Before calling the dealer I looked closer at where the leak was, it was actually a SS clamp that needed a little tightening. So all is well.

I did call the dealer. He ordered me a 20 plate and will sell me some fittings and Central pex pipe to install. He's recommending a bypass line and shut off valves to be installed on it also. I'll drive up Friday to pick it all up.

Moving the temp probe is working well now. With in 1 Degree of boiler temp now.

RSI, I never have used a mixing valve. Most people want the extra hot water and if they don't I explain to them they can control it by lowering the outdoor furnace temperature. I set the furnace rather low and if they want to adjust it they can.

Yoder,
  Don't you worry about young children being scalded if you install w/o mixing valve? I did not put one in right away and when I checked my hot water with my brides digital turkey thermometer the temp was 131*. That is plenty hot enough to scald. My wife made me install one a.s.a.p.(we have a 9 year old who was only 4 when first boiler and side arm were installed)
  P.S. Expensive digital turkey thermometers can not withstand being dropped into scalding hot water! Only the probe is meant for that kind of environment. $28 for new one.

On Friday (April 22nd) I picked up the parts to install a 20 plate HX. The HX is being dropped shipped.

HX, Fittings and 36 feet of  1" Central Pex was $365 from the dealer.
CPVC parts to add bypass lines and additional accessories (Pipe dope, insulation, valves, adapters, elbows, T's, mounting brackets, ect)  was $90 from local Hardware store.
Labor is free.

Total investment to add DHWX $455. Since the OWB is only going to operate in the winter, it will be next spring before I see any return on this investment.

 Marty,
 Almost all of my customers are looking for 130 degree water that never runs out. In fact I have had complaints before that the water was only 130, some want 150. I always explain in detail how the system works and that increasing the temps on the furnace will result in hotter DHW. If a customer has small children and is concerned about the hot water they run the furnace at a lower temp then normal and it works well.  I can't tell you how many times I go out to install a furnace and the customer tells me the thing that his buddy bought one from me and brags on the hot water. Most people are amazed at the idea of having continuous FREE hot water. I installed a hot water spigot outside my home and use it in the winter for washing furnaces before I deliver them.  I've had that water running for hours before without running out. When we do shows we burn a demo unit and display both heat and hot water, always helps sales when they can't hold their hand under the water.

Looks like I paid off my investment early. Just got a check in the mail from Amerigas. We had a 100 gallon tank used for the pool heater. Since we don't have the pool any more I told them to come get the tank. They topped it off in Decemeber.

Refund (After restocking charge and taxes) $504.68  So I came out on the plus side for this project.

Here's the install of the DHWX. I'm currently heating water just to test it.

Ridgekid,
Is your HWH off? If not, why bother with the expense of a HX. BTW, if you don't use any hot water in lets say 12 to 14 hours (presuming HWH is off), do you get any hot water after it mixes with a tank of cold? Should have just plumbed the HX "inline" in your hot water line out of your tank. Then you would have an on demand hot water system.
unless I am misreading your pic

dirtryder-

To prevent scalding and the additonal hardware to install a DHWX, I am only pre-heating the water before the HWH and thats only when the OWB is on. 

The DHWX is downstream of the Furnace HX. Heating the house is more important than the HW. I am not running the OWB year round.

I consider the DHWX as a bonus. Anything it can provide would be beneficial.

Saying that, yes I will be leaving the Electric on to the HWH. If I am preheating the water, the electric will not operate as long or often. Be advised my HWH has been on a programable timer since day one. It only operates 10 hours a day.

[dirtryder]

OK,
I see what you are doing now.  I have mine in an "on demand" type set up and have never ever run out of hot water. Just didn't know if there was something I was missing about heating the water going "into" the tank. I guess it just depends on what we boiler burners want to do.

BTW, my boiler water goes to my DHW hx (10 plate) first, then to a 90k btu tube and shell hx for my hot tub, then to my first water to air hx, then to a second water to air hx then returns to boiler. 2 completed heating seasons and everything is working great.

Big system. Yet I see you have the 6048, so it can probably handle it. How was your wood usage?

I see Redi Chek makes a dual probe monitoring system. (ET-7)  I'm going to get one to put on the Copper pipes going in and coming out of my HWH.

I have only been running the 6048 since the begining of March. Prior to that I had a HE5000 Wood Doctor Gasser. It was a great unit but too small for me ( had to wait till 11pm to fill for overnight burn during winter) so that's why I went bigger. I used about 10 cord last year and this year and believe it or not, I have been putting less wood in the 6048 but I know that it was due to me "stretching" the heating capacity of the WD. Next winter will be the "real" test for the 6048. Yes, it is a large heat load........... I heat my 24 x 32 garage with it too.
Here is the temp monitor I put on my lines where they enter the house.

That looks like a very nice unit too. I needed the remote monitoring as not to have to go to the basement everytime I want to see whats going on.

Two full days on the OWB and DHWX. HWH is hot! I checked and had 158* coming out the faucet. (After heavy use). After sitting overnight it was 150*.

Somewhere I read how clean the dishes get in a dishwasher... they are so right! Ever do a load of dishes after a spagetti dinner and have a red tint stain the inside? After two loads with HOT water the inside looks like new again!

The wife loves baths. HOT ONES! She actually said (for the first time in 18 years) the water was TOO HOT!

The daughter said she used to put the shower handle 1/4 turn to the hot side, now she can leave it in the middle when she showers.

And of couse this only means one thing! I'm not using electric to heat the HWH, and that makes me happy!
