Gas heater
a) round push button for generating the ignition spark (as with the piezo lighter ) on the pilot flame;
b) rectangular off and on buttons, the latter having to be held for a while after ignition until the temperature control on the pilot flame keeps the gas valve open;
c) round thermostat for the gas burner
A gas stove, or gas stove for short, is a room stove (heating stove) operated with gas as fuel .
history
This type of oven has been mentioned in the specialist literature since the turn of the century . Gas stoves used to be widely used as individual heating systems. After the Second World War, they were often used in old buildings, where they could be connected to the existing chimneys. The ovens, which are mostly operated with town or natural gas , were primarily used for brief heating of less used rooms or small rooms such as bathrooms , hallways , kitchens , etc.
species
There were essentially three versions:
- Gas convectors ,
- Gas radiators and
- tiled stoves equipped with gas burners .
In the 21st century, the importance of gas stoves as single heating has declined significantly. In contrast, gas central heating became very important. Here, water is heated in a gas-fired boiler, which heats the radiators of a residential unit ( floor heating ) or an entire building.
The disadvantage of gas stoves is the comparatively high gas consumption, especially when several rooms in a house are to be heated with one stove each. One advantage is that gas stoves (unlike central heating) do not require a power supply and therefore also work in the event of a power failure - or where there is generally no electricity available. If there is a risk of frost, central heating systems must also be kept in operation in buildings that are only occasionally inhabited so that the water in the pipes and radiators does not freeze; this is not necessary with gas stoves. Therefore gas stoves can also be used, for. B. can be used for gazebos or holiday homes, but operation with bottled gas is usually necessary here, as there is usually no connection to the natural gas network. Gas stoves can either be connected to a chimney or have a direct external exhaust that leads to the outside through the wall behind the stove. In this case, the necessary combustion air can also be drawn in from outside.
As a visual design element, there are also gas fireplaces or gas-operated wood - burning stoves , some with imitation wood made of ceramic or visually impressive high flames and recently with radio remote control. Gas fireplaces are particularly common in England and the Benelux countries. They are primarily intended as additional room heating and are usually not allowed to serve as the sole heating source. Thanks to new active exhaust air systems with fans, which allow angled courses up to 20 m in length and have relatively thin cross-sections (10 cm), gas fires can now be placed in many places.
