Soothing heat is mainly used to treat non-inflammatory pain and for relaxation and comfort. Heat also relieves pain originating from muscle spasms, joint stiffness and cramps. Rubber hot bottles have been a tried and tested source of local therapeutic heat for centuries.

Calming Heat Pad and hot water bottle employ heat therapy that provides soothing warmth to an area of the body experiencing pain. The source of heat in the hot water bottle is of-course the boiling hot water while in the Calming Heat it is a resistance coil. Heat therapy is basically of two types- moist and dry. Moist heat comprises a wet heat source that provides relief to sore muscles, joints and tendons. Hot water bottles, steam towels and moist heating packs are some instances of moist heat. On the other hand, dry heat therapy (e.g. Calming Heat Pad), includes any form/ source of heat that does not use moisture to infuse warmth into the skin for relief.

Advantages of Calming Heat Pad over Hot Water Bottle

  • Consistent Heat – Calming Heat pad provides continuous heat for longer period as compared to rubberized hot bottle. As local heat therapy does not exceed 20 minutes you can still get an effective therapeutic heat from a hot water bottle as the water wouldn’t cool much till the therapy pasts.
  • Technically more Sophisticated No doubt Calming Heat is more sophisticated than the water bottle. It has a temperature regulator by the virtue of which you can adjust the heat intensity (up-to 3 levels). The Calming Heat Pad also has vibration settings (although reviews claim that they are of little use.)
  • Easy to Use – No doubt the rubber water bottles are bulky and heavy when filled with HOT WATER. Also heating the water and pouring it into the narrow opening of the bottle could be potentially risky for older people, particularly for those with Parkinson’s, arthritis or weak muscle strength. For such folks Calming Heat is a better option to water bottle.
  • Time-saving – Calming Heat saves time and hassle as you do not have to boil the water and also you do not have to pour the boiling water in the bag. Just plug the Calming Heat pad to the socket and you have the desired warmth in 90 seconds.
  • Easier to Carry – Calming Heating Pad is much convenient if you are traveling. You have higher chances of finding an electric socket to plug in the pad for almost instant heating, than finding a source of hot water.
  • Heats up Rapidly – Heats up in one and a half minutes. Good for that morning therapeutic heat session when you are in hurry. Or a quick evening relaxation when you are back from work.
  • No Mess – No mess since there no poring of boiling water, you don’t have to worry about your things getting wet, unlike the hot water bottle.
  • Potentially Dangerous – Make sure you do not fill the hot water bag to the brim as this exerts pressure on the valve and walls of the bag. A leaking cap can drain hot water on your body causing serious burns. So always make sure that the water is not leaking from the bag. You will notice if it is leaking by holding the bottle upside down.

Advantages of Hot Water Bottle over Calming Heat Pad

  • Cost-Effective – The most important parameter that favors the Hot Water Bottle is the price. These hot water bags are priced as low as $9 while the Calming Heat pad is priced at $60. That is 666.66% more! (six times). The disadvantages of the hot water bottle are diluted by its low price.
  • Tried and Tested Method – This is an age-old simple yet effective, tried and tested method of relieving non-inflammatory pain.
  • Good for Local Heat Therapy – The hot water bottle is more suited to treat small areas like hands and legs while the Calming Heat is only suited for larger areas like back.
  • Weighted Heat Therapy – Calming Heat is advertised as a “Weighted Heating Pad” but the hot water bottle is far better weighted heat source since it holds quite a lot of boiling water which naturally make the bag heavy.
  • Electrical Mishaps Ruled Out – There are at-least 1600 burn cases reported every year resulting from fire caused by heating pads. In most cases the fire is caused due to improper use of the pad. Though the heating pads are becoming safer, the potential electric shock and fire hazard persist, nonetheless. Relatively the burn hazards are less likely in the case of hot water bottles.
  • Gets the Job Done – Most of the time what you require is soothing heat therapy for just 20 minutes and you can get it from the hot water bottle. You don’t need a fancy electric heating pad like Calming Heat (though there are situations where the Calming Heat has a upper hand).
  • Does not cause dehydration of skin – Another important factor that make hot water bags more advantageous is the “moist” heat these bags produce as opposed to the dry heat produced by Calming Heat. Moist heat does not dehydrate the area being treated.
  • Deep Penetrating Heat – Unlike dry heat, the moist heat is “felt” deep below the skin in the muscles.
  • Use it in the Car – You can use the hot water bottle while driving a car.
  • Remains HOT for a long time – The rubber of the hot water bottle insulates quiet effectively which prevents heat loss. This makes the water bag to remain hot for a long time.


Considering the benefits, features and price of each heat therapy method (Calming Heat and Hot Water Bottle), Hot Water Bottle emerges victorious in the comparison. Detailed comparative analysis of Calming Heat Pad (dry heat) and hot water bottle (moist heat) shows that overall, moist heat is more effective, safe and acclaimed. Most observations comparing the two indicate that a hot water bottle offers better results as it. Also, moist heat, as compared to dry heat, does not require extra care on your part such as restoring moisture content as it doesn’t draw out moisture from the skin. Also, it does not cause discomfort to the skin as it’s soothingly moist. It can also be seen as a comparatively economical solution as it requires no electricity since it works only with hot water. Further, it has also been observed that it reduces pain more rapidly than dry heat in the same span of time.
