A fridge definitely doesn’t draw 1500 W continuously. You might be thinking of the start-up surge power draw

My double-door draws 300 W while the compressor is running (average power is obviously a lot less than that)

The heat also came from that environment in the first place. So a fridge doesn’t actually heat up a house (ignoring the negligible losses)

Very thin, can be rolled up

This but unironically. It’s a way more efficient way to lose weight than exercise. And it doesn’t come with the Ozempic side effects
