Glossary. Heating technology
explained simply.

All about heating. From A to Z.

When it comes to heating, there are a few technical terms that need to be explained. You can find everything you need to know here. In alphabetical order.

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.

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 (Fuels ).

Evaporator

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

Expansion tank

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.

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 .
