Heat Distribution System
Living Room Heat Pump

About the Photo Sequence
The fireplace is a firebox inside a containment box called a "Zero Clearance Fireplace". Air is blown into the airspace between them, them blown into the living room. The previous fan setup was two inline duct fans and they did OK, but eventually became noisy. Also, they never moved enough air. This job replaces those fans with a swamp cooler fan. This page documents the build and installation.

Photo Details
This photo sequence contains 7 frames. Each landscape frame is a finite 1600 pixels wide but height was left to its own based on the crop. I based the picture size on an email program's display window asuming that the picture would not be automatically resized to fit. This technique kept the file size down, the largest being 1616k making it easy to send and receive through email. All photos were taken with a Nikon D810 or my Samsung A52 cell phone.

Heat Distribution System
Living Room Heat Pump

The previous fan worked, but not enough airflow and it was noisy.
I replaced it with another swamp cooler fan I pulled from this unit:

Like the main, larger fan, I built a box around it. I measured the current draw and wrote it on the fan housing.

The wiring conforms to code.
For extra protection, I cut ~6" of insulation off a Romex 10 gauge wire and fed the wires through it.
It'll be further protection from the metal of the Romex clips on the junction box.

Finishing the containment box, I mounted adapters for the 8" ducting I'll attach during installation.
All panels are glued and screwed in place. All but the one panel for motor access. I hope it's never necessary.

This panel can be removed if I ever have to fix or replace the motor.

Ready to haul up into the attic.

I placed it on top of the Heat Distribution fan. It's above the hallway and not above the bedroom.
That way the bedrooms will be quieter. Surprisingly it pushed less air movement than I expected.
But the room gets warmer!

A future project will be to connect the inlet of the fan to the furnace ducting.
Then, the air blowing INTO the fireplace will be 85° or more rather than the the temperature of the attic air
which isn't much warmer than outside.
