Drill big fat holes in it of course!
We've entered my most dreaded phase of building.
It's utility time.
I despise this stage because there is so much work, so much money invested ... but you can't see it. In other words, you aren't getting a finished project. You are getting what looks like a freeway interchange of pipes to be hidden inside your walls. It's going to be a long few weeks of drilling holes in the interior walls of the Momplex and pushing pipes and vents through, and later pulling wires though.
Where to start? These are the systems we will have in the Momplex:
I know, these new houses are really getting complicated! But a little work now will sure be nice for Mom later on!
So where to start?
Because everything has to run in the walls or floor joists, sharing the same space, starting with the biggest pipes makes the most sense.
And the HRV system has the biggest pipes at 6" in diameter.
An HRV system basically pulls stale or moist air out of the home, and as it goes out, it exchanges with the new air coming in, warming that new air up. So it's more controlled and efficient than cracking a window.
To make sure we had a balanced HRV system, that works optimally and keeps the air fresh, dry and warm, we worked with a local ventilation company that engineers the design and supplies the parts and oversees you DIYing the installation. By going the DIY route, we are getting the best possible system, but saving over $3000.
Are you wondering how we run a 6" pipe through a 2x4 wall?
Well, you squish the pipe of course!
But we will need to do double duty to squish the pipe to fit inside the 2x4 walls.
With all the holes we are drilling, we invested in a good hole saw kit. Yep, no more smoking (yes, smoking as in burning smoking) wood as you try to drill a 4" hole.
Here's a close up for you.
And then it's just take your pipe
And cut it to length.
And snap the pipe together. Of course every seam or joint of ever pipe gets taped to prevent air escaping and creating an inefficient system .. but that's another story ... and another day .. er few days.
Then the pipe gets put in between the joists.
Where the pipe runs between joists, parallel, blocking is placed in the joists to support the pipe.
There is pipe everywhere in the basement ceiling.
Grandpa Tim helped out, and although it seems like a ton of work, the HRV system was done in 3 days. Not bad for a $3000 savings!
I think we need to take Grandpa Tim on vacation!
And if I say so myself, even though I dread this stage and gripe that nothing gets "done", those are some pretty pipes!
We still have to hook the HRV system up to the piping. Can you see the green box? That's the boost button, guaranteed to suck moist air right out of bathrooms and prevent windows from icing up and mold developing.
It will be interesting to see how the system performs!
So what do you do in your area for ventilation? Do you just open windows? Or do you have an HRV system? Do you like it? Or never use it? It's interesting to see how other homes keep air fresh and dry without throwing good heat out the window!
