Central Heating Boilers Fuelled by Wood Pellets
Heating with wood pellets does not contribute to climate change. Wood pellets are regarded as a carbon neutral energy source. When pellets are burnt they release solar energy absorbed during the trees growth. The CO2 released in this process is equal to the CO2 absorbed during the trees growth. In addition, localised production of wood pellets dramatically reduces transport related emissions. Wood pellets not only save energy in terms of manufacturing and delivery, but also create local employment opportunities. They are an important contribution to a sustainable future for our children.
Pellets are made of 100% natural wood. Shavings and sawdust are compressed under high pressure and pressed into small cylindrical rolls and held together by lignin, contained naturally in the wood. This results in a clean, convenient fuel with a high calorific value and very low ash content (0.2%). Every year, more wood is renewed than is consumed. All of these facts are what makes the most convenient of all wood fuels such an interesting alternative in terms of both ecology and economy.

The advanced combustion technology of HDG pellet boilers are perfectly designed to burn pellets as a fuel, resulting in very low emission values. Extremely high efficiency levels are also achieved through the combustion of this environmentally friendly fuel.
Optimised combustion technology results in low pellet consumption. An advanced thermostat controls the boiler temperature ensuring that only the required amount of heat is produced.
The HDG Pellet boilers have been subjected to strict in-house and independent safety tests. The cellular wheel sluice reliably prevents back-burn and the escape of low temperature gas. This sluice wheel, combined with an integrated water extinguishing system provides total safety.
Features such as automatic transport of the pellets to the combustion chamber, automatic ignition, self activated cleaning and large ash container, combine to provide maximum convenience automatically controlled by the HDG Pelletronic boiler control.
The Mechanical Integrity of the HDG Pellet Boilers
The engineering innovations of the HDG Pelletmaster for maximum quality and reliability.
Automatic cleaning of the heat exchanger surfaces.
Tried and tested step grate technology prevents the formation of slag. The grate movement provides for automatic ash clearing into a removable container.
Automatic ignition via hot air blowers provides for an efficient, short ignition phase and fast heating up to the operating temperature.
The pellet management system has been designed to ensure minimum wear and energy expenditure.
Unique combustion and performance control due to the combination of combustion chamber temperature. sensor and Lambda sensor, giving a system that is emission and performance co-ordinated
The Lambda sensor is mounted in a protected position, for the longest life possible.
A precision designed cellular wheel sluice, together with existing pressure compensation reliably prevents back-burn and escape of low-temperature gas.
