Is it time to replace your boiler? 5 things you need to know

After 20 or 30 years, you might begin to wonder when it's wise to replace your boiler with a newer unit. Here are five things you should consider when trying to decide if it's time for a newer model or other type of heating system.

Even though the old boiler may be functioning well, you should evaluate its overall condition. Is the metal of the boiler still in decent shape? Do the doors still work well? The boiler's brickwork, burner and controls should also be inspected closely for signs of wear or breakdown. Having to address any of the conditions that occur with age often proves more costly than simply replacing the boiler.

An older boiler may function fine, but its doors can warp, and warped doors make the boiler smell bad. The gaps in the door allow it to release dirt, and carbon monoxide builds up in the boiler's room. In such circumstances, it becomes mandatory that you consider replacing the boiler even if it still functions because it poses a health and safety danger. Inhalation of excessive carbon monoxide can prove fatal.

It was not uncommon for oversized boilers to be used in the old days. If the boiler is too big, it will use too much energy to operate and cost more than simply replacing the boiler with the right size needed.

If a boiler is more than 20 years old, it probably lacks the energy efficiency of newer models. Replacing your old boiler with a new model will help you save on your energy bill.

If one part of a boiler system starts to leak, you might be tempted to just replace the pipe or area of the boiler that has sprung a leak, but you should take into consideration the fact that the boiler could be a leaking time bomb. If one section of the boiler or boiler pipes has rusted enough to leak, then chances are good that another area of the boiler or pipes will also start to leak. The cost of replacing parts and pipes can climb substantially and may not save you as much money as simply replacing the boiler.

It is not uncommon for parts on an older boiler system to become obsolete and unobtainable. This is especially true of boiler burners. Burners for an older model are difficult, if not impossible, to find. Ageing boiler burners also create excessive amounts of environmental pollution compared to new boiler burners.
