Energy derived from fossil fuels will unavoidably become more expensive. Future developments in the price of wood are manageable by comparison.
The price of fossil fuels has jumped in unpredictable leaps, yet constantly increased (something that was considered unlikely ten years ago). This situation will probably not improve in the medium term. The demand, particularly for crude oil, will continue to increase due to the growth of countries such as China and India, and the price inexorably along with it.
Log wood is a source of energy that is comparatively stable in price. With wood, you are heating on the safe side.

Wood Moisture Comparison:
Water content (wet basis) 15%, 20%, 25%, 30%
Wood moisture (dry basis) 18%, 25%, 33%, 43%
Conversion Factors:
1 litre of heating oil generates 2.676 kg CO2
1 litre of heating oil corresponds to 2.5 kg of wood
1 kg wood (w = 20 %) generates 4.0 kWh/kg 1000 Litres of Heating Oil Corresponds to:
Approx 5 - 6 rm hardwood, stacked log wood
Approx 7 - 8 rm softwood, stacked log wood
Approx 10 – 15 srm wood
Explanations and Abbreviations:
1 srm = 1 m3 of poured wood (loose)
1 rm = 1 m3 of stacked split wood (stere)
1 fm = 1 solid metre of wood (without gaps)
Woodviking Logmaster
The JÄSPI reverse combustion boiler is designed for an oil / gas burner or solid fuel and electricity usage. In standard delivery the boiler includes equipment for burning wood and one 6 kW electric heating resistor. Furthermore, both sides (left and right) have a pre-fitted aperture, where a pellet burner can be installed. The Woodviking Logmaster is slightly larger than the Pelletmaster making it more suitable to log burning.
- Can comfortably take 18” (50cm) logs.
- Logmaster has all of the features of the Pelletmaster and can be fitted with a pellet burner, mounted on the side.
- The Logmaster comes with draught regulators as standard.
Bio Triplex
The Triplex has two furnaces that work together or independently. One is for a pellet burner and the other is a down burning log boiler with ceramic grate.
This offers great flexibility for the user, allowing cheaper logs to be used as the primary fuel with the peace of mind that the pellets continue once the logs have burnt down.
- The boiler has all the features of the Woodviking, onboard hot water and domestic hot water coil etc.
