Hi Folks
I am sure there as many ways to do this as there are people on here and they will all work.
I may have help install a outside wood furnace to an inside oil boiler. They have a heat exchanger and want to hook the oil boiler into the exchanger and hook outside furnace to exchanger and circulate water all the time.
They claim they were told the only thing they had to do was hook up the exchanger and make no other connects to wiring or anthing else.I feel that burner will have to be shutdown or it will try to start if temps of water went down....
Anyone familiar with good way to do this?
I think I would have done without a heat exchanger by circulating furnace to furnace
Any thoughts on this . Any place I could find a diagram on "how to"
PS They get Hot water from a boilermate so that is not a problem.
Connecting 2 Boilers or Hotwater Furnaces

This it the typical method for tranfering heat from an outside boiler into a house. The beauty of this method is that the house's current boiler, controls, and water are not touched or interfered with. You just put the heat exchanger in the cold water return line in the oil boiler's system.. Nothing else changes.
You don't have to try to connect the outdoor circulator to the oil boiler's circulator, the water in the underground tranfer pipes doesn't get cold, and this water is kept separate from the oil boiler's system.. the outside wood boiler is typically a non pressureized system, while the oil boiler in the house is pressureized..So you HAVE to keep them separate.
The only disadvantage with this method is there is some heat lost by the underground pipes, and the circulator running 24/7 burns about $10-$15 per month. This is more than offset by the fuel savings
