Pool Heaters have been used for years to heat your pool or spa for optimum use. The overall efficiency of the average pool heater has improved over the last 20+ years. The average efficiency of an old gas heater used to be about 72%. That means that 72% of the heat generated by the heater is able to transfer to the water moving through it. The rest of the heat generated is lost and wasted. The new heaters of today by in large are rated at about 82%.

If you are replacing a heater that is already installed at your pool I would suggest that you replace it with the same brand heater in most cases. This is because the gas line and plumbing lines will most likely be in the same places and make the installation easier and less expensive. For instance, if your gas line comes in to the right of your old heater and the new heater has it come in to the left, you will need to run the gas line behind the heater and around to the other side (Some units do allow you to remove and reverse the manifold to the other side to avoid this issue). This is expensive and inconvenient, especially if the plumbing does not match up either.

With that said, you should evaluate  the efficiency, gas line options, and how the unit is plumbed before you decide on the right unit to install.
