Did anyone have to turn up the furnace blower fan speed to accommodate the added resistance from the heat exchanger? With these multi sipped furnaces is that a good idea?

 I have 5 water/air HX's set up and have not had to increase fan speed on any of them.  I've not seen any way to do it anyhow.

I have a 4 speed fan on my furnace.  When the oil furnace runs, which it rarely does, the fan is on it's highest speed.  When the OWB is in action, the fan is on it's lowest speed. Just the way I hooked it up.  I have no problem heating my old farm house -  Central Ontario.

i have (in the house) a "water furnace" that runs in low speed all the time to recirculate air, it only kicks into hig speed when the water furnace thermostat calls for heat...that has not happened in ten winters and the house has never been uncomfortable. i think your OWB will do fine on what ever speed the fan is running. remember as long as there is wood in the stove the btu never quit comming. as long as yoru blower is pushing enough air over the exchanger to overcome your heat loss it will be fine. i like the fan running in low speed, it is much quieter than when it used to kick into high

If it is keeping your house warm on the low speed it will be able to hold it more even. Only reason to go higher is if you aren't getting enough heat or it isn't making it to the far end of the ductwork.

I have a variable speed air handler and I have it set at low speed but if the temp difference gets below 2 degrees then it will go to a faster speed to recover faster. Once it gets back to within 1 degree it slows back down. Really makes it nice as it will save the life of the motor.
