20 Hot tubs For Bathing Relaxation

A hot tub is a large tub or small pool full of heated water used for hydrotherapy or pleasure. Some have jets for massage purposes. Hot tubs are sometimes also known as spas or by the trade name Jacuzzi.

In contrast to a typical bathtub, a hot tub is designed to be used by more than one person at a time and is usually located outdoors. Also, the water is not changed with each use, but is kept sanitary using methods similar to those used for swimming pool sanitation.

Hot tubs are usually heated using an electric or natural gas heater, though there are also submersible wood fire hot tub heaters, as well as solar hot water systems. Hot tubs are also found at natural hot springs; in this case, the water may be dangerously hot and must be combined with cool water for a safe soaking temperature.

Effective insulation greatly improves the energy efficiency of a hot tub. There are several different styles of hot tub insulation: some manufacturers fill the entire cabinet with foam, while others insulate the underside of the shell, the inside of the cabinet, or both. Not surprisingly, many manufacturers advertise the superiority of their approach to insulation, but few independent side-by-side comparisons are available. The hot tub pump and hot tub heater represent most of the power consumption in a hot tub and vary in use of power depending on their size.
