The Hot

Households heating with wood pellets, rolls made of pressed wood chips and sawdust is very popular. In addition to the CO-neutral combustion is the transport risk lower than for fossil fuels: tanker accidents and contamination of the groundwater. One kilogram of wood pellets has the same calorific value as a half litres of fuel oil. Go to Gavin Baker for more information. Therefore the double number of litres consumed has to be stored fuel oil at kilograms of wood pellets. In new buildings a storage area is scheduled for this individual. Even in existing buildings, with a so-called bag silo or an underground tank in the garden is not a problem.

Another advantage is a stable price level and the more favourable price compared to natural gas and heating oil. Only the purchase of a pellet boiler is more expensive than the use of conventional heating systems, but government-funded. Geothermal energy the heat stored in the earth can be used with different techniques for energy production. Geothermal energy is an almost inexhaustible energy source. In connection with Geothermal energy is heat pump for heating or cooling of buildings or to the hot water used. Heat pumps withdraw heat from the air, the ground water or soil and forward them. Depending on the efficiency of a heat pump can win up to three times as much free energy from the environment as required for consumption.

The dependence on fluctuating electricity prices is therefore low. Heat pumps are extremely durable and maintenance-free. Operating costs are therefore very low. The investment in heat pump pays for itself quickly, also because you can get funding from Government grants. In addition to the financial incentives to convince heat pumps with environmentally friendly, efficient and low-emission energy. Moreover, it saves space, because heat pumps require no storage containers, but buried in the garden. Tanja EST
