As your boiler upgrade will be a big expense, make sure first that you actually need to replace it, rather than upgrade or replace old and worn parts. Call an engineer out to assess the overall health and efficiency of your current boiler, and if they can upgrade some of the moving parts or clean out filters and flues to help it work better then you mightn’t need to replace it just yet after all. As a guide, if your boiler is 15-20 years old, it is likely to need replaced, as the replacement parts will only get more expensive the older the make and model of your current unit.Â
