How big does an LPG tank have to be?

Unlike heating oil tanks, LPG tanks are filled several times a year, since a gas tank big enough to meet your entire annual needs would be hugely expensive. Depending on the precise geographical location, you can expect the tank to be filled six to eight times a year.

For smaller and medium-sized residential properties a 5 m3 tank is normally installed. Industrial and commercial users may use larger tanks (up to 150 m3, occasionally even larger).
