Wood boiler - efficient heating with wood as fuel

A wood bo iler is a reliable and cost-effective solution for those who want to heat their home with wood instead of electricity, oil or pellets. With a wood-burning boiler, you get the opportunity to burn a renewable fuel and use a water-based heating system to spread the heat throughout the house. At Ulma, you will find wood boilers that are suitable for both small and large properties, with high efficiency and durable construction.

How does a wood boiler work?

A wood boiler works by burning wood in a combustion chamber, where the heat is transferred to water that circulates in the house's radiator system. The heat can also be stored in an accumulator tank to even out the temperature and reduce the need for frequent firing. This way you can fire when it suits you best and still have access to heat and hot water throughout the day.

Advantages of wood burning stoves

• Cost-effective: Firewood is often cheaper than other fuels, especially if you have access to your own forest or a local wood supplier.
• Independent: You will be less dependent on electricity prices and district heating contracts.
• Environmentally friendly: Firewood is a renewable biofuel that does not add new carbon dioxide to the atmosphere.
• High output: A wood boiler can provide sufficient heat for both heating and hot water in large houses.

Disadvantages of wood boilers

• Manual handling: You need to load wood and light the fire manually.
• Storage space: Firewood requires dry and spacious storage to work optimally.
• Ash removal: The boiler must be emptied of ash regularly.

Wood boiler with storage tank - a smart combination

By combining your wood-burning stove with an accumulator tank, you can store excess heat and reduce the number of times you need to burn. The accumulator tank acts as a heat store, making the system more energy efficient and even out the heat over time. This means you can fire up once in the morning and still have hot water and heat throughout the day. At Ulma, we offer complete system solutions where the wood boiler and storage tank work in perfect harmony.

Wood or pellet boiler - what should I choose?

Both wood and pellet boilers are good options if you want to burn biofuel and use a hydronic heating system. The difference lies mainly in how automated the system is. A pellet boiler feeds pellets automatically and requires less work in everyday life, while a wood boiler requires you to add wood and light the fire yourself. If you prioritize low fuel costs and have access to cheap wood, the wood boiler may be the most economical option. If you want a more self-sufficient system, the pellet boiler is a simpler choice.

How to choose the right wood boiler

When choosing a wood-burning boiler, it's important to consider how much heat your house needs, how often you want to burn it and whether you have the option of installing an accumulator tank. At Ulma, we are happy to help you dimension the right output of the boiler and choose a model that suits your needs and conditions. We offer both traditional wood boilers and modern gas boilers that can be combined with solar heating or other energy sources.
