Need a pro here.


I built this fire place ,a full masonary one ,out of creek rock with a 11 inch square flue liner (rounded corners) and I'm thinking about putting 3/8th soft copper coil in the upper five feet of the liner, no brazing inside liner and connecting to a pump (what size)? and connecting all to the A coil thats never been used on the furnace. For the liquid I'm thinking about using cooking oil (the cheap stuff) that has a boiling point (smoke point) at 550f . Want the propane furnace as a back up ,but would like the blower to come on when fire place heat is needed. Any help please.

A sure way to make sure there's nothing left to save when that fails and starts spraying out a burning liquid.
One chimmney fire and the whole fire box fills with hot oil that dumps out on the floor.
No insurance company, building dept. fire marshal would ever sign off on this one.

A reguler fire in a fire place can reach 1000 deg. A chimmney fire can be 2000 deg. plus.

A fireplace by far is the least efficient way by far to try and heat any home, and to get this thing to work that would mean you would have to build a fire even is the summer time.

As said, using oil is unsafe.

Proleune glycol could be used. It doesnt burn. You alsp neef additional safties for pressre and temp situations.

Thanks for the opinions. I"m not giving up on this idea just yet, but I do have to think of other families in the future.
