Mains Pressure Cylinder
New homes in New Zealand are mostly built with an equipped mains pressure hot water cylinder, providing high-pressure water as well as fast water heating. Mains pressure can deliver up to 500kPA, which is starkly different from the force delivered by a low or equal pressure cylinder.
Lots of people make the switch from low/equal pressure to mains pressure cylinders for several reasons, although there are advantages to having a low-pressure hot water system as well! In modern households where several people share a home, low-pressure systems can be inconvenient due to how long it can take for water to heat up (and it takes longer the further away the tap or shower is from the cylinder.)
The lower water pressure delivered can also be a pain for anyone who enjoys a powerful shower. People who like a full, hot shower – quickly, want a mains pressure system. The advantages of a low-pressure cylinder are the longevity of them as well as the simplicity, so for a home that only has to cater for one or two people, or as a holiday home, they are perfectly acceptable choices.
