Technical details

WORCESTER GREENSTAR 25 Si (10 plate) DHW HEAT EXCHANGER 87161066860

Product Overview

The Worcester Heat Exchanger 87161066860 is a heat exchanger designed for use in selected Worcester heating appliances. The heat exchanger is one of the boiler's primary components, transferring heat generated during combustion to the central heating system water while keeping the combustion gases and system water separate.

As part of the boiler's heating system, the heat exchanger plays a vital role in supporting efficient heat transfer, reliable operation, and overall appliance performance.

ℹ️ Product Condition Options:

This item is supplied as Refurbished. Please verify compatibility before ordering. 

Technical Insight & Common Servicing Requirements

The heat exchanger is one of the most important components within a boiler and is continually exposed to high operating temperatures, combustion by-products, and circulating system water. Over time, normal wear, corrosion, or system contamination may affect its performance.

During routine servicing or repair work, engineers may inspect the heat exchanger for signs of:

  • Internal or external corrosion.
  • Scale or debris restricting heat transfer.
  • Water leaks or signs of deterioration.
  • Reduced heating efficiency.
  • Preventative replacement during major repair procedures.

A faulty or damaged heat exchanger can affect normal boiler operation and may result in reduced heating performance, water leaks, loss of efficiency, or appliance shutdown.

This Heat Exchanger (MPN: 87161066860) is suitable for use in selected Worcester heating appliances, including compatible models within the Greenstar 25i Combi ERP, Greenstar i System, Greenstar i Junior HE, and Greenstar 25Si boiler ranges.

Please strictly verify the manufacturer part number (87161066860) against your boiler's technical manual or existing component before ordering to guarantee correct fitment.

Safety Advice: Boiler parts involve gas, water, and electricity. Installation must be carried out by a Gas Safe registered engineer.
