Pool Heater Checklist

From Swimming Pool Steve

A swimming pool heater is the most expensive piece of equipment on an equipment pad, according to this post from Swimming Pool Steve.  What is surprising is that most swimming pool owners don’t take any steps to protect their heaters from damage due to water chemistry, improper bonding, and lack of proper maintenance.  Wouldn’t it be great if there was a checklist for the swimming pool owner to follow in order to protect thsi pricey investment?  Well, look no further:

Pool Heater Checklist

Your pool heater is the most expensive piece of equipment on the pad – make sure your heater is protected against early failure by following this pool heater checklist! If you are looking to replace your heater then be sure to read the pool heater reviews by Swimming Pool Steve.

Pool Heater Water Chemistry

The most important factor that will determine how long a pool heater will last is how well you balance the chemicals in your pool. Chronic imbalance of water chemistry values can ruin in a heater in a single pool season if they are bad enough so great care should be taken to learn about how to balance your pool water. If you think that you might need to brush up on your pool water chemistry then you should read the Pool Chemistry Crash Course.

Chlorine levels that are too high will corrode the internals of a gas heater, calcium that forms on metal components will deteriorate them rapidly, and pH that is too low or too high will destroy them faster than any other way. You can see now how your heater is subject to advanced decay from multiple water chemistry variables – imagine if all of these values are not within balance just how fast your heater can become damaged. Heaters that have been destroyed from chemical damage will have obvious signs on chemical damage inside and most manufacturers will not honor heater warranties for products that show chemistry related damage.

A pH level of 7.0 is 10 times more acidic than a pH of 8.0
A pH level of 6.0 is 100 times more acidic than a pH of 8.0
A pH level of 5.0 is 1000 times more acidic than a pH of 8.0

Understanding that the 0-14 pH scale is logarithmic it is easy to see how having your pH out of balance creates a drastically more corrosive environment for the heater. Compound this over the life of the heater and pH imbalance is easily responsible for most pool heater failures.

Pool Heater Bonding

The most likely way that your heater is not installed correctly would be the absence of a bonding wire connected to the casing of the heater. This bonding wire is in place to protect against galvanic corrosion, which is a major cause for early pool heater failure. While some pool companies do bond pool heaters, most existing swimming pool heaters are not bonded at all which will absolutely reduce the service life that you will get from it.
