Green Homes Grant Scheme - how can we help your heat pump system?

Heat Pumps and the Green Homes Grant Scheme
Heat pumps are expected to make up a significant proportion of the work on the government’s Green Homes Grant Scheme. After clarification on the government’s Green Homes Grant Scheme, we at Sentinel are taking this opportunity to bring our range of associated products to the fore.
Over the 30 years we have been providing solutions for heating systems, we have developed our portfolio of products to clean, protect and maintain both air source and ground source heat pump systems.
Air Source Heat Pump Systems
Degraded glycol in heat pump systems usually manifest itself as a brown caramel-like, viscous solution. Unsurprisingly, this does not bode well for the performance of a heating system! Fortunately, our expertise means we can sort this out easily, using our X-Range of cleaners. Typically X400 or X800 should be used to eliminate any deposited and degraded fluid, with the choice of cleaner depending on the timeframe in question. If you intend to dose and return to a system in a matter of weeks, then X400 is the product to use. If you will be cleaning immediately, then use X800. As with central heating systems, heavily fouled systems may require a higher volume and concentration of product.
Once cleaned, protecting a system is equally important, as this will avoid a similar issue arising in future. Which is where R600 comes in. 20L of R600 in an air source system will give effective frost, limescale and corrosion protect to -10˚C.
Ground Source Heat Pump Systems
Due to the generally larger size of a ground source systems, there tends to be a higher concentration and proportion of glycol in ground source systems. Sentinel have developed a cleaner solely for existing ground source systems.
Where an existing ground source system is concerned, R800 should be used. This product does not foam and does not require dilution, normally requiring only 20-30 minutes circulation to do its job, removing degraded fluid in a system. Should there be heavy fouling of the system, then longer circulation will be beneficial.
Should the ground source system be new, then our X400 cleaner, available since 1988, is the recommended cleaner.
Follow up and finish the job with either R500 or R500C to protect the installation. Offering our classic superior corrosion, scale and frost protection, we supply these in a ready to use or in a format for easy dilution, depending on how you want to work.
Both products are resistant to degradation, are non-toxic and biodegradable, so you will not see the problems that you may encounter on systems not protected with Sentinel.
Regardless of the type of heating system, any types of circulating debris can cause wear and premature failure of pumps, valves and heat exchangers. For this reason, Sentinel offer the Vortex500. Its size means capacity is not an issue, and the powerful 9000 Gauss magnet assembly means any magnetic debris will be captured, whilst the innovative Vortex Core ensures any non-magnetic debris is also captured. Should the filter become full, the filter is set up so as not to block.
The design of the Vortex500 means installation is as easy as can be - in-line installation, with a rotatble T-piece for easy siting, plus an even easier service method. You can simply flush debris through the drain valve in seconds, or remove the collar to show your customers the collected debris. No special or bespoke tool is required for the filter.
