5 Signs Your Boiler Needs an Upgrade


The boiler is truly the hidden hero of the household providing heat to all rooms and keeping your bath running nice and warm. Usually tucked away either in a loft or in a kitchen cupboard and not given a second thought until it starts to give up. When your hot water tap is struggling to reach above luke warm it is defiantly time to get looking at what might be going on behind the casing of your forgot boiler. Here are some of the signs that you should start looking into getting a new boiler installed. Many of you will be under a cover care plan but often these do not cover you for a full replacement and you will find as your boiler ages parts are harder to source and the cover you have paid for becomes obsolete.

  1. Leaking Boiler – Water
    Like anything with moving parts over time things will wear. A boiler is no different. As soon as you notice any leaks it is important that you get an engineer to take a look. It could be a simple fix or you could need a whole new boiler. As well as property damage, a small leak can also lead to electrical faults by causing damage to other parts of the boiler ie the PCB Board (electrical center of the boiler), which is why you need to deal with the issue immediately as these parts can be considerably more expensive to replace than fixing the initial drip. A leak can be caused by failing valve or corroding pipework or a simple 20p o ring. Once you have had it fixed a service each year should help you keep a handle on things.
  2. Carbon Monoxide Danger / Maintenance
    A boiler that is working fine won’t emit any odour, even when your boiler is faulting you may not even detect an odour. Carbon Monoxide (odourless less) can be produced when your appliance isn’t burning its fuel correctly. It is highly recommended to have a Carbon Monoxide Alarm installed and positioned correctly in every home. It is worth noting that it’s the law in parts of the UK to have a working CO alarm fitted. If the alarm is sounded it is imperative that you isolate the appliance giving off the fume, ventilate the home and have a Gas Safe Engineer take a good look.

Carbon Monoxide poisoning is very serious and information can be found on the NHS website by following the link: https://www.nhs.uk/conditions/carbon-monoxide-poisoning/

In all new modern, room sealed condensing boilers you should not be able to detect any smells even when up close to the boiler as the air intake is pulled from outside and the products of combustion are released back outside. If you can detect a gassy odour you must report it immediately to the emergency gas number 0800 111 999.

  1. Increasing Energy Bills
    Many older boilers (non condensing) are at best 78% efficient the day they are produced. The efficiency of a boiler decreases between 0.5% and 1% per year it is in use. By upgrading to a new A rated energy efficient boiler you could save up to £325.00, for a detached property, off your gas bill per year.

Often if you are paying monthly for a cover care policy the money you are spending to cover your old boiler could equate to the same it would cost to pay monthly for a brand new boiler covered by its own warranty. If your energy bills have started increasing while your gas usage hasn’t changed, it could be because of an inefficient boiler. Our Energi House Surveyors are on hand to advise on a case by case basis. You may not always need a new boiler, some simple but effective housekeeping could increase your boilers’ lifespan. These include an annual services, filter installation and flushing your system.

  1. Strange Noises
    When firing up, all boilers make a slight noise, but this should be a low and constant hum. Whirring, clunking, and banging are the sounds that suggest a problem. These sounds could be due to pump problems, a broken fan, a faulty valve, or general wear and tear. Switch off the boiler if you are hearing strange noises and call an engineer to check what’s wrong. The boiler issue might be minor, but if it is not, our engineers may be able to source a replacement part for a fraction of the cost a full replacement boiler.
  2. Time For Your Home To Heat Up
    Are your radiators taking a lot of time to get hot or not heating fully? This could be because of a few things;
  3. Your boiler is not heating the water to a high enough temperature therefore the radiators are only feeling luke warm. This can be remedied by your boiler flow temperature being turned up.
  4. If you notice that only part of the radiator is heating up while other parts are still cold to the touch, this could be because there is a lot of sludge build up in your system and it needs to be flushed. The type of flush will be determined by the size, age and existing design of your system. We offer a range of flushes, from the cheapest and least intrusive chemical flush to a Power flush. This can add years on to the life of your current system.
  5. Not all radiators in the home are receiving heat. Checking all valves are fully open or have your current boiler assessed to confirm that it is correctly sized for your property could identify the root cause. Most modern boilers quickly reach their maximum temperature and produce heat instantly. If your boiler is taking hours to heat the home or the water isn’t getting as hot as it used to, it might be time for repairs or a full replacement.
