 16 x 21 HE and about 80 foot round trip to the one loop....I don't mind the added eletric and I like the idea of a back up....

Thanks for the reply RSI - 400 round trip. I just added the second HE in the attic (two weeks ago) and my domestic hot water does not seem as hot thru the plate exchanger. I would assume this is hot water flow issue? Maybe I was spoiled not having the additional HE and longer run in place last spring..I know the PL-36 is a beast I just wonder if I'm asking too much with all elbows and additional run to the second HE. What are the symptoms of an undersized pump?

Thanks I have six months to research....but the more I look into it - the more it seems it has legs....any info would be appreciated...

Plumbing / Question....
« on: October 19, 2011, 07:28:40 AM »
Wrapped up my install here are the particulars:
From OWB one zone 400' of 1" pipe driven by a B&G PL-36 pump to 30 Plate HX then to 1st Water to Air exchanger (both in the crawl space) and then to 2nd Water to air in the attic (up 10 feet or so one story rancher). I've tried to figure the head pressure but the only thing I figured was my head hurts from all the pressure....
Question:
Any quick and dirty way to tell if the one pump is enough? I have another PL-36 and or a NRF-22 I was thinking of putting on the return side not sure thoughts?
PS I understand that an open system has a tough time pushing water up...just not sure how tough. The system is working just want to hear what you guys think.
Thanks,
Jamie

Thanks for the replies...I see some of the challenges...What if we build a loop to pull the heat out but run the regular Air conditioning to deal with the humidity and latent air? I think the geo loop rad would have to be on the return side for this theory to work. I know this summer was a killer here in NJ and anything I can do to help - I'm willing this theory just seems to right to be wrong....Off to read some more...
Thanks keep the ideas flowing....

General Outdoor Furnace Discussion / Re: Adding water from inside house
« on: October 16, 2011, 05:53:30 AM »
I did when I plumed my plate heat exchanger after my "cold" water tank...Here is a picture. I've gotten pretty good a figuring out how long i need to keep the valve open to add water 
or ask one of the kids to watch the gauge. Works like a charm....

General Outdoor Furnace Discussion / It's getting cold outside - Air conditioning?
« on: October 16, 2011, 05:44:52 AM »
Now that I can keep my house 73 degrees all winter - I'm thinking of way to use the boiler infrastructure to cool the old homestead on those 100 degree July days. Anyone every tried a geo setup up to pump cold water thru their line set in the summer? In theory it's exactly what a conventional geothermal system would do pump and or circulate water in the ground. Here is the idea:
Take 600-1000 feet of 3/4 poly burry it 6-8 in a trench - t off my 1" supply from the boiler to the line set in the house - pump the water to air exchangers and back to the return side of the boiler - push the water thru the underground loop instead of the boiler. It's gotta take the heat out and cool the water right? I mean we all have the effort and $$$ into our line sets, exchangers and pumps this should work. I may need to mess with the pump and coil in the ground diameter/length by the theory seems sound to me. Any HVAC guys out there that can help size a geo coil?

I hear you and I may end up there - this one seems so damn easy....after all the other work done for the OWB. I know it's possible I'm kust not sure there is a thermostat the will let me contorll two heat sources....

I appreciate the help - I'll do my best to answer the questions asked in order:
RSI
The yellow lines are where I moved the respective wires.
Yoderheating
Moving the G to the W terminal only runs the fan when the first stage calls for heat (that is working correctly when I set the thermo up as single stage). You may be on to something taking the y out of play on stage one...had not thought of that..I was setting the thermo up as 2(H) 1(C)...
RSI
Yes the G terminal is empty. Is this wrong?
Maybe the easiest way to nail this is tell me how you have set up a single thermostat to control two heat sources, OWB primary and forced hot air (no heat pump) secondary. I just can not seem to find a thermo that is capable of 2 stage heat that will let you control each stage separately. I simply want the OWB as a primary heat source set to say 72 and my forced hot air propane system as a backup set at 67 in one thermo.
Thanks again for all the help - Installing this system was a ton of work and I just can't seem to get over this last hurdle...

Thanks for the reply... no G & W are not jumpered together and no heat pump in this system. The thermo can control one - If I set the thermo to heat pump with emergency backup my condenser runs - If anyone has one thermostat controlling and is configurable for a forces air and OWB please let me know what model I the wiring is pretty straight forward... If I moved the G to W2 is would make the OWB my second heat source with this thermostat....the more digging I do I feel like I'm going to be stuck with two thermos....

Electronics / Help GOING CRAZY!!! One thermostat to control two heat sources
« on: October 13, 2011, 08:08:39 AM »
Ok team – I have worn out the search function on this site and I think I have a fairly simple problem I’m trying to solve, help is appreciated; here it goes:
Looking to run one thermostat to control two heat sources:
System configuration:
- Outdoor boiler on/off on aqua stat in the unit & pump runs 24 x 7 (so no need to control anything out there)
- Inside forced hot air system with water to air heat exchanger
The issue; I’ve tried a number of professional Honeywell thermostats ( I have the 7600 right now) to control two heat sources. The heat pump with emergency backup is out as I have no heat pump and I don’t want my condenser running while I’m trying to heat. So I went to the two stage heat, it works but I can’t configure the settings, I can’t change the temperatures. I called Honeywell to verify my connections they said everything was correct and the only way to use any Honeywell in this configuration is to use the non configurable two stage heat. I’ve attached a picture of what I have done, the yellow lines are how I’m setup in the 2 heat stage mode and it works but the furnace kicks on after about five min of the fan just running so it defats the purpose of running the OWB. I realize I can go the two thermo route – just feel like we are smarter than this problem and I just have the wrong thermo – any thoughts? Trying to stay away from adding switches (I can think of a few ways to do that) and or additionally relays, trying to make this as straight forward for the wife and kids while I’m away on business. HELP!!! 
Thanks,
Jamie

Plumbing / Re: Heating my domestic water
« on: April 18, 2011, 04:45:00 PM »
I agree on the mixing valves..too temperamental. I went with a thirty plate mounted in my crawl after my tank. Not quite ready to fire it up for the first time just yet - I'll keep you posted on how I make out. Running out of how water - two teenage girls and two Jacuzzi tubs - was the reason I went with a big plate after the tank - fire in the boiler there will be hot water - and all the plumbing is down below I don't have a ton of room in my new my water heater...
