When electricity is the energy choice Raypak is the quality choice -- dependable, trouble-free, performance-proven - with corrosion-free, 100% copper and bronze waterways. Two compact models - 5.5kw and 11kw - built to last by the company renowned for reliability.
SpaPak spa/hot tub electric heaters furnish sustained heat to provide the maximum benefits of hydrotherapy...including stress reduction, relaxation and arthritis/pain relief.
The following table shows the heating capability for each model in temperature rise per hour with a given amount of water. For example, the 11kw unit will raise the temperature of 450 gallons of water 10 degrees Fahrenheit in one hour. To determine the gallonage of your spa, multiply the surface area x average depth x 7.5.
How long does it take to heat an inground jacuzzi of 900 gallons by 25 degrees with the Spapak Electric Spa Heater? When the jacuzzi is not in use can the power be shut off at the heater?
Hi, Hans. It will take this unit approximately, 5-1/2 hours to heat 900 gallons of water 25 degrees.
I have a 15,000 gallon in-ground pool. What kind of heat pump would you recommend? Or could I run the Raypak 001640 Spa-Pak 11kw 240V for 24 hours to get the desired temp since its a smaller unit?
Hi, Jonathan. We will need additional info in order to size a heat pump for your pool. I will need your city. the desired temperature, run time and the operation months. You can also use the Raypak Heater Sizer. This 11kW heater will not effectively heat your pool.
how long will it take to heat an ice cold 16x48 above ground pool that holds 5000gallons of water
Hi, Robert. It depends on what temperature it's heated too. This unit can increase your pool temperature by about .75 to 1 degree an hour.
Is there an optimal flow rate for this heater? I know 60 is the max, would 60 get the spa up to temp the fastest or would a lower flow rate be more efficient? I have a variable speed pump and an inline flow meter. Therefore I can adjust the flow.
Hi, Andy. This unit is designed to heat efficiently with a max flow rate of 60 GPM. The flow switch cannot be adjusted outside 15-60 GPM.
I have an in-ground pool/spa. I plan to only heat my spa by isolating the spa when using the heater, only circulate water through the spa. My question is when I am not using the spa I plan to have the heater powered down, it would be to expensive to heat the pool. Is it okay to still have water circulating through the heater when it is off? Also is it okay to have no water circulating through it if i plan to have a valve to completely shutoff the heater when not using it. Thank you
Hi, Jared. Yes, its okay to have no water or water circulating through the heater when it's not in use.
my pool is an above ground oval 4 ft high 12 feet wide and 18 ft long. will this heater keep it warm enough ? i currently have a hayward gas heater and i don't like it. i have had 3 in the last 10 years. i now only want a heater that is only electric.
Hi, Elaine, This unit will not be adequate, I would recommend an Above Ground Pool Heat Pump.
Will this work with a salt water chlorine generator in my 8' x 30" vinyl sided round above ground pool?
Hi, Greg. This heater will work with the proper installation and size filtration system.
WHICH IS BETTER AND WILL LAST LONGER? 11KW RAYPAK 11KW HAYWARD SPA ELEC HEATERS 11KW PENTAIR? I LIVE IN COSTA RICA SHIP EXTRA ELEMENT WOULD THAT BE NECESARY?
John, Both would last the same amount of time. The main this is to closely monitor the chemical levels so that the water is not corrosive to the heater. You can purchase an extra element to keep on hand as a back up.
Is 15 gpm (900 gph) the required flow to keep the 11 KW heater on or is it higher for the 11 KW model?
Hello Nick- The Spapak Electric Spa Heater / 11 KW - 001640 will require a minimum flow rate of 15 gpm and a maximum flow rate of 60 gpm.
How many gallons is the max to heat?
Hello Robert- This is a spa heater, so there isn't a set size for these heaters. I wouldn't use this on more than a 900 gallon spa.
I have a spa heater ELS 1102-2 volts 240 amps 46. I am wondering how much electricity it will consume if you run it 24/7 in the winter time. This is our average temperature in the winter time: November (5 C/41 F, -2 C/28 F) ; December (0 C/32 F, -6 C/21 F), January (0 C/32 F, -7 C/19 F), February (3 C/37 F, -5 C/23 F) ; March (9 C/48 F, -2 C/28 F). Could you please tell me how to calculate the electricity consumption ? Thank you tons! Jady
Hi Jady. To calculate how much it will cost to operate this unit you can use the following steps. 01) Amps x Volt = watts 02) Watts / 1000 = kW 03) kW x Hours = Usage 04) Usage x kW rate = Cost
when heating spa can you just put it on circulate or do you need the full pump on?
Hello Tim, to heat your spa full unit/pump needs to be on.
i work at a hotel. and my spa motor went out this weekend. replaced it today and now i have a flashing code. could you tell me what it means
Hello Steve, you might just need a diagnostic run on it from Raypak 805-278-5300, was it the same model that you had previous or different?
I have an older Jaquzzi spa with electric water heater. Model # is Els-11002.Did they change the numbering subsequently to Els-1102? they are bot h 11KW, 240v All the information on the element is as follows. 6550561,,E83,,731xj0005,,240v,,,11000w. Are the new elements compatable with the older models?
Hi Larry, The model numbers have changed but the parts are the same. The Raypak 11 Kw Element (001802F) is the element used with this unit.
What are the electrical requirements for this product? Standard outlet or something more substantial? Also, would this be a sufficient product for an 8,000 gallon above ground pool? Currently my pool is too much in the shade and only gets to about 76 degrees from limited solar blanket exposure. Would like to increase at least 10 degrees. Any idea about cost to increase a pool this size 10-12 degrees as mentioned? Thanks.
Hi Mike, You can find the electrical requirements Raypak SpaPak 552 & 1102 Tech Data Sheet. It has 1-1/2" NPT male connections. The Spapak Electric Spa Heater / 11 KW would not be suitable for an 8,000 gallon pool. You will need multiple unit or go with the Hayward Heat Pro Heat Pump 50k BTU Digital Display Above Ground Pool.
I have a 400 gallon built in spa located outside in Michigan. Which size heater would be appropriate?
Hi Robert, For a 400 gallon spa the Spapak 5.5KW Electric Spa Heater would be the appropriate size but the Spapak 11KW Electric Spa Heater will heat the spa faster.
What is the amps for the 11kw unit?
The Raypak 11 kw spa heater draws 46 amps.
My hot tub is a side extension of my main (in ground concrete) pool. Can this unit be placed exposed to the elements alongside my pump/filter equipment?
Hello David, the spapak Electric Spa Heater part #001640 is rated for both indoor and outdoor installations.
Is this a single phase or 3 phase heater?
The 001640 Spapak Electric Spa Heater is single phase 240-volt.
How high can I set the water temperature to with this heater?
The Raypak 001640 spa heater has a high limit thermostat is factory set at 104°F.
For the 5.5KW unit how much water flow is required through the heater(570gph)?
The flow should be maintained above 15 GPM (900 GPH). Failure to do so will cause the pressure switch to drop out, and the heater will become inoperative.
2 to 4 hrs
Screwdriver, Nut Drivers, Adjustable Wrench, PVC Fittings and glue
Most would tear it out, but for $2,300 with new lighting and a few bugs ironed out, the hot tub is at it's best in years.
Although the Spapak 11KW Spa heater went in easy, I thought the heater was faulty as it failed to heat past 86 degrees and AC indicator would not illuminate, and half the dual breaker would trip. A write up in the trouble shooting steps showed that the over pressure switch trip point comes set for a single speed pool pump during the vendor testing. The two speed hot tub pump would over pressurize and trip the relay. All it took is a 1/4 turn counter clockwise till the relay released (Clicked). Now it is working great and the tub will run up to 102 degrees, which has been great on these cold winter days....getting out into the cold breeze is the only hard part.
(5 out of 5 stars) Heats my 2400 gallon pool
Reviewed By: coleen from Washington State ()
Pros: Effective. Easy.
Cons: Yes, you have to do wiring.
I just wanted to take the 'edge' off the cold in my outdoor portable 6X12 pool. This takes the pool (2400 gallons) from 61 to 68 in 3 hours... BIG difference for me for my exercise swim. I easily wired it to a GFCI disconnect box and my 1hp pump/filter. The pressure gauge on the pump showed no difference after installing the heater. Very simple, effective. We'll see how soon i'll have to use the section of the manual that tells how to replace each part :)
(4 out of 5 stars) Electric Pool Heater - as hot as you want it.
Reviewed By: CARLA R. from STRATFORD, WI ()
Pros: It does what it is suppose to. It has an adjustable thermastat. It will shut off if the pump is shut off. Warms up pretty quickly.
Cons: The electric bill gets really huge.
This electric pool heater works very well. It was able to heat a 7500 gal pool up as high as I wanted it to go. I actually went overboard one day up to 104 degrees F.
(4 out of 5 stars) Electric pool heater
Reviewed By: smokieroo from Branson, MO ()
Pros: With the wire on and fixed. it runs great
Cons: Heater should be inspected better before shipped out
Nice heater, heated my pool over nite. Only thing is. It was missing a very important wire. Would not work. I had to have my contractor work a extra hour, pay him to get the wire, pay for the wire. and that cost me. I believe that I should get a rebate back because of the missing wire.
