Maxwell: HRV eases air pressure problems
How can I balance the air pressure in my house? At 7 a.m. there
can be as many as five fans pumping air outside – the furnace,
gas-fired hot water heater, two bathroom fans and a kitchen exhaust
hood. Surely this creates negative pressure that would wreak havoc with
the heat recovery ventilator (HRV) I'm planning to install.
