Product Description

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.


  • Longer Life
    Because all waterways are corrosion-free copper and bronze - not aluminum. And, SpaPak features large size, heavy duty Incoloy heating elements that lasts far longer than ordinary water heating elements.
  • Troublefree
    Because SpaPak has extra quality and safety built-in - a pressure switch to prevent operation without water flow, a high limit temperature control to prevent overheating and a dependable quality thermostat.
  • Easy to Install
    With a compact design that fits into small spaces. Standard size, full flow 1-1/2" inlet and outlet connections are conveniently located. External current leak protectors are not required.
  • One Year Limited Warranty
    Against defects in materials and workmanship (see written warranty for details). In addition, every SpaPak is thoroughly tested before shipment.
  • Sizing Guide

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.

We have a Teledyne Laars Electra Star Spa-Pak Heater TE-55. It appears that the heater element ELSR-552-2 is no longer operating. 1) Is the Raypak Flange Element 3"x3" 5.5 kw w/gasket (Mfg code 001801F) a direct replacement/fit into the existing tube? 2) If I were to replace the unit in its entirety, are the Raypak 001642 water inlet/outlet dimensions the same (10" center to center) - though on the side, rather than the rear of the cabinet as the Teeldyne?

Hi. The Raypak Element will not replace the Laars TE-55 Heating Element. The Raypak unit has an 8" center to center inlet to outlet measurement which is located on the side of the unit.

Good afternoon this will require a 50 amp breaker for the install. 240v Operation Both of the Raypak Electric Spa heaters operate with 240v single phase power. The model 552 draws about 23 amps @240v and the model 1102 draws about 46 amps @240v.

Can I used this for my salt water spa. The spa is about 750 gallons.

A     Answered on 10/17/2016 by InyoPools Product Specialist Lennox H.

Hi, David. These units can be used with a saltwater spa, for your size spa I would recommend the  11KW ELS1102 unit.

Does this heater require special wiring? Would it work for a 27 ft round pool?

A     Answered on 5/29/2016 by InyoPools Product Specialist Alex V.

Hello, Unfortunately, this would not work on an above ground pool. This is for use with spas only.

can this heater be made to go to 130 deg. I want to use for a different purpose

A     Answered on 4/20/2016 by InyoPools Product Specialist Lennox H.

Hi Fuzzy, The factor setting will not allow this unit to heat that high.

?     Asked on 5/6/2015 by Theresa

We have an above ground pool, approx 5,300 gallons. Would this heater be an OK way to warm up the pool?

A     Answered on 5/6/2015 by InyoPools Product Specialist Robert M.

Hello Theresa - The 5.5kW would be undersized. We would recommend Raypak model 001640. This is the 11kW electric heater.

How high can I set the water temperature to with this heater?

A     Answered on 7/14/2012 by InyoPools Product Specialist Patrick P.

The Raypak 001640 spa heater has a high limit thermostat is factory set at 104°F.

?     Asked on 9/29/2006 by Guest

For the 5.5KW unit how much water flow is required through the heater(570gph)?

A     Answered on 9/29/2006 by InyoPools Product Specialist Patrick P.

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.
