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…
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.

The times they are a-changing. Every house on my 21 year old estate came with ac. I'd assume the same for newer constructions. People rarely use it due to the price of electricity. Temps get well over 30C for a couple of weeks in august.

And make a bathroom practical and enjoyable. Sink with hot and cold tap, electric water heater in shower, come on...
I don't think I've ever been in a UK home that didn't have these, except perhaps the electric shower; older homes may still use immersion heating for hot water. Were you in prison when you experienced the above?

#74Or 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.
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.

Extremely doubtful. Even Teh Grauniad disagrees.

Note that the Grauniad figures include some very unusual heat waves. There's no way the normal average could be a lot higher in years that were a lot colder.

Yeah, if you actually want to heat the house with fire you’ll want an insert or a wood stove. Otherwise most fireplaces in most houses are decorative, and one pays for that decoration with heat loss.

It's not like the wisdom is lost , it's just ignored in modern builds. All architects think about siting and solar exposure. But the builders are in charge, and they optimize for what the market responds to -- which does not always include factors like these which contribute to long-term comfort and livability. So I would say that consumers could learn a thing or two. That said, most buyers are not buying newly-built…
Even when the buyer is buying a newly built house, it's often already built or being built off of already existing plans that do not take these things into account.

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.
There was a noticable (and well recorded) change in the climate for awhile when Ghenghis Khan went on his rampage. And he was a lot less effective at killing people than novel old world diseases. It doesn’t seem completely implausible.
Re: An Elizabethan mansion's secrets for staying warm
#80It's an interesting article on this one particular mansion, but the idea that "the same tricks for more efficient heating can be used in modern designs" seems pretty silly. We don't use fireplaces anymore (a major "trick" being to put them in the middle of the house rather than in the exterior walls), and while using large windows to capture sunlight and heat works great in the winter, it also leads to overheating in…

1.5' overhang is good, 2' is ideal. Cheap builders will go 1' or even less.
Good architects still pay attention to the sun. It's often builders who are the culprits because they want to save money.
