Made a lot of progress on the hot tub hook up.  Been a work in progress for about 2 weeks now!  WAY too many trips to the hardware store for fittings.  I ended up running a very similar setup on my pex from the garage to the tub.  It's about 15' this time with 2 - 1" pex lines in a 4" corrugated pvc pipe.  I used the same 4" roof vent flashing.  This time it went much faster!  It's a whole lot easier doing 2 pex in a 4" line than 4 pex in a 6".  Only things left are the pex connections to my main line and the pex connections at the hot tub.  I may have to run new electric so I can leave my 220 box for the tub alone.  I'm waiting for 1" pex cinch rings.  Apparently, my town of 18,000 people doesn't have enough 1" rings to supply 1 stove install!  I've bought everyone out! And I started with 50 from online!

 You're going to like your tub with OWB heat John, soaked for a while this morning in mine. The temperature regulation is not quite as precise as electric on mine but still within a couple degrees, have been experimenting to keep it a little closer.
 One caution, you may already know but 104 is as high as tubs are programmed to run because of threat of hyperthermia, once you have the boiler running it you can really let it fly if you wish, be careful if you have others especially kids and expose them to high temps for an extended amount of time.

Got my first bill after a full month of running the stove.  Not quite what I thought it was going to be.  Last year, same bill cycle my electric was $283 and 2594 kwh.  This year it is $140 with 1122 kwh.  Last month my bill was $112.  My "new" electrical components added more power than I was expecting.  I guess 2 furnace blowers, 2 pumps, and a stove fan draw more power than I was expecting.

Hot tub is hooked up, filled, and fully operational!  Man, that was a pain!  I think I spent an entire month hooking that darn thing up.  I hope it pays off!  It didn't quite hook up like I was expecting.  I ended up having to disconnect the hot tub heating element, because it wouldn't run the primary pump unless it was calling for heat.  So, I have my "stove" thermostat set at 102 with a 2 degree swing and my hot tub set to 102.  That way the pump will cycle through the exchanger when the stove thermostat is calling for heat.

I received my second bill yesterday.  I tell you what, I get a little excited when it gets close to this time of the month!  Anxiously waiting for my electric bill to see how much I saved over last year.  Last year: 4,000 KWH, 129 KWH/day, $420  This year:  1,254 KWH, 42 KWH/day, $153.  Last month was $140 and I started up a hot tub pump that runs pretty much 24/7.  Also, i bumped up my stove temp from 175 to 185.  I think that made my recovery time in the house quicker, which made up for the more times it had to run because it was so firggin cold this month!  I seriously think that $150 is going to be my winter average.

Sounds like you're having fun! 
One suggestion is to box in and insulate your lines from the stove to the house.

[CountryBoyJohn]

Mr. Dragfluid, the lines from the stove are insulated with the grey pipe insulation and they are all 4 zip tied together.  I have considered drilling holes in the bottom and injecting expanda-foam insulation to increase the insulated value, but I don't think the benefit and heat loss prevention will outweigh the risks of water penetration with the drilled holes, even if I silicone the openings.  I actually have snow that sits on the PVC for a few hours before it finally melts off.  Additionally, it's 8'.  I doubt I really loose enough heat to justify any additional insulation.  Thanks for the input!

Heatmor or Heatmaster?   2 different companies

I uploaded a short video of my first go at coal.  I'm working on uploading another video of my whole setup.

Nice vid, keep them coming, put em in heatmaster section as well

[roxann]

I need some help again....

I have constant water overflow coming from the flue does anyone know why?

Also I am having water flow issue the pumps are getting hot

[slimjim]

 It's Richard, Do you still have my number?

[roxann]

No

[RSI]

If water it coming out the overflow and boiler losing temp then it is most likely a failed DHW exchanger. (sidearm or plate depending on what you have)

If you have a valve to shut off the water supply to the heat exchanger, that would stop the water from coming out.

[slimjim]

Roxanne I'll give you a call later today, if I recall RSI she had a sidearm and good call on the domestic!
