Types of wood heating in comparison

Heating with wood is an ecological - and also inexpensive - compared to fossil fuels. Timber heating is not the same as wood heating: which different options are available for heating wood, and where the advantages and disadvantages lie, this article shows.

Raw material wood

Wood is a renewable resource that is usually available at low cost. Due to the high availability of wood, price increases are also unlikely, which makes wood heating a fairly predictable thing.

Heating with wood is also practically carbon neutral because it is a closed carbon dioxide cycle. In which form one burns wood, but can be different.

Classic stove

The stove is a very inexpensive, but not very convenient form of wood heating for individual rooms. It is now used practically only as additional heating with a high feel-good and decorative factor.

For the stove high quality wood is necessary, preferably beech wood. Too soft wood burns off too quickly and gives off too little heat.

An interesting option are the classic Bullerjan ovens, which can also be equipped with a water bag, and so can serve as a water heater in winter. Several rooms can be heated with hot water via pipelines, and mini-central heating is created for smaller areas.


Tiled stoves are characterized mainly by their heat storage capacity. For high-quality, well-planned tiled stoves you can often have enough residual heat for two days after heating. The cost of building a high-quality tiled stove, however, are extremely high, so they are only used by lovers as a heater for smaller houses.

In individual cases, they can even cover more than one floor, and even provide relatively large areas with radiant heat (similar to infrared heating).

Pellet boilers and woodchip heaters

Pellets are pressed very high density wood waste. This brings a very high energy density and high efficiency in a pellet heating with it and at the same time ensures very low ash.

Log wood boilers can also be retrofitted for operation with pellets, but this option is not always an ideal solution.

For the pellets, a corresponding storage room must be available, and an automatic feeder must be installed in the oven. This does not need to be refilled with pellet heaters and the oven can also run automatically.

A disadvantage of pellets is that it is an industrially produced product which is thus subject to market and price fluctuations.

Wood chips are the cheaper alternative here. They are made with very little effort from wood waste, are usually cheaper and also more stable in price, but also produce more ash than pellets.

wood gasification

Wood gasifiers are log wood boilers in which the wood and the resulting wood gas are burned separately from each other. This results in a 50 percent higher efficiency compared to the normal log boiler, but wood gasifiers are more expensive to buy.
