Can't understand why anyone would want to do this.
As with all energy products prices vary greatly from year to year.
Propane. You don't own the tank. Some charge a rental fee.
Every time you change companies the tank has to be changed.
A charge to empty the tank. Another charge to remove the tank.
And big trucks driving on your nice lawn every time you change companies.
You can purchase the tank but that is about 2 grand just for the tank.
Best to do a real cost analysis.
What is the actual payback.
You already have the infastructure for oil.
Now you are going to have yard dug up for piping.
Probably different venting.
The high efficiency ones usually reguire venting through walls.
If vents are not high enough - snow will cover them up - and a failure of system.
Do you have ducts for hot air?
Also check out BTU units. Propane is near the bottom.
A lot of money spent and for what in the end?
