I live near Bourneville Oh and I am considering a new heating system.
I am not sure what would be the best way to heat my home. I have
2000 sq ft ranch, 30 years old. I have had 2 units in that length of
Time. LP gas cost is no $2.65 gal. Base rate for kWh $.074900, consumer
Charge $9, rider adj $8.01. Should I consider a heat pump or an lp gas
Or electric furnace with separate air conditioner?

Most quality HVAC companys will run a utility usage report for your home. They usually do this at the same time they do a manual J to be sure the size of the equipment will be correct. If they do not know what a manual J is then call another company since they do not know what they are doing.

Chillicothe is close to where you live.

Due to your construction type I would get the heat pump with the 90+ LP gas furnace. This is called Dual Fuel. The heat pump will do fine in cool weather but when the real cold weather hits you will have that LP furnace to pick up the slack.

When they run the numbers for the utilitys it might be cheaper to use electric but a manual J needs to be done to calculate heat loss.

A manual J takes into consideration

Window size and R value
Window placement north south east or west
Wall insulation
attic insulation
Exact sq ft of heated area
Door sizes and placement
ETC.

It is a very exacting science and necessary. Many years ago they did not calculate the furnace/AC size accurately and the units that are there now could be to big or to small. They usually were to big and that cost extra energy waste. This is the reason to get a good quality manual J done to prevent these errors from happening again.

With your KWH to propane price ratio I'd go with hvac1000s recommendation. It will give you the greatest comfort at the lowest seasonal cost and provide a hedge against fluctuating LP prices.

Can't stress enough the importance of getting a Manual J. If the equipment is too small you it won't do the job; too big and it will run up your bills and cause comfort issues. Run don't walk away from anyone that doesn't know what that is.

When you get some quotes, and I recommend at least 3 from varying brands, re-post what was recommended and we can help clarify the choices.
