Fix your hot water cylinder today - the right way

There’s often a fix for many parts of hot water cylinders such as valves, thermostats, and elements. Just give us a call, and we’ll check it out to pinpoint exactly what’s going wrong. 

Our Master Plumbers carry a range of parts with them and may be able to remedy the issue on their first visit. 

It’s worth noting that if your cylinder is on the older side, repair might not be the most cost-effective route. And if the cylinder itself is leaking, a replacement might be the only solution. 

But no matter the issue with your hot water system, we’ll provide the reliable and trustworthy advice you need. We take hot water seriously!

The guys at Hot Water Shop changed my leaking low pressure hot water cylinder to a mains hot water cylinder. They were fantastic to deal with. Free quote, turned up on time and house was left clean and tidy with a new mains hot water cylinder. Very easy to deal with. Highly recommend.

Installation of new mains pressure HWC outside. Good price, good workmanship. Friendly and obliging. Happy to come back and tweak the system (temperature and pressure) after installation. Very happy with outcome.

Great team - they removed the existing hot water cylinder and replaced it, connected us to mains, and also replaced the shower mixer for us. Everyone I dealt with was great, and I'd highly recommend them for their reasonable prices and good service.

From start to finish I could not be more happy with my experience with Hot Water Shop. While the pricing was really competitive, it was the fact the whole team were super friendly, professional and helpful, that made them really good to deal with. If you need a plumber, I cant recommend them highly enough, they did a really good job.

Repairs for all kinds of hot water cylinders, hot water systems, and hot water heaters

Our team installs, repairs, upgrades, and replaces all kinds of common and not-so-common hot water solutions.


Our Hot Water Cylinder Services

We start with a thorough assessment to pinpoint the exact issue with your hot water system. We’ve got the experience to find faults quickly, but we never assume what the problem is. Instead, we put the work in to find what’s wrong with (and right for) your individual system.

No hot water in your home? It could be a thermostat issue or faulty element. We’ll find the problem and get that water running hot again.
Hot water leaks lead to wasted water, higher energy bills, and eventually, damage to your home. We’ve seen a few leaks in our time, and pride ourselves on quickly identifying where it’s coming from, and what you can do to fix it.

You don’t need to live with low hot water pressure! Whether it’s a sudden issue, gradual development, or an inherent performance issue, we’ll give you the water pressure you want and deserve.

Older hot water systems sometimes use a header tank – a tank on your rooftop or in your ceiling space that supplies water to the hot water cylinder. So if there’s a problem with your header tank, such as a blockage or malfunctioning ballcock, it can reduce what’s available to your cylinder. Depending on your system’s needs, we can provide repair solutions, or ways to bypass the tank entirely.

Overflows are outlets on the outside of your home designed to relieve pressure from your hot water system as the water heats. Some water coming out is normal, but if it leaks excessively, it could be a sign of a bigger problem like a broken thermostat. We can fix the overflow, but also make sure the entire system is functioning properly.

Frequently asked questions

While we respect the DIY spirit, we don’t recommend replacing any form of water heating yourself. Sometimes the problem can be more complex than it seems, and sadly, home repair work is one of the main causes of water leaks we’ve come across.
Absolutely! We can replace a heating element for a hot water cylinder. Most elements are available off the shelf and we can replace the same day.
We certainly can replace a thermostat on a hot water heater. Like heating elements, thermostats are usually easy to get. You can usually expect a replacement the same day.
We can. We can replace jets, valves, regulators, pigtails, controllers and more on gas califonts and gas bottle stations. Our qualified gas fitters can test, replace, and certify on the spot.
Yes, plastic drain valves (gate valves) can be replaced on water heaters. We recommend checking these now and then to make sure they’re operational and haven’t seized.

For all your hot water cylinder needs.
