The HDG Compact and M Series range of wood chip boilers - modern, highly efficient, clean burning and totally automatic. Suitable for large domestic, commercial and industrial applications, these boilers from HDG are renowned for being the highest quality, most robust and dependable boilers on the market.
Chip boilers have successfully established themselves as a climate-friendly heating alternative in recent years.Wood chip boilers function much like fossil fuel boilers. When heat is required, they will automatically ignite, feed fuel to the fire, and switch off. Their automated nature make them an excellent alternative for those looking for a more cost effective and environmental friendly alternative to traditional oil, LPG, or electrical heating, whilst maintaining the highest comfort levels. Wood chip boilers are generally more suitable for larger domestic and commercial applications where the additional fuel savings compensate for the slightly higher capital cost and greater space and input required for fuel storage. Some models designed for wood chip can also burn wood pellets. |

Wood chip boilers require automatic combustion control to adjust to the varying nature of wood chip as a fuel. The most advanced and efficient boilers encompass a lambda sensor to adjust the primary and secondary air for the highest possible efficiencies. The controller ensures the precise mix of fuel, primary air, and secondary air at all stages of combustion to ensure efficiencies of up to 93%.
Wood chip boilers require larger fuel stores than the equivalent sized wood pellet system. Fuel stores should be sized so as to allow the boiler to run for a minimum of approximately 4 weeks in the coldest weather without the need to replenish the store. A number of methods can be used to fill the fuel store and are dependent upon individual sites and equipment available.
