Key Facts

Project Included;

  • Guntamatic 198kW Biocom boiler system including a 3,000 litre thermal store.
  • Distribution pipework including internal connections to heat exchangers.

Fuel Consumption;

54 tonnes of wood chips, per annum. (based on 198kW boiler, in a similar application)

Fuel Cost Saving;

Wood chips; 50-80% vs heating oil.

CO2 Saving;

Up to 96% or 88 tonnes vs heating oil.

RHI Payments;

A project of this size would gain an average of £22,895 every year for 20 years, index linked to inflation.

Total Project Price; £97,000

Payback Period;

4-5 years (combining RHI income & fuel cost saving).

(*Financial information not specific to this project – figures are based on an average of several typical projects of this size. Current information on RHI payments for
guidance only, not to be considered a guarantee).

The System:

  • Guntamatic Powerchip 198kW biomass boiler cascade.
  • Runs on wood chips.
  • Supplies heating and hot water to farm estate.

The Result:

  • Biomass Fuel Cost Saving; 50-80% (wood chips).
  • CO2 Reduced; Up to 96% or 88 tonnes, per annum.
  • Financial Benefit; Fuel cost saving and RHI income to be reinvested to reduce overheads and support future growth of the farm-based business.

“Having experienced a few initial problems relating to recycled and poor quality fuel, Treco fully supported me. We subsequently switched back to virgin, good quality fuel within the G30 fuel standard and the plant is now operating correctly and at its full efficiency.”

Fairclough Hall Farm Estate (Commercial) - Project Background

Fairclough Hall Farm Estate includes a substantial farmhouse residence and estate office units. A former granary barn and outbuildings have now been converted into 11 high specification office rental units and
a cafeteria, with plans to add more.

Although the client still farms the site and adjoining lands, diversification has taken place over a number of years to develop the farm base and its buildings into modern business rental units.

An enviable working environment in stunning rural surroundings, but within easy reach of road networks has been developed. With high specification and comprehensive on site amenities, client businesses have remained on site.

The property and rental units were heated by 8 oil boilers. Our brief was to design, install and maintain a high efficiency, fully automated biomass heating system.

Treco supplied and installed two 99kW Guntamatic Biocom boilers in cascade, with a fuel store, to send 198kW of heat to a 3,000 litre buffer tank. The heat, in the form of hot water, is distributed to each unit by a district heating pump. They have now been adapted by using bespoke  SAV heating and hot water units with individual heat metering. The existing oil boilers have been retained for back up. To date, they have not been required. A second system is now being considered.

Biomass Boiler Installation Diagram

Treco‘s design, installation, commissioning and maintenance service included;

  • Two top-of-the-range 99kW Guntamatic Biocom biomass boilers in cascade.
  • Biomass boiler linked to existing heating and hot water system.
  • 3,000 litre thermal store.
  • 2m agitator and 2.5m auger to enable a large enough fuel store to minimise fills. 
  • Fully automated wood chip fuel delivery system.
  • 4 x Series 7 SAV Consumer interface units.
  • An RHI approved heat meter which records heat use in kWh (on which RHI payments are based) complete with certification.
  • Assistance with RHI application including schematic drawings.
  • Commissioning, programming and end user training.

Renewable Heat Incentive

As well as delivering fuel cost savings of 50-80%, the installation is now accredited for Renewable Heat Incentive (RHI) and will receive payments in excess of £22,895 for the next 20 years.
