HRV revisit

WingedFish, normally how much do you charge for just installation? It seems like in Calgary, installer charge roughly 1K


I am not sure about all the CFM stuff but i guess LifeBreath RNC 10 should do the job because it is s little bit bigger than RNC155. also it has defrost port which i don't know if it is that useful.

Depends on the job, some are quick with a mechanical room on an outside wall and don't need it pretty. Some are not.

The defrost is needed for when your moist humid stale air freezes to the heat exchanger. this will block the air exchange in cold weather, the real time to need it. For a reefer, a defrost mechanism is a must.

May I suggest a venmar eko 1.5 HRV. It's a compact unit that uses variable speed dc blowers and can be setup for many different homes. Because the blowers are variable speed the system can make up for difincies in your ductwork and makes retrofitting it into old duct system easy. There are 3 settings that can be used to size the hrv for your needs up to a maximium of 153 cfm. Because the blowers react to static pressure in the duct work to make sure they deliver the cfm they are set for you can use a smaller unit and be confident that you are actually getting the air exchange required. here's a link to the info page.... http://www.venmar.ca/AfficherProduit...ngue=en&id=124 . Another plus is it's extremely energy efficient compared to a standard model . I have serviced most major brands of air exchangers and that`s the one I recommend most to my customers for its ease of install, low operating costs, and its ability to accommodate many different homes.

Just had one put in my house by a hvac neighbor. Have a 450 gallon tank and he was very concious about things like where to put in the intake, where to put the humidistat to make it more efficient, etc. Installed it for a hell of a deal and I will be having him install them for all of my customers tanks that require them now. Pm me if you want his number and make sure you tell him Nate sent you and you are likely to get a pretty sweet deal.
