In most cases, there are only two reasons why you should replace a boiler: mechanical issues and running costs.
Mechanical issues can make a boiler unreliable and unsafe to run. Depending on how old and damaged a boiler is, the costs of repairing it may become unjustifiable. In some old and niche models, replacement parts may even be near-impossible to find.
This is an issue that can be mitigated by having a professional that offers boiler repair in Ayr inspect the boiler every year or so. A professional inspection can uncover issues before a part breaks, as explained on https://www.cnicolgas.com/boiler-repair-in-ayr.htm.
As for how running costs impact the decision to replace a boiler, this relates to the fact that newer boilers are almost always more efficient than older models. Thanks to that, a new boiler will often pay for itself in a few years by reducing how much you spend on heating every winter. Replacing an old boiler can also affect the resale value of a house, which is good to remember if you plan on selling the house in the near future.
