Duratech DURAPRO-17 R32 Heat Exchanger

This genuine Duratech heat exchanger is a replacement component for DURAPRO-17 heat pump units running R32 refrigerant. The heat exchanger is where thermal energy captured from the air is transferred to your pool water, making it one of the most vital parts of the system.

How the Heat Exchanger Works

Inside the heat pump, the heat exchanger acts as the meeting point between the refrigerant circuit and the pool water circuit. Hot, pressurised refrigerant gas flows through one set of channels, releasing its thermal energy as it condenses. Pool water flows through separate channels, absorbing this heat without ever coming into contact with the refrigerant. This efficient transfer process is what ultimately warms your pool.

Why Heat Exchangers Fail

Heat exchangers operate in a demanding environment, exposed to chemically treated pool water on one side and refrigerant under pressure on the other. Over time, corrosion, scale buildup from hard water, or physical damage can compromise performance. Symptoms of a failing heat exchanger include the heat pump running but not effectively heating the water, visible leaks around the unit, or refrigerant pressure faults if internal damage has allowed the circuits to breach.

R32 Compatibility

This heat exchanger is designed specifically for DURAPRO-17 units using R32 refrigerant. R32 systems have components optimised for this refrigerant’s properties, so fitting the correct part is essential for safe and efficient operation.

Professional Installation Required

Replacing a heat exchanger involves working with both the refrigerant circuit and pool water connections. A qualified engineer with F-Gas certification should carry out the work to ensure safe refrigerant recovery, correct installation, and proper recharging and testing of the system.
