Hot Water Woes: Understanding Your Unvented Water Cylinder

12 May 2021
Unhappy with your hot water? It could be something as simple as getting to know how your unvented cylinder works so that you can adjust it to your needs. In this post, we will explore what you need to know about doing just that.


An unvented water cylinder offers many advantages over older-style vented models. Perhaps the most important is that you can get mains pressure hot water at every tap in the house. Not only that, but you can do so without having to install the cylinder high up in the attic. That offers flexibility of installation, allowing you to use the space within your home more intelligently.

However, if you’re not happy with the pressure at your taps, the problem may not lie with the unvented cylinder. Because it maintains the inlet pressure, any low-flow problems are likely related to the inlet piping or your mains water supply itself, rather than to the cylinder.

Water Temperature

Is your water too hot? Not hot enough? While your unvented water cylinder heats water and then dispenses it when you open the tap, everyone has different preferences when it comes to temperature. Whether you like it hot, hot, hot, or want something a bit cooler (perhaps because of the presence of young children in the home), you can customise the temperature to your preferences.

To change the temperature, simply locate the thermostat on your cylinder. For older models, this will likely be a gauge-style model. However, newer thermostats may have a digital thermostat that can be set with the touch of a button. Simply adjust the thermostat to your desired temperature and then give the system a little time to adjust.

Note: If you have young children in the home, it is very important not to set your thermostat too high. It is very easy for children to be scalded by hot water. If you have questions about setting safe temperature, the experts here at EasyFlow can help.

Not Enough Hot Water

One of the most common complaints when it comes to hot water is that there just doesn’t seem to be enough. Thankfully, this might be an easy problem to overcome. Your unvented water cylinder comes with a programmer that allows you to set the length of time the system heats.

Take time to determine your family’s usage pattern. When is there the most demand for hot water? For most homes, that’s first thing in the morning when everyone is getting ready for work and school, but your schedule may vary.

Once you have determined when you have the most demand for hot water, set the programmer for the right duration. That will ensure that it heats water for longer periods before shutting off, keeping you supplied.

Other Considerations

Modern unvented water cylinders are designed to be hassle-free. That means setting the temperature and programming the length of time it heats are really the only adjustments possible. If you’re struggling to get the right temperature, the right flow of hot water at the taps, or you’re running out of hot water and the programmer isn’t helping, get in touch with the pros at EasyFlow.
