We have an
Econo-Heat in Hannah's room on a timer.
It keeps her toasty and warm.
She has a Grobag, but only a summer weight one.
She's a really fidgety sleeper, so it's nice to know the cold edge has been taken off her room and it doesn't over heat.
I forgot to set the timer the other night and it was on from 5pm - 7am. Her room was lovely and warm, but certainly not hot when I went in to get her up for the day.
This is the second winter of using it and I love it
