As timun say, yes. Probably a bit more costly having them run to the floor but so worth it. Ceiling vents in a basement are common as it's easy just to tie into the existing duct work but getting them to the floor will make your basement temperature much more consistent and comfortable.
Cold air return in the ceiling is going to do nothing but pick up air that has already been warmed. Get them down on the floor where they will do the most good. Proper air circulation is most important in in the basement IMO.

What are people doing these days for subfloor in basement? The dimply stuff coupled with rigid foam?

The HVAC guys I have in to put in a new furnace for the basement for a legal suite says they've changed their views on that lately, they now put the heat vents higher (above windows is where they're putting them in our basement).
His reasoning is if the vents are at the floor the warmer air is just going to rise anyway, so the benefit isn't that great, while bringing the ducts down to the floors is extra work and more importantly he said the more corners there are in a duct the harder it is for air to move through. So he said overall the slight benefit of bringing the heating vents down to the floor isn't worth it in his opinion.
Maybe this is a holy war in HVAC circles. Playstation vs Xbox. Tabs vs spaces. Coke vs Pepsi. Floor vents vs ceiling vents.

You can get Dricore with rigid insulation integrated now. It's called Dricore R+.

Sounds like more work for them = faint reasoning to not do it.
The heat entering the room at the floor level and then rising is what causes convection and more even temperature throughout the room.

I have dricore in mine and it helps a lot, without it I think it would be much cooler in the fall/winter. It creates a bit of a gap when going from the furnace room (no subfloor) to the hall (subfloor) but still totally worth it

I was thinking rolling out a product like this:
https://www.homedepot.ca/product/dmx...3953?rrec=true
Then laying 1" think rigid foam with R value of 5
https://www.homedepot.ca/product/dur...1234?rrec=true
Then the plywood.
I suppose now I'm adding 2" of subfloor before I even lay the actual floor. Hmm.
I might do the cost calculation later to see whats more economical vs R-value.

At what point would just installing underfloor heat mats be the way to go? Or even a trenched in underfloor heating system to your existing concrete? You'd be losing like 3 or 4 inches of space in your basement with all that stuff. And wouldn't the dricor make the roll out moisture barrier irrelevant? Also I think your choice of flooring material would make a difference. I'm not sure I'd want to install tile over all those subfloors. Maybe over the 2" dricor but I'd feel like a decoupling membrane on top would be safer still. But then you'd just have cold tile. All this depends on your choice of flooring.

You could do that and it would likely be much cheaper than dricore. When I had the basement done they tried to talk me out of dricore saying it was really only useful if you have moisture issues (I don't). I disagree - the insulation from the cold concrete is worth it. It was installed with carpet....the other thing to mention is it has 9' ceilings so space wasn't an issue but in some basements it would be

Still very much just in planning stages. But the rolled out moisture barrier/rigid foam/plywood subfloor would be instead of dricore. I figure it's higher R-value and likely cheaper. I would then do carpet with traditional underlayment. My guess is I lose 2" of height pre-carpet.

I'm not sure but I think fastening the plywood on top of the rigid foam on top of the moisture barrier would be a nightmare...like 3 inch tapcons through everything into the concrete thus sort of nullifying the vapour barrier and permanently numbing your arm from hammer drilling. I think dricore is the way to go. People have done rigid foam and dricore. But you can also get carpet underlayment with vapour barrier and enhanced thermal break. I might go that route.

Temperature, foot feel, sound were all amazingly better - felt just like a main floor really.

I've done the many screws through XPS and plywood and it was not too bad. Worked with one other, one person pre-drilling spots and the other following with tapcons. Floor felt warm and solid after.
You will get (slightly) better but essentially the same R-value (3+) with 1/2" XPS, dimple roll and plywood than you get from the Dricore, and I have to think installing large sheets will create a better floor than a bunch of 2x2 squares. Fair point about the screws reducing R value, not sure how significant that would be.
I have never installed Dricore but it looks easy, considering the same options for my own basment finishing.

I can't get on HD site right now but I'm pretty sure I know what you're propossing. I built a basement suite a few years back and the homeowner installed the flooring the way you are looking at, minus the insulation. The subfloor being gapped from the concrete by the dimpled plastic is pretty good at keeping the floor from being too cold. They put laminate on top. Saved some money over dricore and got the same effect. The only thing with layering materials yourself is there is no bond between them and you can gets some squeeks and sponginess in any spots where the concrete has uneveness.

I’m finally getting work done to replace damaged exterior from the June hailstorm.
So glad to get rid of the creamy pink vinyl siding.

Are you getting vinyl siding again, or going with something more durable? I'm a big fan of LP SmartSide. I put it on my garage, and will be doing my house with it next year. Hail wouldn't make a dent in it.
