Over time, sediment and ‘hard water’ take their toll on pipes and hot water cylinders. Build-up can cause malfunctions and failure of elements, valves and circulation. Normal wear & tear can eventually cause failures too. Only with regular servicing can you prevent major issues.

For uninterrupted supply of hot water, it is recommended to have your system checked, flushed and maintained by a Master Plumber every few years. Book a complete service of your home’s hot water system with JT Plumbing today.

Frequently asked questions

It’s very important that your hot water cylinder is set at the right temperature! A little too hot and your hot water can cause serious burns within seconds. A little too cold and you risk growing dangerous Legionella bacteria in your hot water cylinder. Read more on our post about the subject.

It depends on how your hot water cylinder is behaving. You can often get an idea of what the issue might be from a few simple signs. We’ve written a post about diagnosing the loss of hot water, and you can read it here.

A modern hot water cylinder with insulated pipes can be far more efficient and less costly to run than an older unit. The most efficient kind of hot water heater is a hot water heat pump, which produces more heat energy than the electricity that it uses! There are more simple ways to save money on hot water, and you can read about them here.

Hot water technology has advanced a lot over the past few decades. Unfortunately, if your shower pressure has always been lacking then it’s likely that your hot water cylinder uses old technology. There’s definitely a solution to the problem though: an upgrade! Be sure to read our post about low pressure vs high pressure hot water cylinders.
