too small for 2800sqf house
"this unit is too small for my house i burned 11 cords of wood with my outdoor wood boiler after installing this. i have never burned more than 5 cords. my boiler was piped as an open loop to be diverted by a 3way valve. i used this exchanger to close the loop so i could pressurize the inside loops in the house as i had issues with vapor lock, and also run glycol in my wood boiler. this year i will be upgrading to the 450,000BTU unit. overall this product does what it says it will and is constructed well. it would be nice to have an in and out indicator on the connection points."

Ask a Question
Is there a schematic to indicate which are the supply and return ports or is it assumed that the top is supply and bottom return?
Helpful? Yes No
If you stand the heat exchanger vertically (with longest sides being vertical) then connections are as follows: Left-Top - Side 1 Inlet; Right-Top - Side 2 Outlet; Left-Bottom - Side 1 Outlet; Right-Bottom - Side 2 Inlet; In essence, the left side in 1st liquid and right side is 2nd. It is generally advised to run the liquids in opposite directions to achieve higher efficiency, but same direction would also work.
