What size of wire needs to be run from the house to the OWB?? Solid cooper or not? At times with my job when we wire up something new I can get the left over that we have, looking to save on having to purchase to save on install.

im not sure what you need for wire  but if you can find out what supply wire you need for the furnace (amp rating) the dealer should be able to tell you. you can look up on the net if you need to go heavier for the distnace you will travel.

In my area I can use 14/2 and I was in the poor house so that is all a ran in a plastic pipe, but if you have a long run add a extra wire

[Scott7m]

I always run 14 gauge, that's what your supposed to run with a 15amp circuit

[willieG]

as your run gets longer the resistance in the wire can cause heating and loss of power to your appliance. taht is why on a long extension cord something that draws a lot of power like a skill say for instance can create the cord to get hot and the saw may not have the maximum power it would have if plugged in a shorter cord. you can use a larger wire for a run that is say over 100 feet or so and not break any laws..you can use a larger wire than the breaker is rated at but you can not use a larger breaker than the wire is rated.

Unless you are have an outlet on the stove and plan to use it for something else then 14ga is fine. Most stoves don't use more than a couple amps.

i agreew ith RSI, most folks will be fine with 14/2. my run was 250 feet so i used 12/3 and a double pole 15 amp breaker (my stove is in an outbuilding) i run the OWB off one side and put a plug and some lights in the shed off the other pole

i think i may consider upping wire size after 150 feet just for "good luck"

Thanks all for your input. 75 ft will probably be the furthest my stove is going to set from the house. Got all different kinds of wire to choose from with different variances of pairs so probably go with at least 14/3. Again thanks to all.

12-2 with a ground and you will not have any problems.

[fireboss]

I went went with 12/2  also

[swede]

I ran 12/3 but didn't use the third wire and wired the pump to run 24/7.  The wire is there if I want to change it to an on demand setup.

If you run a 3 conductor, you could make a few changes on you OWB lighting circuit and tie it into a switch inside your, then you will be able to turn the light on before you go out in the dark.  As a rule of thumb, you would normally upsize you wire for every 100 feet.  If you think you may want to add additional lights or possible a receptacle, install the wiring for it now, a couple of years later you don't want to be kicking yourself for not doing it.

I would run 14/2.  If you want run two of them.  That will give you the option for extra things and still keep your furnace on its own circuit.

I had the underground rated 12/2 left from another job and I pulled it thru the 4" ABS with the PEX.  I'm wouldn't doubt that somehow it is a code violation  .

I come out of the 4" ABS with flex conduit to the OWB.  Once in the house I go to normal 12/2, but I have both circulators on the same 20A breaker.

I also ran 12/2 and put it on its own breaker so i can get power to it with generator easier if i ever need to
