### What is "Heat Load"?

Heat load refers to the amount of heat energy to be removed from a space in order to achieve the desired temperature within the space. There are three types of heat load you should consider when calculating the total heat load in an application:

1. External heat load
2. Solar load/design
3. Internal heat load

![heat-load-ebook-2022](https://info.eicsolutions.com/hs-fs/hubfs/heat-load-ebook-2022.png?width=400&name=heat-load-ebook-2022.png)In our eBook, Understanding Heat Load, we'll explain:

- How to calculate external heat load
- How to calculate solar heat load
- How to calculate internal heat load
- How to use the results of your heat load calculations to properly size and select a cooling system

[**Download the guide**](https://info.eicsolutions.com/guide-to-heat-load#form) to learn how to accurately measure the impact of all heat sources on your application and how to properly estimate what size thermoelectric cooling solution you will need to thermally manage them.
