Hi all
Thinking of getting hrv....we live in an old home..no double glazing....
Is it really worth getting HRV or is it all just hype?
Anyone here recently got HRV installed? Anything you could recommend or to watch out for?

shrub: Just remember its a fan in a box..... But it does work very well and keeps the moisture out by forcing the dry air down.
andrewNZ: NO. Positive pressure ventilation is a scam.
I have just unplugged the one in my house (installed by the previous owner) and my house is now a LOT warmer with no noticable increase in condensation.

Take it that the dry air comes from the roof,therefore i need to make sure insulation in the roof is 100%?

shrub: With the new HRV systems they they have sensors that will turn fans to very low/off when the roof temp is lower than the house temp. It all depends on the installer that does the setup some are rough as and the systems are not programmed properly it will not work.
Lots of people say they don't get the crying windows anymore, but is that because of the air flow that is created? or due to a real decrease in the humidity in the house?
