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.

I worked in property industry for years nationally and used many plumbing services. 1st time used the JT plumbing service and they are very good, easy one of the top favourite I work with in years , from communication to get the job done at the times they promised and at a fair price also. So I commissioned them for a 2nd big job with our water heater, and again, a job well done, no complaints. The current team are great and I will keep come back for their service. I hope they will keep maintaining the current performance level or better.Posted on Google Eric SouchonApril 7, 2026.Trustindex verifies that the original source of the review is Google. Great job, great people and great service - thank you.Posted on Google frank usherwoodMarch 29, 2026.Trustindex verifies that the original source of the review is Google. Running late for a school trip, I noticed a small leak from a fitting on the main pipe. So I gave it a wriggle, and then it was a proper leak. I turned the mains off and rang JT Plumbing while I was on the road. They sorted everything, and the bill was more than fair for the peace of mind I had, knowing it was being sorted. Highly recommended.Posted on Google Toby HawesMarch 20, 2026.Trustindex verifies that the original source of the review is Google. Was recommedned JT Plumbing by a colleague.
