I am in the market for a new furnace and was considering a two stage LP unit. I have a heat exchanger for a solar water heater in the duct above my furnace. The furnace blower is connect to a relay which turns the fan on when my solar system can provide heat. Anyway, several contractors have now told me that my solar exchanger provides too much resistance to allow the two stage furnaces to work. They tell me I must settle for a single stage due to increased static pressure in my ductwork. Does that sound reasonable?

Just want to know what my options are. I've been told my exchanger is significantly more restrictive than an air conditioner exchanger.

What is the ramification of too much static pressure? I have a contactor that is proposing to install an Armstrong 95% 2 stage and assures me that there won't be a problem. 10 year parts and labor warranty. He did mention that they may have to put a register in the basement ductwork. Not sure how that helps.

Two stage unit seems appealing to me and qualifies for rebates.
