Even a cheap thirty year old furnace can do that - it was able to keep my house at 80° during the -40 (no need to specify; they’re the same that low!) last year. I actually intentionally drove it to 80 to give me thermal mass if needed but it turned out not to be necessary.

Burning gas is insanely thermodynamically active.

As an addendum, this winter I unfortunately found out that, at very low temperatures, the limiting factor might be the furnace, but it might also be the capacity of the radiators (or underfloor heating, or whatever) to shed heat. Tiny radiators or highly spaced underfloor pipes and it won't matter how fancy your furnace is, there's only so much heat it can distribute.

Radiators are an alternative to, not a part of, a forced air gas furnace.

Gas furnace burns gas, blows around hot air.

Radiator heats water, and pushes that water around to heat rooms via radiators.
