The difference between the energy supplied and the energy extracted (used). The Efficiency of heating systems is increased by lower flue gas temperatures and lower flow and return temperatures.
Collective term for environmentally damaging Pollutants , which through continual advances in burner technology – a field in which Weishaupt is the world's market leader – are being reduced to a minimum. Nitrogen oxide Emissions in particular (one of the causes of acid rain) have been drastically reduced in recent years.
Consideration of the energy supplied in comparison/proportion to the energy extracted and used. This enables a statement on the economic benefit to be made.
Energy which is lost. It is the difference between the energy supplied and the energy extracted (used). Modern heating systems from Weishaupt reduce energy losses to a minimum by means of efficient heat exchangers and excellent heat insulation.
A distinction is made between finite energy sources, such as oil or gas, which are only available to us in limited quantities and should therefore be used extremely sparingly, and Renewable energy sources, such as solar, wind, or water power. Despite much progress, and taking even a long-term view, these renewable resources will only be able to meet a small proportion of our energy requirements in an economically justifiable way.
A Heat exchanger inside a heat pump. It evaporates a Refrigerant by removing energy from the heat source.
The volume of a liquid expands as its temperature increases and reduces as its temperature decreases. Consequently, the pressure of an enclosed liquid can increase sharply, even with only a small increase in temperature. Without protective measures, such as an Expansion tank , the increase in pressure can lead to the destruction of pipes and other components.
A component within a heat pump. The Expansion valve reduces the pressure and thus the temperature of a Refrigerant , so that it can subsequently absorb heat in the Evaporator . It also controls the flow rate, so that only as much Refrigerant as can be vaporised is passed to the Evaporator .
