| Scheme: | Upgrade of unreliable pellet boiler with new ETA system |
| Boiler and plant: | ETA PC80 kW pellet boiler replacement. Full system control using the ETA in built controllers, two hot water cylinders and integration into existing radiator circuits. |
| Fuel | The boiler is expected to use around 28 tonnes of wood pellet, producing over 120Mwh of heat per annum. |
| Pellet storage | Internal pellet storage built into plant room shipping container. ETA flex auger extract system |
| Grant /Funding | The installation will receive the remainder of the non domestic RHI which was with the existing installation, this will cover the extra costs of investing in new. |
| Savings /Investment | The care home was already on biomass as a heating system, but this was proving to be unreliable and costly to run. The new system attracts a 5 year warranty and will give many years service. |
| CO2 saving | Compared to the alternative of reverting to oil heating, our wood pellet system reduces CO2 emissions by over 95%, equating to circa 1300 kg CO2 saving per year |
| Commissioned | October 2024 |
Upgrade of unreliable pellet boiler with new ETA system
Project overview.
The Resolve Care group run a series of care homes for young people in the North of England, and have always wanted to embrace renewable energy as part of their Corporate responsibility. Highview House is one of their homes, and a biomass boiler has been installed for the last ten years. Unfortunately, this has proved to be an unreliable and expensive to run system, with no thought to system design and control being made.
Dunster proposed replacing with a new ETA 80kW system, modifying the fuel store to suit and controlling flow rates through the plate heat exchanger to maximise the efficiency and comfort within the home. The plant room was a shipping container, which is not an ideal
option in which to house boiler, buffer and fuel store, but with careful layout planning and location of the mechanical install we have everything in there and accessible for service and repair.
The installation was all very tight, and our in house mini telehandler proved itself invaluable to getting the old boiler out and new boiler in what was a very tight access path.
A fast turnaround was essential and from de-commissioning the old system we have heat back into the building in under three days, which was a huge positive to the residents.
