FM1746 Biomass Service and Maintenance

Wiltshire Council own and manage a portfolio of Biomass pellet boilers that serve a collection of Schools and Leisure Centres. There are eighteen installations comprising of twenty-nine boilers from varying manufacturers. The boilers provide space, water and swimming pool heating and are therefore integral to the operation of the council’s building estate. Wiltshire Council has a requirement for Biomass Servicing & Maintenance, and is therefore seeking quotations from suitably experienced and qualified Contractors to provide scheduled servicing and maintenance across the biomass portfolio including associated ancillary equipment and other miscellaneous equipment installed on Wiltshire Council controlled premises. This includes an annual Silo clean and biannual flue clean. The contractor is expected to ensure that the boiler systems are maintained in a safe condition, ensuring their continuous function, and preventing the risk of injury to any person or damage to any property. The Contractor shall also provide an emergency breakdown repair service (including out of hours response), and regular ash clearance from site. The contract will require the appointed company to have the skills and experience to work with all biomass boiler makes and models on the council’s portfolio (see below). Furthermore, they will have experience of maintaining biomass pellet boilers (not just chip boilers) and of working with commercial scale boilers in large, complex operational buildings. It is a requirement of the tender that the winning contractor be registered as a HETAS Approved Biomass Maintenance Scheme company. Well maintained biomass systems ensure the heating and continued operation of council facilities. They also ensure that the Renewable Heat Incentive subsidy is guaranteed and that the costs of maintaining and fuelling the boilers are therefore subsidised. Furthermore, well maintained boilers ensure that the associated emissions from burning biomass pellets are kept at regulated and compliant levels. The continued operation of efficient biomass boilers is, in fact, part of the agreed aims of the councils published Climate Strategy. A prompt and competent reactive maintenance service will ensure that a building remains open and usable and that any heating failures do not affect the operational capacity of the building. The list of boiler makes and models is as follows: Hargassner HSV 58 Windhager BioWin 60 Hargassner Eco PK 330 Hargassner Eco-PK 225kW ETA PC50 Froling TX 200 Remeha Gilles HPK- RA 75 Hargassner HSV 200 Hoval STU425 Hargassner HSV 109 Froling T4 pellet Pelletfire Plus The successful contractor must have a high degree of technical knowledge and expertise in the pellet boiler field and be able to respond within a sufficient timescale to emergency breakdown call outs. Specifically, it is expected that the contractor will seek to: • Raise the standard of maintenance to include proactive attention • Conform to manufacturers guidelines • Standardise cyclical maintenance activity • Increase standardisation of equipment and systems across the biomass portfolio • Purpose improvements and resilience of boilers in the biomass portfolio • Raise the level of compliance assurance within the biomass portfolio • Provide out of hours and reactive cover • Provide a detailed Planned Preventative Maintenance Schedule • Ensuring the service efficiency • Ensure an annual flue cleaning service • Ensure an annual pellet silo cleaning service • Ensure a regular ash disposal service The council currently has 16 sites that are RHI accredited and the successful contractor is expected to have a thorough understanding of the requirements of the RHI scheme, particularly for a ‘complex’ system, in order to ensure that those boilers are maintained to the expected standard and that the RHI income for the council is preserved. The contractor is expected to work with the council to ensure ongoing compliance with all present and any future RHI regulations as set out by OFGEM. It is expected that the contractor will have reasonable access to all parts from all relevant boiler manufacturers, and that they will carry a stock of critical spares. Engineers attending school sites must have a current and valid DBS check.
