That's because it's old. Old houses leaked warm, humid air out all over the place. New houses are sealed so fucking tight, they literally have to create controlled leaks (that's what the HRV does) so that your windows aren't permanently fogged up by your fart gas and shower steam.This quote is hidden because you are ignoring this member.

The theme of the thread is how TréSlow is supposed to increase his humidity because his house doesn't have all this hyper efficient crap. Meanwhile, a bunch of us practically need two dehumidifiers plus our HRV running just to stop our allegedly super efficient, sex-paned mega windows from fogging up.
Tight houses introduce a significant new batch of things to deal with that are very foreign to homeowners. But, they do cut heating costs. My house is literally double the area of my old one and it costs half as much to heat. For serious. It's pretty amazing, but these frosty windows are a pain in the urethra.
Can someone tell me if this is my HRV unit? Looks like it actually might be connected to my humidifier.
I ran my ventilation fan for several hours yesterday (with humidifier set to "summer" and thermostat set to minimum 15%) and did get about a 10% drop in humidity on the main floor, but nothing upstairs. No changes in my windows unfortunately.
That definitely looks like an HRV to me.
^ Yes that's your HRV
Sweet, thanks guys.

It is usually not controlled from a bathroom fan or anything of the sort. If you turn the humidity dial way up, it will trigger your humidifier to flow water and the air going through that will jack up your humidity. If you turn it way down, your HRV will come on bringing in dry air from outside and blowing out the wet air that you paid to heat and scavenging some of its heart on the way out.

I have a switched labelled "Ventilation" and it turns on the main floor bathroom fan, as well as the furnace (just the fan though I think?). It blows a mixture of warm and cool air, so I imagine the furnace kicks in when needed, but the fan runs 100% of the time that I have the switch enabled. I don't know if using the Ventilation fan is using my HRV or not, I thought it did but maybe not.
My lifebreath doesn't have a control panel that I can see. I think it is permanently on unless I close off the ducts manually.

Ran our HRV all last evening and got the humidity from 35% down to 31% but it wouldn't go any lower. And its back up to 34% this morning. Triple pane windows have a small amount of ice on the sill and mullions.
Unlikely. I have a similar setup. If you can turn it off and then you go stand right under the HRV when someone flips it back on, you should be able to tell. The HRV likely has its own pair of small fans that you'll hear kick in when it actually comes on aside from your furnace fan merely coming on (without heat).This quote is hidden because you are ignoring this member.

The problem with low humidity is that the hardwood floors might crack.

Down to 15% meow. I really need to hook that damn thing back up when it gets warmer out.
This gets said all the time but I have 65 year old hardwood and no cracks yet. Bought the house off a slumlord and the humidifier at that time was easily busted for decades.This quote is hidden because you are ignoring this member. Show Quote
As you guys dick around with HRV this and that, I'll just enjoy all your hassle and repair stories.
Some homes don't have a stand alone bathroom fan anymore. The bathroom fan switch is directly hooked up to the HRV and will put the HRV into max vent mode for x amount of time.This quote is hidden because you are ignoring this member. Show Quote
Do you have a controller somewhere beside your thermostat for the HRV?This quote is hidden because you are ignoring this member. Show Quote

Sitting at 15% also. Fuck, some of my neighbors windows are literally covered top to bottom in moisture on the inside. Idiots.
Unrelated to humidity (at the moment), but I've suddenly just realized I forgot to turn off the one of my outside taps, or drain the line.
When my lifebreath kicks in, you can hear it when you are in the furnace room. It's a distinctive sound.
I think that if you didn't "upgrade" your HRV, it is likely passive and linked to the Vent switch and the furnace. I have direct control of the my HRV with timers in all the bathrooms as well as a central control mounted on the wall below my thermostat.
