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.

Does your hot water cylinder need replacing?

We take the time to find where any leak or problem might be coming from, so you get the right recommendations for your needs. Of course, a replacement isn’t always necessary. That’s why we’re the best people to call: we also handle all kinds of hot water cylinder repairs.


Four signs your hot water cylinder might be due for replacement:

It may sound obvious, but it isn’t always easy to spot! Mould on timber near the cylinder or rust starting to show at the base is a sure sign of a slow leak.
Most cylinders have a 5-10 year warranty, but you should be able to expect 15+ years from it. Check the badge on your cylinder. If it’s getting on in years, consider replacement.
Crackling, popping, boiling or hissing noises are a sign of a failing hot water system. It doesn’t always mean you need a replacement, but it’s worth getting checked out by a professional ASAP.

A complete lack of hot water can quite often be fixed by replacing faulty parts. But on older units, it can be a sign of further failures to follow. Before wasting money on repair after repair, we’ll give you replacement or upgrade options to consider.
