Hello Folks,
This is my first post here but I’m sure it won’t be my last. I have decided to install a wood gasification boiler with storage in my home next year and I need some help. My current oil fired hot air furnace has a cracked heat exchanger (hx) and I need to replace the unit in the next two weeks. When I have the new unit put in I am going to have the sheet metal done for the hx as well. I currently have a hi-boy furnace and I’m thinking of replacing it with a low-boy so I have room on the supply side for the hx. It is going to be tight even going with a low-boy but it should work.
Here is my question to you all. The plumbing supply house told me that I could put the hx on the return side of the unit if room above is a problem. This sounds good but my concerns are having 160-180 deg. air going across the blower. Is this ok? Am I going to loose efficiency this way? Is this a bad idea? He also told me that this would simplify the thermostat setup and I could use the current one. He also told me that I could adjust the furnace control so when the house calls for heat the blower would come on and the heat from the hx would cause the oil burner not to fire. Is this correct? Any help would be greatly appreciated. Also, I’m looking for books or web sites that will help me with the installation of the boiler, boiler controls and hardware, and water storage sizing.
Thank you,
Ken
