Fernox System Health Check

Fernox System Health Check is a postal sampling service designed to assess the condition of your central heating system. It’s like a health screening for your boiler and pipes—without the stethoscope.

What It Does

• Analyzes system water: You send in samples of your heating system water and fill water (e.g., from your kitchen tap).

• Detects issues: The lab checks for problems like corrosion, debris buildup, or incorrect chemical dosing.

• Provides a diagnosis: You receive a clear report with recommendations to improve system performance and longevity.

How It Works

1. Fill two sample bottles—one with heating system water, one with tap water.

2. Complete the enclosed order form.

3. Send everything back in the provided Freepost envelope.

4. Results are delivered via email, the Fernox app, and web portal within 72 working hours.

Why It Matters

• Helps maintain efficiency and extends the life of your heating system.

• Ensures correct use of Fernox treatment products.

• Offers peace of mind before or after system maintenance.
