Gatsby/Imperial uses 2 rating of heaters and a variety
of sizes and styles.
Simply stated, the heater is an element that when
electrical current applies to it, it resists the current
and doing so creates heat. Because the element resides
in the spa water you can destroy an element in less than
a year or with water care, extend the life to over 5
years. The average is 3-5 years.
Since the element is in the water, it's the #1 cause of
the gfci popping. You must replace to correct. Sometimes
you see corroding heater posts, sometimes on the element
itself, and many times the "short" is hard to see. But
is short what is happening is electrical current is
leaking from the heater element to the water and the
gfci is sensing it and shutting off the spa. That is
GOOD. Means you will not be shocked or electrocuted.
The ratings of the heater is designed to match the
current you supply the spa with the heater current draw.
The most common spa is designed to operate on
220-240vac. You should expect about 5 degrees
per hour.
The most common heater is the VERTICAL heater. Its a
canister to the right of the control box. The other
style is the HORIZONTAL heater which lays flat below the
control box.
The VERTICAL heater comes with or without a pressure
switch and either 4.0 or 5.5kw elements. The most common
is the 4.0 or 5.5kw with a pressure switch. If your spa
doesn't use a pressure switch you can still order this
heater and just don't use it. The price of the heater is
the same.
To ID whether you have a 4.0 or 5.5kw heater you read
the label on the heater. To ID whether you have a
pressure switch or not is simple. Heaters with a
pressure switch have an extra cord coming from the
heater and plugging into the control box. This socket
will be labels PS or Pressure Switch. Again, it's better
to get a heater with and not use then to order the wrong
one.
With advice
from us that we offer upon request after you order, we
can walk you through the replacement.
Why did it last such a short time?
This is a common question so I'll cover it. The element
is designed to be in balanced, quality spa water. I see
heaters lasting 7-8 years. That tells me the owner takes
care of their water and it's from a good source. I would
expect to get about 4-5 years on a heater. If lower,
first look at your own water checking habits. Very, very
often when repairing a spa with a local customer they
will insist they check the spa water weekly but by the
end of the conversation they admit they check
occasionally and probably didn't get it right. That is
why I always recommend a good relationship with a local
spa store that knows the local water. They will help,
which leads me to the 2nd reason heaters fail: water
source.
In parts of Denver the water is HARD; others soft. HARD minerals
attach to the element and cause it to fail. With a
local, quality chemical source they can walk you through
dealing with local water. If you have pure surface water
deposits aren't a big problem but most of us don't have
soft water so it is. But this again helps us to
understand having a local retailer walking you and
checking your work will give you longevity with your
heater. One OEM of heaters claim if the customer keeps
their water quality HIGH that the heater will last for a
long, long time.
