The Finches, Warwickshire
THE OBJECTIVE
The task was to find the most energy efficient heating system for the detached dormer bungalow property in the Warwickshire countryside. The property currently runs on oil, so the new heating system needs to significantly reduce the heating fuel costs. Not only does the new heating system need to heat the bungalow but also the extension and the swimming at the back.
THE ACTIONS
- Determine that Biomass is appropriate for the property
- Calculate the new heating and hot water demand taking the extension & swimming pool into consideration
- New underfloor heating system to be laid throughout the bungalow and extension.
- Survey, design and install new Biomass Boiler, district heating pipework and plant room for system
- Complete groundwork’s for district heating pipework, base for plant room and construction of a brick built building to house the new system, buffer tank and day hopper.
THE BIOMASS SYSTEM
JD Energy Services Ltd made the decision to replace the old oil heating system with an efficient wood pellet biomass system. They explored all the other possible options with air source and ground source heat pumps, but it was ultimately a biomass boiler that would fulfil the brief more efficiently. As there was no existing outside boiler room available, one had to be constructed. The intention was to have the boiler and the 1000 Litre Buffer Tank close to together inside this purpose built unit, with the 2 tonne Silo adjacent outside connected by a vacuum delivery unit directly into the boilers day hopper.
THE CONCLUSION
The completed installation will see the client save on annual running costs, even with the addition of heating the swimming pool. These savings will be in the region of 40% compared to the previous costs of the old oil boiler. On top of these savings; as the client has applied for the Domestic RHI (Renewable Heat Incentive), they can expect their investment to be paid back within 7 years with these annual payments.
