Festo's Requirement
As part of Festo’s commitment to the environment, they were soon to be applying for ISO 14001 certification (Environmental Management), and in preparation for this they wanted to reduce harmful carbon emissions on site by replacing the 2 obsolete and no longer efficient Ideal Concord CX boiler systems with more environmentally friendly alternatives – in-house discussions had taken place within Festo’s CSR team about the possibility of introducing fully electric powered boiler systems in place of natural gas.
OKEL's Commercial Boilers Solution
At the time of the site survey, we first wanted to address the customer’s initial thoughts surrounding the introduction of electric-fired boiler systems in place of gas and to see if this was a viable and cost-effective option for the customer moving forward.
Regardless of the fuel type chosen, Festo required approximately 200kw of heat to heat the areas. We explained that the key consideration would be future running costs. By looking at the difference in the customer’s energy tariffs between the cost per kw/h of commercial gas versus commercial electric – it was very quickly identified that this would not be an affordable option moving forward, as the cost between the two tariffs was simply too great to justify the move away from gas.
Instead, we proposed the installation of 2 x high-efficiency ATAG Commercial XL110 natural gas boiler systems. The boilers are already Hydrogen Blend Ready which will enable the boilers to blend up to 30% Hydrogen with natural gas for when this greener hybrid fuel type become readily available throughout the UK’s gas networks. They also have an outstanding gross efficiency of 99.3% which theoretically recovers 99.3 pence for every £1 of gas used.
Unlike older boilers that have no modulation feature, ATAG’s XL boiler model is fully modulating which allows the boiler to use the exact level of heat needed in real-time – this feature means that the boiler is incredibly efficient when it comes to fuel usage and in turn will reduce energy consumption and harmful emissions, and save on energy bills.
A modern & high efficiency boiler can save up to 40% on your energy bills. ”
Installation / Results
The installations were completed on time and at a time to suit the customer and included the decommissioning and removal of the obsolete boiler systems.
After the system had been fully installed it became apparent that the customer’s existing pressurisation unit in the plant room was now showing signs of failure and age-related wear and tear, resulting in loss of pressure.
Upon request from the customer, we were able to supply and install a brand new Flamco Flexfiller that would complement the new high-efficiency boiler systems and deliver optimum performance.
