Installation of 2 No. Hargassner 330kW wood pellet boilers to replace old gas-fired boilers.

Replaced aging gas boilers at two leisure centres with high efficiency wood pellet boiler systems

Turn-key installation under CDM including all building works and landscaping.

Leisure centre decreased energy usage by 50%.

Special features:

  • Leisure Centres had to remain open at all times with no loss of pool temperature
  • New BMS (building management control system) designed and built by BBSM for whole leisure centre
  • Two projects completed in tandem
  • Tight timescales for completion (both completed in a 4-month window)
  • Existing boiler houses to be used – severe space restrictions and operational challenges

Based on performance in 2023 BBSM were awarded the long-term service and maintenance contract for the entire biomass portfolio of the council.

Warminster Sports Centre, located in Wiltshire, serves as a bustling sports facility and public swimming pool for the local community. Established in 1973, the centre initially relied on two aging gas boilers, each with a capacity of 400kW per boiler, to heat both the pool and surrounding buildings. Additionally, these boilers supplied hot water for the changing room showers.

In alignment with Wiltshire County Council's commitment to achieving carbon neutrality by 2030, the decision was made as part of a decarbonisation initiative to replace the outdated gas boilers at Warminster with cutting-edge biomass pellet boilers. BBSM Ltd took charge of the project as the Principal Contractor under CDM, commencing in July 2022. The comprehensive turn-key installation, inclusive of landscaping and foundation work for a new external pellet silo, coincided with a similar biomass project at Lime Kiln Leisure Centre.

The primary challenge encountered was the need to repurpose the existing boiler plant room to accommodate the new pellet boilers, resulting in spatial constraints. Two Hargassner 330kW pellet boilers were selected for their superior quality, efficiency, and compact design, facilitating installation within the limited plant room space.

BBSM Ltd conducted a thorough system design and analysis, revealing low load periods during the summer that could lead to boiler cycling. To address this, a single 6,000-liter buffer tank was incorporated into the installation to ensure efficient year-round operation. This was an intricate of juncture in the project as we needed to hire a large crane to carefully manoeuvre this 6,000-liter buffer tank into the confined space of our newly designated pellet boiler room. With serious spatial constraints presenting a significant challenge, the precision required for this operation was paramount. The selection of the right crane and the expertise of the operators became instrumental in navigating the limited space and ensuring the seamless placement of the buffer tanks.

Despite the requirement for the Leisure Centre and Pool to remain operational throughout the project, meticulous planning allowed for minimal disruption. A temporary gas boiler provided heating and hot water during the decommissioning of the old gas boilers and the preparation of the plant room for the new pellet boilers.

To optimise pellet fuel management, a new external pellet silo with a 15-tonne capacity was installed. Load cells on the silo enable precise monitoring of pellet levels, ensuring timely orders and reducing the number of deliveries per year. The entire project, completed within four months of contract award, transitioned to biomass in November 2022, eliminating the need for gas boilers.

A subsequent analysis of heat usage over the first 12 months revealed the Hargassner boilers' impressive 93% efficiency, outperforming the previous gas boilers, which operated at less than 60% efficiency. The shift to biomass resulted in a significant reduction of approximately 40% in primary energy usage for heating, leading to substantial cost savings for Wiltshire County Council.

BBSM Ltd now oversees the service and maintenance of the biomass boilers under a long-term contract with Wiltshire County Council.

  • I would just like to pass on our thanks, to peter, for getting our heating up and running last night. he truly went the extra mile, and made sure all things checked out before he left our building. he,s a true asset to your company, and i only wished all contractors, had the same commitment to there customers. thank you once again, brilliant service!!!

    Academy- January 2024

  • You have shown us what a good (excellent!) biomass boiler installation looks like.

    You have become an essential partner in our net-zero aspirations.

    You have set a new standard for heating system efficiency.
    You have set a new standard when it comes to working collaboratively with suppliers.

    Public sector customer

  • BBSM installed the first of our biomass boilers in 2021. We found the company to be very reliable, trustworthy, and they worked efficiently and to a high standard. Based on our experience, we asked BBSM to install our second, and then our third biomass boiler system.
    We have engaged BBSM to carry our on-going scheduled service and maintenance.
    I would highly recommend them.

    Industrial customer

  • BBSM were able to provide a team of highly qualified staff across the wide range of disciplines that were required to deliver this complex project.
    BBSM's team responded with flexibility and with great professionalism when the scope of the project had to be amended due to circumstances outside of their control, and always demonstrated a solutions lead approach.
    We could not be happier with the outcome of the project. The new boiler is delivering significant fuel savings and takes considerably less time from our on site team to maintain.
    In fact, the project has been so successful we have subsequently contracted BBSM to extend the biomass system to provide hot water to a block of holiday apartments on the same site.
    I would be happy to recommend BBSM unconditionally.

    Hotel customer

  • BBSM was a professional company to work with. They stood behind their work, and we are very happy with the installation, their continued support, and their level of service.
