Ariston Secondary Heat Exchanger 566098

A reliable supply of instant hot water is something we all expect from a combination boiler. When the water from your hot taps starts running lukewarm or fluctuating in temperature, it’s a frustrating problem that points towards an internal fault. More often than not, the issue lies with the secondary heat exchanger, a small but essential component responsible for all your domestic hot water needs.

Restore Your Instant Hot Water

The secondary plate heat exchanger is one of the hardest working parts in a combi boiler. It acts as the transfer point where heat from the primary circuit, the water that heats your radiators, is instantly passed to the cold mains water on its way to your taps. This clever process is what gives you hot water on demand. Over time, particularly in hard water areas, this component can become clogged with limescale and sludge. This build-up restricts the flow of water and insulates the plates, preventing efficient heat transfer. The signs are usually obvious: a noticeable drop in hot water pressure, water that doesn’t get as hot as it used to, or the boiler making loud banging or kettling noises as trapped water boils inside the blocked unit.

This is where the genuine Ariston Secondary Heat Exchanger 566098 provides the perfect solution.

As an official, manufacturer-approved spare part, it is designed to restore your boiler's hot water performance to its factory standard. Replacing a blocked or inefficient heat exchanger is a targeted, cost-effective repair that can save you from the significant expense and disruption of a full boiler replacement. Installing a genuine Ariston part guarantees a perfect fit and the correct performance, ensuring a safe and reliable repair that will last.
