New Member, what a great forum you have here. A question about hybrid systems, combo gas and heat pump. I live in the western suburbs of Chicago , our town buys its own electricity wholesale,cost .073 per kwh,gas is local utility at .92 per cubic meter w/ the delivery price included.Does anyone know where I can run some numbers or does anyone have experience if these types of systems will save me money and get some payback over a 10 year period. The house I have was built to my specs, it is 3500 sq.ft.,I insulated it well, a local HVAC , did a load on the house for air infiltration and said there was no need for any extra insulation (he said it was close to needing a heat exchanger it was so tight )other than sealing the ceiling lights which they did. In talking to my neighbors my current bills are 1/2 of thiers, I average about $175.00/ mo during the heating season and that includes a heated 3 car garage kept at 50 degrees, my electric bills average $100/mo during the summer. My current system is 20 years old , it is a first generation 90 plus gas with 13 seer a/c .Would a hybrid system work for me, or can some one direct me to help me with the numbers or decision.
thanks I have been reading al night on the forum to see if someone had answered this question, but I could not find anything this specific.
