Wow lots of great info and opinions on HRV/s Here's mine...
We have to keep in mind that a HRV is an AIR EXCHANGER and not only a De-humidifier.
The De-humidification is an added bonus this unit features, or provides.
It is quit amazing how much OXYGEN is reduced in the home and not replaced. You probably dont notice it but you are probably getting tired and sleepy. Your Furnace uses oxygen as it burns, your water tank uses oxygen when it's running, each person in the house is using oxygen, and MOST IMPORTNTLY our aquarium's are using it all up. I guaranty you will have more stable PH if you install a Air Exchanger, usually will go up by .2 or .3.
I realize some homes have fresh air and combustion air intakes to the furnace room but this does not provide air exchange, but prevents a negative pressure in the house.
Personal y I think An HRV is a Very important unit in the climate that we live in. < if installed properly> Not only as De-humidification help but for Healthy Fresh outdoor air.
AS mentioned above aswell make sure that your humidifier on the furnace is installed correctly, especially if it;s a new home. < iv been to too many home's where the humidifier was installed incorrectly and runs anytime the furnace comes on >
The money we put into this hobby... , $700 unit is nothing in the long run, and will save your home from mold.
