Key Facts

Project Included

  • Guntamatic 100kW Powerchip boiler system including flue and thermal store.
  • All aspects of district heating scheme.

Client Managed;

  • Distribution pipework including internal connections to heat exchangers.
  • Building a high specification, custom-built boiler house & fuel store.

Fuel Consumption;

  • 37 tonnes of wood chips & miscanthus, per annum. (Based on 100kW boiler, in a similar application)

Fuel Cost Saving;

  • Miscanthus & Wood Chips Up to 80% vs heating oil. (Source; Biomass Energy Centre)

CO2 Saving;

  • Up to 98% or 44 tonnes vs heating oil. (Source; Biomass Energy Centre)

RHI Payments;

  • A project of this size would gain upwards of £11,038 every year for 20 years, index linked to inflation.

Payback Period;

  • 5-6 years. (Combining RHI income & fuel cost saving)

Total Project Price;

  • £75,000.

The System:

  • Guntamatic Powerchip 100kW biomass boiler.
  • Replaces six oil boilers and heats four separate buildings in a district heating scheme.
  • Runs on wood chips, sourced locally.
  • Is accredited into the Renewable Heat Incentive (RHI) and is now receiving payments.

The Result:

(Compared to heating oil. Source, Biomass Energy Centre)

  • Biomass Fuel Cost Saving; 50-80%. (Source; Biomass Energy Centre)
  • CO2 Reduced; Up to 96% or 44 tonnes, per annum. (Source; Biomass Energy Centre)
  • RHI Payments; A project of this size would gain upwards of £11,038 every year for 20 years, index linked to inflation.
  • Financial Benefit; RHI payments and fuel cost saving make the project both sustainable and financially viable.

“Treco’s support throughout the project was excellent. They gave us great advice, project management and support from the initial design phase to installation. They even managed our RHI application for us! Now that we are happy with the system, we plan to install Guntamatic systems at 2 additional sites.”

West Heanton Care Home - Project Background

West Heanton Ltd. is a family-run care home and domiciliary care agency in rural North Devon. The care home was converted from a beautiful old farm house. It has grown and expanded to provide care for twenty three residents as well as seven sheltered living appartments and care in people’s own homes.

The Requirement

The primary requirements for this care home provider were high levels of reliable, constant heat and resident comfort. The six existing oil boilers needed to be replaced with a single biomass boiler, providing heating and hot water to four separate buildings. Treco were tasked with designing and installing a biomass system, working in partnership with the care home’s heating engineer.

Complete Biomass District Heating Package

Treco supplied and installed a single 100kW Guntamatic Powerchip biomass boiler feeding a district heating scheme. The boiler and fuel store were installed in a converted barn with all of the buildings linked using insulated underground pipe. All fuel is sourced locally and processed directly into the fuel store.

Project Summary

The client was responsible for the construction of the boiler house and fuel store. Treco installed and commissioned the biomass boiler, working with the care home’s heating engineer to connect to the current system.

The District Heating Scheme Included;

  • A top of the range 100kW Guntamatic Powerchip biomass boiler
  • A fully automated fuel delivery system.
  • 5m agitator allowing 75m3 of fuel storage to minimise the number of fills per year.
  • 3.75m auger.
  • A 3,000 litre thermal store.
  • High efficiency, low energy modulating main system pump.
  • 160m of twin underground pre-insulated pipe.
  • 2 x class 2 RHI eligible ultrasonic heat meters complete with certification.
  • 5 heat exchanger assemblies.
  • Full assistance with RHI application including schematic drawings.
  • Commissioning, programming and end user training.
