Whilst hydro therapy and water massage generated by aa hot tub is excellent
it can also be a very good idea to have a separate air blower for reasons
that I will out line below.
Not only will it also be useful as an additional massage treatment as it
bubbles and pampers the water all around you but it is said by the medical
profession that the use of an air blower will actually reduce varicose
veins.
When one gently submerges ones legs and body into warm water, the blood,
which is a fluid of a similar weight to water, will tend to become more or
less equal in weight.
This means that the pressure inside ones legs is greatly reduced and the
pulling effects of gravity on ones body are much reduced. The effect of this
is simply that the blood flow is increased and with that comes an increased
flow of nutrients.
It has been said that it is similar to having fluffy feather pillows
containing warm water and having these rolled around your torso, hips and
legs.
I am told that air blower therapy, was specifically designed by doctors to
help increase the blood circulation in veins that are contained in the skin,
legs and feet.
A Hot Tub with a separate air blower does considerably help to reduce
varicose veins.
I know many users of Hot Tubs where their varicose veins have much reduced
after they have started using the air blower on their Jacuzzi.
However many Hot Tubs do not come with an air blower and when comparing
models this is something to take into account as an Air blower will add to
the cost.
This takes us on to how a Hot Tub Spa is made as some are fully foamed which
in my view is an out of date form of construction.
The Shell can be foamed but not the contents of the whole spa cabinet. If
the whole interior cabinet is foamed then it is very hard to fix or find a
leak should one occur. This is known as a fully foamed spa.
In many fully foamed spas you often find that they do not offer separate air
blowers and of course it is not just one air blower we are talking about as
the air blower is piped to some 10 to 20 or more "pepper pot" style outlet
Jets involving some intricate pipe work.
One reason is that with a fully foamed spa the space to position the air
blower may be limited due to the foam and yet another is to do with the fact
that this out dated design means that only cold air from the outside of the
spa is used.
Hot Tubs that are not fully foamed are able to draw the air from inside the
Jacuzzi cabinet thereby re-using the mechanical heat already generated by
the pumps and related equipment.
The final and I guess clinching reason for many manufacturers is simply that
of cost. By not having an air blower they can make more money by offering
less features.
As I have outlined above it is not just a simple question of an air blower
as you do have to take into account all that intricate pipe work to the
pepper pot outlets. So if you are comparing a Hot Tub with an Air Blower and
one with out the one without will have cost the manufacturer considerably
less to produce.
Also one can draw the conclusion that running an air blower in a fully
foamed spa will destroy what ever little thermal efficiency they have. This
is simply as all of the air has to be drawn in from the outside of the Hot
Tub cabinet and this is of course colder than the water temperature in the
Hot Tub.
In the winter season, these outdated designs can make the water temperature
fall so that the heater is simply unable to keep up.
In the more modern designed Hot Tubs that are not fully foamed the air pump
is located within an insulated area so that the mechanical heat generated
from the jet pumps is naturally warming the air.
In these circumstances some times using an air blower means you lose very
little if any heat. The air coming in can be at or close to the same
temperature or even sometimes slightly warmer than the water in the Hot Tub.
. Obviously one cannot continue to always draw warm air as after a little
while the air temperature inside the Hot Tub cabinet will start to drop.
After a reasonable time span perhaps 15 to 20 minutes, the air will start to
turn cold, but by then of course you would have stopped using the air
blower.
So when you as the potential customer ask the salesman "What is the purpose
of an air blower?" you will probably be better informed than the sales
person.
