Sorry people: They are having a lot of trouble with these. defective dampers Need air bypasses etc. I really wanted to try these in my business but decided to wait until I heard of any problems. glad I waited. I was very leary when I heard they needed no bypass. Well, it sounds like they do! lol
Old type of workinq! Now its Better.
3800 for the 2500 square ft bundle on the ecovent site woof
i can hear the whistling in the room I'm sitting in now when the other rooms choke off LOL
After reading all of the comments from the so-called experts on HVAC I have just one question. If closing the supply vents will destroy the blower motor hit the limits in the furnace/ac unit etc., etc, why do I have manual controls on the all the vents in my home that allow me to do that very thing. With the room zoning controls, I can now centrally control programmatically via wi-fi what I was able to control manually.
it sounds like the engineer forgot one thing, most people are saying they need a bypass and that is correct for a non variable Hvac. In order to do it without the bypass you need a designed hvac for variable speeds to not over-pressure the flow. You need a max capacity btu but a variable fan speed. There will still be disadvantages, cost is one of them. size of the evaporator is another. A bypass could also be a good thing if they integrate a water heater into the loop instead of being a separate unit. I don't think current systems will not manage unless major deterioration happens. Plus modifying a hvac system vs designing one from the ground up will be better.
This seems fishy the proper way to zone a system is install ducted zone dampers for each floor at the system.
Super cool tech!
any update on needed bypass???? How to contact vender?
What about the static pressure in the duct or friction when the dampers close? What about the return bypass? Only good for a module home or studio apartment
