Up until last year, it was all electric baseboard heat plus a fireplace with an insert - until a chimney fire caused us to rethink the entire wood fire thing.
Now is HVAC with 23 SEER heatpump and 98.5% nat gas furnace. Heat bills are already looking like about half of last year's bills. You don't wanna know what it cost to put the ductwork into a 5-level, 4,000 sq ft split to accomplish this.
Shop is radiant floor heat in the concrete, Nat gas boiler running it.
Nat gas boiler for the pool, but that thing goes through more gas (and more $$$$) per day than the house & shop combined use in a month!
