4 min readJan 7, 2022

Over the years, as the look and feel of sex dolls has continued to improve, sex doll engineers have turned their attention from perfecting the look of sex dolls to other areas of realism. One of these areas is body heat. Although some may miss it, the difference between a heated sex doll experience and a room temperature sex doll experience is significant. For doll owners who wish to make their sex dolls realistic, heating your dolls for use is one of the best ways to achieve this goal.

In this article we will provide a guide for sex doll owners who want to heat their sex dolls and we will cover everything from built-in heating systems to DIY home solutions. We hope you find it useful!

Let’s get started…

Internal heating systems

Most sex doll manufacturers offer an internal heating system upgrade that allows you to easily heat the doll’s body from the inside out. This method, although the most expensive, will give you the best results and keep the heat consistent throughout the doll’s body.

How does it work?

Different brands of dolls tend to have slightly different heating systems, but they work in basically the same way. The electrical cord will run through the doll’s body and there will be a plug socket somewhere in the doll’s body. The doll will also have a cord that will be plugged into the doll’s body and the other end will be connected to a wall socket. On this plug there will sometimes be a screen and buttons where you can preset the temperature you want. Once the doll is plugged in, the electricity will heat the doll to the set temperature in approximately 20–30 minutes.

For example, the internal heating system of the WM doll is wired on both the torso and the private parts of the doll. The left side of the doll’s torso has an outlet about 6 inches below the armpit. There is a wire that is plugged into the doll and the other end is plugged into the wall. The cord has a small control panel where you can set the temperature you want the doll to be heated to. Once set, the doll’s torso, vagina and anus will reach temperature and be ready for use in approximately 30 minutes.

The benefits

The most realistic experience

Continuous heating over the entire body of the doll at the push of a button

Easy to use


Extra cost — not standard with each doll

Difficult or impossible to fix if the system malfunctions or stops working

External heating device

These days, most major doll brands include a small external heating unit with the purchase of each doll. They usually include it free of charge without having to specifically ask for it.

How does it work?

The device will be a small heating rod with a USB plug that you can insert into the vagina or anus of the doll to heat it up before use. You can plug it into a USB plug that you might place from a mobile phone charger or other small electronic device. Once plugged in, the device will heat up to approximately body temperature. You can insert your doll and have a heated experience in approximately 15–30 minutes.

Alternative heating solutions

If you don’t want to spend the extra money for an internal heating system, but you are looking for something more powerful than the external heating unit that comes with it, then there are a number of other solutions that sex doll owners can use to heat their dolls. We have listed some of the more popular methods below.

Electric blankets — Electric blankets can be used to effectively heat the body of a sex doll. When used in conjunction with an internal heating device they can be almost as effective as an internal heating system. You can even look at heated clothing such as heated vests, underwear or gloves to heat certain parts of the body.

Heated lubricants — A heated lubricant is a lubricant that heats up as you use it. It is important to only use water-based varieties and they can be purchased from most places where they sell condoms. Not sure which heated lube is best? We’ve found this useful guide to warm lubricants to point you in the right direction.

Sleeping with your tpe sex doll — Sleeping under a warm blanket with your doll will keep her warm when you wake up. the TPE material will absorb your body heat and the blanket will help keep her insulated.
