If they ban gas boilers what will all those now unused flames do?

“The flame that freezes” said Mr Therm in the Gas Council adverts.

Yes my family had a gas fridge in the 1960s. Yes it was fun. The fridge was situated rather near a door and sometimes the flame would blow out. Out first indication that something was wrong was usually a smell of gas and the fridge loosing its cool. 

Sometimes the fridge would loose its cool, even with the flame burning. I heard advice from somewhere that one could cure this by turning the fridge upside-down for a day or two. I tried it and yes it worked - I never really figured out why. 

Thank goodness we have moved on. I think Electrolux was the main manufacturer behind this type of fridge, though Electrolux nowadays makes fridges using the compressor principle, just like everyone else. 

The flame that freezes.

Even today, the ones we take on camp (burning propane) are the same ammonia cycle- using the fact that you can “pump” ammonia through a water column by dissolving it in cold water, making a low pressure, and boil it out of hot water making the high pressure.

In an atmosphere of hydrogen at high pressure (10-15atm) we can get ammonia cooling down to perhaps -20C.

IF water gets stuck in the coils so the ammonia pump does not work, then inverting or laying on its side can help unbung it.

My mother still has her warm-air gas heating system, Lennox built, circa 1965. Complete with pilot light.

Gas fridges still common in caravans & motorhomes. You should get out more, folks!
