My furnace is probably going to run most of the day will have a fire soon

That's kinda 1 good thing about being center unit town home. House retains heat somewhat well so furnace doesnt run all the time.

yeah at work we are an end unit and own the unit next to us also, and the heat is rarely on over there, and our main office is freezing always.

Goddamn, my main furnace ran 7 hours yesterday and upstairs furnace 3.75 hours

OK how does this compare to mine.

DEEZUZ furnace is sized correctly for the house. Design temp in our area is 0*. Meaning, at 0* the furnace should perfectly match the load running 100% of the time.

N20GT stuff is mega oversized, short cycling and wasting energy.


I’d bet 90% of equipment or better is oversized. Granted most equipment capacity is in 20k BTU jumps for furnaces. Two stage or modulating equipment is the way to go. It matches the load much better and will provide better comfort because it stays running near continuously and gets rid of cold/hot spots.

So I'm good?

Interesting, so it's considered normal for a furnace to run basically 100% of the time on cold days, and that doesn't affect longevity?

Hearing this makes me feel a little better that my furnace is basically off 8 hours/day while we're at work, so when it kicks back on, it runs for a while to get the temps from low 60's up to 68.

lowering temps when you leave

 

[DEEZUZ]

I mean yes there will be increased wear.

 

[DEEZUZ]

Yea I don't like the idea of dropping the house low.

Keep in mind everything in the house is that temp too. Now you gotta re warm up all your stuff. Weird.

 

[FirstWorldProblems]

I'm also not heating the basement basically at all right now because it's not finished and we're never down there, so the main furnace is def way underutilized

now your couch has to go from 60 to 68

and your floors

and your counters

etc etc etc

Yes. At design temperature for your area, if your equipment is sized correctly, it should run non stop. Applies to cooling too.

You can look up the info here:

what if my AC runs non stop in the summer and doesn't keep up?

 

[FirstWorldProblems]

Yeah it's insulated and the side with all the windows faces SE (no wind), so it stays around 60* without the furnace ever really running

Get more insulation in the attic and air sealing. There’s good rebates on it and it’s basically the same price for a pro to do it vs DIY at that point

Like I said I have one double bay window/wall that's fucking stone cold and I can feel a draft. I'll probably have to tear the drywall out to insulate it?

i have an actual fuck ton in my attic. 18"+ in most areas.

air sealing i need to find someone reputable- any ideas?

my issue is front bedroom has 3 exterior walls and faces south east. it's just fucked by the sun as also no shade whatsoever.

Caulk the trim to the wall so there’s no air gaps. You’re probably feeling radiant cooling mostly from all that glass.

Is the underside of the bay that protrudes out of the house built out to the ground or is it just a cantilever with bare plywood underneath?
