CO2 Saving

  • Up to 96% or 88 tonnes vs heating oil. (Source: Biomass Energy Centre)

RHI Payments

  • A project of this size would gain an approximately £21,854 every year for 20 years, index linked to inflation

Total Project Price

  • £110,000

ROI

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

* To protect client confidentiality, figures are based on an average of several typical projects of this size and all financial information are not specific to this project. Current information on RHI payments is for guidance only, not to be considered a guarantee.

The System:

  • Guntamatic Biocom 198kW biomass boiler cascade.
  • Runs on wood pellets.
  • Replaces oil heating system.
  • Supplies heating and hot water to 21 bed hotel.

The Result:

  • Biomass Fuel Cost Saving: 20%-40% (wood pellets). (Source: Biomass Energy Centre)
  • CO2 Reduced: Up to 96% or 88 tonnes, per annum. (Source: Biomass Energy Centre)
  • RHI Payments: A project of this size would gain an approximately £21,854 every year for 20 years, index linked to inflation.
  • Financial Benefit: Fuel cost saving and RHI income to be reinvested to reduce overheads and support future growth of the farm-based business.

This is the second biomass boiler heating system we have purchased from Treco. As well as a well designed system, appropriate to our needs, we have always found Treco’s project management to be excellent.

Friar’s Carse Hotel - Project Background

Friars Carse Hotel Dumfries

Overview

Friars Carse is a 19th Century country house hotel. It has 21 bedrooms and 3 self catering cottages set in a 45 acre estate with its own woodlands. The original ‘Frierskerse’ was established as a friary back in the 13th century, close to today’s ‘Friars Carse’. The hotel is licensed for weddings and also as a venue for corporate functions.

The Challenge

Having successfully managed a previous installation for this client, Treco were invited to quote for a second system. The brief to Treco was for the design, installation and maintenance of a highly efficient and fully automated biomass heating system.

It would need to run on wood pellets and supply the hotel’s total heating and hot water needs. The biomass boilers would need to fit into the basement, replacing the existing and inefficient oil fired boilers.

Project Summary

Treco supplied and installed two 99kW Guntamatic Biocom biomass boilers. The boilers were installed in cascade, complete with two 1,500 litre buffer tanks and fuel store.

*The client was responsible for the construction of the boiler house and fuel store.

Our Custom Solution

Treco installed and commissioned the biomass boiler, working with the client’s heating engineer to connect to the current system.

  • Two top-of-the-range 99kW Guntamatic Biocom biomass boilers in cascade.
  • Biomass boiler linked to existing heating and hot water system.
  • 2 x 1,500 litre thermal stores.
  • 4m agitator and 4m auger to enable a large fuel store to minimise fills.
  • Fully automated fuel delivery system.
  • High efficiency, low energy modulating main system pump.
  • 1 x class 2 RHI eligible ultrasonic heat meters complete with certification.
  • Consumer Interface Unit and heat exchanger assemblies.
  • Full assistance with RHI application including schematic drawings.
  • Commissioning, programming and end user training.

The Incentive

The significant biomass fuel cost savings of 20%-40% when using wood pellets and the CO2 reduction of up to 96% or 88 tonnes, per annum compared to heating oil (according to the Biomass Energy Centre),makes this a valuable investment.

In addition, Friars Carse Hotel would also receive a significant financial benefit in the form of Renewable Heat Incentive (RHI). A project of this size would gain an approximately £21,854 every year for 20 years, index linked to inflation.

The 20 years of RHI payments combined with the fuel cost savings make this project both sustainable and financially viable. This also means that it will only take about four to five years before they have fully accrued the capital cost.
