Badger Pipe has 30 plates with  inch ports. For some reason I thought you already moved after I dropped off your pipe years ago.

So that 10 plate exchanger I linked above is 12" long with 1" nipples.  The 30 plates that I can find are 3"x8" with 3/4" nipples.  Will the 30 plate still have less head pressure?

Juddspaintballs, so you sold the place in the mountains? I liked that location, Where did you go from there?

Nope, still here in the mountains.  I used to live in Maryland and I had the Heatmor there, too.  I am trying to move in a year or so, but I'm not going far from where I am.  My parents bought a farm on the other side of the mountain and we're all going to live on the farm.  My dad has his boiler running there already and I'll be taking mine with me (again). 

130-140 degree water is pretty darn hot and with the plate exchanger they will never run out.

I had an interesting call yesterday, a 3x8 30 plate preheating into a 40 gal water heater was tripping something on the dishwasher (too hot). Anyone seen this before? It's a first for me. Wondering if I should just out a point of use mixing valve in at the dishwasher. They love the hot water in the rest of the house.

RSI is right on the head pressure, typically when I set them up I use a 30 plate and use a mono flow tee in the wood boiler loop for better flow.

Well well well, it seems that now he finally is being taken seriously by HeatMaster and they have made an offer but it’s a shame that he had to go to this extent huh?

Go with a 20 plate instead. A 10 plate will add a huge amount of head pressure loss.

Slimjim, at my old house I had to reset the breaker on the water heater when I shut down the boiler because the water was that hot.  I was using a sidearm exhcnager with a stainless Taco 007 to circulate the tank.  This house, it's just passively heating the water inside, though I think it still gets up to the same temperature eventually.  I never have to reset the breaker on this water heater.  I do have a mixing valve to tone the water down to about 135 degrees, which is still pretty hot but not ~160 like the boiler's low set temp is. 



I'm looking at the 10 plate exhanger from Anderson's.
