Can HRV be connected to forced air ductwork?

When an HRV is connected to forced air ductwork, of course there are benefits. The mechanical ventilation system introduces fresh air to the house, and the heat exchanger recovers some heat from the exhaust air stream. Most HRV manufacturers can provide recommendations on the best way to hook up an HRV to forced air ductwork if you want to do this.

What is an HRV box?

An HRV is simply a box with two fans and some kind of exchange core designed for balanced inflow and outflow of air, with some degree of heat recovery. Its the installation and the duct system which determines where exhaust and return air ports are located and how much air flow each port will achieve.

How does an HRV system work?

All HRVs direct a supply of fresh, outdoor air into your house while exhausting stale indoor air outside. This dual-flow system is the ventilation part of the equation. An HRV also reclaims most of the heat from stale air before shooting it outside.

How to connect HRV to Furnace Fan?

if it closes when hrv is on, opens when hrv is off you can run an 18/2 wire to the HRV and connect it to those terminals. At furnace connect to R and G on the board. Hopefully thats all you need and other terminals dont need to be connected. it should turn on furnace fan with demand for ventilation, not other way around.

How do I install an HRV system?

With a simplified HRV install you will need to have it interlocked with the furnace fan. The Dehumidistat will allow you to select your desired humidity and then bring on the HRV and furnace fan to accomplish this.

Should I replace my furnace’s HRV?

A: I’d definitely keep the HRV. If your old furnace used to get its combustion air from inside the house (and it probably did), you’ll need the HRV more than ever. That’s because a furnace that draws combustion air from inside a house automatically causes fresh air to be drawn into the building from other places.

What is HRV and how does it work?

How does a HRV system work? Installing a heat recovery ventilation (HRV) system in your home improves the air quality of your home and saves you money. Put simply a heat recovery ventilation system does what its name implies – brings fresh air into your home while recovering a significant amount of the heat being displaced.

What happens when air passes through the HRV?

As this air passes through the HRV it warms the plates of the heat exchanger core. Clean, fresh, outdoor air is supplied to the house. As this air passes through the HRV it is warmed by the heat stored in the plates of the heat exchanger core.

Does HRV work on non air conditioners?

SUMMER – Non Air Conditioned Homes The HRV can only reduce the relative humidity of outdoor air (that is being supplied into the home) when the outdoor air is colder than the inside air.   If the indoor air is warmer than the outdoor air, the HRV is still an effective controlled ventilation system.

What happens to the HRV in the winter?

In the winter, the warm indoor air passes through the HRV core as it’s being exhausted and warms up the incoming fresh outside air. In the summer, the cycle is reversed and the cool indoor air cools down the hot outdoor air recovering the energy.
