Optimum Efficiency for Central Heating Systems Sentinel Jetflush 4
Are your rooms cold in winter when they should be warm?
Does the noise of the boiler wake you up before the alarm goes off?
Does your central heating system regu-larly break down?
Then let Sentinel show you how to make your central heating system trouble free and operate efficiently.
If your heating system is to work as effectively as possible, keeping your home warm and heating bills low, then it has to have the right environment in which to operate.That's a clean system, that gives it every chance to deliver the very best performance it has been designed to provide.
Corrosion and scale debris in the system are the most common source of problems with a boiler and heating system. You may notice cold spots at the bottom of your radiators, a noisy pump, or boiler, or just that the whole system is not heating the house as it used to anymore.

Before - This infra-red photograph of radiator before treatment clearly shows the cold spot created by a sludge build up.
As you can see from the picture above it is not unusual for a radiator with several years service to have a significant level of debris present. This debris will prevent the radiator warming the room. The image was taken with a special infra red camera which shows heat output across the radiator.
This radiator has a build up of sludge which is clearly producing a massive cold area on the radiator.

After - the same radiator after treatment shows sludge and cold spot removed with system returned to full efficiency
The image on the right was taken after the heating system had been jet flushed with a Sentinel cleaning product. The sludge was removed and the system restored.
This not only means a warmer house, but also a more efficient boiler, consuming less gas, and contributing to the environment by emitting less Carbon Dioxide.
So, why put up with central heating problems when there is a simple solution?
Sentinel has developed the Jetflush 4 unit. It is designed to be used with Sentinel chemicals by your plumber or heating engineer and will quickly remove deposits and sludge through its powerful flushing action. This can restore your central heating system to maximum efficiency. It's a simple and easy procedure that carf'be completed in less than one day.
Following the use of the Jetflush 4 unit, your heating engineer will add Sentinel X100 inhibitor for long-term protection, because an untreated system is not only at risk of further scale, corrosion, boiler noise and sludge, but bacterial growth could also be a problem.
Jetflush 4 from Sentinel - the easy way to a better, cleaner system.

Engineer/Installer information
It is accepted amongst manufacturers and professional installers of the need to ensure correct installation, commissioning and servicing of central heating systems.
The need to flush systems to remove sludge and installation debris prior to installing a new boiler is a major part of the Benchmark process. There is even a British Standard BS7593, which gives the relevant code of practice and the latest Building Regulations require flushing and treating of all new boiler and system installations.
