One reason I switch to ec bonus is if you go with a ac infinity and have the Bluetooth controller you can have it dynamicKeeno wrote: ↑Thu May 26, 2022 12:21 pmI'll be converting to EC fans as part of my attempt to reduce costs. I've put together some numbers below of AC v EC fans to show you what got me excited about, especially with rising energy costs. Moving from 6 - 8 inch fans.
-----------------------------------------------------
6 inch AC fan
Power consumption: 59.6 Watts
Rated air-flow: 428 m3/hour
6 inch high powered AC fan
Power consumption: 109 Watts
Rated air-flow: 720 m3/hour
6 inch EC fan
Power consumption: 42w
Rated air-flow: 560 m3/hr
-----------------------------------------------------
8 inch AC fan
Power consumption: 104 Watts
Rated air-flow: 796 m3/hour
8 inch high powered AC fan
Power consumption: 153 Watts
Rated air-flow: 1008 m3/hour
8 inch EC fan
Power consumption: 90w
Rated air-flow: 1230 m3/hr

Ive listed both high and low power AC fans to give some scope to the most important factor in my changing to EC.
I would say from years on forums that the most commonly used extraction fan size is 6 inch. The 6 inch EC fan is far better than the AC as you can see above. It doesn't move quite as much air as the high powered AC fan, but it runs as a much lower wattage.
I have instead jumped upped to 8 inch EC fans. I only need 6 inch as im sure the vast majority of members here would. But.. by running the 8 inch EC fan at half power you will be moving as much air as the low powered 6 inch AC fan, almost as much as much as the high powered AC fan. All while running at less than both in power draw. You will also have a much quieter system running fans at half power.
I'm doing a full write-up on this once I've got my new ec fans.
I’m got a 4inch and avg around 3-6w power used as on 1 or 2
Otherwise run overnight should be abit cheaper as not peak time
