The Comfort of Masonry Heat Storage Fireplaces
All day long all parts of the room will be delightfully warm and comfortable, and there will be no headaches and no sense of closeness or oppression.  In an American room, whether heated by steam, hot water, or open fires, the neighborhood of the register or fireplace is the warmest--the heat is not equally diffused throughout the room; but in a German room one is as comfortable in one part of it as another.  Nothing is gained or lost by being near the stove.  Its surface is not hot; you can put your hand on it anywhere and not get burnt.

Consider these things. One firing is enough for the day; the cost is next to nothing; the heat produced is the same all day, instead of too hot and too cold by turns; one may absorb himself in his business in peace; he does not need to feel any anxieties or solicitudes about his fire; his whole day is a realized dream of bodily comfort.

America could adopt this stove, but does America do it? No, she sticks placidly to her own fearful and wonderful inventions in the stove line. She has fifty kinds, and not a rational one in the lot.  The American woodstove, of whatsoever breed, it is a terror.  There can be no tranquillity of mind where it is.  It requires more attention than a baby.  It has to be fed every little while, it has to be watched all the time; and for all reward you are roasted half the time and frozen the other half.  It warms no part of the room but its own part; it breeds headaches and suffocation, and makes one's skin feel dry and feverish; and when the wood bill comes in you think you've been supporting a volcano.

We have in America many and many a breed of coal stoves, also--fiendish things, everyone of them. The base burner sort are heady and require but little attention; but none of them, of whatsoever kind, distributes its heat uniformly through the room, or keeps it at an unvarying temperature, or fails to take the life out of the atmosphere and leave it stuffy and smothery and stupefying...

The slowness of one section of the world about adopting the valuable ideas of another section of it is a curious thing and unaccountable.  This form of stupidity is confined to no community, to no nation; it is universal. The fact is the human race is not only slow about borrowing valuable ideas-- it sometimes persists in not borrowing them at all.

Take the German [any European heat storage masonry fireplace] stove, for instance...To the uninstructed stranger it promises nothing; but he will soon find that it is a masterly performer, for all that.  It has a little bit of a door which you couldn't get your head into--a door which seems foolishly out of proportion to the rest of the edifice; yet the door is right, for it is not necessary that bulky fuel shall enter it.  Small sized fuel is used, and marvelously little of that.  The door opens into a tiny cavern which would not hold more fuel than a baby could fetch in its arms. The process of firing is quick and simple. At half past seven on a cold morning the servant brings a small basketfull of slender pine sticks...lights them with a match and closes the door... the work is done.
