HI All,
I have a 333K Sta-Rite heater installed on my 18x36 IG with spa. The spa is separate and in winter we usually close the pool but leave the spa open (until about Christmas) After that I close it because it gets REALLY cold. Anyway, the manual said not to operate it when temps are below 40f and I'm curious as to why. From September to December it definitely gets below 40f.
Thanks,
J.
I'm wondering if this is the reason my Raypak went south in less than 4 years:confused:
All heaters produce condensation on the outer surfaces of parts within the unit
(sort of like a cold drink on a hot day will "sweat").
When it's cold out, the heater will produce a lot more condensation within the unit, because of the low temperature of the air circulating in the unit. So, it won't suddenly explode the first time you use it in cold wx, it just shortens its life somewhat. That's what my spa heater service rep told me. Of course if you use only use it occasionally when it's that cold out, I wouldn't "sweat" it :-) No idea why your older unit died in 4 years. Could be a number of issues.
Thanks for the reply. I figured as much. I used to use my old heater about 3-4 times a week in the winter. That particular unit was a Raypak Versa 2 and it was outside in the elements which could have added to the issue. I left it on for 18 hrs to get my pool up to temp this spring and the thing started leaking at the top manifolds which is an apparent problem with those units when you fire them for extended periods. I took it apart to try and fix it and it was rotten. Having said that it was constructed with standard nuts and bolts while my Sta-Rite has all stainless fasteners etc so hopefully it will last longer.
$1500 later of course
:(
PS I should also add everyone at the pool company told me it was my water but they didn't know I am about as anal as they come with my Taylor K-2006 test kit. They also tested my water and no copper present so the thing essentially rotted from the outside. At least that's my thinking.
