Super-insulated houses do have counter-current heat exchangers to let the out-going air warm the in-coming air. Enough counter-current stages leaves the out-going air very little warmer than the incoming air.
The out-going air does dump some water vapour as condensation on the membrane separating it from the incoming air. You want to arrange that to drain somewhere where you don't get to smell it.

Here, in the far North (60 to 70 degrees N), we have another heater for the cabin, connected together with the block heater.
There are similar systems running on car fuel, the most common brand is Swedish Webasto.

Oh, I've got a hydraulic wood splitter. (Once you've used hydraulics, you are ruined for life.) (My house came with a backhoe too.)

dOh yeah I hate when it's starting up, or needs to be poked. (poor air flow... It's forced air, with a fan that turns on when the thermostat gets to low.) It belches smoke. I'll turn it off if we are having a party or outdoor thing in the summer.
I think clean burning is a great idea in theory. In practice, my limited experience is that it would be a lot more work/ maintenance to keep it clean and efficient. You are fighting against creosote build up on one end, and all the ash on the other. It's easier to just cut up a few more logs to feed it. (I know perhaps not a "green" attitude.)

We were staying at relatives during Xmas. Their thermostat was set higher than at our house, but I noticed I was never as comfortable if I was just s itting around. My theory was that it was the older draftier house.. Kind o f an indoor wind chill factor.

Heat pumps use "hot gas defrost"- look it up. The only electric heaters are in the compressor crankcase to prevent the accumulation of liquid refrigerant there, which can have disastrous and catastrophic consequences under some conditions. The indoor backup electric heater will /sometimes/ activate during or shortly after the defrost cycle. No question the overall efficiency declines as outdoor temperature drops, and this is more due to the increasing temperature differential between the coils than the defrosting requirement. Air exchange heat pump technology is garbage compared to other forms, something else that needs to be regulated but won't be.
No you won't:-)
Well the garage is attached to the house and a bit like a basement too. Shop, water service, storage of paints/ liquids/ metal tools...etc. Dog doors to outside, Cat liter box in the winter.
I keep it at ~45-50F. But it's also great to be able to crank up the heat when I have a week end shop project, or car vehicle work.

Wow, do you live in Sweden? Near the arctic circle? (And I thought missing the sun here in the winter was hard.)

Any imbecile can install one of these:
Why don't you try reading the book before you read it to others:
Mold is a different issue altogether, and its formation is completely elimi nated in a multitude of different ways.
I will not pretend to know everything, but never heard of building material s emitting radon. Radon gas comes up through the soil under the foundation and gets trapped in an airtight structure without ventilation.There are sys tems of ventilating the subsurface to prevent this and it's not expensive.

Re: Radon anything made with granite or other stone could have some Uranium in it and emit Radon.
Fun fact. It was pointed out to me the other day that Radon has a four day half life. I had this (mistaken) idea that Radon came from deep u nderground... But it has to be a source much closer to the surface.. Else it will decay before it gets into my basement.

No - Finland, but nearly the same northward.

The coldest I measured at 7pm and around midnight were 3 to 4 F. Not sure where the nonsense -600 temps the weather places came up were fabricated.

But that depends on the dew point of the outside air, and on the heat pump's duty cycle.

Ours reverse occasionally to blow the ice off the coils. Makes a strange noise when it happens. ;-)
The efficiency is pretty low at -5C. Mine start using the resistors at 40F (though the pump is still used).
Have you thought about a ground water heat exchanger? It saves money in the summer too.
