Coin activated heat pack (Sodium acetate)
This is a very pleasant heat bag.
Through crystallization of the fluid in the cushion heat is created.
By pressing some kind of coin in the cushion, the crystallization is started.
If I am cold, I just need to grab this cushion, press the coin, and then I put this pillow between my clothes.
It provides heat for relatively a long time.
The disadvantage is that it must be placed for about 20 minutes in boiling water,
to liquefy the content. After that it can be used again.
The biggest advantage of this heat bag is, that it can not get too hot.
There are cheaper brands than THERMOcomfort, but those don't deliver the same amount of heat.
I bought my first THERMOcomfort heat bag in 2003.
In 2018 I bought a larger coin activated heat pack from the brand "WarmUp".
In the picture below is the "WarmUp" heat pack at the top and at the bottom
are two "THERMOconfort" heat packs.
Brand: WarmUp (www.warmitup.nl, sold via www.cyes.nl)
Price: 18 euros (in 2018)
The quality of the "WarmUp" heat pack is good.
Clay heat bag
Brand and type: Stadtholder© Moor natural hot/cold pack 30x40cm
Price: 25,50 euros (in 2011).
This cushion is heated in the microwave.
The cushion contains some kind of clay from Germany ("moor"),
and heating it in the microwave works well.
It is easy to use, I put it a few minutes in the microwave, and then it is ready.
I only have to remember the time to set the microwave to.
One time, the cushion was not completely cooled down and I wanted to heat it a little in the microwave.
The cushion became very hot, but was still okay.
The cushion is flexible enough to place it on my neck.
After a few years of use, the plastic tore. That was because
I folded it to get it into the microwave.
Because this heat bag is quite large, it is able to contain a lot of energy.
I put it in the microwave for 6 or 7 minutes, and I turn the heat bag after 3 or 4 minutes.
This heat bag emits more heat during a longer time,
and is therefor better than other heating pads.
In 2011 I bought my second heat pad of this type.
In 2016 I still use this heat pad.
There are all kinds of gel packs.
These are usually small. So they lose their heat quickly.
Single use heat pack
A number of different brands of single use heat packs (or heat pads) are available.
I bought one to test it.
After the heat pack is taken out of its packing, it becomes warm for more than one hour.
However it is only a little amount of heat, and the way it is used has a very big influence
on the temperature. Therefore it is not very pleasant to use.
Other brands stay warm for a number of hours.
Cherry pit heat pad
Price: 20 euro.
Weight: 1050 grams.
This cherry pit heat pad must be moisturized, after that I put it in the microwave for 3 minutes.
It stays warm for a long time.
It can't get as hot as the clay heat bag,
so the heat doesn't get very deep.
After using it a few times, a seam tore and the cherry pits fell out.
So the quality was a disappointment.
Below is a cheap cherry pit heat pad:
Weight: 425 grams.
This cheap cherry pit heat pad is probably too dry,
in the microwave it gets too hot very quick,
en it stays warm for only a short time.
