When Unitary Engineering Services Ltd were tasked by One Facility Ltd, to install a new heating system which would ensure the company’s MBDA site in Bristol was as energy efficient as possible, they called on the Imax W 100 kW boiler by Ideal.

With growing Government pressure to reduce carbon emissions and an unstable economic climate forcing businesses to cut costs, it is not surprising that energy efficiency considerations have become increasingly important for many commercial operations, and One Facility is no exception.

As a result, they decided to review their existing system and identify ways in which it could run more efficiently. Unitary Engineering Services were called upon to complete an audit, and one of their first recommendations was to replace the old boiler system, with a collection of new, high efficiency condensing boilers.

Tim Clarke, mechanical engineer at Unitary Engineering Services explains: The existing heating system at the site comprised two banks of five boilers, which served the radiators and heating batteries in the air handling units. When air conditioning heat pumps were installed into half of the property, a new boiler plant was required to serve the remainder and offer enhanced efficiency for the non-air conditioned areas. One of the simplest ways to achieve this is to utilise high efficiency boilers.

When determining which models to recommend, one of our key considerations was the location of the boiler plant. The existing boilers used a flue dilution system and were floor mounted, so took up a significant amount of space. The client requested that the room remained as clear as possible and that the flue dilution was removed.

We choose the high efficiency Imax W100 as it answered our brief perfectly. Not only does it feature a wall-mounted design and adaptable flue system, but its high output allowed us to reduce the number of boilers required to six, thus saving additional space.

It was also essential that the approval of the local council was obtained for the choice of product, as the boilers had to comply with the Clean Air Act. As it offers 95.9 per cent (net CV) at maximum load and a seasonal efficiency of 94.7 per cent (Building Regulations 2006 L2), the Imax passed the test easily.

Simon Maggs, business development manager at Ideal, comments: MDBA is an excellent example of the benefits that are to be had by commercial operations who choose to upgrade their heating system.

With a correctly specified system businesses can enjoy up to 20 per cent running cost savings, as well as start tackling emissions targets set out by the Climate Change Act.

Tim concludes: We were delighted with the project and have received great feedback from our client. We look forward to partnering with Ideal Boilers on future projects.
