what do you use for heat

Boy have i got this one covered. Outside i have a Hardy wood burning furnace that heats the house and shop. It's a stainless steel unit that sets in the yard and heats water that flows under ground to a radiator placed in the duct work in front of the blower. The shop has one also and does a hell of a job for the price of beans. In the house i do have alternate systems that will kick on if i were to be gone and the wood burned out. I have the heat pump with the electric strips. In the system also is a Hi E gas unit that runs on propane. Use it very little. In the master bath we have a ventless 3 plank wall heater for the times the ice kills the power. In the kitchen we have a very large commercial stove with 4 burners and a 24" griddle. In the car storage 3 car garage i have another 3 plank ventless heater that i keep on very low so as to just keep temps bareable. Some of you guys with high energy bills might want to consider a waste heat recovery system. Something as simple and filtering the exhaust from the clothes dryer in the laundry. Being a Building Contractor i think on efficiency when i can so as to cut that bill down. In my spec house i'm working on i have been toying with different methods of heat. I have now found my solution. A buddy of mine has a recently rebuilt Geothermal unit that the EPA wont let him run because of lack of area for the unit so i'm putting in a leach field for his septic system and he's giving me the unit. I've gotten quotes from HVAC people of $25000 to sell me one. Some of our banks are adding $25000 to the appraisals for that system being in the house. I could sure use that.. I think i have it covered. Let's start a thread on Waste Heat Recovery systems so some of our friends here can realize more hobby money in their pockets.
