ERV/HRV Question
« on: December 15, 2014, 10:32:53 AM »
Almost set to move into a new house.  Forced air heat with a plenum for the wood boiler water.  Have an HRV that works by kicking on the furnace blower to circulate the fresh air once it's exchanged.  Since the circulating pump runs 24/7, it'll blow heat from the boiler along with the new air.  Anyone have issues with having too much heat with an HRV?  My hvac guy is wondering about it, and will be showing me how to turn off the HRV if necessary.  Since I didn't see anything on here about it, I'm guessing it's not much of an issue.

I'm just wondering why he has it so your blower kicks on, if you don't have zone valves installed and your air exchanger kicks your furnace blower on you will most Definatly be heating your house.

An HRV also does not need to be piped into the ductwork, generally that's how its done but it doesn't have to be

I just had a heatmor response installed and I also have an hrv unit that uses the furnace fan. I didn't think of it before hand but it does generate a lot of unwanted heat if the hrv us set to a low humidity level.
