SACC provides courses, vocational training and apprenticeships to young people and adults and is located in Southend-on-Sea.

The challenge

Southend-on-Sea Council approached Treco to assist its aim to increase energy efficiency and reduce its carbon footprint while reducing ongoing fuel costs. Treco successfully received the tender to design, supply a full turn-key installation of a 110kW L&S wood pellet biomass boiler in a 30ft containerised solution.

Our custom solution

Due to limited space on site, we had to carefully design the container to ensure that the plant room and fuel store could be accessed.  A lot of time also had to be spent on getting the right flue solution due to the height of the main building and the proximity of the flue to that building. Treco designed and installed a solution that satisfied not only the customer but also the local planning authority.

Southend refurbished their existing plant room and installed a new fossil fuel boiler and ran pipework through the main building, terminating outside of our container. Treco installed a 100kW heat exchanger in the container and made the connection into the existing system.

As the container is situated in a busy car park, we had to carefully liaise with the College with regards to co-ordinating when to deliver and place the container in order to minimise disruption.

As this is a school, reliability was a key factor for Southend District Council when deciding on a supplier. The school installed a new gas boiler to cover peak loads and any downtime of the biomass boiler due to servicing and maintenance.

Treco was responsible for a full turn-key installation, including building of the fuel store. Treco worked closely with the school in order to minimise disruption to the site and maintain heating throughout term time.

More information about the types of systems in our range can be found on the biomass boilers page.

The incentive

Southend-on-Sea Council was driven to increase energy efficiency and reduce its carbon footprint while reducing ongoing fuel costs.

In addition to the increasing the energy efficiency and environmental needs being looked after, the Council will also benefit from the Renewable Heat Incentive (RHI) scheme that will see the system generating approximately £9,500 in payments every year for the next 20 years (index linked).

Taking all of this into consideration, the ROI on this project will be approximately seven years.
