MY HRV feeds directly into the furnace. I have no duct heater and it is not needed at all.
Some "mechanical" contractors say you need one, or else humidity will be a problem in the HRV unit. That is wrong on most new HRV units. They will work for many years w/o. They are just trying to sell you something IMO. I would only run it when it is around -25 or colder.
