The earliest recorded type of hot water bottle was the bed warmer. Going back to the 16th century these where filled with embers from the fire and placed into a metal pan with a lid. Many still survive today and can be seen in copper form with long wooden handles that helped move the hot pan across the bed to warm all corners. You can still find old hot water bottles and bed pan warmers in antique fairs. These bed warmers took hot charcoal or embers from the fire to heat up the metal pan. Some had perforated vents to let out more heat and most where decorated with motifs, family crest or motto's. Mass manufactured so many still survive today and if in good condition can still be used!

Often the stone cap would be replaced with a cork alternative to seal the hot water, the stoneware hot water bottle below has it's original stone cap and in excellent condition. Because they were mass produced and very robust many survived so the antique value is not great. Many stoneware hot water bottles are still in use today and will be for years to come.
