Pellet Boilers for heating and hot water
Wood pellet boilers operate similarly to fossil fuel boilers. When heat is needed, they automatically ignite, feed fuel to the fire, and shut off as necessary. This automation makes them an excellent alternative for those seeking a cost-effective and environmentally friendly option compared to traditional oil, LPG, or electric heating, all while ensuring high comfort levels. They are suitable for a range of applications, from small domestic properties to large commercial facilities.
When choosing a wood pellet boiler, it’s important to consider several key factors:
-
Fuel Storage: Ensure you have adequate space for storing wood pellets, as this will impact your boiler’s efficiency and ease of use.
-
Energy Storage: Consider options for storing excess heat, such as an accumulator tank, to enhance efficiency and provide hot water on demand.
-
Control Systems: Look for advanced control systems that allow for precise temperature regulation and automated operation, ensuring optimal performance and convenience.
Benefits of a pellet burning boiler;
- Simple to operate
- Fully automatic control and feed systems
- Automatic ignition and cleaning
- Eligible for both the Domestic and Non-Domestic Renewable Heat Incentive Schemes
- High density wood pellet requires less storage space than other forms of biomass
- Significant fuel savings over oil, LPG and electricity
- Lambda controllers ensure high real-life efficiencies up to 93%
- Designed for long operational life
- Integrated weather compensation

Pellet Storage
Pellet storage can either be incorporated locally within the boiler, or via a bulk pellet store that is either augered or vacuum transferred to the boiler. Pellets are available in pre-packed bags (normally 15 kg) for ease of handling and convenience, or bulk delivered for those looking for extended periods between refuelling and optimum buying price.
Buffer Tanks/Thermal Stores
Buffer tanks, or thermal stores, are crucial for the efficient operation of all biomass boilers The benefits gained from using an accumulator are substantial. Not only do they reduce fuel consumption they allow accumulated energy to be available immediately, there is no need to light the boiler. This reduces emissions and increases the life span of the boiler. In addition the buffer tank or thermal store allow multiple heat sources to be linked as well as offering your central heating system access to heated hot water
Combustion Control
As with all high efficiency biomass boilers, pellet boilers require clever electronic controllers to ensure the highest efficiencies possible. Typically, pellets are ignited in a combustion chamber where the volatile gases are driven off and gassified by adding secondary air. The controller ensures the precise mix of fuel, primary air, and secondary air at all stages of combustion.
Perfectly regulated with the HDG Control
The new HDG Control is the intelligent control centre for your entire heating system. Whether on the large touchscreen on the boiler or via the app: With HDG Control, you always have absolute control over your heating system.
- Control of combustion and output
