Boilers need regular care and attention otherwise you will one day wake up with no heating or hot water. There are signs that you can look out for that indicate you might need to start looking at new boiler.
Signs You Need A New Boiler
Radiators Take Longer Than Normal To Heat Up – Radiators may sometimes take hours to heat up, this could be a sign that your boiler is on its way out. Boilers will usually meet their maximum temperature very quickly. If your radiators are slow to heat up it could be caused by a blockage or cold spot, this would be easily remedied in your annual boiler service. However, if your radiators are still slow to warm up after the boiler has been serviced then it is likely that you will need a full boiler replacement.
Yellow Flame – Any healthy boiler will be burning a blue flame. A yellow flame could indicate that your boiler is leaking carbon monoxide. Carbon monoxide is a colourless and odourless gas that can cause serious illness and even be fatal. Symptoms of carbon monoxide poisoning include fatigue, nausea, headache, and dizziness. Have a gas safe registered engineer come out and inspect the boiler, it the leak cannot be repaired then it will be recommended that you get a new boiler.
Unusual Smell – Healthy boilers don’t give off any odours, so if it starts giving off a bad smell then it needs to be investigated. Bad smells can indicate burnt out parts and even gas leaks. It is best to get a gas safe engineer to inspect the boiler and they can advise whether you need a new boiler or just replacement parts for your existing boiler.
Increased Energy Bills – This can indicate that your boiler is not performing as efficiently as it should. The only way to remedy this is to have a new energy efficient boiler installed.
Boiler Keeps Turning Off – When your boiler keeps switching itself off it is trying to tell you there is a problem. It could be many things, low pressure, broken thermostat or even a pump issue. A gas safe engineer will be able to diagnose the cause and either replace the faulty parts or advise on getting your boiler upgraded.
Reduced Pressure – This is often an indication of a leak, and this can usually be resolved with a leak sealer, however if there is another cause to the pressure dropping it could be time for a new boiler.
Regular Breakdowns – If there is problem after problem with your boiler and you are regularly finding yourself without heating or hot water then it is definitely time for a new boiler, having new parts and repairs done will cost you a lot more money in the long run.
Discontinued Parts – If your old boiler has been well looked after and maintained it doesn’t mean it will last a lifetime. In a lot of cases parts for old boilers can be difficult to source as they have been discontinued, meaning if your boiler breaks down there will be no way of repairing it, therefore you will have no choice but to replace the boiler.
Boiler Making Noise – When a boiler is turned on, it makes a noise. It’s normally a constant hum that you might not even notice. However, if your boiler is clunking, banging or whirring, these sounds should alarm you. Unusual sounds can be because of a broken valve, pump problem or general wear and tear. If the noises your boiler is making are unusual you should switch it off and call out a gas safe registered engineer. The engineer will fix any minor issues, however if it is deemed unsafe then the engineer will recommend getting the boiler replaced.
Kettling – Kettling happens when the water flow is restricted because of limescale build up in the heat exchanger, it causes it to become hot and start steaming causing it to make a kettle like noise. Limescale and sludge build-up in the heat exchanger are common in areas where hard water is available. Boiler kittling is damaging. It reduces the lifespan of your boiler. Eventually, you will have to replace it because of frequent damage.
