If your boiler is older than 15 years, it is time to consider having a new boiler installed. Signs that your boiler is ageing include excessive noise during operation, reduced or delayed output of heat, and frequent breakdowns. If the annual cost of repairing your boiler is going to be more than half the cost of a new boiler, it is going to be in your best interest to replace the appliance. By installing a new boiler, you’ll benefit from the increased efficiency of a newer appliance and enjoy fewer issues, saving you money and headaches.
