Description

Saunier Duval/Glowworm 0020123131 Heat Exchanger – 10 Plate DHW Unit

The Saunier Duval 0020123131 Heat Exchanger (10 Plates) is a OEM part designed to maintain optimal hot water performance in your boiler. The plate-to-plate design allows efficient heat transfer between the primary system water and the domestic hot water supply.

Over time, heat exchangers can become restricted by scale, debris, or sludge, especially in hard-water regions. This leads to symptoms such as poor hot water temperature, fluctuating output and reduced flow rate. Replacing a blocked or inefficient unit with this genuine Saunier Duval heat exchanger restores proper performance and ensures long-lasting reliability.

Manufactured from corrosion-resistant stainless steel, this 10-plate exchanger provides excellent thermal efficiency and durability, making it the ideal direct replacement.
