## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    ~300 watts verified
  

*by M***T on Reviewed in the United States on September 29, 2024*

I measured the element with connecting bars attached. Ohms measured 0.5 ohms, 12 V/0.5 ohm=24 amps, 24x12=288 watts. This will give a decent amount of heat to keep water from freezing.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Versatile and useful product for solar and wind turbine installations!
  

*by T***Y on Reviewed in the United States on December 15, 2019*

I have used these for years and never had one fail. With the two elements, they can be configured for half-load (one element), full load 12V (factory config with parallel jumpers) or full load 24V (move jumpers to series the elements). As such, they are perfect dump loads for solar and wind turbine use and can store energy as hot water. The 1" NPT fittings fit many common water heaters.
