Home Made / what size draft fan needed?

« on: January 04, 2015, 07:45:59 AM »

Couple questions about draft fans.  Well the new OWB seems to have trouble getting back up to temp.  Maybe cause the air temp is in the 50s right now and I dont really have a good bed of coals yet?    If I decide to put on a draft fan, what size would I need?  My fire box is a 1/2 500 gallon propane tank shortened another foot. 
Does the draft fan have a damper door on them?  the temp is supposed to drop from the 50s today to the teens tonight.  I will see how it works when I get a good bed of coals.  But still need some info on the draft fans because I may have to go that route.

Thanks Newmod

Electronics / Re: 20 amp breaker keeps tripping

« on: January 03, 2015, 07:49:35 AM »

Ok guys, we figured it out.  The pump and solenoid is only drawing 1.8 amps. No problem.  Pulled the wired off the solenoid. Still tripped.  Pulled the solenoid wire out of the aquastat. Didnt trip.  Installed a temporary hot wire from aquastat. Everything works fine.  IT WAS A BAD WIRE. UGH.  .   Cheap and simple fix.  Just glad I dont have to wait a week to get it in the mail.  The wife is happy now..   thanks guys

Ya. I am gonna just wire nut everything together in the morning.  And then pinpoint it that way.  Gonna disconnect 1 at a time to find the problem.  That pump only draws about 5 amps. So it shouldn't  be that unless jammed or a short somewhere.  I will let you all know what I find in the morning.  Hope it is a simple fix.  It's gonna get real cold here and the freestanding  stove ain't gonna cut it.

When the switch is off everything is fine and breaker doesn't trip. Once the switch is flipped on it trips in a couple seconds

The pump and aqua state are ran thru a normal switch next to aquastat.  With the breaker off I have the switch off.  Unplugged the solonoid. Switched on the switch and the breaker tripped in a couple seconds.  Maybe the pump locked up for some reason.  I have no idea.  It is such a simple system, I shouldn't have this problem.  Never had any problems with previous build.  Ugh.

Electronics / 20 amp breaker keeps tripping

« on: January 02, 2015, 06:24:22 PM »

I just hooked up and and started the first burn in my new owb.  It is a homemade (2nd one I have built)  taco 009 pump. Ranco aquatat. And normal solenoid for draft door.   Aquastat set at 190 and 160.  Was running fine, up to about 120 deg.  And the 20 amp breaker started tripping.  Only thing on the circuit is the owb with 12-2 wire.  Switched breaker and keeps tripping.  Ran good for about 4 hours without problem now breaker trips in about 3 seconds.  ANY IDEAS OUT THERE ??.I am gonna take apart the pump totomorrow and see if it has locked up or something.  Also have my buddy (electricalengineer) coming over in the morning.

Plumbing / Re: plate exchanger on WH question

« on: December 24, 2014, 05:37:41 PM »

I prefer to leave the blow-off valve unaltered from the factory.  The hot outlet at the top of the water heater is fine to tee into for your plate exchanger. 

I'm curious, are you using a circulator to move the domestic water through the exchanger or relying on thermosiphon?  Also, have you considered simply using the plate exchanger for on-demand hot water and shutting down the water heater as well as valving it so it's not open to the water system while you're using the plate exchanger?

I just rely on thermosiphon .  The 2 OWB I have owned before I have done the same way without problems.  Thanks

Plumbing / plate exchanger on WH question

« on: December 24, 2014, 01:15:16 PM »

Should the top of the hx loop tee into the blow off vlave on the side or should I tee it into the hot coming into the top of the water heater?  I only ask because my precious hookups were into the blow off valve that was mounted on the top of WH.  My relief comes out of the side of the WH.

I have had one for the past 3 years and the only problem I had with it was the wheel broke.  Other than that, it works great.  As the other poster said, you have to hold it as you sharpen.  It does work great though for the cost.  If this one broke I would buy another !!!

« on: November 02, 2014, 11:52:22 AM »

The last woodburner i built took probably around 2 hours that i remember.  It felt like forever.   I thought i was having a draft problem because i thought it was taking too long.  But once up to temp there has not been 1 problem at all.  I am finishing up my second build now, and someone contacted me about building them one.  UGH.

Home Made / problems using 500 gal. propane tank

« on: November 02, 2014, 08:56:51 AM »

Has anyone had any problems using 1/2 a propane tank for the fire box?  We had some problems welding the tank to the faceplate of the fire box.  Any place the tank was welded to regular carbon steel we had more leaks.  I heard the you have to heat the propane tank prior to welding it because it is a high carbon steel.  Hope I don't have any problems in the future between the welds.  Do not need any leaks in this thing.  Thanks
