The well-known brass or copper warming pan on a handle was not the only way of warming the bed with embers from the fire. There were also wooden frames designed to hold pots of fuel inside the bedclothes.A warming pan, sometimes known as a bed warmer nowadays, was a valuable family possession handed down from generation to generation, but not so expensive that it was only for the rich. If you were very wealthy you might have a silver one, or a richly decorated copper warmer. Some of the most ornate warming pans have an elaborate pattern of perforations incorporated in the design.
But not all warming pans had pierced patterns. This difference would have been crucial for the servant or housewife using the pan. With air holes, the embers would keep smouldering, the heat would last longer, but the bed would probably smell of fumes and there was an increased risk of scorching the sheets. The smell was not always of wood or coal; in some parts of the UK it was burning peat.
In 1800's Britain fully enclosed warming pans were popular. Whilst they were cleaner, the heat would have died down more quickly. Some warming-pans with solid lids were used with hot water. Others were completely open like this un-lidded warming pan from the French Alps.Warming pans on a handle were designed for moving up and down the bed before someone got into it. The handle was not always lined up to make it easy to hang on the wall. Some warmers, in Italy or southern France, for instance, were more saucepan-shaped. You must move the warming pan constantly to avoid scorching the sheets. A bed-wagon (moine), well-known and inexpensive, is a suitable alternative according to Cora Millet-Robinet, Domestic Economy, 1853 (translated loosely from the French)
Bed Wagon
If you did not want to stand in a cold bedroom moving the warming pan up and down, you could use a bed wagon. This was a large frame designed to hold a pot of glowing fuel in the centre of the bed. The one shown in the picture is shaped like other bed wagons from southern Britain, but made of oak, rather than the more common ash.
An odd-looking contrivance, generally in use in farms in the olden days, was the bed wagon. It is used for warming a large bed, and must have done its work most efficiently. The one shown is three feet long, but they were generally larger. The woodwork is all of oak, the bent hoops passing through the straight rails, which are tied together with round rods. The whole thing is light and strong. A pan of hot embers drops into the trivet, which stands on a sheet iron tray. Another sheet of iron is fixed under the woodwork above the fire so that there is no danger of burning the bed. - Gertrude Jekyll, Old West Surrey, 1904.
The equivalent in Italy and France looked more like a sledge than a wagon: a sledge carrying a pot of glowing charcoal or wood, sometimes hanging from the top of the frame. This pot could be iron, brass or even earthenware, lidded or unlidded. Unlidded pots might be given a layer of ashes over the fuel. Italian and French bed-wagon frames are traditionally called a monk (moine or monaco) or a priest. Presumably there's some kind of people-in-bed humour there, in the same vein as the English joke about a housemaid being a "Scottish warming pan". However explanations do vary.
The picture left shows a moine propped up by the wall, and the picture right shows it with another moine and an assortment of warming pans near a big kitchen fireplace in a French castlet: the Chateau de Puyguilhem in the Dordogne.Not everyone approved of warm, comfortable beds, though. Rather like those people who criticised warm feather beds, one 1700's doctor disliked warming pans, though he thought hot sand was a helpful alternative to embers for anyone who could not bear a cold bed.
People in health ought never to have their beds warmed; not only because the fumes of the coals are in some degree noxious, but because warmth thus applied enervates the body. If however, invalids and sick persons cannot from custom dispense with bed warming, one or two quarts of sand, made red hot in an iron pot, and put into the warming pan, will be void of all offensive smell according to Dr. James Makittrick Adair, Esays on Fashionable Diseases: the dangerous effects of hot crowded rooms, c.1790
