Do I need to save for a new boiler?

Its been a long time since my last post. The main reason for this is I’ve been busy repairing boilers and heating systems and replacing boilers over these last few weeks. If you have a non – condensing boiler, specially if your boiler was installed before the year 2000 then its likely that the boiler is coming to the end of its life cycle. The average life cycle of a boiler is 15yrs.  If you have had your boiler serviced every year and the manufacturer of the boiler is a reputable one then your boiler could still be running fine, and it could last for up to 25yrs. However if the boiler has not been well maintained and it is a lesser known manufacturer then I would recommend saving for a replacement boiler. In 2005 it was made compulsory to install only condensing boilers due to them being a lot more efficient. This means it was not possible to buy an non – condensing boiler after 2005.

How do I know if I have a non – condensing boiler?

The main reason why condensing boilers are more efficient is because they extract more energy / heat out of the fumes that leave the boiler through the flue (chimney if you like) of the boiler. Due to more heat being taken out of the fumes condensing boilers have a plastic internal tube, which is fine because the fumes are not hot enough to melt plastic. A non – condensing boiler must have an all metal flue because the fumes are a lot hotter.

Here are a couple of pictures of old non – condensing, less efficient boilers.

If you are still uncertain if you have a condensing boiler or not, or you would like a boiler service would like a more efficient boiler then get in touch to arrange an appointment.
