| Scheme: | Replacement of end of life oil boiler with ETA 100kW pellet unit |
| Boiler and plant: | IETA PC100kW pellet boiler with external buffer tank. Full system control using the ETA in built controllers, two hot water cylinders and integration into open vented existing radiator circuits. |
| Fuel | The boiler is expected to use around 35 tonnes of wood pellet, producing over 150Mwh of heat per annum. |
| Pellet storage | External pellet silo. |
| Grant /Funding | The system was funded by the PSDS (Public Sector Decarbonisation Scheme) as it is part of Bristol Council Net Zero targets. |
| Savings /Investment | Switching from oil, the property is saving on energy bills and removing many tonnes of Carbon Dioxide over its life span. |
| CO2 saving | Compared to gas heating, our wood pellet systemreduces CO2 emissions by over 95%, equating to1611 kg CO2 saving per year |

Replacement of end of life oil boiler with ETA 100kW pellet unit
Project overview.
Deanfield Study Centre is a Council owned property in the Forest of Dean, offering a range of outdoor activities for large groups of children. The centre was originally the engine house for the coal mines, but now is repurposed to offer young people a chance to explore the outdoors.
The oil boiler used for heating the site was well beyond its expected life span and was unreliable and in-efficient. The PSDS (Public Sector Decarbonisation Scheme) provided a chance to receive funding to replace this as well as help with the Councils commitment to Net Zero.
Space in the existing plant room was very limited, so an external pellet store and buffer tank were specified and the installation carried out during the school holidays to minimise any downtime of the heating system. Water treatment was added in the form of an IWTM Chemical free system which keeps the pH and dissolved Oxygen in check, extending the life span of the system.
