Keston guarantees quality with new five-year warranty on heat-only boiler range

British manufacturer and twin-flue specialist Keston Boilers has demonstrated the superior quality and reliability of its latest generation of boilers with the launch of a new five-year warranty* across its Heat 45 and 55 boiler ranges.

Combining leading twin-flue capabilities with one of the most energy-efficient boiler designs available, Keston’s Heat boiler range provides a perfect solution for complex installations or those requiring long flue runs. In addition to offering exceptional quality as demonstrated by the five-year warranty* the Keston Heat range is the only twin-flue boiler on the market with a fully modulating Energy-related Products Directive (ErPD)-approved pump built into the framework of the appliance, so customers can enjoy the benefits of the most efficient internal boiler pump technology ahead of the legislation changes later this year.

National sales director Alan Mason says: “Following the success of the next-generation Keston boilers as testified by our customers, we are proud to offer this five-year warranty* across the whole Heat range. The extended warranty period means that when customers purchase a Keston heat-only boiler, they know they are receiving not only leading twin-flue technology backed by specialist expertise – enabling even the greatest installation challenges to be overcome – but also the knowledge that the boilers are built to last.”

In addition to delivering a high-quality, reliable boiler range as testified to by the new five-year warranty*, Keston also delivers peace of mind to installers faced with long or complex flue requirements. Keston’s leading twin-flue technology allows Heat boilers to offer flue run capabilities up to 21m from the boiler, so the appliance may be sited on inside walls or in basements as required.

Launched in 2013, the entire Keston boiler range encompasses Heat, System and Combi boilers, all of which were designed and developed by the highly skilled R&D team based at Keston’s manufacturing facilities in Hull. Offering outputs from 30kW to 55kW, Keston boilers feature the latest energy technology and are Energy Saving Trust-endorsed, with efficiencies up to 110% part load and an impressive turndown rate of 5:1 also achieving a high SEDBUK rating.

Keston boilers are also the perfect choice for a wide range of light commercial applications when installed in cascade to achieve higher outputs from 90kW to 330kW. Installation is made even easier with Keston’s optional modular frame and header kits, which are delivered complete with all vital components such as single balance headers, safety and isolating valves and a drain point, as well as optional extras.

The range also exceeds the stringent energy-efficiency criteria of the government’s Energy Technology List, allowing small business owners to take advantage of the financial benefits offered through the Enhanced Capital Allowance scheme. In addition, the range’s very low NOx emissions at Class 5 achieve maximum points under BREEAM schemes.

Keston boilers are British Gas Service-listed, further demonstrating their high quality and the fact they are easy to install, use and service. After-sales support is also available through Keston’s Hull-based call centre team and nationwide service engineers, all of whom are comprehensively trained to respond to calls and enquiries.
