Hello all,
I inspected a house yesterday and saw something new...
Had a Heil heat pump unit (it was 8 years old), but the seller said they didn't like the electric resistance heating as backup heat since it was too expensive, so they configured the heat pump emergency heat to run off their LP tank. I'd never heard of this before.
When I inspected the furnace, I noted that just past the burners, in the tubes, the "diffusers" were odd-shaped and actually looked like they were partly melted or something. It's difficult to describe, but imagine taking a sheet of metal, punching holes in it, then wrapping it in a cylinder...that's what they looked like...but then they were "eaten away" at the front end.
The flames came out of the burners blue, but when they hit those metal devices that I'm calling diffusers, they turned an orange color. I have already specified that they have an HVAC tech evaluate this, but I'm wondering for my own knowledge if anyone has seen this and what that setup is.
All photos below are of the same thing, just tried to get better lighting and focus.
Thanks,
Dave
