Facts

Did you know that a standard solar installation can produce up to 60% of your annual hot water needs
The exact distance between Earth and the Sun varies with its position in its orbit, which is elliptical. The average distance (the mean distance) between the Earth and the Sun is about 150 million kilometers (93 million miles).
The average distance from the Earth to the Sun is also called 1 astronomical unit (or AU). This is established as 149, 597, 870.7 kilometers (92,955,887.6 miles).

• Aphelion (when the Earth is the farthest from the Sun) occurs around the first week of July. The distance is about 152 million km (94.4 million miles).
• Perihelion (when the Earth is closest to the Sun) occurs in the first week of January. The distance is about 147 million km (91.3 million miles).

Chip and Pellet Boilers

Heating with wood chips, wood pellets and sawdust/shavings, recovers energy on-site, safeguards local jobs in the surrounding region and offers an additional source of income for land and forest managers. The use of wood reduces our dependence on heating oil and natural gas. The burning of oil also produces higher sulphur dioxide and hydrocarbon emissions than the burning of wood chips. The transportation and storage of wood chips poses no threat to the environment. Heating with wood chips is ecologically responsible, as it has a virtually closed CO2 cycle.

Wood chips are made from whole trees, branch wood or coppice products which have been mechanically shredded by a chipping machine. Ideally the wood needs to have been air-dried before chipping, or the chips dried before burning.

Shavings and Sawdust
Waste wood from manufacturing which has no addatives such as wood planings and sawdust can be a perfect way to use a waste wood for heating.

Wood Pellets
The compact range can burn wood pellets ether as a dedicated fuel source or as an alternative
