Main Features:
Titanium Element
The E3T has a robust titanium heating element that not only prolongs the life of the heater, but allows it to work in extreme pool water environments, such as salt water chlorinated pools.

I have a small 6,000 gallon salt pool. How many BTU do I need? What model do you recommend?
Damon E on Nov 22, 2019
A shopper on Jan 4, 2019
BEST ANSWER: It depends on the amount of water being heated. 450 gallons is about 10F/hour.
You can ratio this rate to your specific volume. Examples:
900 gallons would be about 5F/hour.
300 gallons would be about 15F/hour.
will this heat a 15,000 gallon pool? How long would it take to raise 5 degrees?
jon p on Jan 29, 2019
BEST ANSWER: NO - Don't even think about it. I have 700 gallon spa. Took over 2 hours to raise 10 degrees. Well made unit and best price/performance unit in its class, but not for your size. I had to mule this to Costa Rica or I would have purchased next size up. My other pools are 15k & 60k gallons. I purchased gas 400k btu units for both of those. I would never purchase anything smaller or you are looking at days to make a pool comfortable.
what are the dimensions?
A shopper on Jan 9, 2019
This could use on a above ground 18 round pool?
A shopper on Sep 3, 2019
BEST ANSWER: Technically yes, however it is quite undersized for a pool of that size. It’s meant to be used in a portable spa which is typically covered and left hot all the time.
Best electric heater for 10,000 gal above ground pool? Thanks
Monica B on Apr 25, 2021
A shopper on Feb 12, 2021
BEST ANSWER: Water weighs 8.33 lbs/gallon, so 9000 gallons of water weighs about 75,000 lbs.
A BTU is the amount of energy needed to raise each pound of water 1 degree F.
So, if you want to heat 9000 gallons 2F per hour, you need 75,000 x 2, or 150,000 BTU.
There are 12,000 BTU per ton of heating, so you need 12.5 tons to get a 2F/hour heatup rate.
Similarly, 6.25 tons will give you a 1F per hour heating rate.
Does this come with a chord to plug in to an outlet?

I have a 24 ft above ground pool what size heater do I need?
A shopper on Jun 15, 2020
Does this unit have a buiilt-in pump?
A shopper on Jul 21, 2021
BEST ANSWER: No, it uses your pool pump and turning the valves to the hot tub or you will need to plum in a separate hot tub pump and plumbing.
Will this heat a 3000gallon swim spa?
Joe B on May 17, 2020
BEST ANSWER: My spa is 800 gallons and takes about 5 hours to heat up . I believe it will but will take a while .
Would the 11KW unit raise 60 degree water to 90 degrees on one pass?
Kevin H on Aug 17, 2020
BEST ANSWER: I don’t think so. The unit has 15 GPM minimum flow rate. At that flow the actual rise from input to output is low. It heats a lot of water slowly rather than a little water fast. In my application it heats ~600 gallons of water 8 degrees per hour with a flow rate of about 25 GPM. If water was unmixed that would be 8 degrees in 24 passes, or .33 degrees per pass.
Is this heater multi flow? Can the water go either way thru the heater?
Jim K on Jul 21, 2021
BEST ANSWER: Mono flow, one way
What is distance between centerline of top and bottom water connections?
Jim K on Jul 21, 2021
Do other components need to be purchased?
A shopper on Nov 29, 2020
BEST ANSWER: The heater is hard wired in so you would also need to purchase basic electrical supplies and plumbing. The heater is a complete unit, only supplies for the install are needed.
I have a 5k Gallon above ground vinyl pool. Will this work for me and will it work on propane?
Greg R on Nov 5, 2020
BEST ANSWER: No, if you have propane you need a gas heater. I have the electric one. A 5K pool is huge and the Raypak electric heater is for a spa. If you want to heat a pool, depending on geographical location, you'll need a huge propane heater.
I have above ground pool 24ft. would this heater work?
Mary W on May 21, 2020
BEST ANSWER: Yes would take a little longer to heat but I have 15 ft and it is heated at 84 steady

Works great!
Works great! Installed in a 1000 gallon baptismal, heats up to set 86 degrees within 4 hours. Only issue was I need to review the breaker specs, we had a 40 from last heater, changed to the required 60 just to (in spec).

A great little pool heater
A very efficient heater that is easy to install. The small size hides its effectiveness well. I am using it on a 2500 gallon endless pool

Working as advertised
Replaced a 1989 11Kw Raypak unit. So far, so good.
All features discussed in the owner's manual are working.
The noted heating rate matches the 11Kw rating.
Getting an 8F/hour temperature increase for about 550 gallons and a 2F rise across the heater at 42 gpm flow.

Quality Good - Performance fair
700 gallon spa takes 3 hours to get hot. Nature of beast. I would have purchased next larger unit, but too large for export shipment.
