Sentinel SystemCheck online offers clear benefits

Service allows users to access heating system water ‘health check’ reports quickly.

SystemCheck, the established water analysis programme for central heating systems from Sentinel, is now available as an online service. This progressive move means that installers, contractors and homeowners can access detailed system water quality reports within just three working days, helping to ensure that boilers and heating system components are protected from corrosion and limescale. The new SystemCheck portal allows users to submit sample details and track samples online simply by entering the reference number printed on the form found in the SystemCheck pack.

The SystemCheck service has long been recognised as a reliable system health check with regard to validating the water quality and correct treatment in domestic heating systems – important since poor-quality system water will inevitably cause corrosion and limescale build up, leading to a host of costly problems including component replacement, system downtime and even complete boiler failure.

Notably, the service includes a report compiled by an independent, ISO 17025-compliant laboratory that certifies the results of sample analyses, making recommendations for further action where appropriate. The objective is to check that a heating system has been correctly cleaned and then fully protected with Sentinel X100 inhibitor.

For installers seeking confirmation of a job well done - as well as a handy, added-value sales tool for customers - Sentinel SystemCheck can provide rapid validation. To ensure the boiler is fully protected, it makes sense to check the system is commissioned in line with UK Building Regulation Part L requirements, which recommend using quality water treatment and scale protection products. In fact, failure to do so could invalidate a boiler’s warranty and lead to an unexpected large bill in the event of a breakdown.

SystemCheck is commonly used when commissioning new heating systems, but also when replacing components in older systems - even those 20 years old or older. It is also ideal for identifying problems with poorly treated existing systems, allowing users to take effective corrective measures promptly, or for performing a general health check to ensure that a system is working efficiently.

The kit comes with everything needed to provide water samples for analysis. A returnable plastic box is supplied containing two sample bottles (one for mains supply water and one for the system circulating water), each with a unique identification number and easy-to-follow instructions. A pre-printed Freepost envelope is included for sample dispatch. Customers then simply go online to track the results.

SystemCheck is a crucial part of “maintain” in the CPM (clean, protect, maintain) mantra that constitutes the core of Sentinel’s recently introduced Sentinel System. The Sentinel System is a three-step programme of cleaning, protecting and maintaining heating systems to ensure lifetime protection against scale and corrosion, and ultimately deliver best-possible system performance and efficiency.
