An HRV is NOT a humidity controller. It simply exchanges enthalpy between air being drawn from the home and air that's being infiltrated into the home. Normally the ERV is run on a time schedule scheme that is established by first establishing the natural leak rate of the home and then calculating how much forced air ventilation needs to be introduced to get the home to the proper exchange rate.
As far as combustion appliances are concerned, each one needs to have sufficient air to provide for good combustion. Many products today can meet Category IV venting requirements and therefore have their own combustion air source as connected to the great outdoors. This requires 2-pipes from the appliance to the outdoors, one for exhaust and one for intake. The room air blower on a furnace does require air but that air enters the blower from the returns in the treated envelope, runs through the heat exchanger without mixing with combustion air and thence onto the treated spaces of the home.
If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!
