Do pellet stoves generate much creosote?

Having lived in a house with wood heat for over 40 years, I've fairly familiar with the ways in which wood stoves can contribute to creosote formation in chimneys and stovepipes. However, I'm not very familiar with pellet stoves.

A friend recently wondered about creosote formation in a chimney connected to a pellet stove. So I'd like to hear from owners of pellet stoves: Does your stove lead to more or less creosote formation than a typical wood stove?

Location of Multi Port Tee for Plumbing

Hello GBA, Zone 2A, I'm replumbing my house, and need help deciding the location of the main multiport tees. There will be 12 lines for the cold, and 8 for the hot. I can put it in the garage right by the water filters and heater, then route all lines up and over, or just put the tee in the attic then route the lines over from it. There is an access panel immediately in front of where it would be in the attic, so access is not an issue. All lines before the multiport tees are copper.

Pros of the in the attic:
Easier routing.
Looks much cleaner in the garage.
Less PEX used.

Where to vent the dryer and range hood exhaust?

I am building a house with the dryer and the range located in places where it would be difficult to vent them anywhere other than through the roof or through the vented soffit at the eaves of the house. (It's about a 40 foot run to get to the gable end)

I understand that venting an appliance through vented soffit means that the humid air will likely get sucked up into the attic where you don't want it. However, reducing roof penetrations appeals to me and I am concerned about lint build-up being harder to deal with if the dryer is venting through the roof.

Humidity

While I was on the subject originally regarding adding central air to my gas furnace, someone was talking about humidity levels in the winter and how dry you feel at home.
I just realized and was told that whole house humidifiers only work/operate anyway, when the furnace is actually running. Makes sense.
in my opinion, and having a hydrometer to prove it, whole house humidifiers are a waste of money, period.

Noise from PEX/PVC drain pipes

Hello,
We are at the stage of starting the framing for the new construction home in Pittsburgh. It is also a Passive House duplex. Our architect specified cast iron for domestic water drainage pipes (from shower and toilet, etc.), mostly on the account that these result in most quiet interior. For delivery of the water within the house, PEX is planned. Then we heard that iron pipes are more susceptible to clogging. Is some compromise, where pipes close to dining/living room are cast iron, and PEX elsewhere an OK option?

I have a slab-on-grade floor (pre-1900) that sweats enough to where it can get slippery in summer

What can I do to prevent this?

The building is a raised "shotgun" in New Orleans. The lower area (about 7.5 ft. tall ) has been converted to an apartment. This is quite common here. Originally, these areas were used for storage only due to the possibility of flooding.

It is basically an unconditioned space, the hvac provided by window units.
The walls are insulated with Rolux batts, no ceiling insulation, and the old single pane double hung windows are fairly tight.
Is there an elastomeric, or epoxy type product that I can use to mitigate some of this problem?

Radon fan location: outside via drain tile?

Per the oft cited recommendation, we installed a passive radon pipe in our home during construction. It's piped off the foundation Form-A-Drain and incorporates a top of the house area with electrical circuit and enclosure for the radon fan. We are now at the point where it probably makes sense to install that fan. In fact the fan is here ready to be plumbed in. (I have good reason to believe the passive radon pipe vent works, at least to some degree; certain times of the year you can see frozen water vapor near its output.)

Question on ballpark renovation costs

I know it varies and there are a lot of variables, however.....
Anyone give me a ballpark cost to totally gut my 1 1/2 story , 2 bedroom cape cod style house? Everyroom except the only bathroom, upstairs?

Questions about furnace air returns

Regarding furnace air returns.
Questions:
1. Can I get central air installed, have a gas forced air furnace?
2. Would I benefit from fresher air in the home if I had an air exchanger installed?

House built 1920, had coal furnace, converted to gas, had the big octopus in the basement with gravity heat.
Because of that only one duct upstairs in hallway,
None in 2 bedrooms, doors were kept open.
Only one return in living room floor.

Have had forced air furnace for 17 years, live in a electric municipality where electric rates are low, 20-30/month.
