Description

Description: Do not heat sea water or salt water ST series pool heaters are special used for small pool less than 13CBM, massage pool and hot spring to heat and keep warm; Meanwhile, can be a assistant for heat pump in heating. This product adopts latest constant temperature controller, temperature sensor replaces traditional magnetic flow switch, it improves greatly of trouble free in working time, adaptability of water environment and stability Features: Manual reset temperature control switch:Once unexpected high temperature 60℃ occurs, the temperature switch cuts off the system. You need to cut off the main power supply, resolve the fault and wait the temperature to fall below normal temperature, then press the ‘Reset’ button to restart the heater Unique control system: ST series are the newest generation with our unique control system. With this advanced control system, the traditional mechanical water flow sensor is replaced by modern digital temperature sensor, and the features of the temperature Sensor technique are: A. The flow-temperature sensor is always under the control of software, accurately monitoring the temperature status of the whole system, and then adjust the settings to maintain the water temperature and protect the heater from unexpected situations B. No mechanical sensors, avoid any mechanical failure to affect the function of the heater C. Avoid affection of ion accumulation to mechanical sensors D.

    • Does not work but a few months.
I returned my first order and received another unit. That unit only worked for a short time. Again the unit is not working. I get an over heating blinking Hc code that can not be reset or corrected. I am currently trying to help from the Welcomeget seller. I hope that I can get a response to fix this heater or it is only an expensive piece of junk. I thought there was a 1 year warranty. The maximum temperature is the default when the unit is powered on. This means if it were working then you have to watch the temp because it will become too hot for humans to be in the water. ... show more

    • Simple install, cost effective
I bought this because the cost of using this 11kw unit vs running a propane/gas heater was massive. When I received it, I was surprised at how quickly I was able to install it inline with my pool/spa system. Less than 2 hours. It is beyond simple/easy to operate, which is a definite pro. I recommend simply planning a little ahead when heating any body of water however, as it takes at least a few hours to get up to temperature. If you've got that easy step down, then you'll enjoy it as much as me! ... show more

    • Decent pool heater, but know what you are buying
Review Image by Shane Monsees Shane Monsees
First off, let’s get one thing straight, this is a Chinese knock off of the Coates 11kW heater. Do not think you are getting the same product as you are not. I knew this when I bought it, but just wanted to be clear. Also, I am a mechanical engineer and had an electrical engineer go over the unit prior to install to make sure that it was safe as this is not a UL tested unit. Overall, the heater is decently made. The wiring is within spec for the amount of current it will be drawing and the crimp connections were good. I added a 3 position terminal block (McMaster p/n 9130K42) as using wire nuts on a 240v 50amp connection is kinda sketchy. There was a broken sensor wire (happened during shipping, no fault of the manufacturer) that I had to repair, but other than that the unit functioned out of the box with no issues. The “PUMP WORKING” light is not wired in, and to make it work requires soldering in some wires. The instructions are vague and translated in the manual, but they are there. The only thing I will gripe about is that it does not have a mechanical sensor to detect minimum flow thru the unit. It uses 2 temp sensors and infers flow thru temp differential. This works, but can be fooled causing the unit to heat when the pump is not working. I added a mechanical flow switch (McMaster p/n 2766K43) and a relay to shut off the main power relays if no flow was detected. I also used this to drive the “PUMP WORKING” light. Do not attempt to do this modification unless you are comfortable with high amp power systems as a screw up can cause major issues. Took about 6 hours to go from 72deg to 80deg with the cover on. Pool setup : * 3300 gal above ground pool in So-Cal * .5 hp, 900gph pump with 14” sand filter * 1-1/2” supply and return lines Installation notes : * Use at least #6 wire to supply voltage to the unit * You must use a GFI breaker to feed this unit!! There is no ground fault protection in it!! Not doing so is unsafe!! * Unit pulls 48.7amps of 240v AC. I have it on a 50amp breaker with no issues. * Unit will not work in salt pools. The heating elements will corrode and stop working, or worse cause electricity to leak into the pool. ... show more

    • Wouldn't recommend unit.
Unit heated the water in our pool faster than I thought it would. The on off switch should have been water proofed. Unit defaults to maximum temperature, 44 degrees C, if power is turned off then back on. The unit really needs a water proof cabinet and would've preferred a terminal strip for the high current connections. Had unit in service for 6 weeks and disconnected unit and stored for the winter. Reinstalled unit for the spring and it doesn't work. Troubleshooting guide doesn't help, haven't been able to get a response from seller. ... show more

    • Great cheap heating option.
Heater worked great on a 3500 gallon above ground pool. Only issue I had was my power cord was too long and the wire (8ga.) was overheating. Once I shortened it, it worked great.

    • Scam
These will trick you into thinking it's a Coats heaters which are amazing and last forever. I bought 5 of these. 3 have caught fire and burned up. I've turned these is for copyright and misleading branding. Do not buy
