I have to pose this question just one more time before I hook up my system.  Is this going to work?  Someone had mentioned that it will "starve my system" .    What does that mean.  I got a local OWB guy to look at it and he just wasn't that familiar with the indoor boiler system tying into the outdoor...Just looking for any observations please.  You can see I'm tying the OWB in with the 80 plate heat exchanger right where the water enters the return on the Indoor system. 

I guess my goal was that since the indoor boiler heats everything (hot water, radiant floors, furnace exchangers) I could use the OWB in the winter and when it's shut down in the summer the IWB takes over to just heat the hot water.   Any and all suggestions again are welcome.

I don't see why it won't work, I'm assuming that your wall hung boiler has it's own circ that comes on with a call for heat? I would have preferred that your return did not only go to the wall hung as now you will be sending very hot water through the wall hung and there really is no need to do that, A true primary secondary would have allowed you to take either system out of the loop and still be able to heat with the other system!

I think I see what you are saying.  Can this be remedied easily to make it a true primary secondary system should I have problems? 

The biggest problem I am seeing is that if I let the OWB go out, the indoor system will be heating the outdoors water throughout the plate exchanger. No?

If I am putting hot water into the return on the indoor exchanger won't that just keep it from firing up?

A little off topic, but I do like you're basement, ours is semi unfinished but all the floors are sloped to one of three floor drains. Doesn't get wet very often but I still place everything on patio blocks. Also have both washers and dryer in the basement. I don't plan on repairing anymore wood floors because of water damage from a small leak that goes unnoticed for awhile.

I would have tied the supply and return on the wall hung together and put a circ on the main loop then bring that line back to the heat exchanger, I just tried to post a drawing but it tells me the download file is full, perhaps somebody could fix that!

Wow, that sounds like a brilliant solution that would be relatively easy to accomplish!

In reality, that is the way we should be doing them all but it is more expensive, Parts and Labor

I believe that is how you did mine isn't it slim? A primary/secondary loope...

[slimjim]

I think so Randy but that was a lot of boilers ago, My wife just got home from 5 days gone to Mass, I'm having trouble remembering her name and you want me to remember your install?

[randy_1]

Your wife is Lisa right? Lol

Ok, OWB is fired up as of yesterday.  Cranked it up to 170 and was working beautifully until my plumber told me I can't pump water over 140 into my floors. So I set stove back down to 140 and it went out in the middle of the night.   How do I keep it at 140*f?  Smaller fire? 

[slimjim]

HE NEEDS TO PUT IN A MIXING VALVE!!!!!!

[tulenutn2o]

What slim jim said. Higher temps and concrete, not  a good "mix".

[cartod]

How do you put fresh water into a closed system with a mixer valve? .....where does new water go ?

Also how hot of water can I pump into the concrete and what temp is ideal?

Am I going to be able to maintain the fire at 140* without it going out? 

Thank you folks.

hey pal, im a fairly new outdoor furnace guy as well,3 yrs,you need to get someone asap who can hook up your furnace the right way,if your heat guy didn't know u needed a mixn valve or that you should be running your furnace at 180 degrees,you need a knew guy,i went thru a view growing pains as well,and I am still playing with things making it run better each yr,my advice ,fly slim and a few of his buddies to your house (kiddn) but really get someone who hooked up a few already and it will save you a ton of grief...
