When is the right time to get a new boiler?


The boiler is among those items which have to be extra reliable. Good and modern boilers can go up to 10-15 years of working based on usage. Also if the boiler is getting regular servicing by an engineer approved by the manufacturer, then there are more chances of getting a good lifespan of the boiler. If your existing boiler is approaching 10-15 years of age then start looking for the below points to support your decision of updating the boiler. Instead of making an urgent call to change the boiler, it should be better if we are ready with the working boiler in the summers only. 

Beyond Repair

You fix it when it breaks for the first time but if you are paying again if it is breaking for the 100th time. That indicates your boiler is irreparable and needs a replacement. Instead of paying for the repairs now and then, you can invest in a good modern boiler and stay tension-free for another 10 years. As the boiler gets old, it is difficult to get spare parts and they get more expensive also. There might be a chance that your total repair cost is the same as the new boiler. If your boiler needs continuous replacement, then it is calling for complete replacement.

Do you find leaks in your boiler? Do you find puddles around your boiler? Does your boiler give off an odd smell? 

Most of the noticeable points that call for a change are corrosion and cracks in the boiler. Non-uniform water circulation in the boiler can cause non-uniform heating. When overheated steel is made to drop temperature quickly by cooling, a crack may develop. Keep an eye on that. It’s best to get it fixed as soon as possible to avoid any type of major failure or mishaps

Update based on the requirements

Opt for the boilers and change the boilers based on the requirements. Households with high heating demand can opt for boilers with a higher KW output. With many new features coming up with thermostat settings users can always opt for easy settings boilers. 

Do people use hot water at once? Is hot water required throughout the year? Do you spend major time outside? Such questions from the installer can help them to understand your requirements. It will be worth it if you go ahead and update the engineer.  A knowledgeable Boiler engineer can help you in determining your requirements.

Use high energy efficiency rating

 With the advent of technologies, boilers with High energy efficiency ratings will affect your energy bills. The lower the rating the higher the energy bills. It is therefore advisable to house owners to invest in good boilers with high energy efficiency ratings. The UK government also insists on installing energy-efficient boilers to save the environment . so whenever it seems that energy bills are going up with the same amount of consumption, it might be because of your old boilers.

As per regulations, the boiler must have at least efficiency of 86% for gas and 85% for oil. An assessment is carried out by an installer on the type of boiler which is determined based on your requirements. The assessment procedures are mentioned in details in the Ministry of Housing, Communities and Local Government publication

Boilers won't stay efficient as they were in the beginning and need an up-gradation. The savings with energy-efficient boilers can cover your buying cost in the future.

Changing the location of the Boiler

If you are not happy with the place where your old boiler is installed and want to change it then it's better to go with a new one instead of changing the whole heating system. It will be helpful to inform the engineer if you are planning to rebuild the house or if you have anything in mind related to any improvements


Which is the best time of the year for Boiler installation?

You can do this whenever you feel it is the time to change. It is mostly used in winters so better not to wait till the season and get it done by summer when the weather is also warm. With winter and festivals around, it can be that expensive month of the year, so better to be done with this in summers only.  If your engineer tells you that the boiler needs to get changed and is unsafe to use now then better to do the work immediately. No need to worry if you have an external boiler since they are designed to understand the bad weather.


These all exercises seem overwhelming and can be tiring.  You can also hire an expert to look into your boiler and recommend the best way to upgrade without any hidden agenda.
