LF HRV installation pictures

[vaporize]

HRV is absolutely the way to go, out of the 1200 gallon or so different tanks, it used to be around 60-70% humidity even with full dehumidifer. In the winter months, it drops to around 30-40%.

Unfortunately for the summer months it gets to be a bit of an issue. Nice installation pictures. and Seriously labour is crazy, I think I was charged $1000 alone just in labour.

You guys ever have your fresh air intake line condensate so much that the plastic wrap that holds the insulation around it fills with water? Mine did this winter , i dont want mold there, what slope direction does yours run. Mine is metal piping 6 inch and solid piping also for the corners it runs about 10 feet from the exterior wall to the HRV. Any solution for this.
Thanks

do you have a drain at the bottom of the HRV?

[bkelly]

yes set up just like the photo in this thread. I think mine is water coming off the pipe leading to the HRV, i have a slight slope going to the HRV on that pipe but not much as theres a door in the room the pipe has to clear.

So what do you figure is a fair price for two guys for a day? A grand is fair where I come from. Good on ya guys for diy'ing the job.

wingedfish, no problem a $1000 for labour and probably would have agreed to $2500 a unit with installation, to cover markup on the unit and other materials. Just couldn't do $4000.

bkelly, again the insulation shouldn't be wet. No expert but I'd replace.

Not only does it remove the humidity, it actually does recover the heat.

Inserted a temp probe in the ducts a couple of feet from the unit (house side) exhaust 22°, fresh air 13° with the outside air measuring -9°C.

Are you're meaning condensation in the insulation? If the inner and outer lining are intact and sealed on both ends you shouldn't get any.

I tried not to have any low point (dips) in my fresh air run and the inlet on the outside wall is higher than the port on the HRV.

yes it was like a bag of water in the plastic sock that contains the insulation, ill try sealing the insulation at both ends , ill post some photos of my set up prob tomorrow. i also installed myself.
BTW:
I saw some pressure balancers on ebay when i was looking way cheeper . I never balanced as its an older house , i opened the baffles full .

Yep, mine was like that on my old HRV installation. The after the fact fix was to change out the insulation and really make sure the new stuff was taped off well from the in house air. Also, your HRV will probably have a feature that switches to inside air when the unit begins to freeze up from bringing in too much cold fresh air.
