That is reassuring to hear , I should be fine with this units reduced outlet flow

It was a rush purchase they were almost sold out of the single hose units with just 1 left so bought it haphazardly spuriously after quickly deducing it would be better of the two styles for winter heating.

I'm hopeful it will work fine its good to get some input on heating as most people cool with these it seems.

A electric heater down in the rec room heats up the top floor real nice. If I don't heat the basement room the stairway and front door area are chilly all winter long. That air mixes with the living room kitchen and dinning room air.

So with it will be heating 1/3 the basement and the 2/3 of the top floor with 1200w of juice.

That works out to $55 @ 12hrs use or $110 @ 24hrs continuous use.
The coldest months pay as much $300 per month with baseboard heating , $1200 a yr

The owners of the dual hose models defend them strongly for summer cooling I have to agree with those arguments as the temp difference is only 20 to 30 degrees.
Where as winter temps are more like a 60 to 70* difference.

It will be vented from a pellet stove outlet left in place from the previous owners. Currently has a 4 inch vent the AC vent is 5.9 inches.

First thought was to use a 6 to 4 reducer after reading up on it appears it may cause too much of a restriction

In my head I deduced a 4 inch outlet would reduce the airflow by about 1/3 which should reduce the air infiltration by the same amount.
A win win I thought before reading papers on airflow vs pipe diameter.

After checking it looks like a 4 inch vent might reduce the airflow by 50% to 70% if I understand it correctly.

So its looking like I will use the same size vent outlet to keep the units efficiency up.
