GREAT WARMTH IN THE DOWNSTAIRS LOUNGE DINING ROOM KITCHEN, UPSTAIRS 4 BEDROOMS 10 DEGREES LESS, BALANCED CORRECTLY, AIR FLOW SEEMS TO DIMINISH AS IT FLOWS ALONG DUCTS,
WOULD I RECOMMEND IT ? YES IN A BUNGALOW, NOT IN A HOUSE.
I have to disagree with you there.
The whole problem with your system is that it is NOT balanced.
Can I suggest a simple test for you to do as a DIYer?
Totally block up the lounge vent and then all the hot air will be directed to the bedrooms!
Please do that and then tell us if that does not happen.
