General Outdoor Furnace Discussion / Re: New guy needs help with heat loss!

True there is a tempering valve but there is also a large valve that has a themostat wire that opens and closes as the addition calls for heat. So no there is not a seperate pump for the infloor. The outdoor boil water is the water going threw the 3  -  1/2'' loops. Right or wrong this is the way it was setup and it seems to work as long as its no -10 or colder. Thanks again guys. Happy cutten

Plumber supplier is going to drop me off a new pump tomarrow. Not sure of brand but he said it is the same as 007 taco but this one is a three speed. ITU could you explain the HX backflash a little better? The infloor was calling for heat when I did the test but I think I does most the time. The 1" pex runs to a manifold were it goes to 3 seperate 1/2 " pexs loops threw the floor. Thanks all for the help and glad I did not buy a heat gun. I was using a instant read meat temp and it read the same just took a little longer. Thanks again. Oh i live in NE Iowa & more cold next week.

It seems like I don't have as much hot water on tap like I use to. 3 years ago put in new water heater and redid side arm. There was some limeing up in some steel fittings so now its all copper or pex. Checked it last year and all looked good. I have always figured kids getting older they use more cloths and hot water in shower. 7 years ago put on addition with in floor heat so after water goes threw in house boiler it goes to switch valve that returns it to outdoorboiler or makes it go threw mixing valve that is set at 120 and then threw 18 x 45 concrete addition. Then it returns at that 107 F. When I checked the temps with heat gun I tried to keep same distance and angle but diffrent maiterials was hard to control. Then I did the addition I added sq footage but i got ried off 2 old doors and 2 large windows and got things insulated better. Any more ideas would be great its -14 outside this morning. Thanks

I have a Woodmaster 434. I bought this new in 2001. I think my heat loss is to much. The burner is about 80' from house with 1" pex in insulatd pipe 24" deep. My dail says 166 F the upgrade digital stack switch says 169 F and the outlet water is 168 F with heat gun. Now to inside the house. Feed line inside the house is 150 F. 145 F at the waterheater and 160 F at heat exchanger. Pex line going back to wood burner is 107 F in the house and 104 F at woodburner. The boiler in house reads 138 F both with the gauge and heat gun. I listed all the readings in order as they are hooked up. This stove has the orignal Taco water pump. Thanks for the help.
