Would you recommend using a water bed heater under an inflatable spa?

I am planing to buy a portable inflatable spa and planning on putting it in my spare room in my house with ventilation. It doesn't have a heater and someone told me to use a water bed heater under it. Would that damage the vinyl on the underside of the spa or damage my non carpeted vinyl tile floor?
