I'm thinking about hooking my new 6048 directly instead of through my HX what do I need to do to make this happend and will this effect my propane boiler if it were to kick on if I run my line temp below setting..
-
You're central is a open system, you're LP boiler is a closed system, bad things can happen if you don't keep you're closed system pressurized. Get the proper HX and do it right the first time, it will save a lot of headaches in the future.
-
For the somewhat small price of a FPHX and another pump, you will save the big dollars of not messing up both boilers.
-
LittleJohn and mlappin are spot on, use the plate exchanger. Is your gas boiler a floor mount or wall hung?
-
My wood boiler is above the grade equal to the middle of my first n second floor so I have 9psi of pressure at my oil burner that's why I went that way n my house system I put anti-freeze cryo teck in the system 18 yrs ago n water u would of drank it if you didmt know better,clean,what r the draw backs of direct plumb,my system has the thermostat valve that shuts under 150* plus I installed valves to isolate the two?
-
If you haveany portion of the radiant system above the top of your OWB, you can cause vapor lock and water will not flow.
Gylcol has to be checked at least once a year,, just like water treatment to make sure it has not spoiled and turned acidic
-
Ok I'm currently running a 70 plate HX on my existing OWB but I see everybody talking about better efficiency hooking directly into the system so I was courious I want it to run the best it can..
Slim my boiler is a munchkin 199 floor not wall hung
-
My circulating pump runs constant to upstairs coil this for me is the. Best way so when house calls for heat upstairs the blower doesn't have to wait for boiler to heat the coil it takes time sometime that zone will not run all day due to downstairs heat rising upstairs everyone's set up is different mine works flawless it will. Vapor lock if pump starts n stop that's why the little 007 runs constant for all that water to cool off in attic could freeze if not run

If your not getting enough heat then it's one of two things, pump isn't moving enough fluid from the OWB or you need a larger plate exchanger. Running a 70 should be plenty unless you're heating a LOT of area or have more teenagers coming and going and you can't close doors fast enough.

Def dont do a direct hook up with a open outdoor boiler.. Being that said you will be exposing all of your plumbing to the atmosphere.. I have a direct hook up because my wood boiler is a closed system....Stick with the heat exchanger..
-
Ok Thanks everybody finally put my mind at ease I will continue hooking it up the way it was originally I think it will work just fine today I will be swapping out the boilers out with the ACME in with the central boiler let's hope everything goes smooth.. Lol
-
You guys sound like I dreamed this up Sunshine tree my dealer look over my hook up EVERYONES IS DIFFERENT with the elevation of my wood boiler said perfect for direct! Do t u think he would of like
d to sell me the HX ? What u really need to talk about is exposing to atmosphere did u add corrosion additive and TESTING THE QUALITY OF WATER!!!!! put a piece of steel wool in Masson jar full to top no air n see what it looks like in a day or two! Direct is fine depends on your setup! By the way I did ALL OF THE WORK PLUMBING THE WHOLE JOB NOT JUST SITTING HERE TALKING about what someone did for me!

Of course it depends on your setup, go out and buy a new closed boiler for your house, then tell them your going to hook it up to an open system and not pressurize it, let us know how well the maker of the pressurized boiler honors the warranty in a few years.
-
That's why I say everyone setup is different,my old oil burner boiler in house,that's clean.like I said earler my outside boiler is above grade I have a guage on the inlet side reads 9 psi so there more than that at the oil burner WE ARE ALL ON HERE TO HELP EACH OTHER NOT TO PUT THEM DOWN IF ITS NOT WHAT THEY HAVE LETS JUST HELP EACH,IF THERES A REASONS WHY NOT TO OR HOW TO DO SOMETHING SAY IT,BUT IF ITS NOT GOOD FOR YOU DOESNT ALWAYS MEAN IT NOT GOOD FOR SOMEONE ELSE THANKS. GREAT PEOPLE WITH LOTS OF SMARTS HERE THANKS

So I left it the way it was after hooking up the new boiler I watched my temps OWB set at 185 incoming to HX 184 back to boiler 165 now the other side coming out of the HX to my zones 160-165 is this reasonable temp after HX to feed my zones or should I be getting a higher temp?
-
160-165 on secondary side of HX, should be good, but I also have no idea what your application is.
HOPE THIS HELPS:
If its In-Slab, YOU ARE WAY TOO HOT, need to mix down to at least 120 or cooler
If its Under-Subfloor, You may be a bit hot but in the realm of possibility
If its Radiators or other Water to Air HX, I am not 100% sure but you may be a little on the cool side (I have never installed so I do not know normal operating temps)
If its SNOW MELT, Still a bit hot for that, but GOOD LUCK and I hope you have a HUGE wood pile or small snow falls
If its heating your DHW, It will work and you will need tempering valve!!

Little John I running underfloor radiant with mixing valves and baseboard as backup and primary heat for second floor I know baseboards should run at 180 and underfloor at 140-160 my only concern was with the HX wasn't sure if 20 deg diff was normal on the house side if that's ok I won't go any further just want to get the max btu's out of the HX.. Thanks all for ur help
-
A delta of 20 across you HX does sound a bit high...
You say you have a mixing valve on the secondary side (not OWB side); is there a chance that is what is limiting the max temp on that side of the HX?
-
The mixing valve is for my radiant loops only... What should my drop be across the HX
-
The temp I'm reading is coming out of the HX off my primary loop before it gets to my baseboard t's . I have a 008 taco pump before the HX on return side my concern was that the 008 was not enough flow allowing the low temp?
-
I have a 40 plate ex and that's the same temp I have on the 2nd side ! And iam max out . I run my 6048 at 195 I like to run it hot to keep the oxygen out of the water.
-
Fire boss I'm right there my self across the HX I was getting whacked out readings at first there must hv been a lot of air in system still giving wrong temp readings she's good now running perfect and the 6048 is incredible my house is difficult to heat high ceilings with open ares to 2nd floor sitting on a hilltop with wind constantly blowing during this time of year and it is a comfy 74 deg with 15 hr burn time I can't ask for any better..
