Yes i do have 3/4 off the boile to1 inch underground then 3/4 in house

Your flow is killed........ 

You need something like a 25-10 pump to handle that, you barely have any flow the way it is...

[Scott7m]

It's hurting you in more ways than just that as well, I'd be afraid to say what your return temp back to the stove would be if it's already considerably cooler out of the coil, of course it's probably robbing some heat from the supply line as it goes back out

You would only want the water difference from in and out of the coil to be around 20 degrees max

What do u recomend

[RSI]

Willie yes the return line off the exchanger is considerably cooler when the furnace is running. Its a 007 taco pump which i think is 20 gpm. Im about 80 foot total from boiler to exhanger.

Your probably down to 1-3 gallons per minute if you have many elbows.  007 won't do 20gpm I don't think if it had a 1 ft run with no restrictions

A 007 can do 20 gpm if you have a few feet of 2" pipe. (Something that will never happen on an OWB)
I would guess the same 1-3 gpm range that it is running.

[Scott7m]

With you having that distance and some 3/4" piping involved I'd reccomend a  GPD25-10SFC, would run you about $175 to your door.   

If you wanted to try to save some change you might find a good 011 or something like that online, but the pump I was pricing you is a 3 speed, you can kind of adjust it to suit yourself.

[Scott7m]

I have no used pumps at this time, RSI may have a used one that would work for you

Ok ill let you know. I really appreciate all the info, its been a great help as i scratch my head. I love figuring out problems but sometimes i get discouraged. Thanks again

The pump probably isn't the only issue, but it won't be possible to correct anything else as long as that's messed up and severly under sized

[csmart94]

A 0011 taco should be big enough?

[Scott7m]

I think the 011 will do about 31' of head, so yea I'd think so

[csmart94]

Ok well i bought my pump from menards so i thought they might take it back and ill get the 0011 they have them in stock

[csmart94]

Pumped changed to the 0011, im guessing i still need to change my underground pipe cause i am still useing more wood than i think i should.

[Scott7m]

Yup, like I said, the pump had to be fixed to be able to start fixing other issues.  There is numerous line choices for you to choose from.

[csmart94]

what do you recomend, if i buy something, it might need to lay ontop of ground untill spring. Is foam filled better than the wrapped?
