Hot water systems are designed to last. That said, some people take routine measures to ensure that their system is always in good working order by routinely replacing it. A hot water replacement might only be needed every 12 to 15 years or so, but it means ensuring your entire system is in good working order all the time. Nevertheless, many other people will only seek a hot water replacement service when their current system starts to develop problems. What are the main signs that a hot water replacement service from your plumber might be a good idea?

• Discolouration

When you turn your hot tap on to run a bath or do the washing up in your kitchen, the water should be transparent. Bear in mind that when water comes out of a tap under high pressure – whether it is hot or cold – it may be opaque for a few seconds until it settles. This is perfectly normal and not a sign you need a hot water replacement installation. However, if muddy looking or rusty coloured water comes from your boiler, then you will need a replacement. Sometimes it is rust that is causing the fault, but it may be that other particles are getting into the system. Either way, failing to act could result in a health hazard.

• Uneven Temperatures

All boilers produce some fluctuation in temperature depending on the pressure of the water – something that has a big impact on combi boilers, for example. However, these differences are not usually detectable without a thermometer. If you notice big swings in the temperature of your hot water, then a hot water replacement may be necessary if the issue cannot be easily resolved. With older systems, it is sometimes more cost-effective to replace everything rather than spend a long time fault-finding only for a similar problem to develop elsewhere down the line.

• Strange Noises

Boilers and hot water tanks make some noises as they are used. The heat that is generated in a hot water system will cause normal expansion and contraction which is usually detectable as creaking sounds. However, if you notice more unusual sounds coming from your hot water system, then a replacement may be needed. Typically, you will notice sounds at odd times or you will hear clicking or knocking noises instead of the more common low-level creaking. Popping or cracking sounds may indicate a catastrophic failure is in the pipeline so act immediately if you hear such symptoms which indicate a wider problem.
