Kim c on Apr 25, 2020
I have 10,000 gallon pool will this heater work on this pool ?
A shopper on May 22, 2020
BEST ANSWER: It would work on the Pacific oceon if left on long enough time, the purpose that I used it for was to heat a spa that is attached to my pool, I can isolate the spa and heat it alone or I can run the spa and the pool together and it does help contribute heat to my pool that measures 18 X 35 X 5 , so I think I would say that it does but at what rate over what period of time is another question.
How many amps does this unit need?
A shopper on Jul 7, 2020
Why doesn't the manufacturer list how fast it will heat a specific amount of water?
Dave C on Apr 20, 2020
BEST ANSWER: Hi Dave, I can not answer for the manufacturer or the distributor because I am only a homeowner and can only reference my experience. To calculate how fast any amount of water will take to heat would depend on 4 variables. (1) Home many heater elements 1 or 2 (2) What is the wattage rating (3) what is the flow rate of the pump (4) What is the base temperature of the water before heating. I suspect it would be difficult to perform this but if you knew these factors maybe you could hazard your own calculations. My personal experience was I had another manufacture product that finally died and it was an 11Kw single element heater. It toook about 1.5 hours to raise the temp in my spa to what was considered hot 98 degrees to get to 102 was at least 2 hours. Now I have a dual element 18Kw unit and its at 98 in 40 minutes and 102 in an hour. I like it's display but it's hard to read in daylight, at night it's easy to read. To see in the daytime I need to shroud the display. for clarity. Good luck. PS be careful about the NEC requirements for space around the device, if your electrician is a Code Book fanatic he will demand about 2 or 3 feet clearence around the unit or else no permit to install. Without a Permit there is no warranty. I took a chance and installed without so I have my fingers crossed it doesn't quit on me.
how would it work on a 18 gal pool in Pa ?
sonny o on Jan 19, 2021
BEST ANSWER: On 18 gallons it will boil the water in two minutes I bet
On 18,000 gallons it would take about a week to notice the difference
This is a spa heater, not a pool heater, the flow rate needs to be about 4.5 gallons I think
I use mine for my spa that's about 300 - 450 gallons and it takes about 3 hours to get to 103
Can this unit heat a 24 foot above ground pool?
DONOVAN G on Feb 21, 2021
BEST ANSWER: I’m only using one of the heating elements for my large spa and it heats it great, so I would say it would.
Have 15 round above ground pool will this heater work?
Stephanie on May 17, 2021
BEST ANSWER: Hi Stephanie!

This pool heater will work, but you need to consider the water temperature to begin with and what temperature rise are you looking for, since it takes a while ( a couple of days to bring the temperature up ) to increase the water temperature from the startup until it reaches the desired temperature.

Location is also important, you want the set up the pool in a sunny area and if possible, use a pool cover at all times to prevent water evaporation which is how it cools off...
Does the heater goes connected to the pool filter?
Evelyn M on Jun 17, 2020
BEST ANSWER: It is best to install AFTER the pool filter on the way out to the pool.

A shopper on May 24, 2020

could this pump heat a 18 foot round above ground pool and if so about how long would it take just estimate?
Tina G on May 17, 2020
BEST ANSWER: Depends on what state you are in. We have a 24 foot round, and it takes between 8 and 12 hours from 68 degrees to 84 degrees.

18kw Ray pac
I replaced a coats 15kw with this new Ray Pac 18kw.
I was amazed at how silent it was when energized. The 2 pole circuit on the Coats would bang when energized. The ray pac was totally quiet.
If I didn't check the amp draw on both circuits I would have thought it wasn't working.
238 volts drawing 33.5 amps on each GFI.
Time will tell on its longevity.
It's used in a residential home my only concern was the short warranty.
So far so good!

Very Efficient
Perfect for our small splash pool setup. Heater fits conveniently in ANY pool equipment area (about the size of a big shoe box)... Heats our 2500 gallon salt splash pool about 2 degrees per hour (maybe even a bit faster in that w outside temps over 70 degrees)

Operating cost will make your head spin too
Heater is great and very compact
But can understand why it’s not mentioned in the specs that it runs on 121 amps and needs. 0 gage wire to supply power

Heating element
Works great, only using half of the elements.
Still takes a normal amount of time to get up to temperature but works great.
