The heat light will not come on?
david c on Dec 9, 2015
BEST ANSWER: I've had one of these for over a year and have had no problems. For troubleshooting, the first question is whether it is heading the water OK, in which case maybe just the light is bad. If it's not heating the water, then there must be something bad with the heating system itself (electrical connection or heating element).
What other accessories would I need for a 24-11 Coates Heater?
A shopper on Aug 2, 2021

hi i need the union for this heaters? model: 12411st 11 kw
Alaen S on Mar 27, 2016
BEST ANSWER: HI,
I am plumbed with schedule 40 PVC and unions are available any where that handles that pipe. I also plumbed in a gate valve as my hot tub water level is above the heater outlet. That way if I need to remove the heater I can cut off the water and unscrew the union. I hope this helps.

Will this heat a 1750 gallon above ground Intex 12’ dia pool to roughly 80deg?
A shopper on Jul 11, 2020
BEST ANSWER: And he’s my 9 x 18 x 42” pool to 90° and probably higher if I wanted I have an above ground InTEXT pool
I have an Intex above ground pool. Its 18ft round and I believe 52inches deep. Will the 11kw heat it enough. I'm not trying to make it feel like a hot tub or anything, just take the chill out. Also, how long would it take to take the chill out of the water? Estimate of course...
Paul N on May 19, 2020

How do you drain the spa?
A shopper on Apr 3, 2018
BEST ANSWER: Hello shoper,
In my case I just use a submersible pump and in a couple of hours the 800 gallons spa will be drain.

Hope this helps.

Dear friends send me pls manual for 11 kwt 3x380 v heater and electrical diagram how to connect it to the electricity?
Many thanks.

Igor G on May 11, 2021
Hi, would this heater work in a small 600 gallons over the ground spool? I love in orange county Ca and i’d like my spool to get at least to 100 on the coldest days.
A shopper on Jan 14, 2021
I am looking at this to provide supplemental heat to just my spa. The main heater will keep the temp up to 85-90ish. For this type of application, would the 5kw work or do I need the 11kw? I am looking to raise the spa 10 more degrees than the pool.
John K on May 18, 2020

Not too hot
The heater was not very strong and did not warm the water well. It registered as if it did but it didn't.

Damage
Heater was damaged in shipping and had to have repaired before it could be used. Pool Supply support was willing to replace any broken parts but repair did not require parts, just labor. Installed now and is working well. Great heater for my hot tub. Thanks Pool Supply..

It can be made by putting two heating elements or three he knew Melman's and one unit. It takes 90 minutes or more to heat
They have to be installed correctly correct wiring and breaker switch breaker switch for each unit . Where I live in the desert there's not that many pool people that know how to install unit.
