It's the same problem as those portable AC units: the exhaust (chimney in this case) draws large amounts of air in from outside which is at the wrong temperature (cold in this case).

At some point they realised and the newer ones have a dupex air duct so you can keep air pressure even

Huh, just like a balanced flue.

You're talking about the best of what's available but that is rarely what builders use and retrofitting your already constructed house to use these could end up costing you 1/3 or more of your home's original value. All that is to say that builders cheap out on new home construction so most people don't get to enjoy the benefits if these innovations.

Um, nobody builds a house without modern insulation (rock wool etc) and 3-pane windows. It wouldn't be legal either.

Build, no. But here in New England (Boston suburbs) even double-pane windows are still quite rare, because most houses are ~100 years old or more.

Windows have a lifetime of only 15-30 years, though. If you have to replace them anyway, you might as well get double-pane (even if the rest of the house isn't well insulated).

The castles and mansions were relatively modern. Most people didn't have "good" home design, they had older, practical architecture. Their homes had thin walls, were drafty, and had no chimneys; there was a hole in the roof where the smoke from your fire would go, so your attic was filled with smoke (where you'd smoke meats for winter). You're better served by looking to 19th century lower and middle class architectu…

The 19th century was basically the low point of Dutch civilization. People stayed warm because 10 people slept in one room.

It was so bad that even rich people had to admit that the country had become an embarrassment.

What does 'lifetime' mean? Mine are nearly all original.

When we lost power for 10 days a few winters back we attempted to use the fire place for heat. It was a fail. Post and beam house (large wide open floor plan) with a large transfer from 1st to 2nd floor, and apprently my lack of skill for optimizing heat over beauty in the fireplace, left us without much of a thermal bump. To this day I swear we were pulling heat out of the chimney faster than we were heating the hou…

That’s not uncommon, but having grown up in a house heated by wood fires I knew that when building our current house. The main fireplace is on a central wall and has enormous thermal mass. Beauty and utility can be combined.

My grandparents' house was this way - the chimney was in the center of the house (built sometime in the late 1800s and rebuilt in the 1950s).

The fireplace had a stone chimney - and the kitchen was built in an 'L' shape around the first floor of the fireplace. The (master) bedroom (an additional bedroom was built in the 1950s), the stone of the chimney was a good quarter of one of the walls.

I do, however, think that the rough hewn stone and mortar of the chimney with the insets around it had a certain rustic beauty... aside from the "that got warm" in the winter and could keep the kitchen, living room, and bedroom warm.

Modern insulation with hvac is better yet. You need hvac to bring air in as a modern house should be air tight. Not much heat or ac should be needed.

To use it effectively you want one with water jacket and just use that hot water with your normal house heating system. You don't need much power to run circulation pump so UPS + some solar panels should be enough even in deep winter. There are also systems that get it out of the exhaust but that doesn't get you much heat storage, just instant heat and generally less efficient. Old school version of that were masonry…

This isn't a good idea because the water cools the fire too fast and you tend to get soot build up inside.

Yeah fireplaces don’t make sense to me. Hot air rises and it sucks the existing heated air in the house which all flows out. The only way to heat the space is you need something with a lot of thermal mass that heats up in the process and then radiates heat. So a lot of bricks around the fire, some sort of baffle to enable the heat transfer and a system that sucks in air from the outside.

I like the idea of an outside vent, and unfortunately, I think an insert of some kind. I can't help but first think of the goofy look of a wood fired stove sitting half in and half out of the fireplace. Surrounded by a few tons of river rock. That said, after a couple days of a couple degrees, it's either that or the tent in the basement.

The problem with outside vents is sometimes smoke goes out them - air comes down the chimney.
