Relax with hot tubs
Hot tubs are large tubs or small pools full of warm
water; people use hut tubs for relaxation, hydrotherapy
or massage. Many hot tubs have jets for massage; if they
are located outdoors, they are protected for privacy and
bad weather. There are simple wooden-staved soaking tubs
and plastic tubs, known also as spas. Natural gas
heaters or electric heaters are the most popular devices
to heat hot tubs. There are also solar hot water
devices, really cost-effective and ecologic. Natural hot
springs can host hot tubs; in this case, the water can
be really hot and a cooling system is a must.

Wooden hot tubs and spas
As many small organisms thrive in warm water, sanitization
is vital in hot tubs. The hot tubs water composition must be
maintained to keep the proper sanitization and prevent any
damages to the tub. Wooden tubs are made with wooden staves
and steel bands. Cedar, teak and redwood are most commonly
used; inside the barrel there is a wooden bench. Spas are
made in a large scale of shapes, with a variety of seating
arrangements. Some models are equipped with water jets. The
water jet can be aerated, with moving and rotating features,
to provide a massage effect. Spas are cheaper than wooden
hot tubs, easier to install and clean, and less energy
consuming. Usually, spas have a circulator pump to heat and
filter water and another pump to drive the hydrotherapy
jets. The most sophisticated spas have computers for special
lights, sound systems, television and DVD systems. There are
also cost-effective versions of spas, made in metal but the
lack of insulation makes heating more difficult.
The newest spa models are combining the latest achievements
in technology and design, to create a beautiful, solid spa.
New features, such as the digital color change waterfall and
digital controls are allowing the customer to have an
enjoyable experience. People can even entertain their guests
in large spas, because there are large spas for 8 or 9
persons with 20 hydrotherapy jets and waterfall.
Hot tubs sanitation
It is necessary to maintain hot tub water sanitation to
prevent diseases and damage of the tubs. Water filters are
used, also chlorine and bromine, ozone generator are the
most common sanitations solutions. People can use also UV
sterilization, silver or copper ion generators.
Periodically, specialists recommend shocking the hot tub to
remove microorganisms, using potassium monopersulfate or
granulated chlorine. After the shock treatment, the hot tub
should not be used for 9 hours. Total alkalinity and pH must
be maintained, to maintain the water chemistry within
acceptable limits. Metal parts of the tub can be corroded;
chlorine and bromine will not function in the calcium
hardness is out of limits.
