The heat exchanger plays a very important role in the function of your pool heater. The exchanger is the part of your heater that actually warms your water, converting received energy into heat that can easily be transferred. The heat exchanger is exposed to water flow, moisture, chemicals, and extreme temperatures and over time, these elements can take their toll.

When pool owners discover that their heater is in need of a new heat exchanger, it can be daunting. Because the heat exchanger is such an essential component, many people consider purchasing an entirely new heater. But, if the rest of your heater and plumbing are in good shape, finding a replacement heat exchanger is a way to save money and be more environmentally-conscious when repairing your heater.

The Pentair 474059 Heat Exchanger Kit is suitable for use on MasterTemp and Max-E-Therm Heaters that are rated at 250K BTU. It is important to take the time to make sure that the 474059 is the right fit for your heater so there are no delays in getting your heater up and running again!
