The Best wax heater: Our Picks

In the old days, women used to melt the wax they were going to use for hair removal in a water bath using a pan on the fire. The method was not at all practical, as as soon as a few minutes passed, the wax would cool down and needed to return to the cooker.

What is a wax heater and where to use it?

Before we talk about the wax heater, let’s explain a little more about this hair removal method, which can be done with cold or hot wax (we’ll limit ourselves to talking only about hot wax in this article).

Waxing can be done on small or large areas. When the wax is applied to a certain part of the body it begins to cool and harden, sticking to the hair.

After the brief interval between application and full hardening, the wax is pulled back in the opposite direction to the hair growth, removing the hair from the root (follicle).

Total procedure time varies depending on the area being waxed, but the correct way is to apply wax to small portions of skin at a time to prevent the wax from breaking.

The heater will serve to melt the wax and keep it hot during the procedure. Check out the advantages and disadvantages of this product:

  • It serves both to melt and to keep the wax warm
  • There are versions for conventional wax and for the roll-on type
  • The devices can be found in the versions for home or professional use
  • They are relatively inexpensive devices
  • In the case of the thermocera, there is a certain difficulty in removing what is left of the product after it hardens
  • The roll-on wax heater does not have temperature control

Thermocera or roll-on wax heater: which one to choose?

There are two types of heaters for wax: the conventional heater for honey wax, which is called thermocera and the roll-on type.

Conventional Honey Wax Heater

The conventional heater is very similar to a pot, both in shape and size (and also because it has a lid). The capacity of this type of heater varies, there are models for domestic use for 400 g of wax.

This device is electric and has several interesting features such as thermostat, temperature control knob (up to 6 settings) and operation indicator light.

The heater serves both to melt the blocks of wax and to keep it warm (just lower the temperature). The coolest thing is that the part of the heater that is in contact with the wax can be preserved with the use of an aluminum or plastic refill.

The base, where the resistance is located, does not need to be changed, unless it is defective or breaks. It is made of ABS plastic (very resistant).

Roll-on wax heater

The roll-on wax heater is composed of a heating base, which may have one or two heaters and has the same format as the roll-on wax refill, only it is larger.

It is very easy to handle. Just place the wax refill inside the device, close the lid that comes with the heater and wait for the wax to soften. The temperature control is automatic. See how easy it is to handle the roll-on wax heater:

After about 30 minutes (this time can vary from one device to another, so keep an eye on the instruction manual), you remove the heater from the base and can use it normally.

There are devices in which the base serves for only one refill, this model is more intended for domestic use. The devices for two or four wax refills are indicated for professional use.

The roll-on wax heater has transparent sides, which you can use to check the consistency of the wax during the heating process and the level of product available.

Learn now the main differences between the roll-on wax heater and the conventional wax heater:

Roll-on Wax Heater Thermocera
Type of wax used Roll-on wax refill Tablet or granulated wax
Heating time 30 minutes Depends on the temperature selected on the thermostat
Advantages Easy to clean, low energy consumption Agility to melt the wax and strict temperature control
Disadvantages Time to melt the wax Difficulty to clean
Price The device costs £ 60 on average Depending on the size of the device, varies between £ 120 and £ 190

How much does it cost?

The roll-on wax heater with support for a refill costs between £ 60 and £ 90, devices with base for two refills cost around £ 90 and those for four units cost almost £ 200.

The thermocera can cost between £ 120 and £ 190, depends on the size of the device, being the smallest around £ 120, the medium size around £ 140 and the largest for £ 190.

Purchase criteria: Factors to compare wax heaters

Before choosing a wax heater, you need to decide which method of hair removal you are best suited to, whether it is the roll-on, where sheets of paper are used to remove the product, or pulling the wax itself after it has dried.

Only when you have made that decision should you buy the items you will need for waxing. To choose the best wax heater you should observe the following criteria:

  • Type of heater
  • Capacity
  • Refill
  • Temperature control
  • Voltage

We will explain each of these items in this section, to remove all your doubts and help you choose the best option.

Type of heater

There are two types of wax heaters: roll-on and conventional. They differ in format, weight, size, technical features and price.

  • Roll-on wax heater. It has an electric base with one or two heaters, which is plugged and connected to the container that will receive the wax refill. The temperature is automatic.
  • Thermocera. It is composed of two parts: the plastic structure (which hosts the electric resistance) and the internal metallic part. You can place the wax directly on the metallic part or on an aluminum refill that can be attached to the base.


Both the thermocera and the roll-on wax heater have versions with different capacities. The roll-on wax heater can be purchased in versions with one, two or four refills.

The thermocera comes in 150, 400, 700, 1000 or 1200 gram block or granulated versions. The smaller devices are for domestic use and the larger versions are intended for professional depilators.


With refill we are not referring to the wax, but the piece that should be used as support to melt it (in the thermocera). This component can accompany the device or be purchased separately.

If the device is for personal use there is no need to buy or even use the refill, you can put the wax directly on the base of the device. However, if the appliance is shared, it is more hygienic for each person to have their own refill.

Temperature control

The roll-on wax heater has automatic temperature control, but the thermocera has manual adjustment, with six temperature options, the maximum being 100º C.

It is normal that when selecting the temperature, the operation light oscillates between on and off, because after the device reaches a certain degree, the thermostat automatically turns off and on again to maintain that temperature level.


Both models of wax heaters are bivolt appliances. In the case of the thermocera, the button to select the voltage of the appliance is located on the bottom of the piece and you should remember to select it every time you change the plug. The roll-on wax heater is also bivolt.
