Water test kits & testing service
Understand what’s really happening inside your system. Test your water quality and protect performance.
Poor water quality is one of the biggest hidden causes of inefficiency, breakdowns and long-term damage in closed-loop heating and cooling systems. Corrosion, scale, bacteria and unbalanced pH quietly eat away at performance, driving up energy use and maintenance costs. Blended’s Water Quality Test Kit gives you a simple way to find out what’s really going on inside your system. Send us a sample and our lab will analyse it, identify the problems, and provide clear, practical recommendations to bring your system back into balance. It’s quick, straightforward, and designed to help you protect performance, extend system life and avoid costly failures.

Improves heating and cooling system efficiency
Helps your system run more efficiently by reducing restrictions, contamination and performance losses caused by poor water quality.
Helps prevent corrosion, scale and bacterial growth
Reduces the conditions that lead to corrosion, scale build-up and bacterial growth inside closed-loop systems.
Identifies underlying water quality issues before they cause damage
Highlights hidden water quality problems early, before they develop into blockages, breakdowns or component failure.
More benefits of our Water test kit service
Supports better heat transfer and system performance
Cleaner, better-balanced system water allows heat to move more effectively through the system, improving overall performance.
Reduces long-term maintenance and repair costs
Fewer system issues and breakdowns over time mean lower maintenance costs and fewer expensive call-outs.
Extends the working life of boilers, pipework and components
Protects critical system components from premature wear, helping equipment last longer before replacement is needed.
Provides clear, practical recommendations you can act on
Gives you straightforward, system-specific guidance on what needs fixing and the most effective way to fix it.
Applications - how our water test kits and service helps our customers
Blended’s Water Quality Test Kit can be used across a wide range of heating and cooling systems where water quality directly affects efficiency, reliability and system life. From large commercial plant installations to smaller domestic heating systems, testing provides a clear picture of system health and helps identify issues such as corrosion, contamination and bacterial growth before they lead to reduced performance or costly repairs.

Why water quality matters in closed-loop systems
Water quality sits at the heart of how well any closed-loop heating or cooling system performs, yet it is often overlooked until something goes wrong. Over time, untreated or poorly balanced system water can lead to corrosion, sludge build-up, bacterial growth and scale formation. These issues restrict flow, reduce heat transfer and put additional strain on pumps, boilers and heat exchangers. The result is higher energy consumption, more call-outs, and premature component failure.
A simple way to understand what’s happening inside your system
Blended’s Water Quality Test Kit is designed to take the guesswork out of system maintenance. The process is simple. You request a free test kit, take a sample from the system following the clear instructions provided, and send it back to our lab using the pre-paid packaging. Our technicians then carry out a full laboratory analysis to assess the condition of the system water. This builds up a clear picture of what is happening inside the system, rather than relying on assumptions or surface-level checks.
Clear results and practical recommendations
Once the analysis is complete, you receive a detailed report outlining the current state of the water quality. This includes indicators such as pH balance, presence of bacteria, and signs of system damage or contamination. Crucially, the report does not just tell you what is wrong. It provides practical, tailored recommendations on how best to remedy any issues and maintain the system going forward. That might include guidance on inhibitors, biocides, flushing requirements or corrective treatment plans.
Real technicians, not automated reports
Unlike generic testing services, Blended’s approach is deliberately practical and human. Your sample is analysed by experienced technicians who understand real-world heating and cooling systems, not automated black-box processes. The advice you receive is tailored to the type of system you are running and the issues identified, whether you are maintaining a commercial HVAC installation or looking to improve the performance of a domestic heating system.
Free to start, clear costs for lab testing
The initial test kit is free, making it easy to get started and remove the barrier to checking your system health. The laboratory analysis is charged per sample, with the cost made clear upfront. This means engineers and building managers can make informed decisions about when and where testing is worthwhile, rather than committing to long-term contracts or unnecessary ongoing costs.
Built for engineers, useful for property owners
For heating engineers, plumbing contractors and HVAC specialists, the test kit provides a professional way to demonstrate system condition to clients and back up maintenance recommendations with hard data. For property managers and homeowners, it offers reassurance and a clear route to improving system efficiency and reliability. In both cases, the goal is the same: fewer problems, better performance, and longer-lasting systems.
