Bronllys Hall in Powys, Wales is on a journey to become a sustainable events venue heated by an innovative system using vegetable oil, solar, wind, batteries – and a Megaflo cylinder.


A Victorian mansion in Powys is being transformed into a sustainable events venue using a combination of renewable and low carbon technologies, including an innovative new Hydrogenated Vegetable Oil (HVO) boiler working alongside a highly efficient Megaflo 1,000 litre cylinder. It’s believed to be the first heating solution of its kind fitted into a UK events venue.


Work underway at Bronllys Hall, parts of which date back to the 18th and 16th centuries, will create 40 ensuite bedrooms and various entertainment areas – a lot of space to heat. It was important to find a boiler solution that was suitable for the job, so Hughes Architects, the conservation architecture specialists who are managing the Bronllys project, teamed up with Suffolk-based Hounsfield Boilers to tackle the challenge.


The systems integrators for Bronllys Hall, working with a local plumbing company, have connected Hounsfield’s highly efficient UK HVO boiler technology into a thermal storage system provided by Baxi, another UK company. Manufactured in the UK, the Megaflo 1,000 litre cylinder is highly insulated to achieve low heat losses, constructed of duplex stainless steel for longevity, and maintenance-free with no sacrificial anodes.


Richard Whittington, technical sales manager at Baxi, said: “The very low heat losses of our Megaflo hot water cylinders, their renowned quality and reduced carbon footprint dovetail perfectly with the carbon neutral aims of this project as well as meeting the requirements for a long-term low-maintenance solution. We are extremely proud to be playing a part in this ground-breaking sustainable events venue which exemplifies UK innovation at its best.”

It’s a key step forward in the major renovation project at Bronllys, which aims to transform the deteriorated 18th-century structure, which retains elements from the 16th century, into a five-star events venue that operates sustainably and uses only renewable energy sources.


Doug Hughes, principal architect and managing director of Mid Wales-based Hughes Architects said: ​


"Along with our other partners in this expansive project, Hounsfield’s technology and Oil4Wales’ logistics enable HVO heating to work at scale with high availability - another step in creating a fully sustainable historical building alongside our work with battery technology from Brill Power, whose battery management system will extend the lifespan of the building’s battery system. The batteries are charged by sustainable sources, with minimal reliance on renewable power from the grid.


“HVO is a highly effective way to solve the difficult issue of decarbonising heating, with options to scale for the future and deliver on our collective commitment to sustainability. This approach not only gives incredible projects like this a competitive edge through delinking from carbon-intensive fossil fuels and their price swings, but also adds further to its core eco credentials, aligning with the team’s sustainability targets."


The team aims to complete the first stage of Bronllys Hall’s transformation into a carbon-neutral event venue by the end of 2024, setting new precedent for event venues, hotels and businesses. In the process, Bronllys Hall is intended to become a showcase for UK homegrown cleantech innovation, giving confidence to commercial building owners and developers seeking to install renewable and sustainable integrated systems.
