Hot Water Problems

Hot water is one of today’s modern essentials in homes and businesses. Usually, it is delivered by means of gas or electricity and boilers, hot water cylinders and immersion heaters are just part of the critical infrastructure involved in the provision of your supply. Therefore, hot water problems are a huge inconvenience. In the worst-case scenario, they can even be the root of risks and hazards to health due to the inability to keep yourself and your property warm, clean and sanitised. Fortunately, professional plumbers like No1PHD are here to help solve such problems fast before they really start to have a negative effect on daily life. Our fast, efficient and effective repair service for hot water problems gets to the root of the matter for a permanent fix.

Boiler problems

In most homes and businesses, hot water is delivered via a boiler that runs on gas or electricity. Boilers are complex and need regular maintenance and servicing to stay safe and operational. A lack of maintenance can lead to hot water problems. However, No1PHD can come to your property to regularly service your boiler to keep it error-free and delivering both heating and hot water to your home. If you find that you are experiencing hot water problems, this could be down to a faulty component or even an incorrect setting on your boiler. In all cases, it is essential to ask the experts to step in rather than tamper with your boiler if you are not qualified to do so. As certified gas and electrical engineers, we can come out to look at the problem very quickly and provide a free quotation to get the job done.

Hot water cylinder issues

Some homes and businesses have their hot water delivered from a hot water cylinder. These can sometimes go wrong, leading to hot water problems. The range of issues includes:

  • A faulty thermostat
  • A faulty valve
  • Incorrect water pressure
  • An electrical fault like a broken fuse

Of course, these are just some of the problems we regularly encounter when it comes to hot water cylinders. We really need to attend your property to precisely diagnose the fault.


Leaking pipework is a plumbing issue that can lead to hot water problems. Leaks can develop in pipework, from boilers and hot water cylinders. Essentially, leaks cause a loss of pressure, which means the hot water system cannot function properly and will start to play up. You might find that you have no hot water at all. On the other hand, water might be too cold, too hot or just a trickle from the tap. In all scenarios, No1PHD’s technicians know just what to look for to resolve the fault. We can repair all leaks and various parts, fixtures and fittings. In extreme cases, we can also emergency replace your boiler or hot water system. Most of all, we work safely and always isolate the critical supply as required, whether water, electricity or gas.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
