Been advised it might be good to get this in my house at it’s freezing during Winter. But it’s such a hot house in Summer. So will it make it even hotter in Summer?

What is underneath the floor?

If it’s directly on the foundation, then maybe. -/ you can’t directly sink heat into the ground.

But if there’s a crawl space underneath the floor, then that crawl space is also gonna get hot in the summer, like it gets cold in the winter, and could be letting heat into your house.
