How To Tell If It’s Time To Replace Your Water Heating System?

For most of us, on-demand access to hot water isn’t optional.
We count on our water heaters or boilers to get us through every shower and sink full of dishes. But even top-of-the-range water heaters aren’t built to last forever, so unless you want to see your hot water access disrupted, it’s best to pre-empt water heating system failure by replacing units that are nearing the ends of their lives.

However, predicting water heater or boiler failure isn’t always easy, but there are things you can look out for so you know when your system is coming to the end of its life.


After years of service, lots of things can begin to go wrong with the parts in your water heating system. Parts wear out, corrosion develop and tanks can crack. For most makes of tank heaters, you can normally expect a life span of around 10 years.

So, knowing the age of your water heater is key to proactive replacement. If you don’t know when yours was installed or if you recently purchased your home, you can verify the date by checking the serial number label. Manufacturers note the month and year each unit is produced within the serial number, so you can refer to your water heater manufacturer’s website to identify your model’s code and confirm its age.


When your water heating system is on its way out, one of the first symptoms is that you will notice that the water coming from shower and taps is running cooler or is running out noticeably faster than before.

This could be due to a failing heating element, which a professional plumber can diagnose and repair. But it could also mean that mineral sediment has coated and hardened on the bottom of your tank, including the heating element. This tends to happen around or after the ten-year mark, and is a sign that your water heating system could be on its way out.

Regular servicing of your water heating system, including checking the anode rod and replacing it if necessary, will prevent tank corrosion. If you haven’t had the system regular serviced, then tank corrosion will be evident in the form of rusty coloured water coming from your taps.

You can confirm the problem is in your water heater and not your pipe system by getting a plumber to flush your water heater tank, another routine maintenance task, and checking to see if the drained water is rust-coloured. If your water heater is rusted out, it needs to be replaced before it springs a leak.

You should also check your water heater for leaks regularly and take action at the earliest sign of unexpected dripping or moisture.

Even if none of the above symptoms are evident, water heating could also be on its way out if there is a constant loud banging noise when it’s heating up. As sediment in the system settles and hardens, it forces your water heating system to work harder, and that can lead to rapid expansion of the tank for example. If you hear constant clanking coming from your tank, it’s time to get a new one.

  • A few Good Reasons To Choose A Boiler Service and even a Maintenance Plan

    July 23, 2020 |

    Let's take a look together at some vital elements of you home that can cause so much trouble and unnecessary stress when they break down or go out of order. The majority of people are depending on those key elements every day of their lives and not too often give them a 2nd thought until something wrong unexpected happens, and when it happens sorting that issue out can be very difficult, expensive and also time-consuming for most of us. Plumbing, gas and boiler services and maintenance plans have been designed to cover up these issues, so for a small monthly fee you can be protected against expensive costs of breakdowns that might occur at any time, any day. Right on our website, can sign up for one of three available affordable monthly plans that Jack The Plumber offers. The plans could cover regular boiler servicing / maintenance, that helps to prevent breakdowns before they actually happen, so any of our plans will give you that peace of mind knowing you're covered. As most people are always busy with their jobs and other household issues, they don't really think about their boiler until something goes wrong, and if they do think, that's because they either moved into a new home or they previously had such an incident that has happened to them in the past. COST SAVINGS: By paying on monthly basis a very small amount of money for regular maintenance it is a benefit. Think how much you would pay with a small plan of £5/month: that's 5x12= £60/year. If your boiler/central-heating breaks down (without being covered), you will have to pay a few hundreds of pounds, depending on the capacity of your boiler/central-heating. One of the biggest benefits to these plans is the huge amount of money you’ll save. If you have ever had a burst pipe or if your boiler has stopped working, you will know the cost of bringing out an emergency plumber. It’s a fact of life that turning to a tradesman in an emergency situation can be very costly, especially if your situation occurs out of hours or during a holiday. Basically, by paying that small monthly fee, you are protecting yourself against the emergency costs and save money with us. Instead of paying top price for a one-off service, you can save money by investing in one of our plans and be sure that you will not be charged emergency call out rates when your boiler develops a pressing issue in the middle of the night. REGULAR MAINTENANCE: Part of the money saving benefits of taking out a home maintenance plan is that you can start planning for the long term. Just like a car, a boiler should have regular servicing. But many people simply forget this fact. When the boiler stops working, in most instances many of the issues could have been caught at an earlier date through regular maintenance and servicing. These regular checks are best way to guard against emergencies in your home.
