GASIFICATION BOILERS

The KK wood gasification boilers are designed to be installed in an outbuilding or utility room. They have large wood fire chambers to let you easily heat your house and domestic hot water.

Essentially, after starting a kindling fire and producing a bed of hot coals, you then fill the firebox up with logs and then walk away – the gasification boiler then burns for three to four hours. Gasifying boilers are batch burners meaning that you load them right up, burn them hard, let them burn down, and then reload if needed. This is a very efficient way of burning wood which produces low levels of emissions.

The heat from the wood is often stored in a thermal storage for use as and when needed, although you can connect a gasification boiler directly to a standard heating system.

A log boiler used with a thermal storage tank gives you the ability to decide when and how you want the heat in your home, independent of there being an active fire in the boiler.

Running your whole house with a log boiler does mean using a fair bit of wood – we would recommend these boilers to people who have sufficient room to store a decent amount of firewood, ideally with some storage in the boiler room itself for simplicity and to further dry the wood.

Kroll’s KK series wood boiler supports all kinds of heating systems and is highly adaptable. These boilers are durable and long-lasting. The burning process is clean and requires little labour from your side. The boilers make you more energy-independent and are highly time-saving as well.
