Worcester Adds System Filter To Award-Winning Greenstar Range

Leading heating and hot water appliance manufacturer, Worcester, Bosch Group, has enhanced its award-winning Greenstar range of high-efficiency boilers with the launch of a new high-capacity system filter.

As the first boiler manufacturer to add a system filter to its product portfolio, Worcesterhas once again underlined its support for the installer by allowing heating engineers to offer their customers a boiler and compatible filter under the same brand. The twin action Greenstar system filter has been designed to capture both magnetic and non-magnetic system water contaminants, protecting the boiler and wider central heating system components.

The Greenstar system filter comprises of a high-capacity cyclonic trap capable of capturing non-magnetic particles, whilst the filter also boasts the strongest magnet available, which can capture up to 200mg of magnetites per year. This optimum combination of features ensures the end-user can benefit from improved heating comfort and no reduction to the life expectancy of any “water facing” components.

Thanks to the inclusion of pre-formed copper tails, a dedicated spanner and a quick dose valve for adding system chemicals, the Greenstar system filter is simple to install and service, with a guide installation time given by Worcester as just 15 minutes when installed with a new or replacement boiler.

MartynBridges, director of marketing and technical support at Worcester, Bosch Group, comments: “Our long-term strategy has always been to give installers and their customers the chance to benefit from the complete system solution and the introduction of our Greenstar system filter is our latest commitment to that.

“With domestic energy bills on the rise, homeowners are well-advised to do all they can to improve the efficiency of their heating system. Our extensive field trials found that the Greenstar system filter can save  on annual energy bills and reduce CO2emissions  when compared to a system containing contaminated water and can simultaneously prolong the lifespan of the boiler and system components. From an installer’s perspective, the installation of a system filter allows their customers to significantly limit the risk of boiler component damage, which can prove costly to repair.”

The launch of the Greenstar system filter follows Worcester’s recent Which? Report success. This year, for the second year running, Worcester, Bosch Group once again performed excellently within the Which? Report, where no other manufacturer scored higher. The brand scooped an impressive 23 Which? Best Buy accreditations for its range of Greenstar gas-fired boilers, including its new CDi Classic range. Worcesterwas also placed in the category of ‘The most reliable gas boiler brands’ in the latest survey of Which? panel members.
