If your boiler is out of warranty, it’s worth considering whether repairing it is worthwhile
If your boiler has broken down before, its internal components could be getting towards the end of its life and your boiler could need subsequent repairs. The following could mean that replacing your boiler will be more cost-effective.
Your boiler age – Even if your boiler has run properly and efficiently for many years, nothing lasts forever and things break down over time. After serving you for all that time, the constant pressure and use have probably caused a lot of wear and tear, and even if it has not had problems up until it broke down, the sudden breakdown and emergency boiler repair might just be the tip of the iceberg, and the beginning of the end. If your boiler is at least 10-12 years old or more, it is likely to start costing you a lot in repairs.
Repair costs – You also have to factor in that repairs can cost a lot, particularly on older boilers. This is because if your boiler is older than 10-12 years, the parts are not likely to be as readily available. This may mean a headache in terms of money, and more importantly time, because you or your plumber may waste precious time looking for parts.
Energy efficiency – If your boiler is more than 12 years old, the chances are it’s a non-condensing boiler with highly worn down and corroded internal components, meaning it’s running at 50% to 60% efficiency. In monetary terms, this means you may be losing £30 to £40 per £100 spent on energy.
