Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
DC area ..

  • Fossil Fuel system:  90+% efficiency gas furnace plus a SEER16+ heat pump, with controller choosing between electricity & gas for heating efficiency based on temperatures (and prices)

  • Radiant floor heating for one portion of house

  • High-Efficiency wood-burning fireplace (haven't used it yet) -- partial of heating load -- only using wood cut down within walking distance (e.g., neighbor's trees)

  • Controller:  10 degrees C (50 f) when house unoccupied; 16 deg C night (63 degrees); generally 19-20 deg C occupied (67-69 F). (Note: young children, driving to higher temperatures.)

We replaced our gas furnace last year and chose an 85% unit vs new high efficiency 90-96% side venting on advice of several installers.  They said extra price and efficiency didn't justify the extra markup and complexity/reliability issues of high efficiency units.

We did get a variable speed, low voltage blower that should save some plus it improved the efficiency of our SEER 13 AC purchased the year before. Difficult choices, and the estimates I got for the same equipment were amazingly far apart in price, as much as $1500 for the same furnace.  Unbelievable!
