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.
