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.

We had a split water pipe up in the roof space that cased good damage over our bathroom. JT Plumbing called in ASAP that day and fixed the pipe for us. We will use these guys/girls for any future plumbing jobs. Thanks again.Posted on Google![]()

JT Plumbing came to my aid at very short notice for a burst water pipe. They fixed it, sorted same night in the weekend at a very reasonable price. The best bit was they trusted me to pay after the completion of the job. Best quality, great service and one I’d definitely use again.Posted on Google![]()

We had a small but unusual job involving replacement of a gas cooktop. We thought it would be only a nuisance job for a plumbing/gas company to do but it was not an issue for JT-PD&G. They had to come twice. On both occasions the guys arrived on time and completed the job promptly. We are happy customers.Posted on Google![]()
