Is there an equivalent system to this one in the US?.
The system that I'm talking about can be seen at http://www.ventilation.co.nz/dvs
The reason I ask this is because I have installed a few of the Dri-matic systems, which are pretty much similar, just a competitor company and I was wondering what sort of results, were obtained over in the US. [Linked Image]

Hello Trumpy, this is a new one on me but I'm curious now. I don't think anything will help my old drafty house, but I would still like to see some opinions on these systems.

What is the concensus in your neck of the woods?

Not sure if one of the systems these guys offer is quite the same, but similar in concept of having clean air in your home. These things are increasingly common in our area now.

Gidday there Roger, [Linked Image]
Yeah, the results I've had back from customers of the systems I've installed, vary from OK to "Don't even realise it's going!".
Mind you though, NZ is probably the worst country in the world for Condensation inside houses, anything is better than nothing to combat the problem!.

Sandro,
These systems suck air out of the roof void.
Over here, the air temperature in these voids is often quite higher than the room temperatures.
There are extra heating elements that come in at 5 degrees, these are rated at 1kW.
It works on the assumption that the roof void temperature is at least 10 degrees.
And this is very dry air, too!.

In my neck of the woods in the North East USA, we want to echange air with the outside and recover the heat from the inside so the fresh air doesn't have to be reheated. Generally humididy during the winter is not a problem here, except maybe a bathroom shaower. http://www.nu-airventilation.com/specifications.html http://www.guardianplusairsystems.com/docs/GSHH3K.pdf http://www.fantech.net/hrv_erv.htm http://www.americanaldes.com/HRVRes.html
