Fuel to create heat Batteries can't store enough energy LPG is readily available LPG is cheap LPG is safe LPG is clean

What is LPG? Liquified Petroleum Gas Butane Odourless, colourless, tasteless Butane has higher energy density Butane boils at 2 deg C Butane is stored as liquid at 28 PSI Expands by 233 times when released to air

What is LPG? Propane Odourless, colourless, tasteless Propane has a slightly lower energy density Propane boils at -42 deg C Propane is stored as liquid at 100 PSI Expands by 330 times when released to air

LPG can generate

Exchange or refillable?

Exchange cylinders Expensive. 6kg (12 litres approx) for £20+ You never own the cylinder Not available abroad Need two cylinders Heavy to handle when changing cylinders Convenient?

Refillables You own the cylinder Cheap to refill 6kg (12 litres approx) £7.60 Never need to run out No heavy lifting Top up at any time Available across Europe Most people only need one cylinder Expensive initially?

Autogas and fridges LPG is dirty and causes fridge burners to soot up FALSE, propane is propane. 3-way fridges need regular servicing TRUE, all gas-fuelled fridges WILL soot up sooner or later Fridges are NOT generally serviced as part of a habitation inspection
