If so then your home might be creating too much moisture and condensation. The second method would be getting one of our trained specialist in moisture control to take a thorough analysis of your home.

Air exchanger are installed in most new homes today, they work with the existing HVAC system to ensure fresh air is coming into the home. At the core of the Air exchange there are small passage ways where the air gets warmed up with the stale air from inside the home. The stale air gets sent to the outside while the new air is sent to the inside. Refer to the picture below.

Every home is different depending on how much condensation builds up during the winter, Simple answer is yes. During the winter, your home will experience high amount of condensation due to the insulation and moisture barriers Thermo poly. You could try to get away with 5-inch, but this size might not allow sufficient air flow. Why take a chance? The rough internal surface of the insulated duct impedes air flow more than smooth duct does.

Plus, the polyethylene outer wrap on the insulate duct is fragile. It must never be torn or damaged. These two reasons are why you want as little insulated duct as possible in your installation.

Access to some kind of drain is another issue that affects HRV location. The amount of water produced by an HRV is relatively small, so you can connect the drain line to a sump hole in the basement floor, a regular plumbing drain, or even a floor drain.

You can tap into typical ABS drain pipe by drilling a hole for the flexible vinyl drain line from your unit, then use silicone caulking to secure the line within the pipe. Think the HRV location issue through and give yourself a day or two to consider several options before choosing a final spot. The least important location feature is access to electricity.

Adding a new outlet nearby is better than having long ducts or a long drain line. Sheet metal work usually forms the biggest part of most HRV installations. Duct needs to be cut flat. This allows lengths of assembled duct to be connected end-to-end — one piece fitting inside the other. But it only takes one short cut to remove the crimped end from a length of pipe. Then what do you do next time when you need another crimped chunk of pipe to make a connection? Instead, crimp it yourself, one fold at a time, using needle nose pliers.

It only takes a minute or two and does a great job. When it comes to joining pipe, choose self-drilling, hex-head screws torqued in with a cordless drill. Why use fasteners that require a pre-drilled pilot hole when the right screws do the job themselves? All this said, even worming your way through wood and siding can be tricky. As you size up the job, remember these four steps: trace, trim, drill and saw.

Start on the inside of the basement by drilling a single hole through to the outside, right in the middle of the hole required for the duct. Move outdoors, then trace a circle around this hole. If horizontal siding is involved, tweak the up-and-down position of the louver a bit so its top edge lines up with a natural joint between siding members.
