Heating your water with an electric hot water cylinder
Cylinder Direct can help with repairs and replacements of Low Pressure Hot Water Cylinders and Mains Pressure Hot Water Cylinders
Before considering repairs or a replacement to your electric water heater, we consider what pressure system you’re on – low pressure hot water system or mains pressure.

How do you know if you’re on a Low Pressure System or Mains Pressure?
There are a few ways of figuring this out:
- It’s usually indicated on your hot water cylinder – look for the big white sticker on your cylinder that says “low” or “mains” pressure.
- How old is your house? If it’s pre-1990s, you’re more than likely on low pressure.
- Is there a copper pipe sticking out of your roof, probably above the cylinder? If so, you’re probably on low pressure (this usually gets removed once you switch to mains pressure).
- Turn your hot water on for few seconds, then turn it off. Turn your cold water on for a few seconds, then turn it off. If your cold water has more pressure than the hot, then you’re on a low pressure water system.
- If you haven’t had a good shower in years, you’re probably on low pressure.
What’s the difference between Low Pressure hot water and Mains Pressure hot water?
- Quite simply, the difference is the water pressure coming out of your hot water cylinder.
- Generally, a low pressure system provides water pressure at approximately 75 kpa.
- In contrast, mains pressure hot water cylinders will provide up to 500 kpa, which is a significant difference if you like a good shower or don’t want to have your water running for a long time when washing up.
