Case Study 1 – The Hurst, Craven Arms, Shropshire

GSHP and solar thermal retrospective RHI application (Completed June 2015)

The Hurst is a writers’ retreat located in the beautiful Shropshire countryside. As the building is not attached to the gas grid, the team had installed a ground source heat pump in conjunction with a small solar thermal array. Infinitas Design was approached to undertake the RHI application for both systems as neither had been attempted during the original installs. Infinitas Design worked closely with The Hurst team and the original installers to retrospectively gather photographs and documentation enabling successful approval on to the scheme. Gabriella Blandy, Associate Director for Arvon, said:

the hurst“Laura has carried out two RHI applications for a Solar Thermal and Ground Source Heat Pump system for Arvon. Her dedication to the task has been commendable. She is prompt to answer emails, efficient and very positive. Throughout the process, I have always felt that the claim was in safe hands. I would certainly recommend Laura to anyone wishing to submit an RHI application.” – Gabriela Blandy – Assistant Centre Director

Case Study 2 – Dundee & Angus College

Infinitas Design Ltd was engaged by Dundee and Angus College to investigate an inoperative biomass boiler at its Arbroath campus. The site also used 25 year old gas boilers to generate space heating and hot water.

Angus College Infinitas-Design Biomass installation ScotlandAfter assessing the existing heat generation system, we suggested the decommissioning and removal of the existing biomass and gas boilers and the installation of a new biomass boiler system to serve the existing college buildings as well as connecting two other plant rooms on the college campus to provide additional and backup heat. The other plant rooms were also using gas boilers for heat.

The strip out of the old biomass boiler and gas boilers took place over Summer & Autumn 2016 with the new 800 kW boilers, 15,000l buffer vessels and pumps being installed in November 2016. The fuel store was also modified to accept a greater amount of wood chip with new trough delivery system. The remote plant rooms were connected to the biomass boiler plant room by roof-mounted external pipework.

Infinitas Design provided the full detailed design including plant room layout, hydraulic schematics pics and tender specifications. We also supported the college throughout the installation process with any technical queries and working with suppliers.

We are also undertaking the RHI application now that commissioning has taken place.3D model of new biomass boiler plane room Dundee & Angus College Scotland - Infinitas-Design


Non-Domestic Renewable Heat Incentive Applications

The non-domestic RHI is a government scheme intended to increase the uptake of renewable heat projects in the UK. It provides a tariff for heat generation from biomass boilers, heat pumps, biogas boilers and biomethane, which are known as eligible technologies.

The current and historic non-domestic RHI tariffs can be seen in the chart below. Once approved, the scheme pays out on a quarterly basis and payments are guaranteed for 20 years. You are paid on the amount of heat you produce each quarter.

As the scheme is quite technical, Infinitas Design Ltd can take on the application on your behalf. We will undertake every aspect of the application and will support you right through to application approval:

  • Site visit
  • Document collection & photos
  • RHI heat loss assessment (HLA)
  • RHI compliant schematic
  • Letter of Authorisation

  • Independent Metering Reports
  • Compliant heat meter advice
  • Application completion and submission
  • All Ofgem queries during approval process
  • Seasonal Performance Factor calculation for heat pump projects

We are also happy to pick up half-finished RHI applications or just one or two of the aspects above to help you get to RHI approval.
