"Makes sense. Egt could be very close to as low as return water temp, not supply water. My indirect seems to satisfy when return temp hits 115f."

"Biggest pro is to keep the clay or brick or high mass chimney warm  with the 4-8" flame.   We can waste 50-70,000 BTU hr just to keep the flue working. If firing rate = 100,000 Btu/hr and SSE = 75%, then 75,000 Btu/hr go to the…"

tedkidd replied to Barbara Smith's discussion Furnace with ECM: How to Model in the group HVAC
"Barbara, You model the blower motor as an "appliance", then the ECM becomes an "improvement". Put some of the furnace cost to the blower improvement (say $1000). As Bob alluded, there are quite a few "it depends" when…"

Bob Blanchette replied to Barbara Smith's discussion Furnace with ECM: How to Model in the group HVAC
"There's more to it than that. The blower efficiency gain comes using an ECM for low speed vs. a PSC on low. On high speed the power difference is negligible. ECM is chosen more for comfort than energy savings. ECM vs. PSC payback time simply…"

Furnace with ECM: How to Model

Suppose you have a forced-air natural gas furnace.  At the end of its life, you are considering replacing it with an ENERGY STAR model.  In the cold northern states, that means 95 AFUE with an efficient furnace fan motor (blower), often an ECM.  How do you model this change to determine cost effectiveness?  Or to give your program "credit" for the energy savings?  You want to get credit for both natural gas (heating fuel) savings and the electric savings due to the motor.  If ENERGY STAR…See More
