Project included

  • Guntamatic Biocom 100kW biomass boiler
  • Flues and thermal store
  • Runs on wood pellets
  • Heats working country estate, farm and holiday lets

Fuel consumption

Approximately 16 tonnes of wood pellets per annum

Fuel cost saving

  • Wood pellets: 20%-40% vs oil
  • Grain: 60 to 80% vs oil

Approximately 22 tonnes vs heating oil

RHI payments

A project of this size would gain upwards of £11,000 every year for 20 years, index linked to inflation.

Total project cost

£48,000

ROI

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

The Guntamatic Biocom boiler’s touch screen control panel allows us to switch between fuel types at the touch of a button, which gives us fuel flexibility and future fuel security.  It just works away and sometimes I could easily forget the boiler was there at all!

Glenn Anderson, Dillington Hall Estate

Overview

Dillington Hall Estate is comprised of a manor house, pick your own fruit farm, keeper’s lodge and holiday lets. The landscape is varied, with a mix of arable land, small woodlands, pockets of grassland and small river valleys. It is popular with walkers as well as with large flocks of finches and other birds.

The challenge

The Estate’s brief to Treco was for the design, installation and maintenance of a low carbon, sustainable heating solution to replace the aging and expensive oil heating system. The solution would need to be self-cleaning and de-ashing and have the ability to run on wood pellets and grain.

It would have to be as automated as possible and supply the total heating and hot water needs of the manor house, pick your own fruit farm, keeper’s lodge and holiday cottages.

Our custom solution

The client converted an existing outbuilding into a boiler room and fuel store. Treco supplied and installed a top-of-the-range, fully automated, 100kW Guntamatic Biocom biomass boiler system. We also supplied a 2,000 litre buffer tank and 3.5 metre discharge auger.

A stainless steel liner was fitted, along with a ceramic flue, to enable the boiler to burn grain effectively at times when this alternative fuel was available.

Thermostats allow output to be closely monitored via an ECU and emissions are measured by the lambda probe in the flue.  An auger sifts the ash generated from the grate into a removable container.

The incentive

The installation is now accredited into the Renewable Heat Incentive and the client is now receiving payments of approximately £11,000 per annum. These payments, when combined with the fuel cost savings of 20-40% with wood pellets make the project both sustainable and financially viable.
