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.

*outside intake. The vent would just be the chimney.

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…

the fresh air inlet should be piped along the chimney walls, this would also recover the condensation heat of the water produced during combustion, but its not trivial to design while keeping in mind things like maintenance, different chimney column temperature (and thus different convective forces), capturing and effluence of the condensed water, ... the heated fresh air should not directly go to the fire but piped into the room.

Related to the Maunder Minimum, named after my namesakes: Astronomer Walter Maunder and his wife Annie Maunder. https://en.wikipedia.org/wiki/Maunder_Minimum And here's more info on The Little Ice Age: https://en.wikipedia.org/wiki/Little_Ice_Age Debatable as to whether solar activity was a contributor to The Little Ice Age.

What did you think about the point in the article suggesting millions of people dying on South America caused the earth to cool down due to reforestation absorbing more green house gas. I find this hard to believe.

What a strange question.

> For example, how many houses have a cupola? They're common on older homes, but non-existent on modern ones. What the roof does is accelerate the wind moving over the roof, then the air vents in the cupola let the wind through, which sucks the heat out of the attic. This one is genuinely obsolete. With modern techniques, it’s straightforward to build a reliable unvented attic, and there are few if any climates where…

I've been in an attic many times on a sunny day. The heat in the attic is well above what it is outside. I'm highly skeptical that an unvented attic is going to keep a house cool in summer.

Well that's full of really useful tips. I'll get the builders in to construct a 1.37m (4.5ft) thick spine through the middle of my house. Obviously.

You're missing out if you don't have such thick mass of warm brick/stone. If you only knew how great it is to sleep on top of it (my grandmother had similar to that in her house :)

https://en.wikipedia.org/wiki/Russian_stove

Modern fire codes require large space between a stove and walls which is usually goes unused where it could have been really filled with such a thick brick structure with the smoke passage snaking through it like in Russian and German stoves. Or like this:

Or go solar with a battery, or just have a massive battery hooked into your distribution panel and leave the 19th century heating hacks in the 19th century. Optimize what you need for today, not whatever was state of the art 200 years ago. An electric space heater running continuously is enough in an emergency.

Brits will do anything except properly insulate their damn homes.

Brits, Dutch, Belgium, Northern Germany. They all have this incredibly outdated building style that they refuse to change. Bricks with no insulation. I live 1000km to the south of them and it is pretty standard for us to have tripple pane windows and thick insulation on our houses. But they for some reason prefer to live in cold houses during the winter and overheated houses during the summer. I have had multiple con…

Purely anecdotal, but every house I have ever visited in the Netherlands and Scandinavia has been properly heated and above all insulated. Which is absolutely not the case for the UK and even less so for France and countries further "south". If you want to be cold indoors in Europe, spend a winter in Spain, Portugal, Italy or Greece. Here I speak with some experience.

> The house has lessons for how we can heat our homes more efficiently today The problem in Europe isn't keeping warm in the winter but keeping cool in the summer. In part thanks to their near-total lack of AC in residential buildings, Europe has an extremely high heat-related death rate. 200k people per year die of heatstroke in Europe: this accounts for 36% of global heat-related deaths. This is despite Europe bein…

My local HVAC guy joked with me that the next Bezos/Musk billionaire type is going to be the guy who runs an HVAC company in Europe.

I don't think you understand how much power electric heaters use and how poorly solar converts to electric heat BTUs. A heat pump would be better.

An open fire is not a particularly warm thing to have unless you’re directly in front of it. Most of the heat goes straight up the flue, and it uses an enormous amount of air to keep burning - it will pull huge volumes from rvertwhere it can. This is why these old buildings didn’t suffer from damp issues - the open fires burning were ventilating them.

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).
