High power, energy saving commercial biomass boilers and ground source heat pumps

Dunster’s renewable heating solutions are a long-term, low-cost and high return investment. Commercial spaces that are either off the gas grid or use oil as their primary source of heat, with a high demand for heat in particular will benefit from our heating systems.

Ground Source Heat Pumps (GSHP)

GSHPs are extremely efficient in space heating and producing hot-water and cooling services for your commercial needs. They use minimal energy, have a long lifetime and need little maintenance.

From large scale agricultural milk cooling plants to commercial buildings and social housing schemes, the heat pumps offer a wide operating range from -25°C to +85°C and a plant size from 75kW up to 1.5MW with full modulation. Dunster offers a full design service and can guide you on the right scheme for your commercial development.

The CRC Energy Efficiency Scheme

The CRC Energy Efficiency Scheme is a mandatory carbon emissions reporting scheme that covers large public and private sector businesses in the UK. It targets any businesses that are using more than 6,000 MWh of electricity a year; the business must have at least one half-hourly meter installed.

The scheme requires businesses to purchase carbon credits for every tonne of carbon they emit as per their reported usage of gas and electricity. By choosing Dunster you can reduce your business’s energy usage and therefore the amount of credits you have to purchase. It’s a win-win.


The Energy Saving Opportunity Scheme (ESOS) regulation requires large companies to conduct a mandatory energy audit every 4 years. You are categorised as a ‘large organisation’ if you fall within certain parameters.

Failure to comply with ESOS can lead to a fine of up to £50,000 and public disclosure of non-compliance.

Biomass can provide a solution to issues highlighted in the energy audits and can demonstrate steps being taken by the business to reduce carbon based energy.
