Efficiency

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. 

Emissions

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. Emissions from older heating systems, even when they are running without any problems, do not compare well to the emission levels which are achievable with the latest equipment. 

Energy balance

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 loss

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.

Energy resources

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.

Energy source

Fuel oil, bio-oil, natural gas, LPG, and biogas are used as fuels. Their energy content is released during combustion (fuel).

Evaporator

A heat exchanger inside a heat pump. It evaporates a refrigerant by removing energy from the heat source.

Expansion valve

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.
