Wax melts as much of itself as possible and never gets hot enough to melt some warmers, or to melt just a little bit of wax when using the best wax melts. An old-fashioned wax burner heats very slowly. However, the wax gets heated more quickly in some of the very best wax melt warmers.
This is due to the coil heating more quickly when the wax melts. These wax melt warmers never burn the wax or melt it much more than they should. There are several brands of wax melts available, but the two brands with the best reputation are Remco and Remo.
I am partial to Rexmo, but I will also use Remco wax melts if they are in stock at a store near me. Many of the wax melts sold at stores are of dubious quality and may melt too much of the wax, or not enough of the wax to melt, which causes the wax to dry out on the bottom of the bowl, and then remain hot for a very long time before being removed.
The best heater is a Wax candle melt warmers because it is heated at a very low temp. There are several different types of wax melting heaters available in the market. Here is what you should look for when looking for wax melt warmers:

Types of Wax Melts

Remco Wax Melts – These are just called “wax melts”, but they are excellent heaters for melting wax. Remo Wax Melts – These are best because they do not allow excess heat from the wax to warm your freezer. The wax melts hot but is not too hot.

Wax Melts

Warmers – These heaters melt wax much faster than a simple wax warmer, and tend to melt wax even faster than some wax melts. They tend to melt too much of the wax too quickly, causing the wax to be pulled out from the wax melt warmer and melt a bit more on the bottom of the bowl. When the wax melts faster than a simple wax warmer, there is usually wax on the wax warmer to melt off the wax on the bottom of the bowl.

Wax Melt Heats

Remo – The only wax melt heater that comes close to melting wax evenly, with an equally warm bottom layer, is the Remo. The others tend to melt wax more unevenly, which results in some of the wax melting and then becoming cool, causing more wax to melt out. The wax on the bottom of the bowl tends to melt a bit faster than the top layer of wax melting on top.
Remco – The only wax melt heater that uses a wide bottom temperature heating coil to melt wax evenly. This is the only wax melt heater that provides a warm wax layer on the bottom to melt more wax evenly. These heaters have many problems. In order to warm the wax to the proper melting point, the wax needs to melt enough to warm the wax melt heater, but not too much, so that it cannot melt more of the wax.
Therefore, some of the wax melts can get warm enough to melt most wax melts, if they are not in use. Some wax melts have cracks and fissures in the wax, allowing the wax to get in the cracks and melt. Wax melts heated in such heaters tend to be cold, because the wax melts itself just a little bit, but never really melts because the heaters are not heated enough to melt the wax. Also, in the heaters, wax melts do not cool off on their own, so they remain warm to the touch.
Here are some coolers and wax warmers that are on the market, and seem to be of good quality:
Glade – Two brand-name wax warmers are available in the market, but the best wax warmers in my opinion are the Remco and Rexmo wax melts. They are cheap, but offer a fairly warm and even wax melt, and a wax warmer that cools quickly, and does not overheat. They are not cheap, so I only have two of them. I love the new Cool Ice electric hand warmer. I use it in the shop sometimes, and it is nice and warm and keeps my hands from getting too cold.

Remco Wax Melts

I like this product for the cost, and how it heats the wax very evenly. I do not like the wax being so cold on the bottom when I use it. A wax warmer without a warm bottom can warm the wax too quickly. Wax melts heated in a cool bottom heaters tend to be cool in the top layer, and hot in the bottom layer, which is not what I like, because it cools off the wax a little more. A cool wax melt warmer can be too cold.
The wax melts not always heat evenly on the bottom. However, I have had good experiences with both wax melts. Rex seems to melt more evenly than most and does not heat up too quickly, unlike Rexmo Wax Melts. Remo wax melts also heat up quickly, in the same way, Rexmo wax melts.
The Warmers do not heat the wax evenly but do melt some of the wax. Therefore, there is some wax left over at the bottom of the bowl, and the wax can be melted by a heat source warmer like this one. Some wax melts have a warmer side, and some do not. The wax melts warmer and tends to melt more of the wax than the coolers. Most wax melts heated in wax melt heaters will melt some of the wax in the bottom, but not all.
If you want to meet a whole piece of wax, not just part of it, these wax melts heaters are best. There may be wax on the wax melt warmer when you first get it, and most wax melts heaters have a small amount of wax on their bottom after the wax has melted. In the case of the Remco, this is a small amount of wax that melted on the bottom.

Remco Wax Melts Heat Within Seconds

The bottom of the Remco wax melt heater has two cooling coils. This cools the wax in the bottom of the heater slightly. It does not heat the top layer of wax evenly. The wax melts warmers like this one can not melt the wax that is melted, since the wax melts slowly on the bottom, and does not melt quickly enough to get the heaters going fast enough. The bottom portion of the heater has a plastic sheet over it that fits very tightly and absorbs wax that falls off the heater.
Most wax melts heaters do not have a plastic sheet over them, so the wax melts heated in these heaters tend to melt the wax evenly on the bottom, and melt it a little too much on the top. Wax melts heated in these wax melt heaters heat up quickly, but cool down fast. The wax melts warmers melt faster than the top layer of wax melts on top. This allows a hot wax layer on the bottom to melt more wax.
This makes the wax melt warmer perfect for melting wax. However, wax melts heated in cool bottom heaters melt the bottom layer of wax faster, but still slower than the top layer of wax melts. Wax melts heated in cool bottom heaters melt the bottom layer of wax a little more evenly than the wax melts heated on top.

Top Layer of Wax Gets Hotter Than Lower Layer

Most wax melts heated in a cool bottom heaters melt wax on top of wax melted in the bottom layer. The top layer of wax can be a little hotter than the bottom layer of wax. However, the top layer of wax is hotter than the bottom layer of wax. I like this since it makes for a warm wax that melts very evenly.

Temperature Will Still Melt if Watered Down

Since wax melts heated in a cool bottom heaters melt wax better than a wax melt heated in a cool bottom heater, it still seems to melt the wax even if the top layer of wax is cooled down. If you simply keep the wax from being watered down and keep the top of the wax warm, it still seems to melt the wax that is not warmed, by making it hotter than the top of the wax. Wax melts heated in cool bottom heaters melt more wax evenly than wax melts heated in cool bottom heaters.
This is especially true in warm wax melts heated in cool bottom heaters. If you water down the top layer of wax or keep it warm, the wax melts heated in cool wax melts heated in a cool bottom heaters will melt the wax that is not warmed. This may result in some wax melting too warm, and some melting too cool. However, in some cases, if you follow this rule, the top layer of the wax will be melted and the bottom of the wax will still be melting, with wax melting evenly.

Wax Melts Warm As Long As Warm

Wax melts warmed in wax melts heated in cool bottom heaters are warming the wax a little more quickly than wax melts warmed in cool wax melts heated in cool bottom heaters. wax melt is heated in a cool bottom heater warming the wax a little more quickly than wax melts heated in a cool bottom heater. This results in wax melting faster than the top layer of wax melting heated in the cool bottom heaters.
The wax melts heated in warm bottom heaters can melt the wax that melts warmers as long as the wax melts warmed in cool bottom heaters, regardless of whether the wax melts heated in the bottom or top layer. The bottom and top layers of wax melt warmed in warm bottom heaters seem to melt more slowly than the bottom layer of wax melts heated in cool bottom heaters.
This means the wax melts heated in warm bottom heaters seem to melt a little bit slower, than the wax melts heated in cool bottom heaters. However, wax melts heated in warm bottom heaters seem to melt the wax a little faster than the wax melts heated in cool bottom heaters. This is another good reason for keeping the top of the wax warmed. The top of the wax can get warm as long as the bottom and top layers of wax are melting as they are heating, and melting evenly.
