How to add product bundles with different prices?

Question

Good afternoon. How to add a product with several configuration options so that after changing the configuration, the price immediately changes.
Let's say I have 3 types of boilers, each of them has five types of power (9kW, 25kW, etc.) but there is only one model.
How to make it so that the buyer could choose exactly the power that is needed through the list? I thought that when viewing the product there would be checkboxes with power, I ticked the box and the price changed. Is it possible to do so?

This is organized using the options on the product edit page. When adding an option, you can specify the amount that will be added / subtracted from the cost when it is selected.
