What are the Best Cupro Nickel Pool Heaters? – MY EXPERIENCE

Spread the love

The difference between Cupro nickel pool heaters and copper heating elements is that cupronickel is known for offering increased durability and longer service life – despite exposure to saltwater, pool chemicals and more while copper is more subject to corrosion.

That’s right! Cupro-Nickel is similar to the gloves you wear on your hand rather than just use your hand for things. You can still wear a hole in your glove, it will just take longer. However, that does not mean you shouldn’t take care of it.

In my experience, pool chemistry is the primary factor of any pool equipment longetivity. Keep the water clear, clean and properly balanced and, with a minimal amount of preventative maintenance, you’ll get even longer years out of your equipment.

Copper Vs Cupro Nickel Pool Heater Vs Titanium Heat Exchanger

The primary reason for Titanium and cuprinickel is because copper cannot stand with SWGs that have become really common. Cuprinickel and titanium is the way to go if you plan on upgrading your SWG (or even if you don’t).

Best Cupro Nickel Pool Heater

I had a client who accidentally overdose on the muriatic acid last week and the pool water Ph fell drastically. She did not even know this until this morning and now has a possibly damaged copper heat exchanger. She is not the first customer I have seen with a similar problem. The result of this is high copper levels and stains in their pool because of the heat exchanger. It just takes one sudden OOPS! With the acid and there could be problems. This does not happen with Cupro Nickel pool heaters though.
