135 litres is the small-house size: a unit, a one or two person household, or an older home replacing a like-for-like cylinder. It is also the size with the widest spread of shapes, from 935 mm stubby units to slimlines nearly 1.4 m tall. Here is every 135 litre class cylinder we sell.

How heavy is a 135 litre cylinder?
Thermann list their 135L at 50 kg empty, about 182 kg once it holds 132 litres of water.
How long does a 135L cylinder take to heat up?
About 7.8 kWh from 15°C to 65°C: 2.6 h with a 3 kW element, 3.9 h with the 2 kW element in the copper low pressure models. See how long a cylinder takes to heat.
Is 135 litres enough?
135 litres usually suits 1 to 2 people. If the hot runs out mid-shower now, go up a size rather than replacing like for like: see what size cylinder do I need.
Thermann 160L: more water in nearly the same space
The Thermann 160L holds 163 litres in 530 x 1315 mm, only 17 mm taller and 40 mm wider than the Thermann 135L, with a 3.6 kW element. It is $1,210. If the cupboard has the width, it is the easy way to get more hot water from the same spot.
