Makeup air advice needed
I had a recent post asking advice regarding HRV vs exhaust only ventilation for my very tight energy efficient smaller home that I am building. Balanced HRV systems if installed properly could have exhaust lines in the bathroom and in the kitchen with boost capacities negating the need for additional exhaust lines.
The major stumbling blocks are the very high cost of proper installation and space requirement for the system itself for easy accessibility as well as space for the duct work.
So I am back to considering 2 pair of Lunos h2 fans which provide HRV capabilities and are more affordable, I would then install an intermittent exhaust fan in the bathroom (150cfm) with a timer switch and a modest range fan (220cfm) in the kitchen.
My question is: What can I do to supply makeup air to allow these intermittent exhaust fans to do their intended job? I will have a single heat pump in the main living area. My home will be 1ach50 or below. Thanks.
