When we first viewed the c. 1827 home that we would ultimately purchase, we were thrilled with the four fireplaces. The home had once been a double dwelling house for the workers at the Boston and Sandwich Glass Company. Each side of the house has a kitchen fireplace, with a beehive oven, and a parlor fireplace. And each fireplace has the tell tale angled walls of a Rumford style fireplace.

In 1798 and 1799, Count Rumford wrote a series of 3 essays describing the ills of the common form of construction of a fireplace and the remedy to save fuel and increase comfort:
Chimney Fireplaces, with proposals for improving them to save fuel; to render dwelling houses more comfortable, and salubrious, and effectually to prevent chimneys from smoking.

According to Monticello.org, Thomas Jefferson's Monticello has 8 Rumford style fireplaces.
Jefferson wrote to his friend, Wilson Cary Nicholas regarding the dimensions of his Rumford fireplaces:
Mr. P. Carr informed me two days ago that you wished for the dimensions of the Rumford fireplaces. I therefore avail myself of the first post to send them. I state them as I have used them myself, with great satisfaction, the back one half of the opening. Count Rumford makes the back but one third of the opening, this was to accommodate them to coal; but it renders them impracticable for wood. My larger fireplaces I make 2 f in the back & 4 f in front; those for bed-rooms 19 1/2 i in back & 3 f - 3 i in front. The opening of the former 3 f - 3 i or 3 f - 6 i high, the latter 3 f high.

Which brings me back to my fireplaces - none of which are currently working. We are having them parged inside and re-pointed where needed. Our mason tells us that the fireplaces have great draw - Yay Rumford!
